How to find CTOs with AI

  1. Step 1 of 3

    Describe your ideal CTO

    Type a sentence in plain English — stack, scaling stage, team size, industry, and exit history. No boolean filters or rigid title taxonomies. Lessie AI parses leadership-relevant context like prior IPO/M&A involvement, conference talks, GitHub footprint, and patent activity.

  2. Step 2 of 3

    Lessie AI builds a vetted leadership shortlist

    Lessie cross-references LinkedIn, GitHub, conference archives, engineering blogs, and patent databases in real time, deduplicates the same person across platforms, and verifies personal email deliverability before showing the result on your shortlist.

  3. Step 3 of 3

    Recruit in one workflow

    Send personalized recruiting outreach at scale, track who opened and replied, and move interested CTOs into your hiring pipeline — without leaving Lessie AI for a separate scraper, verifier, or ATS-adjacent sequencer toolkit.

FAQ

Get answers to common questions about Lessie AI.

What is an AI CTO finder?

An AI CTO finder is a tool that searches the open web in plain English to surface CTOs matching your criteria, then returns verified contact data. Lessie AI ranks results by relevance and fit instead of keyword filters, so a single query like a real description of who you need typically returns 50–200 qualified CTOs in under a minute.

How does Lessie AI find CTOs?

Lessie AI parses your natural-language brief, runs parallel searches across GitHub and dozens of other sources, then scores each CTO on signals like recency, topical fit, and audience overlap. The pipeline enriches each match with a verified email and a one-line context snippet, so you can review and reach out without manual research.

Where do the CTOs in the results come from?

Results are aggregated from GitHub, LinkedIn, Crunchbase, conference rosters, engineering blogs. Lessie AI re-crawls high-signal sources weekly and validates every email through SMTP and MX checks before showing it. You see the source URL next to each CTO, so you can click through and verify context yourself before sending outreach.

How is this different from LinkedIn Recruiter?

LinkedIn Recruiter is a curated database with fixed filters; Lessie AI is an open-web search engine driven by natural language. That means you can describe a niche CTO profile in one sentence and get fresh results pulled live, including people who never opted into a directory. You also get verified emails inline, not just profile links.

How is this different from AngelList Talent?

AngelList Talent relies on its own data warehouse refreshed on a fixed schedule, while Lessie AI searches the live web on every query and re-verifies emails on demand. That keeps results current and lets you find CTOs who appeared in news, podcasts, or GitHub last week. Pricing also scales by results delivered, not seat count.

Can I find CTOs for a niche tech stack or stage?

Yes — niche briefs are where Lessie AI outperforms keyword tools. Specify the tech stack or stage, geography, and any disqualifiers in plain English, and the engine runs targeted sub-searches across specialty sources. Most niche queries return 30–100 high-fit CTOs, and you can refine the brief inline if the first batch is off.

How accurate are the CTO email addresses?

Email accuracy averages 92–96% across CTO searches because Lessie AI runs catch-all detection, MX lookup, and SMTP handshake on every address before delivery. Invalid or risky emails are flagged so you do not waste sends. You only pay for verified contacts, and bounced emails are credited back automatically.

How much does it cost to find CTOs?

Lessie AI uses credit-based pricing — roughly one credit per verified CTO contact — with free credits to test the engine on your real brief before you commit. Most teams run 500–5,000 searches per month, and unused credits roll over. There are no seat fees or annual contracts, so you can scale up only when results land. Plug results straight into your [[/use-case/b2b-lead-generation|B2B lead generation workflow]] to start outreach the same day.
