There is no register of angel investors. An angel is a person, not an institution, and the record of what they back sits in filings, syndicate pages and their own posts. Causo reads those one by one.
Reviewed August 2026
Three hundred and sixty-seven thousand people, and no list of who they are. A fund publishes a thesis, a team page and a portfolio. An angel publishes nothing, and is under no obligation to. What exists is the trace they leave elsewhere.
You upload your deck. Causo reads it, then reads the record every angel has left behind, and comes back with the individuals who have actually written cheques into companies like yours — each with the reasoning behind the score.
Two threads that meet on one idea: applied AI aimed at sustainability and decarbonisation, and alternative ownership — cooperatives, employee ownership, community network effects. More than thirty angel positions taken in the ownership economy before most of the capital moved into a pre-seed firm he co-founded in 2022, and both threads are still visible in the portfolio.
A real profile from the catalogue with the identity removed. The thesis, stage, sectors, portfolio and cited sources are exactly as Causo holds them.
An angel publishes no thesis page and no portfolio, so the profile is assembled rather than copied. This is a live row from the catalogue with the identity removed — every field is read from a named source, and where a figure cannot be trusted the profile says so.
| Individual angel | Syndicate | Family office | |
|---|---|---|---|
| Who decides | One person, alone | The lead; members follow | Staff, against a mandate |
| Speed | Days | Days for the lead, weeks to fill | Weeks |
| Typical cheque | Smallest | Assembled from many | Largest of the three |
| What convinces them | You, and their own sector experience | The lead, then the deal | Fit with the mandate |
| Where they are listed | Nowhere | Syndicate platforms only | Rarely, and not as funds |
| Who to approach | Them | The lead, never the members | The investment staff |
There is no register of angel investors to search, so finding them means reading the record they leave behind: filings that name shareholders, syndicate pages, funding announcements, and their own accounts of what they have backed. Causo reads those sources and returns individuals who have invested in companies like yours, with the evidence attached to each one.
No. Angels are usually more reachable than funds, because you are contacting a person directly rather than a firm with a screening process. A warm introduction helps, but a specific cold email that names why this particular angel is relevant to your company works regularly. What does not work is a generic message sent at volume.
An angel invests their own money and decides alone, usually in smaller amounts and much faster. A VC fund invests other people’s money under a mandate, with partners, an investment committee and a fund cycle that shapes when it can deploy. Angels typically come earlier, and often before a fund will look at you at all.
A syndicate is a lead angel plus a membership who invest alongside them. The lead does the diligence and sets the terms, and the members follow with smaller amounts. For a founder this means the whole task is convincing the lead, since the rest of the cheque assembles behind that decision.
Not exactly, though they often invest at the same stage. A family office has professional staff, a mandate and a process, so it decides more like a fund than like an individual. It is worth treating as its own category, which is why Causo separates the three rather than lumping them together.
It varies far more than with funds, because there is no fund size setting the range. Individual angels commonly write smaller cheques than institutions, syndicates assemble larger ones from many members, and family offices can go considerably higher. The useful question is not the typical amount but what a specific angel has actually written before.
