    He worked out of a police department for free for a year—then built a $6.8B company. | Ben Rudolph, Co-Founder of Peregrine

    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.Keywords startup podcast, startup podcast for founders, product market fit, finding pmf, Peregrine, govtech, public safety technology, forward deployed engineers, selling to government, enterprise sales, data integration, design partners, Ben Rudolph Chapters 00:00:00 Intro00:01:07 The Moment of True Product Market Fit00:11:51 Getting a Police Department to Say Yes00:16:45 Slow Growth and Word of Mouth00:19:49 Forward-Deployed Engineers Before They Were Cool00:27:34 Cracking Government Go-To-Market00:34:08 Winning an RFP Written for Someone ElseSend me a message to let me know what you think!

    Damien left his job to start a startup solo. Two years later, Nebulock closed a $25M Series A. In between: 90 customer interviews in 90 days, a year of design partners, and a Fortune 500 deal that closed in 6 weeks. In this episode, Damien breaks down how his 90-in-90 customer discovery sprint killed his original architecture before he wasted money building it, how his design partner program converted 100% into paying customers, and how a POC playbook needing just 2 hours of customer time closed a Fortune 500 in 6 weeks.

    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)

    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 You Should Listen Why working on the riskiest part first is the key to testing new ideasHow writing kill criteria a year in advance stops you from running a zombie startup.Why progress doesn't matter when launching a new startup.How to come up with big ideas like Waymo and Wing.Keywords startup podcast, startup podcast for founders, product market fit, finding pmf, Astro Teller, Google X, moonshot factory, Alphabet, Waymo, innovation process, kill criteria, idea validation, deep tech Chapters 00:00:00 Intro00:04:15 Inside Alphabet's Moonshot Factory00:07:22 The Card Counters of Innovation00:14:00 Learning per Dollar, Not Progress00:23:04 Killing Ideas with Testable Hypotheses00:26:34 Train the Monkey First00:35:16 Kill Criteria: A Message to Your Future Self00:41:59 The Moment of True Product Market FitSend 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

    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.Why he raised $75M but refuses to grow past 21 people.How to tell real product market fit from the "just one more feature" trap.Keywords startup podcast, startup podcast for founders, product market fit, finding pmf, AI accounting, vertical AI, enterprise sales, pilot to production, Brex, Stripe, Cosmin Nicolaescu, Accrual, lean team Chapters 00:00:00 Intro00:01:56 The Moment of True Product Market Fit00:09:46 Collapsing 6+ Tools Into One Platform00:18:07 Leaving Brex to Start From Scratch00:31:41 Landing H&R Block and Armanino00:34:57 A 100% Pilot-to-Production Playbook00:43:26 A 21-Person Company by Design00:51:38 One Salary for EveryoneSend me a message to let me know what you think!

    He quit Stripe and hit $10M ARR in 4 years—with $0 marketing spend. | Anurag Goel, Founder of Render

    Anurag was employee #8 at Stripe, set for life and free to do anything next. Instead he spent a year and a half hunting for a problem worth decades of his life. He chose to build a product to make it simple for developers to ship apps, going head-to-head with AWS. 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. Why You Should Listen Why you don't have real product market fit until your users sell the product for you.How a sub-2-minute setup turned developers into a word-of-mouth machine.Why skipping a free tier for years was his most expensive mistake.How engineers doing support on rotation built the roadmap—and 6M+ developers.Keywords startup podcast, startup podcast for founders, product market fit, finding pmf, developer tools, cloud infrastructure, PaaS, Render, word of mouth growth, product-led growth, AI infrastructure, Stripe Chapters 00:00:00 Intro00:01:44 The Moment of True Product Market Fit00:04:14 The #1 Driver of Word of Mouth00:13:25 Why He Left Stripe to Build Render00:23:48 Why AWS Would Never Build This00:30:33 $10M ARR With No Marketing Spend00:36:43 Engineers as the Support Team00:42:19 Riding the AI BoomSend me a message to let me know what you think!

    He shut down his last startup and gave the money back—then hit $1M ARR in 6 months. | George, Founder of Monk

    George had to wind down his last startup and give investors their money back. He went deep into the valley of despair, certain he'd missed his window to build something big. Then he met a co-founder, decided to start over, and started selling. In this episode, George breaks down how a customer signed a $36K pilot off nothing but a Loom and a one-pager, how cold email took him from zero to $1M ARR with no sales team, and why a "seven out of ten" is the most dangerous hire you can make. Why You Should Listen How a customer signed a $36K pilot after a single Loom and zero calls.Why he gave the money back on his last startup—and what "follow your energy" really means.How cold outbound email built his first $1M ARR with no sales team.Why a "seven out of ten" is the most dangerous hire you can make.Keywords startup podcast, startup podcast for founders, product market fit, finding pmf, fintech, accounts receivable automation, AI agents, cold outbound email, B2B SaaS, Series A fundraising, services as software Chapters 00:00:00 Intro00:01:39 The Moment of True Product Market Fit00:03:33 Shutting Down a Small-Market Startup00:07:44 Picking Fintech From Five Ideas00:17:12 From Black Box to Full App00:24:47 $1M ARR on Cold Email Alone00:36:11 Why a "Seven" Is the Most Dangerous Hire00:42:15 Compressing a $25M Series ASend me a message to let me know what you think!

    He quit his $50M ARR startup to work as a paralegal—then raised a $60M Series A. | Dan Mishin, Founder of Manifest

    Dan founded and scaled a $50M ARR, SoftBank-backed startup—and could've stayed to make tens of millions. Instead, he handed it to his chief of staff and started from scratch. He wanted something bigger. He took an entry-level paralegal job to learn everything about law hands on. Then he built Manifest, which just raised a $60M Series A. In this episode, Dan breaks down why he did intake calls for 1,000 legal clients before building anything, how free Slack communities turned Fortune 500 HR managers into buyers without a dollar of ads, and why he refused to sell software to law firms even when investors told him he was crazy.

    He churned 100% of his revenue on purpose—then grew 10x to $2M ARR in under 12 months. | Ali Khokhar, Founder of Amigo AI

    Ali quit his job a few months after ChatGPT launched, convinced AI would eat labor marketplaces like Upwork. With no co-founder and no code, he collected $12K from real customers—using a faked demo and a cloned voice. Then he pitched 100 VCs in 10 days and got 47 straight 'no's. In this episode, Ali breaks down how he banked $12K in revenue before writing a single line of code, how a $20/month Slack community drove Amigo's first $1M in ARR, and why he churned every existing customer to go all-in on $100K+ healthcare enterprise deals.
