Quick profile

Investment thesis

I back the next generation of crypto-native companies that go from 0 to 1 — protocols, infrastructure, and consumer apps that need a 10-year horizon.

Communication style

Direct, founder-first, optimistic about the space, sharp on token design.

Red flags
Founders who treat crypto as a marketing layer rather than a core primitive
No defensibility beyond a single feature
Signature questions
1.What does this look like at 10x the current user count?
2.What's the regulatory path and worst-case outcome?
3.Why is this team uniquely positioned to win this?

How to win Arianna Simpson

AI prep brief from persona data + real pitch history , open for tactics

What convinces them

Crypto must be the core product, not a bolt-on. She backs companies where the token, protocol, or chain is the reason the thing works at all.

She thinks in 10-year cycles. She wants businesses that survive bear markets because the underlying primitive is necessary, not trendy.

Defensibility comes from network effects, liquidity, or protocol lock-in, not a feature. If a fork or a bigger team can copy you in a quarter, you are not building what she funds.

She bets on the team as much as the idea. She needs to believe you have unique insight or access that others don't.

What will kill the pitch

Saying "we use blockchain for transparency" without explaining why that changes the economics. Instead: name the specific cost or trust friction that only a decentralized ledger removes.

Showing a single-use case with no path to compounding. Instead: show how each user or node makes the network more valuable to the next.

Ignoring regulation. She will ask. If you have not mapped the worst case, you look naive. Instead: state the regulatory risk and your mitigation plan clearly.

Claiming a moat that is just "we are first." Instead: show the switching cost or the data/network effect that accumulates.

Questions to prepare

1. What does this look like at 10x the current user count? Walk me through the bottlenecks. 2. What is the regulatory path, and what is the worst-case outcome for this business? 3. Why is this team uniquely positioned to win this, and who else is trying? 4. If a major exchange or protocol copied your core feature tomorrow, what do you still have that they cannot take? 5. What breaks in your token design at scale, and how do you fix it? 6. What have you changed your mind about in the last six months based on user behavior?

How to talk to them

Be direct and technical. She is optimistic about the space but sharp on mechanics, so skip the mission talk and get into design tradeoffs. Do not overhype; she is patient and will wait for substance.

What to lead with at your stage

At SEED, lead with early signals: who is on your waitlist, what pilots are live, and what retention looks like even if small. Then show the 10-year vision and why this primitive becomes more essential over time. Close with your specific edge: what you know or can access that a generalist team cannot.

The bar

A PASS requires proof that the crypto mechanism is load-bearing and that you have a credible path to network effects that compound over a decade. A single clever feature or a hot narrative will not clear it.
