13 Best Investor Databases for Startups (2026)

You can get a list of 200,000 investors for $59 a month. That has never been the hard part. The hard part is that you have time for about 40 real conversations, and nothing in a filtered spreadsheet tells you which 40 to spend them on.

This page compares the 13 products founders actually use to find and reach investors, on the four things that change the outcome of a raise: how they narrow the list, whether they explain their picks, how they get you to a human, and what they charge. Brouky is one of them, so read our own rows with that in mind. Everything else comes from vendor pricing and product pages checked on 2026-07-19.

The quick answer

Start free. Use Signal by NFX to find who in your network can introduce you to a specific partner, and OpenVC for a large filterable list with deck-open tracking. Add a ranked matcher when the free lists stop telling you who to prioritise: Raise Copilot is free in beta, Flowlie scores 40+ criteria, and Brouky ranks across 36,000+ investors with the reasoning shown. Use Foundersuite if the pipeline itself is your bottleneck.

What actually separates these products

Ignore the coverage numbers on the homepages. Four differences change how a raise goes.

Free tiers, and where they stop

Four of these cost nothing to start, and the free tiers are good enough that paying early is usually a mistake.

The intro problem

Cold outreach converts badly and every founder knows it, which is why intro paths became the feature everyone advertises. Two different products hide behind the same phrase.

Signal by NFX, OpenVC’s Intro Finder and Flowlie’s mapping all read your network: Gmail, LinkedIn, your inbox. If you went to Stanford and worked at Stripe, these are excellent. If you are raising a first round in Prague or Lisbon with no venture-backed colleagues, they return very little, and the gap has nothing to do with your company.

A graph built from public co-investment history behaves the opposite way. Brouky derives paths from co-investment records, team rosters and founders’ investor lists, so it can route through firms you have never met. Both are worth using. Only one of them works on day one for a founder with no network.

Above $99 a month you are buying a service

Three products in this table break the founder price ceiling, and none of them is selling software at that price. Angels Partners runs your outreach for $599 to $999. Flowlie’s Quill retainer starts at $7,500 a month for a seed-stage company and reaches $15,000 at Series B, which buys a back office rather than a database. Visible’s investor product sits near $449 a month and sells to funds, not founders.

If you are paying more than $99 a month for a list of investors, check what the extra buys. Sometimes a managed service is the right call when you have no time. It is not a better database.

Which to pick

First-time founder, no network, pre-seed

Signal returns little for you, which is the whole problem. Start with a ranked list that does not depend on who you know, then use OpenVC’s free tier to run the outreach. Our guide to finding investors covers the sequence.

Second-time founder, strong network

Signal by NFX first, every time. Your existing graph is the asset, and it costs nothing to mine it. Add a matcher for the funds nobody in your network reaches.

Raising in Europe or CEE

US-built databases thin out fast outside the US and UK. Brouky covers 130+ countries and holds Czech statutory filings from the public registry. Country pages show the coverage per market before you commit to anything.

Pipeline is the bottleneck

Foundersuite. It is the most complete fundraising CRM in this set, with updates, documents and follow-ups, at $745 to $1,609 a year.

You have a deck and 20 minutes

Raise Copilot is free in beta, scores the deck slide by slide and returns 30 to 50 explained matches. Small universe, fast answer.

Where Brouky fits

Brouky ranks investors for a specific startup across 36,000+ investors and shows the reasoning behind each one, using 100,000+ recorded funding rounds and 230K+ investor-to-deal relationships. Two things here are unusual: intro paths come from a pre-built co-investment graph rather than your inbox, and stage matching uses entry-cheque inference rather than raw participation counts.

The honest gap: Brouky has no automated multi-touch follow-up sequences and no deck-open tracking. OpenVC does both, and some founders run it alongside for exactly that reason. Our head-to-head with OpenVC goes through the trade in detail.

Investor rather than founder? The investor-side comparison covers PitchBook, Dealroom, Harmonic and Affinity. The full landscape puts all 24 products in one matrix.

Method

Prices and capabilities come from vendor product pages, pricing pages and third-party reviews, collected on 2026-07-19. Estimated figures are marked. Vendors change pricing without notice, and several of these have conflicting tier structures in circulation. Tell us if something here is wrong.
