@cem_ozcelik, thanks so much for hunting us! Hey PH’ers, I'm Yiğit, co-founder & GP of Vela Partners. Today we are excited to launch Vela OS! In 2017, we discovered that early-stage investors who invest in innovation were not innovating in their very own businesses. No AI, no data, just intuitio...
Hey @yigit, congrats on the launch and a cool idea! To play a devils advocate - if Vela OS is three time better compared to tier-1 VCs, why not just raise a fund and start investing into startups? Why share it with others? :)
congrats with the launch @yigit! this looks awesome.

No. Interest is launch-day attention. Engagement ratio is a better quality signal. The product with more discussions per interest point usually has stronger product-market fit.
How directly these products compete. Three or more shared categories means they're going after the same user. One shared category means they approach the space from different angles. Zero overlap and they probably shouldn't be compared.
Comparisons are generated automatically when two products have enough data overlap. If the pair you want isn't here, the products might be in different categories or too far apart in engagement.
Either the product didn't meet our engagement threshold, or it doesn't share enough category tags with the other product to generate a meaningful comparison. We'd rather show no comparison than a misleading one.
Each product's data reflects its launch period. The comparison shows both products' engagement metrics from when they launched. The build date at the bottom of the page shows when the index was last refreshed.
Not yet. Current comparisons use launch-period data only. Post-launch tracking is on our roadmap.
