Kesava Mandiga

Bio

Product marketing operator with 20 years across support, sales, operations, social media, content, and PMM. Founding PMM at Wingman through the Clari acquisition. First marketer at Fincent. Head of PMM at JustCall. The method is the same everywhere: customer interviews, a Value Proposition Canvas (Jobs, Pains, Triggers, Gains, Solution, Evidence), then messaging where every claim traces to a quote.

Builds in parallel: Flywheel (PMM operating model, on Claude Code and GitHub), the ab-codex corpus you're reading, and a personal agent ecosystem (miniu, Commons, Curiosity).

Voice

Writes like he's talking to a friend. Personal register, mid-sentence personality injection, throwaway humor, the occasional confession. Not the polished "operator voice" he prescribes for outbound — that's a separate discipline reserved for cold DMs and cover letters. Posts are conversational thinking-aloud, not posture.

AI-native isn't doing the same job faster, it's collapsing roles
