How to Reach CTOs by Phone and Book the Technical Meeting

How to Reach CTOs by Phone and Book the Technical Meeting

If you sell B2B technology and you cannot effectively engage CTOs, you are losing deals you should be winning.

I have worked with dozens of B2B tech companies on their outbound motions, and the pattern repeats itself constantly. The sales team books a meeting with a VP of Engineering or a Director of Product. The conversation goes well. There is genuine interest. Then the prospect says, "I need to loop in our CTO." And the deal stalls. Or worse, the CTO kills it in a single internal conversation that your sales rep never even gets to join.

CTOs are among the most influential buyers in any B2B technology sale. They sit at the intersection of business strategy and technical execution. They control budgets. They shape the technology roadmap. They have veto power over virtually every tool, platform, and vendor that enters their organisation. And yet most sales teams treat them like any other executive buyer, which is exactly why they fail to engage them. Forrester research on B2B buying consistently shows that enterprise purchases now involve six to ten stakeholders, and in technology deals the CTO is almost always the most consequential vote.

Reaching CTOs requires a different approach. You need to understand how they think, what they care about and how they evaluate vendors, then earn a few minutes on the phone with a reason that matters to them. This guide is written for the SDR side of that job: getting the CTO, or their engineering leaders, on the phone and booking a technical meeting your AE and solutions engineer can win.

It pairs with a phone-led outbound sales strategy that targets technical leadership.

Understanding the CTO Persona

Before you make a single call, you need to understand what drives a CTO. Not what you think drives them, what actually drives them.

CTOs are not a monolithic group. A CTO at a 50-person startup has very different concerns than a CTO at a 5,000-person enterprise. But there are universal priorities that cut across almost every CTO I have worked with or sold to.

Priority 1: Scalability

CTOs think in terms of systems that need to grow. They are constantly asking, "Will this still work when we are ten times our current size?" Every technology decision they make is evaluated through this lens.

This means they are deeply sceptical of solutions that work beautifully for small teams but have no clear path to handling enterprise-scale workloads. If your product cannot articulate how it scales, architecturally, operationally, and commercially, the CTO will move on.

When you are selling to a CTO, you need to speak to scale from the first touchpoint. Not in vague marketing terms like "built to scale", in concrete architectural terms. How does your platform handle increased load? What is your multi-tenancy model? How do you manage data partitioning? These are the questions running through a CTO's mind before they even reply to your email.

Priority 2: Security and Compliance

Security is non-negotiable for any CTO. They are personally accountable for the security posture of their organisation's technology stack. A data breach or compliance failure does not just affect the company, it affects the CTO's career.

This means that any vendor selling to a CTO needs to lead with security credentials, not bury them on page four of a pitch deck. SOC 2 Type II, ISO 27001, GDPR compliance, encryption standards, access control models, audit logging, these are not nice-to-haves. They are table stakes.

If you are selling to CTOs at companies in regulated industries, fintech, healthtech, govtech, the bar is even higher. You need to demonstrate that you understand their specific compliance frameworks and that your product was built with those constraints in mind, not retrofitted to meet them. If you also sell to CISOs, the security conversation overlaps significantly, read our guide on selling to CISOs for the security-specific playbook.

Priority 3: Integration and Interoperability

CTOs do not buy tools in isolation. They buy tools that fit into an existing ecosystem. Every new vendor adds complexity to an architecture that the CTO is responsible for maintaining.

The question they always ask is, "How does this fit with what we already have?" If you cannot answer that question clearly, you will not make it past the first conversation.

This means you need to understand the CTO's existing tech stack before you reach out. What CRM do they use? What cloud provider? What CI/CD pipeline? What observability tools? The more you know about their environment, the more credibly you can position your solution as something that integrates cleanly rather than creating yet another silo. Sourcing this level of detail reliably is a data-quality problem, vendors such as Cognism have built dedicated technographic and human-verified contact datasets precisely because off-the-shelf B2B records rarely hold up under technical scrutiny.

