Hi HN, I'm the co-founder/CEO of Causal. We just announced our acquisition: <a href="https://www.causal.app/blog/causal-joins-the-lucanet-group" rel="nofollow">https://www.causal.app/blog/causal-joins-the-lucanet-group</a><p>Just wanted to say a big thank you to the HN community —<p>Everything started with this post from over 5 years ago [1] which gave me and Lukas (CTO) enough conviction to quit our jobs to work on Causal full-time.<p>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]<p>The product is now used by 100s of startups (many YC companies) and we're excited for this next phase of growth within Lucanet :)<p>[1] <a href="https://news.ycombinator.com/item?id=19704418">https://news.ycombinator.com/item?id=19704418</a><p>[2] <a href="https://news.ycombinator.com/item?id=21625974">https://news.ycombinator.com/item?id=21625974</a><p>[3] <a href="https://news.ycombinator.com/item?id=32000400">https://news.ycombinator.com/item?id=32000400</a><p>[4] <a href="https://news.ycombinator.com/item?id=39755858">https://news.ycombinator.com/item?id=39755858</a>
Huge news, congratulations!<p>I was building something similar back during COVID, as LTSE's Runway stopped being improve, Summit (usesummit.com) pivoted to being a no-code tool and Obvious (YC S21 perhaps?) shut down.<p>Instead of building it myself, I found and have been using Causal actively since April 2021 and advocating for it ever since, using it heavily for my latest three ventures and just last month for personal use. It's so far one of my favorite products to use, on level with Linear in terms of quality!<p>I'm not a commercial user and might never be, but it has been invaluable for me in my commercial and personal uses for budgeting and forecasting.<p>Hope you can fit in great at Lucanet, and try your best to keep the free model available!
Congrats!<p>A related question, if you don't mind me asking: was acquisition your initial goal when you founded Causal, or did you just receive an offer you couldn't refuse?

Congrats!<p>Do you think the US flip made a meaningful difference (presuming you did it for US customer/investor access)? Lucanet is EU, so maybe it complicated it in the end
Excellent, well done. Looking forward to hearing a discussion about this on your podcast! Might you go chase some other startup ideas? Does this "validate" the career model of creating something new, for you? Or would you not do it again?
Congratulations Taimur! I started following you from your pod with your brother and was super interested in your foray into tech with a math background. It's great to see Causal take off over the years.<p>These damn math folks are out here trying to make everything multi- dimensional
Congratulations on the merger. This is not a percentage-based commissary in the marketplace of ideas. Hope to see further uses of the "multidimensional spreadsheet." It sticks out at you in every axis.
