About Me

Builder First, Investor Second.

I'm Berk Ozer. I've been on both sides of the table — as a 2x founder and venture lead. Previously I co-founded SenpAI (YC S21), a real-time AI gaming coach. I shipped "ChatGPT for gamers" in 2019, three years before the LLM wave hit the mainstream. I scaled the product to 500K monthly active users with near-zero ad spend. As a venture lead, I invested in 150 startups, helped portfolio companies with product, GTM, and fundraising, leading to $100M+ in follow-on funding. Based in SF. Currently building something new.

How I Help

Fundraising

Raised $3M+ as a founder. Helped 100+ founders raise $100M+ as a VC. I know what works on both sides of the table.

Go-to-Market

Scaled SenpAI to 500K users with near-zero ad spend. Built GTM playbooks driving 5,000+ applications annually at Orange DAO. B2C and B2B.

Product

I ship. Been building AI products since 2017 — before the hype. From prototypes to production, I build alongside founders.

Angel Investments

What Makes Me Write Checks

I invest in AI-native companies at pre-seed and seed.

The Golden Era

AI will reshape every industry in the next five years. Founders building now are in the golden era.

Earned Secrets

Insights earned from real customer conversations, not market reports. Show me what you learned that no one else knows.

Relentless Resourcefulness

Builders who find a way when there is no way. I back founders who figure it out.

Conviction Over Consensus

I don't wait for other investors to validate. I back founders others overlook.
