For teams building AI agents and automated outreach

Verified contact data
for your AI agents,
via API or MCP.

Cheap AI made outreach agents easy. The bottleneck is data. Lessie gives your agents real-time verified emails and enriched company records from 800M+ profiles — so they reach real people.

Why agents fail without real data

A cheap AI agent still can’t reach a person it can’t find.

Static contact databases go stale and generic scrapers bounce. Lessie resolves and verifies the contact in real time and serves it straight to your agent — via API or MCP.

How it works

From a name to a verified, agent-ready contact. In one call.

01

Send a lead, company or query — from your agent or app.

Call the Lessie API or wire the MCP connector into your AI workflow. Pass a name, a company, or a plain-language target.

02

Lessie resolves and verifies in real time.

It searches 800M+ profiles, resolves the right person, verifies the email on the spot, and enriches with firmographics and tech stack — no stale snapshot.

03

Your agent reaches a real person.

Structured, verified contact data flows straight back to your agent or SDR — so automated outreach lands in a real inbox instead of bouncing.

Why this matters

Inference got 100x cheaper — so the moat moved from compute to data. An AI outreach agent is only as good as the contact it can verify. Lessie is the verified-data layer that makes agentic outreach actually reach people.

FAQ

Get answers to common questions about Lessie AI.

What is verified contact data for AI agents?

It is contact data an AI agent can trust at request time: the right person resolved from 800M+ profiles, with an email verified in real time plus firmographic and technographic enrichment. Lessie serves it via API or an MCP connector so your agent reaches real people, not bounced inboxes.

Can I plug Lessie into my AI agent or MCP workflow?

Yes. Use the REST API or the MCP connector to give any agent, assistant or SDR tool verified contacts and enrichment on demand — the data layer for agentic prospecting and outreach.

How fresh and accurate is the data?

Contacts are resolved and verified in real time at request, not read from a stale export — 95%+ email accuracy, with direct dials when available. That is the difference between an agent that reaches people and one that bounces.

Can it enrich my existing lead list or CRM?

Yes. Send a lead list or CRM records and Lessie enriches each with verified email, firmographics and tech stack — data enrichment and hygiene for your whole pipeline, in bulk.

How is this different from buying a contact list?

A bought list is a stale snapshot resold to everyone. Lessie resolves and verifies on demand and returns structured data to your agent — current, per-request, and covering 800M+ global profiles.

Is there a free way to try it?

Yes. Start free with no credit card, enrich real records and see verified contacts before you pay — the paid plan unlocks API volume and MCP access at scale.

Give your agents data they can trust.
