What Is an Investor Database?
An investor database is a searchable list of investors, funds, and accelerators, usually with contact details and filters for stage, sector, and geography. A big row count on its own means nothing if the emails are dead and the funds stopped writing checks years ago. What actually makes a database useful is whether it stays current, whether the contacts still work, and whether you can send and track outreach from the same place, which is exactly what the Round Funded investor database is built around.
Most founders find this out the hard way. They pull a list with tens of thousands of names, send 40 emails, and a good chunk bounce because the fund closed or the partner moved on years ago. A big number on a homepage tells you nothing about how current the list underneath it actually is.
Why Most Investor Databases Don't Get You a Reply
- Size is a vanity metric. A database with 200,000 rows and one with 20,000 rows produce the same number of usable contacts if half of the bigger one is stale.
- "Investor" often means dead weight. Plenty of lists still include funds that stopped deploying, partners who left, and firms that quietly pivoted to a later stage.
- Contacts bounce and nobody warns you. Most raw databases sell you an email address with no promise that it still works. You find out when the bounce hits your own sender reputation.
- Finding and reaching are treated as separate jobs. You get names in one tool, draft in Gmail, and track replies in a spreadsheet, and none of it talks to the others.
None of this means databases are useless. It means the number on the homepage is the wrong thing to compare first.
The 4 Things That Actually Make an Investor Database Useful
Size, but Only After Filtering
A raw number like 10,000 or 200,000 tells you almost nothing until you know how many of those rows are current. A smaller, filtered database of active investors beats a larger one padded with dead entries every time you actually send an email.
Active Filtering: Did They Write a Check Recently
The strongest signal that an investor is worth emailing is recency. Round Funded filters its database to investors who made a check in roughly the last six months, the standard a database should be held to, even though most raw lists never publish this filter at all.
Verified, Deliverable Emails
A database is only as good as the emails inside it. Round Funded runs every contact through automated deliverability verification and hides addresses that bounce or cannot be confirmed, rather than showing them as if they still work. Most raw scraped lists make no such promise, so a dead email looks identical to a live one until you send to it.
Can You Reach Out From the Same Tool
A database that only hands you names still leaves you exporting to a spreadsheet, drafting in Gmail, and tracking replies by hand. The databases worth paying for in 2026 combine the list with real outreach and tracking, so a reply lands in the same place you found the contact.
Investor Database Tools Compared
| Database | Size | Active filter | Verified emails | Reach out from the same tool | Price |
|---|---|---|---|---|---|
| Round Funded | 60,000+ active investors, angels, VCs, accelerators, incubators | Yes, filtered by investors who invested recently | Yes, every contact is deliverability-checked before it shows up | Yes, AI-drafted outreach from your own Gmail, plus CRM tracking | Round+ $99/mo, Pro $249/mo, Lifetime $899, no free tier |
| Crunchbase | Very large company and funding database | No, built for research, not recency | No, not a contact-verification product | No | Pro from roughly $49/mo |
| OpenVC | Free, opt-in investor directory | Partial, investors self-list | Not explicitly verified, but opt-in reduces dead entries | Yes, via a moderated submit-deck gateway | Free tier, paid plan around $99/mo lifts limits |
| AngelList | Investor network via syndicates and SAFEs | No, not a searchable contact database | Not applicable | No, it is an investing rail, not outreach | Free, takes fees on deals |
| Foundersuite | Very large investor database, since roughly 2014 | Not the headline feature | Not the headline feature | Yes, basic, from your own inbox | Paid, roughly $44 to $144/mo |
| PitchBook | Comprehensive institutional data terminal | Deep, at institutional scope | Not built for founder outreach | No | Roughly $25k+ a seat, per year |
Worth knowing about as a free option: Signal, NFX's free VC search tool, is a reasonable first pass at who invests in your category, though it has no active filter, no verified emails, and no outreach layer of its own.
Round Funded
Round Funded is built on one idea: a database only matters if it stays current and you can act on it without leaving the tool. The 60,000+ active investors are filtered by recent activity, and accelerators and incubators sit alongside angels and funds instead of being an afterthought. Connect your own Gmail and the AI drafts a personalized first email from your real startup profile, sends it, and tracks opens and replies. It runs in 12 languages, which matters for founders raising outside the US.
There is no free tier: it is $99/mo for Round+, $249/mo for Round Pro, or $899 once for Lifetime, with a 3-day trial for first-time subscribers. That is a deliberate filter for founders actually running a raise, not a reason to browse for free.

