How do you find CTO contacts at target companies?

Who decides when a CTO is involved

Who decides depends on company size: the CTO decides at a small company and approves at a large one. With a dozen engineers, the CTO still reviews code, picks the stack and signs off developer tools personally. As the engineering organisation grows, the CTO turns to architecture, hiring and the product roadmap, and hands tool choices to the leaders who run teams.

In a larger buying group the CTO is often the technical veto. A VP of engineering or head of platform runs the evaluation, a staff or principal engineer tests the product, and the CTO approves anything that touches production systems, customer data or the architecture.

Which titles cover CTO and VP engineering contacts

Search the CTO title together with the engineering leaders who make the choice in larger companies.

Use C-suite seniority for the CTO and VP or director for the evaluators, and add keywords that describe the team, such as platform, infrastructure or developer tools, to keep results close to your product.

• Startups and small scale-ups: chief technology officer, technical co-founder, head of engineering.
• Mid-sized and larger software companies: VP of engineering, engineering director, head of platform, head of infrastructure.
• Specialist owners: head of data engineering, security engineering or developer experience, depending on what you sell.
• Companies that do not sell software: the CTO may be a chief digital officer, or sit beside a CIO who owns internal IT.

Which signals show an engineering team will buy

An engineering team is ready to look at a new tool when its job adverts, public code or posts reveal a problem your product solves. Job adverts are the clearest signal: they list the languages, cloud providers and tools a team uses, and a new role in platform, reliability or data engineering shows where money is going. Engineering blogs, conference talks and public repositories add detail.

A migration, such as a move between cloud providers or splitting a monolith into services, opens many tool decisions at once. Funding rounds and product launches bring hiring and pressure to ship faster, and a newly appointed VP of engineering usually reviews the toolchain in their first months.

How to reach a CTO without sounding like marketing

Reach a CTO with a first line that shows you understand their stack and their problem, then stop. Engineering leaders skip adjectives and respond to specifics: the integration you support, the failure you prevent, the trade-off you made. Two or three sentences, a link to documentation rather than a brochure, and an offer to let one of their engineers try it are enough.

As an illustration only, a vendor of database monitoring might reply to a team's blog post about adding read replicas, note that replica lag per query is the thing that usually surprises teams after that change, and link the relevant documentation page. Many CTOs read LinkedIn and developer communities, so a short message that answers something they wrote reads as a conversation rather than a pitch.

Which security questions will a CTO ask

A CTO will ask how your product reaches their systems, where their data goes and what happens if something fails, so write the answers down before the first call.

• Which permissions it needs, and whether they can be limited to read only.
• Where data is stored and processed, and which sub-processors are involved.
• How sign-in works, including single sign-on and role-based access.
• Whether customer data trains any model, if your product uses AI.
• Which security reports or certifications you hold, with target dates for any that are pending.

Can you use a CTO email address found in public code

Use only a CTO's work address for sales outreach, not the personal addresses developers publish in code commits or package registries. Those details were shared for collaboration, not for sales email, and using them weakens any claim that your message is a reasonable approach to someone in their business role.

For the work address, legitimate interest under GDPR can cover relevant B2B outreach. Record your assessment, say where you found the person's details, include an opt-out and remove anyone who uses it. In the UK, PECR applies to the email as well. Take advice on your own situation; this is not legal advice.
