I was today days old when I learned there's an AI that will find a specific person for you — when all you can give it is a vague description in plain English.
It's called Lessie AI, and the pitch is simple: type a sentence describing who you want to find, and the AI goes digging across 100+ data sources — LinkedIn, X/Twitter, GitHub, YouTube, TikTok, Instagram, podcasts, company databases, the works — and hands you a ranked list of matching people, usually with contact info attached.
Here's what makes it interesting:
- You describe the person, not the keywords. Traditional people search is a keyword boolean exercise: "founder" AND "seed stage" AND "Seattle" NOT "retired". Lessie lets you type it the way you'd ask a smart friend: "designers I worked with at startups in 2018" or "YouTubers in the 100k-500k range who cover indie game dev" or "CFOs of pre-Series-B SaaS companies who posted about pricing recently." It figures out what you mean.
- It hits 100+ sources in one pass. This is the part that's hard to appreciate until you use it. A normal search might scrape LinkedIn and call it a day. Lessie cross-references LinkedIn with X posts, GitHub activity, podcast appearances, Substack bylines, and company databases to build a fuller picture of each person. Somebody might be invisible on LinkedIn and obvious on GitHub, or vice versa.
- Contact accuracy claimed around 95%. You get verified emails and, where possible, direct social handles. That's the piece that turns this from "search tool" into "workflow" — you're not just finding names, you're finding a way to reach them.
- Built-in outreach with templates. Once you have your list, you can fire off personalized emails or DMs directly from Lessie using customizable templates. The AI helps tailor each message using what it scraped (their recent posts, their company, their role). Sales and recruiting teams will immediately see the appeal.
- It's free to start. No credit card. You get a free tier with a chunk of credits to burn through — enough to figure out whether it's useful for you before committing to a paid plan. Paid tiers unlock more searches, more contact unlocks, and higher-volume outreach.
The honest take: it's not perfect. We hit sporadic server errors during our test runs — queries that timed out, occasional 500s when things got busy. It's clearly a newer tool still sharpening the edges. But when it worked, it really worked. The kind of "oh, that's actually the right person" results that you'd normally only get after forty-five minutes of LinkedIn sleuthing.
The surprise use case: it's also shockingly fun for tracking down people you used to work with. Type something like "engineers I worked with at [old company] around 2016 who have since started their own thing" and watch a list of familiar names appear — some with new job titles, some with podcasts you didn't know they had, some who are now CEOs of companies you've heard of. It turns into a mini 15-year-reunion with no awkward DM required.
The "today days old" angle on this one is that describing-a-person search is genuinely new in a way keyword search never quite got there. If you've ever typed "that guy who had a blog about Postgres query optimization and later worked at Stripe" into Google and given up, Lessie is the answer. The AI actually knows what you mean and goes to get it for you.
Caveats: it's powerful, which means it's the kind of tool that rewards using it thoughtfully. Don't blast 500 cold emails on day one. Start with "who am I trying to reach and why?" and use Lessie as the research accelerator, not the sledgehammer. And expect the occasional server error — it's a young tool.
