## TL;DR

Topaz Therapeutics is a small, early company in San Francisco that says it is building a platform for new cancer drugs. It has not said publicly what those drugs are.

## Summary

Topaz Therapeutics' website states only that it is developing a platform of next-generation oncology drugs; OrbiMed's portfolio page says the same. A company profile on Venrock's job board places it in San Francisco, lists 1 to 10 employees and says it is operating in stealth mode. No programmes, targets, trials or financing amounts have been made public.

## Fields

- Kind: Company
- Last checked: 2026-11-04
- HQ: San Francisco, CA
- Type: biotech
- Website: https://www.topaz-tx.com/

## Notes

- Stealth company: no pipeline, trial or financing details found.
- The Venrock job board lists Topaz and gives a founding year of 2024; that is a portfolio job board rather than a financing announcement, so neither Venrock as an investor nor the founding year is recorded.
- HQ comes from the Venrock job-board profile; the company site gives no address.
