Belsky's angel-investing filter splits into team and product. On team he wants founders driven by mission over money, who listen and learn, and who are optimistic about the future but pragmatic and even pessimistic about the present, while he has an allergic reaction to slick promoters who sugarcoat the truth. On product he wants a scalable object model (how did I get here, what do I do now, what next) and genuine belief in the problem being solved.
Origin
Scott Belsky's personal angel-investing criteria, drawn from backing companies like Pinterest, Uber, and Airtable and from his experience as a founder himself.
Core principles
- 01Team first: mission over money, because pre-revenue survival needs a motivation grander than revenue.
- 02Back founders who listen and long to learn.
- 03Favor optimism about the future paired with pragmatic pessimism about the present.
- 04Have an allergic reaction to promoters who gloss over the hard parts.
- 05Product must have a clear, scalable object model and a problem you genuinely believe in.
How to run it
- 1
Screen the founder's motivation
Check whether they value the mission more than the money it yields, since that is what sustains them through the pre-revenue period.
Pro tip Look for people who long to learn and genuinely listen.
Watch out Founders motivated primarily by money tend to lack fuel during the long unpaid middle.
- 2
Test present-tense honesty
Prefer founders who are optimistic about the future but pragmatic and somewhat pessimistic about the present, naming the obstacles, missing data sets, and things that keep them up at night.
Pro tip Good chemistry sounds like 'the market is huge and this needs to exist, but here's everything not working yet.'
Watch out Be wary of name-dropping, over-promoting founders who sugarcoat the truth; they can't partner honestly through the messy middle.
- 3
Assess the product's object model and problem
Confirm the product has a clear, scalable object model (how did I get here, what do I do now, what next) and that you believe in the problem being solved.
Pro tip A muddled, 'all over the place' demo signals the team doesn't value funnel clarity and is a red flag.
Watch out Skip products where you don't actually believe in the underlying problem, however strong the team.
In the wild
Belsky describes the founders he has chemistry with as people who say this is how big the market is and I know this needs to exist, but we have a lot to figure out, these data sets are missing, and these are the obstacles that keep me up at night.
→ He trusts those founders to give investors and teams the real truth during the volatile middle so problems get solved.
Common mistakes
Backing the slick promoter
Founders who constantly sugarcoat and gloss over the hard parts can't be honest partners when the messy middle hits, leaving investors and teams without the real truth needed to find solutions.
Funding a team whose product has no clear object model
A demo that's 'all over the place' with no clean breadcrumbs signals the team doesn't value moving users through the funnel, which undermines the whole bet regardless of the pitch.
Is it for you?
Best for
Angel investors and early-stage backers evaluating pre-revenue, product-and-design-oriented founding teams.
Not ideal for
Later-stage or metrics-driven investments where traction and financials, not founder chemistry, dominate the decision.
From the transcript
“I really value founders who ... value the mission that they're on more than the money that it yields”
“I've always admired leaders that are optimistic about the future but very pragmatic and somewhat pessimistic about the present.”
“I also have an allergic reaction to founders that are real promoters, you know, who are constantly trying to sugarcoat the truth”
“I am looking for an object model way of thinking about a product that I'm confident that that will will will scale”
