HOW TO GET A WARM INTRO TO INVESTORS

I'M 30. I BUILT AN AI STARTUP CALLED GOJIBERRYAI DOING OVER $4M ARR IN ONE YEAR

A founder who took GojiberryAI from nothing to about $3.5M ARR in twelve months, and got into YC, wrote up what he would do from zero. His answer is that reply rates come down to who you send to. He sold with a six-slide deck and made his first $10K before writing code. His customer was painfully specific: founders at 20-person SaaS companies about to hire a first sales rep. Outbound went only to people showing intent, and he puts the reply rate at 25-40% against the usual 1-2%. One channel at a time, priced at $99 a month.

04TOOLS & RESOURCES

AGENT AUTH

Agents need identities and credentials. This usually means handing them a long-lived API key or letting them borrow a user's session. Agent Auth gives agents real identities in AuthKit. Users define blueprints for what an agent is allowed to do, and the agent gets short-lived, tightly scoped tokens every time it runs.

AI PRODUCTIVITY DOESN'T MEAN WHAT I THOUGHT IT MEANS

AI productivity may raise quality rather than reduce human effort. In one writing workflow, editing volume stayed constant while AI lifted the quality floor, suggesting automation lets knowledge workers concentrate on craft and produce better work with the same effort.

THE SERIES A IS DEAD, LONG LIVE THE SERIES A

Series A rounds are growing larger, with median sizes quadrupling over the last decade, pushing many funds out and refocusing investments into pre-seed and seed stages. The market now features fewer Series A investors, leading to less liquidity and an emphasis on companies with extreme growth or ambitious narratives. Small funds struggle as they must adapt to these expectations while focusing on higher concentration strategies and potential exits in the changing landscape.
