A YC founder on X: startup numbers first, then France vs America, 10K in eight months
Pierre-Louis Biojout is French, a YC alum, and lives in San Francisco. He had barely posted for half a year when his startup NanoCorp launched on Mar 5, 2026. He posted its numbers, "$193k ARR in 3 days", "$1M ARR in 55 days", then more and more long posts comparing France and the US. A post about his visit to an American emergency room reached 2.35M views. He says he hit 10K on Nov 2, posting about 1.3 times a day.

Summary
The play
Post every real milestone of what you're building, number first; then write long, sectioned comparisons from the two worlds you know.
Can you copy it? Our read
What you can copy is the method: number-first milestone posts while you build, and long comparisons from two places you know. What you can't copy is the startup and the two countries. Fits a founder or expat with a real project and a strong point of view.
- What it takes
- A project with numbers worth sharing, and a perspective from somewhere your readers aren't.
- Startup cost
- Time only; about one post a day.
- Time to a verdict
- Judge it over months: his launch posts reached tens of thousands, his first million-view post came seven months later.
- Window
- Founder ARR posts are crowded; the comparisons are his own.

Each bar is one day, in date order; its height is how many main posts (originals, quotes and articles; not replies) went out that day. This chart counts posts per day rather than listing each post. May 2–3, 2026 read zero for every account we track: a gap in the data.

Their own numbers, checked
His Nov 2 post summed up his eight months. We checked what can be checked against the public posts and daily post counts:

| "8 months ago … posts were hitting a few hundred views at best" | All 16 posts of his launch fortnight (Mar 5–18): median 1,574, best 32,822 | Does not hold for the launch weeks; posts before March are not in our data |
| "Now posts hit sometimes millions of views" | ER post, Oct 27: 2,352,769 | Holds |
| "Now some of them do millions of views" (Oct 7) | At that date the best post in our sample was 153,790 (Jun 24); September and early October are not in our sample | Can't check |
| "I have 10k followers" (Nov 2) | 10,642 on Nov 8 | Holds |
