I read the founding stories of YC companies that started in non-tech industries. Here's the pattern.
A consistent thread in YC batches that doesn't get enough attention: the companies where the founder came from a completely non-tech background, a nurse who built healthcare software, a contractor who built construction tools, a chef who built restaurant management software.
I collected and read every founding story of this type I could find from YC alumni.
The pattern is remarkably consistent.
Phase 1: The founder knows the industry deeply and finds the existing tools inadequate. Not "I researched tools in this space." I tried every tool in this space for years and none of them understood how the work actually happens. and this is true for myself been 16+ years in construction and i cant find that suits my requirement...
Phase 2: The founder builds something crude for themselves. A spreadsheet. A script. A Notion template with automations. Something that works well enough for their specific workflow even though it wouldn't work for anyone else.
Phase 3: A colleague or peer sees it and asks for it. The request comes before the founder thinks of it as a product. This is the pull signal, someone outside the founder wanted the thing before it was packaged for them.
Phase 4: The founder packages it, shows it to more people in the industry, discovers the problem is universal. Not just their shop. Every shop. Every clinic. Every site.
Phase 5: The application writes itself. Because the founder has been living the problem for years, every YC application question has a specific, lived answer. They don't need to research. They're describing what they experienced.
This is founder-market fit made concrete. You can't manufacture Phase 1 quickly. But if you're in an industry with inadequate tools, you might already be in Phase 2 without realizing it.
Been collecting this story from last 5 Months, have collected about 86+ such founder stories, who pivoted, rejected, applied again and succeed at YC, happy to share if someone needs it...
Hot take:
The YC application doesn't get better the longer you write it.
It gets worse.
The best applications are written in 48 hours by founders who've been building for 6 months.
Write fast. Build long.
Contrarian: the YC brand signal is declining.
In 2012: "YC-backed" on a deck meant you were elite.
In 2025: 1,200+ companies per year.
The brand still matters. It opens doors faster.
But the signal-to-noise ratio is lower than it was in 2015.
What matters more than ever:
- your metrics.
- Your retention.
- Your growth rate.
.@paulg's quote is a good prompt for your agent to make anyone's writing more concise
"strive to make my writing unsummarizable, in the sense that it has so little fluff left in it that if you take any words out, as summaries by definition do, you lose a lot of interesting ideas"
i've been testing voice dictation, which then runs through this prompt, for messages to colleagues
