Thanks to the HN community! Everything started with this post from over 5 years ago [1] which gave Taimur and me enough conviction to quit our jobs to work on Causal full-time.
A few months later we launched an Excel sensitivity tool [2]. In 2022 we shared how we scaled our calculation engine to billions of cells [3] and a few months ago we had a successful Show HN of Causal 2.0 [4]
The product is now used by 100s of startups (many YC companies) and we're exited for the next chapter fo faster GTM with Lucanet!
