Equities.fyi – Startup valuations based on public company data
With the current down markets, we were wondering what private company valuations looked like when compared to similar public companies. We were inspired by the a16z article (https://future.com/framework-valuation-navigating-down-marke...) for calculating valuations and figured out the sales-to-valuation ratio of public companies at the time of the last fundraising round and applied the change in the public market to get the current startup valuation. If things don’t look right, our defaults might be off - please feel free to change those if they’re too different from what…
In plain words
Equities.fyi estimates private startup valuations by comparing them to similar public companies. The tool uses the sales-to-valuation ratios of public companies at the time of each startup's last funding round, then adjusts for changes in the public market to calculate current valuation estimates. It's designed for investors and founders seeking realistic private company valuations during market downturns. Users can adjust default assumptions if needed.

Hello, HN - I wanted to share this puzzle game I made during my vacation. I'm rather fond of the pipes puzzle where your goal is to restore a scrambled network of connections by rotating tiles. It's usually played on a grid of squares and this all started when I decided to make a programmatic solver for that kind of puzzle. Then I realized that with some minor changes the solver could generate new puzzle instances. I thought about what kind of puzzle to make and someone suggested a hexagonal grid. Adapting the generator wasn't too hard but then I had to create a way to play this variant. So…
