Jason demos 37signals' real Basecamp account live, including work-in-progress features and internal projects. His logic: the cost of being guarded and nervous outweighs the risk of someone seeing something they shouldn't. Transparency is the strategy, not the risk.

David unpacks why the live format is irreplaceable: most expertise is tacit, embedded so deeply in practice that you can't articulate it even if you try. Written guides and polished videos can't capture it — it has to emerge in the spontaneous moment of showing someone something in real time [1] — David Heinemeier Hansson "So much expertise is tacit — you can't write it down because you barely notice it yourself. Live demos force that hidden knowledge to surfa…" 07:46 . He draws an analogy to pair programming: sitting next to a colleague as they work, you pick up tools, techniques, and mental models you'd never learn from documentation. David applies the same logic to university teaching — the best educators don't fully pre-script their lessons because the magic happens in live interaction with the audience. Jason then explains the deliberate choice not to share session recordings: showing up live is the point, and that exclusivity preserves the format's value. He also notes the unexpected benefit of using 37signals' real account — it forces him into corners of the product he rarely visits personally, keeping him sharp and revealing UX rough edges that daily use glazes over.
David's landmark Rails presentation 20 years ago was built around showing everything Rails removed — the 'negative space' of unnecessary toil — rather than what it added.
The most magnetic thing you can show customers is everything you've eliminated. DHH's landmark Rails demo 20 years ago was a series of 'look at all the things I'm not doing' — and the same magic fires up every time Jason shows a Basecamp account that replaces five fragmented tools.
Jason notices product flaws more quickly when demoing live for customers than during regular personal use, because the external audience activates a more critical perspective.
There's a different part of your brain at work when you're showing something to a real audience. You stop being forgiving. Jason regularly spots UX issues during live sessions that he'd gloss over in daily use — because showing someone else forces you to see through fresh eyes.
SiteGPT attracted over 1 million visitors and $500K in total revenue without spending a cent on paid marketing. The secret: engineering as marketing — building free tools that rank on Google.
Bhanu quit his first job after just 8 months, moved back to his parents' house to cut costs, and started building. One product sold for $250K; the next hit $10K MRR in its first month.
90% of SiteGPT's Google search traffic comes not from the main product but from ~50 free tools Bhanu built. Each tool targets a low-competition keyword and funnels users back to the paid product.
50,000 monthly visitors become 200 leads, 60 trials, and roughly 15–24 new customers per month at ~$100 average revenue each. Add a $1,700–$1,800 LTV and you have a very healthy SaaS.
Start with a blank Ahrefs search, layer in keyword filters (include term, KD < 10, volume > 1,000), list candidates in Notion, design a CTA linking to your main product, then score by volume, difficulty, build effort, and product relevance. That's the whole playbook.
Marketing feels painful for most builders. Engineering as marketing flips the script: instead of writing cold emails or blog posts, you build things — and those things rank on Google forever.
Don't spend months perfecting before launch. Ship the core feature, get real users, and let their feedback dictate the product roadmap. Premature polish is a trap.
SiteGPT launched and hit $10,000 MRR within its first month. That momentum was so overwhelming that Bhanu sold his existing SaaS, Feather, for $250,000 to free up all his time.
PropGPT launched with 20 downloads a day and strong influencer marketing but hit a ceiling at $1,000–$2,000 MRR. High download numbers masked a critical flaw: almost nobody stuck around after the free trial ended.
