Any stage, any thesis

How to find active investors and their contact information.

Lessie helps you find active investors — the funds and angels actually deploying capital in your stage, sector and geo — with partner-direct contacts and a signal-based personalized opener, not a static VC directory.

Why signals

A long investor list is not the same as a warm one.

Most investors on a static list are not deploying in your space this quarter. The ones who just raised a fund, made a recent check in your category, or publicly posted their thesis are far more likely to be relevant — so those are the ones to reach first.

Signal 01 · Public posts

Investors say what they want to fund — out loud

“My DMs are open for devtools founders.” “Bullish on vertical AI.” “Send me deals with traction.” Lessie reads the thesis underneath.

  • X, LinkedIn, podcasts, Substack + founder communities
  • Messy language understood — any language

Signal 02 · Fund & deal events

A fresh fund is a deployment clock

A new fund close. A first check in your category. A new partner. Lessie maps each event to the investor most likely to be deploying.

  • New fund closes & first closes — dry powder with a clock
  • In-category deals & new partners — already convinced
  • Filtered to your stage, sector & geo

From signal to sent

How does signal-based investor search work?

The moment a signal lands — a fund close, a thesis tweet, an in-category deal — Lessie runs the play: finds the partner, verifies the contact, and writes an opener that quotes their own words.

No cold lists. No spray-and-pray. You reach out with a relevant, specific reason.

FAQ

How to find active investors — questions founders ask

What are “investor signals” and how do they help me find active investors?

Investor signals are real-time indicators that an investor is actively deploying capital — a fund that just closed, a partner publicly discussing your space, a recent check in your category. Instead of a static list of every investor, signals surface who is most likely to invest now, so you can reach the right people first.

How do I find active investors who are backing startups like mine?

Describe who you are looking for in plain language — stage, sector, geography, check size. Lessie searches across structured databases and the open web, reviews each candidate for fit and recent activity, and returns a short list of active investors with contact details you can reach out to in the same workflow.

How is signal-based investor search different from a database like Crunchbase or PitchBook?

Databases list investors and let you filter; they do not tell you who is deploying right now, and personal contact data is often limited. A signal-based approach prioritizes investors showing recent, relevant activity and pairs them with outreach — so you spend time on the funds most likely to respond, not the whole directory.

Are the investor contacts accurate and safe to use?

Contact details are pulled from live sources at search time and each candidate is reviewed for fit, so you start from current, relevant people rather than a stale export. Always verify an address before a large send and follow normal outreach etiquette — personalize, and do not blast.

How much does it cost?

Lessie is credit-based. Plans start at $99/mo (Basic, 1,000 credits/mo), with Pro at $299/mo (4,000 credits) and Max at $699/mo (10,000 credits). You are charged based on the actions you take. See the pricing page for current details.

How do I find seed investors for my sector, like AI or fintech?

Describe the thesis you fit — for example “seed investors backing AI infrastructure in the US, check size $250K–$1M” — and Lessie returns a fit-reviewed short list of investors active in that space, with contacts and outreach, rather than a generic VC directory to scroll.

Somewhere, a partner just posted your thesis.

Describe your round once — stage, sector, geo. Wake up to investors actively deploying, with partner-direct contacts and a signal-based personalized opener.
