Lessie AI

Lessie AI is an AI search tool. AI people search engine that turns natural language briefs into structured lists of influencers, B2B leads, investors, talent and partners, drawing on LinkedIn, Twitter, GitHub and over 100 other public sources.

Lessie AI is a people search engine that uses AI agents to locate individuals across a large set of public sources, including LinkedIn, Twitter, GitHub and more than 100 additional databases. Rather than returning a list of loose links, it accepts a natural language brief and works that brief into a set of matching people. Search descriptions on the site read like instructions: Los Angeles fitness creators who post workout or nutrition content, seed stage investors focused on generative AI startups, or senior product designers with strong UX portfolios. The agent interprets the criteria, gathers matches from connected data providers, and returns structured profiles. The product is organized around five commercial use cases: influencer discovery, B2B lead generation, investor sourcing, recruiting, and partner or distributor search. Marketing teams use it to build creator shortlists, founders use it to assemble investor lists, and sales or recruiting teams use it to surface prospects with public contact information. A dedicated recruiting flow, a partnerships flow, and a lead generation flow each frame the same engine around a different target audience. In practice, the workflow starts with a plain language query. Results appear as profiles, and a companion lists product at lists.lessie.ai suggests results can be saved into working collections, while a profile viewer at profile.lessie.ai handles lookups of individual public profiles. The site also ships a wide toolbar of supporting utilities, including email finders and verifiers, follower authenticity checks, engagement calculators, cold email and subject line generators, ICP scoring, and Boolean search builders for recruiters. These small tools round out the core search rather than replace it. Lessie positions itself against general AI assistants and web search APIs. Its own benchmark page scores 119 real queries across platforms, and the company reports an overall score of 65.2 versus 55 for Exa, 46 for Claude and 45.8 for Juicebox. That comparison is vendor published, so treat it as a directional claim. The strongest fit is a team that needs repeatable people lists in a specific vertical and wants the surrounding outreach utilities in one place.
