Startup Spotlight is a weekly publication by Spencer Gareiss breaking down the startups worth watching.

From Pre-Seed to Pre-IPO, every issue digs into the companies, founders, and market shifts that matter. No fluff, no hype cycles, just clear analysis on who’s building what, how it’s funded, and why you should care.

Spencer brings a practitioner’s lens to every spotlight. He co-founded Robinhood Derivatives LLC, where he built futures, prediction markets, and equities shorting products from scratch in CFTC and SEC regulated markets.

Today he’s Chief Product Officer at /mkt, an athlete tokenization platform. He holds 8 FINRA licenses, passed CFA Level 2, and serves as a U.S. Army Reserve Captain. He’s also the author of Mental Models: How to Think, Act, and Win.

Who this is for:
Investors sourcing deals. Founders looking for pattern recognition. Operators staying sharp on what’s moving. Anyone who wants to understand what’s next before everyone else catches on.
