Three ways founders build in public
A16z Speedrun explores three modern patterns of "building in public." First, product-led public launches that showcase frontier AI features — exemplified by Pencil reaching 100,000 users and announcing "Swarm mode," a six-agent AI design workflow. Second, public business-model pivots toward AI-native services, highlighted by Gainsight (Chuck Ganapathi) positioning an agent product called Atlas and signaling a shift from pure SaaS despite hundreds of millions in ARR. Third, using notable hires and unconventional roles as public signals — Jean‑Michel Lemieux joined Spellbook as an "Executive IC" after Spellbook’s $50M Series B. The newsletter also reports startup financings: Sekai raised a $23M Series A for an AI app creation tool and ZeroDrift raised a $10M seed to enforce compliance in AI communications.
