Darrell Silver

Running 503 Corp to launch tech companies with underappreciated founders. We believe that companies and careers will be better with fewer cost centers. I also serve as board member, advisor, and investor across EdTech and child advocacy.

I've co-founded+CEO'd+sold two companies: Thinkful (acquired by Chegg) & Perpetually (acquired by Dell). Before that a quant.

I'm married to @stephenfoley and live in NYC. Don't work in crypto.

503 Corp

Our view is that companies by 2030 will hire great experts that come bundled with best in class software, so we're seeing where that's most true. We build Service First: Bootstrap for the first few million then raise money when a product can become a monopoly.

  1. Union – Your dedicated People Operations and Recruiting partner. Co-founder Ben Aronowicz, former Head of People at Thinkful.
  2. FaaS – Growth modeling for startups once reserved for public cos. Co-founder Parniyan Cagatay, former FP&A at Chegg.
  3. GoodGig.work – Upwork without the bad clients. Co-founder Blake Gillette.
