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.

Why You Should Listen

• How 90 customer interviews in 90 days saved him from building the wrong product.
• Why every single design partner converted into a paying customer.
• How a 2-hour POC playbook closed a Fortune 500 in just 6 weeks.
• Why procurement—not your champion—decides how fast your deal closes.

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 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.
• How to come up with big ideas like Waymo and Wing.

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.

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.

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 he gave the money back on his last startup—and what "follow your energy" really means.

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.

Why You Should Listen

• How 2 months working as a paralegal beat years of customer discovery.
• How free Slack communities turned Fortune 500 HR managers into clients.
• Why earned media compounds like an asset while paid ads burn like an expense.
• Why impact is the best driver for starting startups.

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.

Why You Should Listen

• Why validation only counts when dollars exchange hands.
• How a $20/month paid community turned into $1M in ARR.
• Why he refunded every customer and churned 100% of his revenue.
• Why founders must sell the first $2M themselves before hiring an AE.

Mark was running a startup out of a tiny annex office in Dublin with zero product usage. Then one customer turned it on and overnight he saw usage spike to thousands of simulations. He got to $1M ARR 100% through outbound, by sending 500,000 cold emails. A few months ago he closed a $25M Series A.

In this episode, Mark breaks down the pivot from sales roleplay to customer support that unlocked his first real traction, the cold outbound playbook that took him to $1M ARR (500K emails, 250 meetings, 40 customers), and why doorstepping customers in Utah is what drove his net revenue retention to 186%.

Why You Should Listen

• Exactly how to use a cold outbound strategy to hit $1M ARR.
• Why getting on 56 flights last year to visit customers led to 186% NRR.
• How he closed a $25M Series A in just 6 days.
