Senior Software Engineer, Full Stack / Agentic Engineering

About Distill Distill gives every founder and executive a "mini-me" that does outreach for them. Customers would rather hear from founders than salespeople, but founders don't have the time. Distill does it for them: deep research on each person, tight and human messages that get industry-leading response rates, turning cold outreach into real conversations. Distill is backed by top tier VCs (funding has yet to be announced) and was founded in 2024 by Russ Heddleston and Tim Su. Both are multi-time founders with exits under their belts who love building usable, delightful B2B software that targets the end user.