APIs, webhooks, native integrations, SSO support, data portability, CTOs evaluate all of these before they evaluate your core features. Get the integration story wrong and features become irrelevant.

Priority 4: Team Productivity and Developer Experience

CTOs manage engineering teams. Their success is measured partly by how productive those teams are. Any tool that slows developers down, creates friction in workflows, or requires extensive training is a tool the CTO will reject.

Developer experience matters enormously to CTOs. If your product has a clunky UI, poor documentation, a steep learning curve, or an API that developers dread working with, the CTO will hear about it from their team, and that feedback will kill your deal.

Conversely, if developers love your product, if it makes their lives easier, if the docs are excellent, if the API is elegant, you will have internal champions pulling the CTO toward a purchase decision. The best way to sell to a CTO is often to win over their engineering team first.

Priority 5: Total Cost of Ownership

CTOs think beyond the sticker price. They calculate the total cost of ownership, licensing fees, implementation effort, integration development, ongoing maintenance, training time, and the opportunity cost of engineering resources spent on adoption.

A product that costs $50,000 per year but requires three months of engineering effort to implement has a very different TCO than a product that costs $80,000 per year but can be deployed in a week. CTOs understand this math intuitively. Your pricing conversation needs to account for it.

How CTOs Evaluate Vendors

Understanding a CTO's priorities is step one. Understanding their evaluation process is step two. CTOs do not follow the same buying journey as a CMO or a VP of Sales. Their process is more methodical, more technical, and more consensus-driven.

The Research Phase

CTOs do their own research before they ever talk to a vendor. They read engineering blogs. They check GitHub repositories. They look at Stack Overflow discussions. They ask their network, other CTOs, engineers they trust, technical advisors.

By the time a CTO takes a meeting with you, they have already formed an initial opinion of your product. They have read your documentation. They may have tried your free tier. They have almost certainly looked at your competitors.

This has a critical implication for your sales process: your public-facing technical content is doing selling before your sales team even gets involved. If your documentation is poor, your engineering blog is empty, and your API reference is outdated, you have already lost credibility before the first meeting. According to the Salesforce State of Sales report, buyers complete a significant share of their evaluation independently before ever speaking with a vendor, and that share is even higher for technical buyers.

The Technical Validation Phase

Once a CTO is interested enough to engage, they move into technical validation. This is where most deals with CTOs are won or lost.

Technical validation typically involves:

• Architecture review: The CTO (or their senior engineers) will want to understand your product's architecture. Not a marketing-level overview, the actual technical architecture. How is data stored? What is the latency profile? How do you handle failover? What is your deployment model?
• Security assessment: A formal or informal security review. This could range from a security questionnaire to a full penetration test, depending on the deal size and the CTO's risk tolerance.
• Integration assessment: Can your product connect to their existing stack? Is the API well-documented? Are there SDKs in the languages their team uses? How robust is the webhook system?
• Reference checks: CTOs talk to other CTOs. They will ask for references, and not just the hand-picked ones you provide. They will reach out through their own network to find customers who will give them an unfiltered assessment.

The Consensus Phase

CTOs rarely make purchasing decisions alone. Even when they have full budget authority, they build consensus with their engineering leadership team. A CTO who forces a tool on a team that does not want it creates friction, resentment, and adoption failure.

This means your sales process needs to account for multiple stakeholders within the engineering organisation. The CTO may be your economic buyer, but the VP of Engineering, the Principal Architect, and the team leads all have influence. Win them over, and the CTO's decision becomes easy. Ignore them, and you are fighting an uphill battle. Sharpening the B2B sales discovery questions you use across the technical committee makes this multi-stakeholder motion far more tractable.

Reaching CTOs by Phone

CTOs are among the hardest personas to reach cold. Their inboxes are overflowing, they ignore most LinkedIn messages, and many have assistants who filter their communications. A short, researched phone call is one of the few approaches that still cuts through, as long as it is precise, credible and relevant.

