Evidence, and the reading behind it.
Case studies of how real products actually found their first users, the principles the board argues from, and notes from building Newma itself.
The metric between signup and retention
Signup is not the finish line. The moment that decides whether someone comes back happens later, and most products never name it.
How TelemetryDeck turned a free iOS chart into a press magnet
A free iOS market-share chart became a press magnet nobody else was giving away. TelemetryDeck's public iOS version-adoption survey pages turned into a go-to source cited by 9to5Mac, Forbes, iOS Dev Weekly, and the Wall Street Journal — free data doing the work most companies pay PR agencies for.
How Hypefury got 1,000+ paying customers by building in public
Hypefury exists because its founder couldn't find a tool that did one specific thing. Samy Dindane tweeted in August 2019 asking if any scheduling app supported Twitter threads; finding none, he and co-founder Yannick Veys built the first one, prioritizing shipping over design.
How Tailscan validated in one week and grew to $1,600 MRR
A 9-month failure taught the founder to validate in a week, not build for months. Erwin's prior product, Base Styles, died after nine months with ~100 trial users and $0 revenue; for Tailscan he gave himself one week to build something and post it on Twitter before writing another line of code.
How Zapier turned unanswered forum requests into $140M ARR
The idea came free, from other people's unanswered complaints. The founders found their first validation on Highrise, Evernote, Dropbox, and Salesforce forums, where paying SaaS customers had been begging for integrations — one thread had 400 comments and no answer.
How HostiFi built a $3M/year business in a niche inside a niche
A niche inside a niche inside a niche let one non-developer founder plausibly reach the whole market by hand. Reilly Chase didn't target "Ubiquiti users" — he targeted the specific slice of IT/MSP businesses that resell Ubiquiti hardware, a market small enough that DMs, forum signatures, and one Twitter account could plausibly cover it.
How SavvyCal beat a free incumbent by picking its market first
Derrick Reimer spent months choosing SavvyCal's market before writing code, filtering explicitly for audience overlap. After his prior product Level failed, he ran candidate markets through filters — existing demand, a shippable MVP, few decision-makers, no native-app requirement, and overlap with his existing podcast/Twitter audience — and scheduling passed.
How Buttondown grew 61% in a year with zero ad spend
Buttondown's entire growth engine is word of mouth — no ads, ever. The founder is explicit that while rivals buy Super Bowl ads and spend millions luring users onto their platforms, Buttondown relies solely on people liking the product enough to tell a friend or colleague.
How Instatus reached $141K ARR by emailing every signup
The free-forever plan didn't create paying customers by itself — the founder emailing signups did. Instatus offered unlimited free status pages from the start, but 'during early months, no one would upgrade'; conversion only picked up once the founder personally reached out to new signups, which he credits for landing brands like Sketch and Restream.
How Pirsch Analytics grew to $14K MRR, then hit a crowded market
A side project built to fix the founder's own analytics annoyance became the entire product. Marvin Blum built the open-source Pirsch Go library in June 2020 to track his own blog without cookies or Google Analytics — then productized it in October 2020 after his first startup, Emvi, failed to compete with Notion and Roam Research.
The polish trap
Why building feels safer than marketing, and how to notice when “one more improvement” is helping you hide.
How Leave Me Alone won 426K users by publishing its metrics
The public metrics page went live before a single dollar of revenue existed. Leave Me Alone published its open startup page showing real numbers — revenue, costs, users — before it had any revenue to show on it, turning a privacy promise into something checkable rather than a marketing claim.
How Senja reached $10.8K MRR by fixing onboarding, not marketing
A widget embedded on customer websites became its own distribution channel, but only after the product had something worth embedding. Senja's testimonial widgets sit on customers' own sites and are seen by their visitors, so every new paying customer quietly advertised Senja to their own audience — but this loop only started compounding once the onboarding fix (below) got users to actually publish testimonials instead of abandoning the app.
How Browserless turned open source into a $3.6M ARR funnel
A support headache at his day job became the product. Joel Griffith noticed he and his colleagues spent roughly half their time helping users get headless Chrome running, and only 5-10% of their time building real features — so he built Browserless to be the fix he wished he'd had.
How NoteForms hit $37K/month by filling a gap Notion left open
A missing Notion feature, built in days. Julien Nahum noticed Airtable had a form-to-database feature Notion lacked, and shipped the first Notion form builder the moment Notion's API made it possible.
How ScrapingBee reached $1M ARR by charging from day one
Two failed products taught them to charge from day one. After ShopToList (sold, never monetized) and PricingBot (no traction), ScrapingBee's founders closed their free beta after about a month and started charging immediately — the first paid customer arrived 50 minutes after the email went out.
