In this episode of Run the Numbers, CJ sits down with Jeff Bernstein, managing partner at Riveron, to unpack what really happens when a company decides it might be time to go public. Jeff draws on his experience across banking, hedge funds, operating roles, and advisory work to break down IPOs, dual-track processes, and the surprising realities behind price discovery—including why a 20x-oversubscribed book isn’t what it seems. He also dives into the re-emergence of SPACs, what’s different this time, and the key considerations CFOs should weigh before choosing that route. From IPO-readiness must-haves to building the muscle memory needed for public-company life to the sketchiest EBITDA adjustment he’s ever seen, Jeff brings stories, frameworks, and hard-won lessons for any finance leader thinking about the road to the public markets.