Get Past the Filter

Treat an executive assistant as an ally: be clear about who you are and give the one-sentence technical reason the call matters. Assistants often point you to the VP of Engineering or Principal Architect who owns the problem, which is frequently the better first conversation. Call early in the morning or late in the afternoon, outside the meeting blocks, and vary the time across attempts.

Lead With Technical Value, Not Business Value

The single biggest mistake callers make with CTOs is leading with business outcomes. "We help companies increase revenue by 30%" means nothing to a CTO. That is a message for a CRO or a CMO.

CTOs care about technical outcomes, so the opener should name one:

"Hi [Name], it's [SDR] from [Company]. I saw your team is hiring platform engineers to work on deployment tooling. We work with engineering teams on exactly that bottleneck. Have you got 30 seconds for me to explain why I called?"

Notice the pattern: specific, technical, evidence-based. No vague promises. No business buzzwords. If your company has published an engineering post, benchmark or open-source tool relevant to their stack, that is a credible reason for the call. Our cold calling scripts cover the structure of the rest of the call.

Multi-Thread the Organisation by Phone

Do not rely on a single thread to the CTO. Call the CTO while also calling their engineering leaders. When a CTO hears about your product from their own team, "Hey, I've been looking at this tool and it could solve our deployment bottleneck", your next call to the CTO has context and internal validation. Analysis on the HubSpot Sales blog consistently highlights multi-stakeholder engagement as one of the strongest predictors of close rate in complex deals.

A practical multi-threading cadence:

1. Week 1: Call 2-3 senior engineering leaders with a specific technical reason. No pitch, just a relevant question.
2. Week 2: Call the CTO, referencing a specific technical challenge at their company (gleaned from job postings, engineering blog posts, or conference talks their team has given).
3. Week 3: Call the CTO again, and reference any conversation you had with their team.
4. Week 4: Ask for a specific technical meeting with your solutions engineer, with the engineering leader you spoke to invited too.

This takes patience, but it converts at a far higher rate than repeated calls to the CTO alone.

Book the Right Meeting

The SDR's job is to book a technical meeting, not to run the demo. Agree the problem to be discussed, who from their team should attend, and that your solutions engineer will be there. Put that in the calendar invite. A CTO who knows the meeting will be engineer-to-engineer is far more likely to show up.

Building Technical Credibility

You cannot fake technical credibility with a CTO. They will see through it immediately. If your sales team does not understand the technology they are selling, the CTO will disengage within minutes.

Invest in Technical Sales Engineering

Your sales reps do not need to be engineers. But they need to be technically fluent, able to discuss architecture at a high level, understand the CTO's technical concerns, and know when to bring in a solutions engineer for deeper conversations.

The best B2B tech companies pair every enterprise seller with a dedicated solutions engineer or sales engineer. This person joins discovery calls, runs technical demos, handles architecture discussions, and answers the hard questions that a CTO will inevitably ask.

If you do not have dedicated sales engineers, you are going to struggle to close deals where the CTO is the decision-maker. Full stop.

Publish Engineering Content

Your company's engineering blog is one of your most valuable sales assets when selling to CTOs. Publish content that demonstrates genuine technical depth:

• How you solved a specific scaling challenge
• Your approach to data security and encryption
• Post-mortems on incidents and what you learned (this one is counter-intuitive, but CTOs deeply respect transparency about failures)
• Benchmark data comparing your approach to alternatives
• Open-source contributions and tools your team has built

When a CTO evaluates your company, they will look at your engineering blog. If it is empty or filled with superficial marketing content, that tells them something. If it is filled with genuine, in-depth engineering writing, that tells them something very different.

Bring Engineers Into the Sales Process

There is no substitute for engineer-to-engineer conversation. When a CTO has a deep technical question, the most credible person to answer it is one of your engineers, not your sales rep, not your marketing team.

The companies that win CTO deals consistently are the ones that make their engineers accessible during the sales process. This does not mean pulling engineers away from product work for every deal. It means having a structured programme where engineers participate in key technical conversations for high-value opportunities.

