Introduction

Most founders get one big break and spend the rest of their careers talking about it. Damon Chen's break came after four consecutive failures — four shipped products that collectively earned about $3,027. His fifth product, Testimonial.to, a tool for collecting customer video testimonials, went from its first dollar in December 2020 to a six-figure annual run rate in nine months, and to a reported $840K in annual recurring revenue within a few years.

Chen is a former Cisco engineer who quit his stable eight-year job during the pandemic, taught himself web development while his newborn napped on his chest, and promised his wife he would go back to employment within a year if he couldn't make $100K annually. He beat that target — and then, by his own public accounting, kept beating it by an order of magnitude. By 2025 his portfolio of small SaaS products was reportedly moving around $1.3 million a year, all bootstrapped, mostly solo.

The Story

Chen's blueprint was the standard-issue immigrant success story: arrive from China, get through Penn State, land a marquee engineering job. He spent eight years at Cisco, where his salary crept from roughly $100K to $150K and every promotion cycle, in his own telling, felt like watching a parade he wasn't invited to. Then 2020 arrived with lockdowns and a newborn, and the calculus changed. He quit — family first, paycheck second.

What followed was a crash course in shipping. Chen enrolled in a web dev bootcamp and YouTube tutorials, learned HTML, CSS, and React from scratch, and started launching. The first four products went nowhere: two earned literally zero revenue, a third made $1.99 total, and a fourth spiked to $3,025 in ten days and then died. That is four failures in roughly a year, with two small children at home.

The fifth product came from a pain Chen had felt himself. Every one of his launches had struggled with the same chore: getting customers to write testimonials. Collecting social proof meant clumsy emails, forms, and back-and-forth follow-ups, and video testimonials were the worst of all. So he built the tool he wished existed — a simple page where businesses could request testimonials and customers could record and submit them in seconds. He launched Testimonial.to in December 2020. On December 23, 2020, the first dollar landed. He has said he couldn't sleep that night.

The numbers after that read like a textbook bootstrapped growth curve. By March 2021 the product was pulling in $1,000 a month. Nine months after launch it crossed a $100K annual run rate. Its first full year closed around $200K in ARR. By April 2022 he was at roughly $13K in monthly recurring revenue; by November 2022, about $30K a month, in an Indie Hackers interview. By late 2023, Testimonial.to was reportedly at approximately $840K in ARR, with customers including Fortune 500 companies and well-known creators like Justin Welsh.

Chen's growth playbook had three unusual ingredients. First, he launched on Product Hunt with lifetime deals — one-time payments that validated demand and generated early cash — then deliberately migrated customers to subscriptions for durable revenue. Second, he practiced open startup: he published Testimonial.to's revenue numbers every month, turning the growth curve itself into a trust asset. Customers could see the product winning in real time, and that transparency converted. Third, he built in public on Twitter, documenting every milestone until his audience became his distribution channel.

The transparency had a cost. By 2022, copycats were mirroring his features and his playbook, so in October 2022 Chen stopped publishing his numbers. Openness had done its job; guarding the edge mattered more now. That same year he reportedly turned down a seven-figure acquisition offer for Testimonial.to — the business, he felt, was too young to sell.

Meanwhile he kept his shipping habit. He built embed.so, a side project, in two and a half days. He launched channel.so. He acquired Supportman, a customer-support tool, from fellow indie hacker Noah Bragg. The portfolio kept compounding: by September 2023 his whole stable was reportedly humming at around $130,000 a month.

Then he rode the biggest wave of the decade. When ChatGPT ignited demand for AI tools in late 2022, Chen bought a weekend project called Looseleaf.ai, rebranded it as PDF.ai — a tool for chatting with PDF documents — and ran his proven playbook again: a $99 lifetime deal to validate monetization, which attracted over 300 adopters in three months, then a shift to subscriptions. PDF.ai reportedly grew beyond $50K in monthly recurring revenue. His total domain investment was modest — under $10K for PDF.ai — but the returns were outsized.

In 2024 he made a move that says everything about his philosophy. Earning over $130,000 a month, he left the San Francisco Bay Area for Shanghai. His line: "I earn in dollars and spend in yuan." Same income, radically lower costs — a geographic arbitrage on top of a business arbitrage. By 2025, the whole portfolio was reportedly moving about $1.3 million a year. In May that year he posted a characteristically honest note: at 40, hitting $1M a year after four years felt slow compared to funded founders sprinting past him. Then he shrugged and kept building. "Craft your life, your way. There are no wrong blueprints."

Lessons

Damon Chen's run offers three mechanics worth stealing:

  1. Give every project a failure budget: Chen's four flops weren't accidents — they were a process. Each project cost him weeks, not years, because he shipped fast and let revenue signals do the killing. The mechanism: before you start a side project, write down a hard budget — a fixed number of weeks and a fixed dollar cap. Ship the smallest version that can take money. If it earns nothing by the deadline, kill it and log what you learned. Most people do the opposite: they spend months polishing one idea and treat killing it as defeat. Chen's portfolio arithmetic only works because the losers were cheap.

  2. Sell lifetime deals first, subscriptions second: Testimonial.to and PDF.ai both started with lifetime deals — one-time payments on Product Hunt that answered the only question that matters ("will anyone pay?") while generating cash to fund the next iteration. Only after demand was proven did Chen migrate to subscriptions for durable revenue. Copy it: for a new product, run a bounded lifetime-deal campaign (a few months, a clear price like $99) to validate monetization and build an initial user base, then switch new customers to recurring plans once you have proof. The lifetime deal is market research that pays you.

  3. Publish the numbers while they help you, hide them when they don't: Chen's monthly revenue posts turned a growth curve into a customer-acquisition channel — buyers could literally watch the product win. But he stopped the moment copycats started free-riding on his playbook. The mechanism: transparency is a tactic, not a religion. Share the metrics that build trust (revenue trajectory, customer count) while you're small and need credibility; set a tripwire in advance — a competitor cloning your positioning, say — and go quiet when it trips. Most founders either share nothing or share forever. Chen treated openness as a growth lever with an off switch.

Closing

Damon Chen's story is not really about testimonials, or PDFs, or even SaaS. It's about the compounding value of refusing to stop shipping. Four products earned him $3,027. The fifth earned him millions. The difference wasn't talent or timing — it was that the first four were cheap enough to survive, and the fifth was built from everything the failures taught. He never raised money, never hired a big team, never moved fast in the venture sense. He just kept launching, kept the losers small, and let one winner pay for all of it. "Craft your life, your way," he wrote. His way was simple: ship, measure, kill, repeat — until something refuses to die.
