He worked out of a police department for free for a year—then built a $6.8B company. | Ben Rudolph, Co-Founder of Peregrine
27/07/2026 | 42 mins.Ben and his co-founder had no product, no law enforcement background, and no pitch—just an offer to help detectives solve cases. One commander took a chance, handed them background checks, and said "let's see what you can do." They worked out of that police department every day for 18 months. Peregrine just raised $250M at a $6.8B valuation.
In this episode, Ben breaks down how researching every police captain in the Bay Area landed their first design partner, why working as free crime analysts for 18 months was "the purest form of method acting," how forward-deployed engineers drove them from $1M to $3M to $10M ARR, and the 120% RFP prep that won a contract written for a billion-dollar competitor.
Why You Should Listen
Why doing your customer's job is the fastest path to product market fit.
How two founders with no product convinced a police department to let them in.
Why over-investing in deployment became a growth engine, not a margin problem.
How obsessive research wins enterprise deals when you have zero credibility.

Send me a message to let me know what you think!He tries 1,000 ideas a decade & kills nearly all—that's how X built Waymo & Google Brain. | Astro Teller, CEO of Moonshots at X (Alphabet)
13/07/2026 | 48 mins.Astro has run X, Alphabet's Moonshot Factory, for 16 years. His teams created Waymo, Wing, and Google Brain—by testing over 1,000 ideas a decade and killing nearly all of them. His whole system rests on one uncomfortable rule: celebrate the people who kill their own projects.
In this episode, Astro breaks down why you should do the hard thing first, how pre-written kill criteria force intellectual honesty, and why X maximizes learning per dollar instead of progress—and never tracks whose idea it was.

Why working on the riskiest part first is the key to testing new ideas
How writing kill criteria a year in advance stops you from running a zombie startup.
Why progress doesn't matter when launching a new startup.

Send me a message to let me know what you think!He raised $75M—but kept his team to 21 people & pays everyone the same salary. | Cos Nicolaescu, Co-Founder of Accrual
06/07/2026 | 57 mins.Cos was the CTO of Brex, which he helped scale from 40 people to over 1,000. Before that, he led engineering at Stripe. When he finally left, he had no startup idea—just a co-founder he trusted and one rule: whatever they built had to have massive impact. Six months of brainstorming later, they landed on accounting.
In this episode, Cos breaks down why he capped the company at 21 people after raising $75M, why everyone—engineers and salespeople alike—earns the exact same salary, how he hit a 100% pilot-to-production conversion rate with top accounting firms, and the counterintuitive process he used to pick accounting over every other industry.
Why You Should Listen
Why the only reason to join an early-stage company should be the equity, never the cash.
How Accrual hit a 100% pilot-to-production conversion rate selling to the largest accounting firms.

In this episode, Anurag breaks down how he hit $10M ARR in 4 years with zero marketing spend, why refusing to launch a free tier was his most expensive mistake, and how putting engineers on customer support rotations quietly shaped the entire product roadmap.
