* Fundraising CRM for founders manage their fundraise -- used by all founders

* Work at a Startup has 1M+ candidates on it, with 1000s of hires/year

We also want to work with people who love building full stack web apps. While our stack is Rails, React and Postgres, mostly we’re just a bunch of pragmatic builders who are excited about shipping and having impact.

Two roles are posted below: Investor Software and Post Batch (all SW after the batch).