Some companies create a rotating "customer engineering" role where engineers spend one week per quarter supporting sales. Others have dedicated developer advocates who bridge the gap between engineering and sales. The format matters less than the principle: CTOs want to talk to the people who actually build your product. If you're also targeting the security buyer in the same account, our guide on selling to CISOs walks through how the two personas differ and where the messaging needs to diverge.

After the Meeting Is Booked: Handing Over to the AE and SE

The demo, technical evaluation and any POC belong to your AE and solutions engineer. What the SDR controls is the quality of the handover. Before the meeting, pass on:

• The specific problem the CTO or engineering leader agreed to discuss, in their words
• Who is attending and their roles, plus anyone they said should be involved later
• What you learned about their stack from the call and your research
• Any build-vs-buy signals you heard, because that objection is coming

A CTO who arrives to find the team already understands their environment starts the evaluation with trust rather than scepticism.

Common Mistakes When Selling to CTOs

I have watched hundreds of deals involving CTOs. These are the mistakes I see most often.

1. Leading With Features Instead of Problems

CTOs do not care about your feature list. They care about the problems they are trying to solve. If you lead with "our platform offers real-time data streaming, automated scaling, and 200+ integrations", the CTO is already tuning out. Lead with the problem: "Your engineering team is spending 30% of their time on infrastructure management instead of building product features. Here's how [similar company] eliminated that."

2. Overselling and Under-Delivering

CTOs have excellent pattern recognition for vendors who overstate their capabilities. If you claim your product does something it does not do well, the CTO will find out during the evaluation, and you will lose all credibility. It is far better to be honest about limitations and strong on what you genuinely do well.

3. Ignoring the Engineering Team

If you are selling exclusively to the CTO and ignoring the engineers who will actually use your product, you are building a deal on a fragile foundation. Even if the CTO signs the contract, poor adoption by the engineering team means the deal churns at renewal. Engage the engineers early and often.

4. Using Non-Technical Sales Reps Without Support

Sending a sales rep who cannot hold a technical conversation into a meeting with a CTO is a waste of everyone's time. CTOs will ask technical questions within the first five minutes. If your rep cannot answer them, or worse, tries to bluff through them, the meeting is effectively over. Always pair your rep with a solutions engineer for CTO meetings, and tell the CTO that when you book the meeting.

5. Failing to Follow Up With Technical Depth

After a meeting with a CTO, the follow-up matters as much as the meeting itself. Sending a generic "great to connect, here are the next steps" email is a missed opportunity. Instead, send a follow-up that includes the technical answers to questions raised, links to relevant documentation, architecture diagrams discussed, and a clear evaluation plan. Show the CTO that you took their technical questions seriously.

6. Treating the CTO Like Every Other Executive

A CTO is not a CFO who happens to work in technology. Their decision-making framework is different. They evaluate vendors through a technical lens first and a commercial lens second. Your sales process needs to reflect this. If your standard enterprise sales playbook does not have a specific track for technical buyers, build one.

7. Not Preparing for Objections About Build vs. Buy

Every CTO considering your product has thought about building the same thing in-house. "We could build this ourselves" is the most common objection you will face when selling to CTOs. You need a compelling, specific answer to this objection, one that addresses the total cost of building, maintaining, and scaling an internal solution versus buying yours. Factor in engineering time, ongoing maintenance, opportunity cost, and the risk of building something that is not your core competency.

8. Neglecting Post-Sale Technical Relationships

Selling to a CTO does not end at contract signature. CTOs expect ongoing technical engagement, product roadmap visibility, early access to new features, a direct line to your engineering team for critical issues. If you disappear after the deal closes, you will churn. The companies that retain CTO-driven deals long-term are the ones that maintain a genuine technical partnership well beyond the initial sale.

Most of the mistakes above surface as objections in-cycle rather than pre-deal, our objection handling framework covers how to defuse the technical variants in real time.

Frequently Asked Questions

How is selling to a CTO different from selling to other C-suite executives?

CTOs evaluate vendors primarily through a technical lens. While a CFO focuses on ROI and a CMO focuses on growth metrics, a CTO is assessing your architecture, security posture, integration capabilities, and engineering quality. They want to speak with your engineers, not just your salespeople. Your sales process needs a dedicated technical track with solutions engineers, architecture documentation, and hands-on evaluation opportunities that other C-suite roles typically do not require.

