FinalDose

Programmable DNA drug destroying all cancers, unlocking 80% of targets

About FinalDose

FinalDose is building the first programmable drug - a single smart drug molecule that you can insert any diseased genetic code and it can search and destroy cells upon DNA recognition. Unlocking 80% of undruggable targets today. Starting with all cancers.

    🤓 Join us!

    🤓 Join us! One of the most interesting times in biology! We're working on the Final Drug to end cancer. In 50 years, when people look back, this would've been the most obvious bet on the largest drug category that yet to exist - DNA-triggered cell elimination. Join us! We're...

    Thank you all, Y Combinator had been surreal! Especially Garry Tan and Grey Baker and everyone we've met in and out of batch. SF is indeed a magical place. The people there are the most ambitious bunch building things that no other places would even dare bet on. It's founders and investors and strangers alike. We have a group of amazing supporters that's got their front row seat to see cancer gone and we're here to make that happen! It's going to be a wild grind FinalDose Photo posted definitely without permission asked Steven Lin Li-Yao Huang …more

    Time constraint is an amazing forcing function. FinalDose is the only deep-tech biotech startup we know of in the Y Combinator P26 batch. Most people are riding the AI revolution wave and building really interesting software at insane speed. Some hardcore companies basically launch and ship every week. All while biotech can't move at transistor speed and has to wait for cells to grow for 3 days! That type of speed starts to feel foreign when you can prompt an entire company codebase into existence in an afternoon. A single result that actually means something can take a whole or many PhDs to produce. It's frankly painfully slow but the outcome can fundamentally shift society. When we first went into YC, we were worried as hell about the progress we can demonstrate in just 2 months. I mean it took me 3.5 years to discover just one novel link between epigenetics and metastasis during my Ph

    FinalDose YC Launch - A programmable drug that kills cancer by reading its DNA

    For 60 years, drug discovery has chased proteins. But ~85% of disease drivers don't have a druggable protein, making them unreachable for modern medicine. The deeper issue: most disease doesn't start at the protein, it starts in the DNA that codes for it. We built a...
