CTO Email Finder
Find the verified email of any company's Chief Technology Officer by domain — no name needed. Whether you are recruiting senior engineers, selling dev tools, or pitching a tech partnership, the Decision Maker endpoint gets you the right contact, verified live via SMTP.
Why reach the CTO directly
The CTO controls the technology stack and signs off on infrastructure, tooling, and engineering hires. If you are selling a developer tool, proposing a technical partnership, or recruiting for a senior engineering role, the CTO is often the only person who can say yes — and the last person a generic inbound form reaches.
Direct email is still the most effective channel for CTO outreach. Cold LinkedIn DMs have low reply rates for senior technical leaders. A concise, relevant email to the right inbox gets results that most other channels cannot match.
How it works
Pass the company domain to the Decision Maker endpoint with role category cto. The API identifies the person currently in the CTO seat, generates and tests the most likely email patterns at that domain, and verifies each candidate address against the live mail server via SMTP. Only a confirmed, deliverable address is returned — along with the person's name, job title, and LinkedIn URL when available.
If no CTO can be identified or their email cannot be verified, the API returns not_found and you are not charged. You only pay for results you can actually use.
