Today, we're announcing @thatch_ai raised a $108M Series C at a $1B valuation from @thegp, @IndexVentures, @generalcatalyst, @a16z. The idea we're betting on: healthcare serves whoever controls the dollar. For 80 years that's been the employer. We think it should be you.
How it compares
A launch means nothing against no one. These are the launches it is actually comparable to, and where this one sits among them.
| Compared with | Launches | Median views | This one | Rank |
|---|---|---|---|---|
| Funding announcement the same kind of announcement | 247 | 419K | 2.0x | 77 |
| under 5K followers accounts of a similar size | 627 | 227K | 3.8x | 137 |
| Every launch all of them, for scale | 1981 | 688K | 1.2x | 866 |
What this launch shows
From an account with 320 followers, this reached 2672.1 times the account's own following. Accounts in the same band, under 5K followers, reach a median of 161.4 times their following, so this travelled about 16.6 times further than usual for its size.
It ranks 137 of 627 launches from accounts that size. Against every launch in the directory it sits at 1.2 times the median of 688K views.
Every response ran below the directory's usual rate: 71 bookmarks, 42 replies, 36 quotes and 46 reposts against 215 likes. The post was seen more than it was acted on, which is common for a launch that reaches past the people who care about the category.
The first line is “Today, we're announcing @thatch_ai raised a $108M Series C at a $1B valuation from @thegp, @IndexVentures, @generalcatalyst, @a16z”, a first-person opening that the founder-account launches in the directory use most.
It carries a 1:00 video against a directory median of 65 seconds. Videos between 30 and 90 seconds have a median of 603K views in the directory.
The copy runs 43 words, about the usual length for a launch post here, where the median is 41. There is a link in the body, which costs a post some reach and buys it a place to send people.
It went out on a Tuesday. Launches posted on a Tuesday have a median of 651K views in the directory, and Friday is the strongest day at 880K.
How to announce a funding round covers this: the round is the news and the post has to turn it into customers and hires. For the next one, read launching a product on X from a small account: an account with 320 followers has to earn every view from outside its own following.
Virality without conversion is the guide for it: reach that outruns response is the pattern this guide is about. Every launch we track in Healthtech AI is on that vertical's directory page.