Crunchbase
Crunchbase is genuinely excellent at what it is built for: researching a company's funding history, its investors, and its competitors. It was never designed to hand you a verified, deliverable investor email, and it makes no claim about which of its investor entries are still active.
OpenVC
OpenVC's free directory and its "submit deck" gateway (your deck goes through moderation and forwards from a whitelisted address) genuinely improve reply rates for the opt-in investors on the other end. The trade-off is a moderation queue, roughly one outreach a day on the free tier, and English-only coverage.
AngelList
AngelList is not really a database you search to discover new investors. It is an investing rail, syndicates, rolling funds, SAFEs, built for closing a round with people you already have lined up, not for finding who to pitch next.
Foundersuite
Foundersuite has a genuinely large investor database wrapped in a mature CRM with deck hosting, investor updates, and a data room. It is a solid all-in-one option if an older interface and English-only coverage do not bother you.
PitchBook
PitchBook is a comprehensive, institutional-grade data terminal, priced for private equity firms and investment banks, not a founder deciding who to email this week: roughly $25,000 or more per seat, per year. It is worth knowing exists, and worth skipping at the pre-seed or seed stage.
Where Round Funded Fits
Most of the tools above solve one piece of the problem: a list, a research tool, or an outreach app. Round Funded is built to be the whole loop, so "is this investor active" and "did they open my email" live in the same place instead of three different tabs.
The database covers 60,000+ active investors filtered by recent activity, with accelerators and incubators as full first-class entries. Fill out a structured startup profile once (stage, sector, geography, traction, ask), and the AI drafts a personalized first email grounded in your real data, sends it from your connected Gmail, and tracks opens and replies automatically.

How to Actually Use an Investor Database
- Start with the Round Funded investor database, filtered for activity, not just size. Filter by stage and sector so your list is investors who wrote a check recently, not names scraped from a spreadsheet a year ago.
- Check that the emails are verified before you send. A database that hides or flags dead contacts protects your sender reputation. One that hands you a raw, unverified list will cost you it.
- Include accelerators and incubators in the same search. A real share of pre-seed capital moves through structured programs, and most general investor databases skip them entirely.
- Build a list of 75 to 150 targets before you send a single email. At realistic cold-outreach rates, that volume typically produces the 8 to 12 committed checks a standard round needs.
- Write one specific email, not a template. A 90-word note with a real why-them line and your sharpest traction number outperforms a generic blast sent to a bigger list.
- Send and track from one place. Keep the database, the outreach, and the reply tracking together instead of a spreadsheet plus three browser tabs.
- Follow up twice before moving on. Roughly half of investor replies come from the second or third touch, not the first email.
Frequently Asked Questions
Where can I find a database of active investors and VCs?
Round Funded is built specifically for this: a database of 60,000+ active investors, filtered by who made a check in roughly the last six months, covering angels, VCs, accelerators, and incubators in one search instead of separate lists you have to stitch together.
What is the best investor database for a pre-seed startup?
For pre-seed, the best database includes angels and accelerators alongside funds, since a large share of pre-seed capital moves through programs, not just VC checks. Round Funded treats both as first-class entries and lets you filter down to pre-seed specifically.
Is Crunchbase good for finding investors to email?
Crunchbase is strong for researching a company's funding history and investor list, but it was not built to hand you a verified, deliverable email or to filter for who is still actively investing. It works well as a research step before you move to a database built for outreach.
Is there a free investor database?
Yes. Signal (NFX) and VCSheet are both free and useful for a first pass at names. Neither filters for recent activity or verifies emails, so treat them as a starting point for research, not a list you send real outreach to directly.
How do I know if an investor's contact in a database is still active?
Check whether the database publishes a recency filter, such as "invested in the last six months," instead of trusting a raw size claim on the homepage. Round Funded builds that filter directly into the search rather than leaving founders to guess from an old spreadsheet.
Does Round Funded verify the emails in its investor database?
Yes. Every contact goes through automated deliverability verification before it ships, and addresses that bounce or cannot be confirmed are hidden rather than displayed as if they work. That is different from a raw scraped list, where a dead email looks identical to a live one until you send it.
What's the difference between an investor database and an outreach tool?
A database (Crunchbase, VCSheet, a scraped list) gives you names and contacts to work with by hand. An outreach tool drafts, sends, and tracks the email for you. Round Funded combines both, so you are not exporting a filtered list into a separate cold-email app.
Final Word
The size on a database's homepage is the least useful number on the page. What matters is whether the investors inside it are still active, whether the emails actually land, and whether you can reach out and track the reply without ever leaving the tool.
