The Best Investor Databases for Founders in 2026
Last updated: August 2026
If you're raising money, you've probably already discovered that "investor list" means very different things depending on where you look. Some are free and enormous, some are expensive and built for institutions, and some are somewhere in between. Here's an honest rundown of the main options, including where each one genuinely shines and where it falls short.
Signal by NFX
FreeA well-known free tool from NFX, built on their own investor network. Strong for filtering by stage, sector, and check size, with a genuinely large pool of contacts.
Strengths
- Completely free
- Large, filterable network
- Backed by a known VC brand
Limitations
- Contact depth varies by investor
- No downloadable export, browser-based only
OpenVC
FreeA community-maintained, crowdsourced investor database. Breadth is a real strength here, since anyone can contribute profiles.
Strengths
- Free and very large
- Community-contributed, frequently added to
Limitations
- Data quality is inconsistent, since anyone can submit
- Less curation than a maintained dataset
vcsheet.com
FreeA well-regarded spreadsheet of early-stage investors and funds, put together by a small group of operators. Good starting point for pre-seed and seed founders specifically.
Strengths
- Free and genuinely useful for early stage
- Simple, no-frills format
Limitations
- Narrower stage focus
- Static, not on a refresh cycle
Crunchbase Pro
Paid, subscriptionBroad company and funding data with investor profiles layered in. Better known as a general business database than an investor-specific tool.
Strengths
- Huge underlying company/funding dataset
- Well-established, widely trusted
Limitations
- Monthly subscription, not a one-off cost
- Investor detail is broader than deep
PitchBook
Paid, enterpriseThe industry standard tool, but genuinely built for institutional users like VCs and bankers, priced and packaged accordingly.
Strengths
- Extremely comprehensive
- Trusted throughout the industry
Limitations
- Enterprise pricing, generally out of reach for individual founders
- Built for institutional workflows, not a quick founder lookup
The Capital Register
One time payment, $129Our own dataset, covering 10,000+ investors worldwide, with fund thesis, cheque size, sector focus, and named contacts where publicly available or opted in. Refreshed quarterly, delivered as a clean spreadsheet.
Strengths
- One time cost, not a subscription
- Own the file, works offline, in your own CRM
- Quarterly refresh, not a static export
Limitations
- Not free, unlike several options above
- Not every profile includes a direct personal contact
Which one is actually right for you?
If your budget is genuinely zero, start with Signal or vcsheet.com. Both are free and useful, especially at pre-seed. If you want breadth and don't mind inconsistent data quality, OpenVC is worth a look. If you're at a company already paying for Crunchbase or PitchBook for other reasons, their investor data is a reasonable bonus rather than a primary reason to subscribe.
If you'd rather own a clean, structured file you can filter and reuse without a subscription clock running, that's specifically what The Capital Register is built for.
