Casey Winters observes that new products succeed most often when they are the only remaining path for the company to keep growing, and when the CEO is genuinely, personally invested in them — not when they're run as diversified "portfolio" bets sized by a fixed percentage of resources. He explicitly rejects fixed-percentage portfolio allocation in favor of committing to one focused bet aimed at the specific weak link identified via A Second Product Only Needs to Fix One Weak Link.
This is a sharper claim than generic explore/exploit portfolio thinking (cf. Explore/Exploit Dual Portfolio Management): Casey's version says the bet should be singular and existential, not spread thin, and that founder conviction is a leading indicator of success, not a nice-to-have. See Operator/Zero-to-One Mismatch for the related staffing implication — founders can't fully delegate this to hires without zero-to-one experience.
Casey argues explicitly against allocating a fixed percentage of resources to "innovation" as a portfolio-style hedge. Instead: forecast the core product's growth S-curve, identify the specific point/lever where growth will bottleneck, and commit one large, targeted bet aimed at that exact weakness — rather than spreading resources across several parallel, low-conviction innovation bets.
This is the resourcing counterpart to why second products succeed as "the last path left": if the bet is sized and timed to the actual forecasted bottleneck, it isn't one option among a portfolio of hedges — it's the mechanism the company is relying on to keep growing.