What is the best channel for reaching CTOs cold?

The phone. CTOs ignore most cold email and LinkedIn messages, but a short, researched call that leads with a specific technical observation stands out. Reference something concrete about their stack, architecture or public engineering content, ask for 30 seconds, and make the ask specific: a technical conversation with your solutions engineer. Call their engineering leaders too. For the wider framework, see our phone-led outbound sales strategy guide.

How technical does my sales team need to be to sell to CTOs?

Your account executives do not need to be former engineers, but they need to be technically fluent, able to discuss architecture at a high level and ask intelligent discovery questions. The non-negotiable is having dedicated solutions engineers or sales engineers who can go deep on technical conversations. A CTO will ask questions about uptime, data handling, security protocols, and API design within the first meeting. Someone on your team needs to answer those questions credibly.

How do I handle the "we can build this ourselves" objection?

This is the most common objection from CTOs. Address it by quantifying the true cost of building in-house: engineering headcount, development time, ongoing maintenance, opportunity cost of diverting engineers from core product work, and the risk of building something that is not your company's core expertise. Present case studies of companies that chose to buy rather than build and the outcomes they achieved. Often, the CTO has already estimated the build cost internally, your job is to surface the hidden costs they may have underestimated.

What should I include in a follow-up email after a CTO meeting?

Include specific technical answers to questions raised during the meeting, links to relevant architecture documentation, security certifications and compliance details, a proposed evaluation plan with timelines, and an offer to connect their engineering team with yours for a deeper technical discussion. Avoid generic sales language. The follow-up should read like a technical memo, not a marketing email. This demonstrates that you took their questions seriously and have the depth to back up your claims.

How long does a typical CTO sales cycle take?

CTO-involved deals typically take 3-6 months for mid-market and 6-12 months for enterprise. The technical evaluation phase alone can take 4-8 weeks, including POC or pilot periods. You can compress this timeline by making the evaluation process frictionless, providing sandbox environments, comprehensive documentation, and dedicated technical support. Companies that invest in their evaluation infrastructure close CTO deals 30-40% faster than those that rely on manual, ad-hoc evaluation processes.

Should I offer a free POC or charge for it?

For deals under $100,000 ACV, a free time-boxed POC (2-3 weeks) is standard and expected. For deals above $100,000 ACV, a paid pilot signals mutual commitment and seriousness. Paid pilots also tend to receive more internal attention from the CTO's team, when budget is allocated, people prioritise the work. Regardless of whether the POC is free or paid, always define success criteria upfront. An unfocused POC without clear goals wastes time for both sides and rarely converts to a contract.

How do I build relationships with CTOs before I need to sell to them?

Invest in long-term technical community engagement. Publish genuine engineering content, architecture posts, benchmark analyses, open-source tools. Speak at technical conferences and meetups where CTOs attend. Build a reputation as a technically credible company before you ever need to sell. When the time comes to reach out, the CTO already knows your name and respects your technical depth. This approach takes months to build, and it makes every cold call easier because your SDR can reference work the CTO may already have seen.

Start Reaching Technical Decision Makers

Selling to CTOs is not about being the slickest salesperson in the room. It is about being the most technically credible, the most transparent, and the most prepared. CTOs respect companies that understand their world, the engineering challenges, the architectural trade-offs, the pressure to keep systems secure and scalable while shipping product fast.

If your team is not currently equipped to engage CTOs effectively, start with the fundamentals. Invest in solutions engineering. Give your SDRs a specific technical reason for every call. And call the engineering team, not just the CTO.

If you want experienced, Australian-based SDRs calling CTOs and other technical decision-makers on your behalf and booking the technical meeting, that is exactly what our SDR agency for B2B tech and cold calling service deliver. Your team focuses on running demos and closing deals.

The CTOs you want to reach are evaluating vendors right now. Make sure your company is one they take seriously.
