About

Builder first, investor second.

I'm Berk Ozer. I've spent most of my career building products, and some of it backing people who build them. Previously I co-founded SenpAI (YC S21), a real-time AI gaming coach. We shipped "ChatGPT for gamers" in 2019, three years before the LLM wave hit the mainstream, and scaled it to 500K monthly active users with near-zero ad spend. At Orange DAO, I invested in 150 startups and worked closely with founders on product, distribution, and fundraising. The portfolio went on to raise $100M+ in follow-on funding. Based in SF. Currently building something new.

How I Help

A few places I help founders.

01

Fundraising

I’ve raised millions from VCs as a founder and invested in hundreds of startups. I help founders tighten what actually gets meetings and term sheets: narrative, blurb, investor memo, warm intros, objections, and the fundraising sprint.

02

Distribution

I’ve built consumer growth loops and investor networks from zero. I help founders move from launches into repeatable motion: who to reach first, what channel to bet on, what message gets a response, and what loop keeps working after the first spike.

03

Product

I’ve built AI products from prototype to millions of users, and learned the hard way that usage is not the same as urgency. I help founders sharpen the wedge, find the real customer, and cut what makes the product harder to understand.

Angel Investments

I write angel checks into pre-seed and seed-stage companies.

I look for earned secrets from talking to customers and living inside the problem. I back resourceful founders with non-obvious ideas before everyone else agrees.
