2

Lessie scans LinkedIn, Y Combinator, Product Hunt, recently funded lists, company sites, and more — no manual filter clicking required.

3
Get Verified Contacts

Every result includes decision-maker info (founder, CTO, PM) with verified email, role, company context, and a relevance score.

4
Export or Reach Out

Push to HubSpot, Instantly, Lemlist, or CSV. Use AI-drafted personalized pitches, or let your team take it from here.

Built for Finding Early Adopters, Not Enterprise Leads

Apollo optimizes for bulk B2B lists. Crunchbase optimizes for investor research. Lessie optimizes for the founder's first-100-users problem.

🎯
Criteria That Directory Filters Can't Handle

Early-adopter searches are rarely "SaaS companies in NYC." They're "SaaS founders in fintech, Series A, launched product in the last 6 months." Lessie's AI parses compound criteria the way a human analyst would.

  • Natural language queries with stage, vertical, geo, timing
  • Multi-source fusion: company data + people data in one pass
  • Scored, ranked results — not a raw dump
Decision-Makers, Not Just Companies

Crunchbase tells you a startup exists. Lessie tells you exactly who to email. Every result includes founder/CTO/PM contacts with verified direct emails — 95%+ deliverability.

  • Founders, CTOs, Heads of Product identified by role
  • 95%+ email verification rate
  • Context on company stage, funding, team size
From Query to Outreach in Minutes

Stop spending 6+ hours per week on manual prospecting. Type a query, get a ranked list in under a minute, export to your outreach tool, start sending.

  • Under 60 seconds per list
  • 1-click export to HubSpot, Pipedrive, Instantly, Lemlist, Apollo

🔍
Built for Early-Stage Research

Other tools focus on enterprise or SMB. Lessie indexes the signals early adopters leave: YC batches, Product Hunt activity, recent funding, hiring patterns, and founder profiles.

  • Y Combinator, Techstars, and accelerator alumni databases
  • Recently funded startups (seed → Series B)
  • Product Hunt makers and indie founder communities

FAQ

Get answers to common questions about Lessie AI.

How does Lessie AI find early adopters for my product?

Lessie AI uses an agentic search engine that scans 100+ data sources including LinkedIn, Y Combinator, Product Hunt, Crunchbase-style databases, company websites, and professional networks. When you describe your ideal early adopter — for example, "SaaS founders in fintech who raised seed in the last 6 months" — the AI identifies matching startups, finds the right decision-makers (founders, CTOs, product leads), and delivers verified email addresses and direct contacts. Each result includes a relevance score so you can prioritize outreach.

Why use Lessie instead of Crunchbase or LinkedIn?

Crunchbase gives you company data but no direct contacts — you still need another tool to find and verify emails. LinkedIn Sales Navigator requires manual filtering and limits searches. Lessie AI combines both layers: startup/company discovery + verified decision-maker contacts, in one natural-language query. You skip 6+ hours of manual research per list.

What kinds of early adopters can I find?

Anything you can describe in English: recently funded SaaS startups, founders at Y Combinator companies, CTOs in specific verticals (fintech, healthtech, devtools), product managers at post-Series-A companies, indie makers with certain Product Hunt activity, or founders raising seed rounds right now. Lessie handles complex multi-criteria queries that directory-style filters cannot.

How accurate are the contact details?

Lessie AI verifies every email address in real-time before delivery, with 95%+ deliverability. We prioritize direct work emails over generic info@ addresses. If a contact bounces, it is replaced automatically.

Can I export results to my outreach tool?

Yes. Export to CSV, or push directly to HubSpot, Pipedrive, Instantly, Lemlist, Apollo, and other popular outreach tools. Lessie is the data source layer — your existing cold-email stack keeps sending.

How fast can I get my first list?

Under 60 seconds. Describe who you want in natural language, Lessie searches in real time, and you get a scored list of verified contacts you can export or act on immediately. No imports, no CSV uploads, no "wait for enrichment".
