We raised $85M. It's taken 4 years to get to this moment. Exa began as a gnawing itch. What if Google was outdated? What if you could use transformers to build perfect search over all the world’s information? What if we were the ones who did it? In 2021, this sounded crazy to…

Believing that the more money a startup raises the faster it will move is like believing that the more calories a person eats the faster they will run. Diminishing returns at first, actively counterproductive at some point.

Don't take money from an investor you have moral qualms about because of valuable connections they claim to have. Being upstanding matters more in the long term than connections.
Before we mock “shrimp on treadmills” or “marbles in cats,” remember: we once studied Gila monster spit and it led a drug that’s now reshaping modern medicine. How many influencers & politicians perpetuating memes actually read the studies? Probably none. So I’ll do it for you.

@harjtaggar One of the best antidotes to this loneliness is to be friends with other CEOs. This is one of the subtler benefits of YC, and frankly one that we never anticipated when we started it, but I think it has been very useful for the CEOs of the most successful companies.
Offdeal (YC W24) is reinventing investment banking for SMBs and just closed an incredible Series A. Congrats @leveredvlad and @alstonthelin on the big milestone!!!
