On Monday 28 September, Meta announced the Meta Enterprise Platform, a new business aimed at selling its artificial intelligence models, agents and tools to corporate customers. To run it, the company hired Chirantan “CJ” Desai from MongoDB, where he had been president and chief executive since November 2025. He becomes chief enterprise platform officer, reporting directly to Mark Zuckerberg.
Desai resigned from MongoDB the same day. MongoDB’s shares fell by roughly 17 to 20 per cent. And within hours the company announced that Dev Ittycheria, who had led it from 2014 to 2025 and had handed the job to Desai less than a year earlier, was returning as interim chief executive while the board searches for a permanent successor.
Three facts in one morning, and each of them is a lesson about succession.
The first is that a public company’s chief executive is a liquid asset. Desai had a track record across Cloudflare, nearly eight years at ServiceNow including as president and chief operating officer, and roles at EMC, Symantec and Oracle before that. People with that profile are not kept by contracts. They are kept by the job being more interesting than the next offer, and Meta’s offer was to build an enterprise business on top of one of the largest infrastructure spends in corporate history.
The second is the size of the market’s reaction. A fifth of a company’s value moved on the departure of one individual who had been in post for ten months. Piper Sandler called the reaction overdone and said the company remained well positioned strategically. Both things can be true: the business is unchanged and the market has just repriced the discount it applies to key person risk.
The third is the most instructive. The board’s answer was immediately available because the predecessor was still on the board.
That is not luck. Ittycheria moved to the board when he handed over, which is an arrangement that is often treated as a courtesy to the outgoing leader and is in fact an insurance policy. It cost the company nothing while nothing went wrong, and the day something did, it produced a credible, experienced interim within a single news cycle.
Any owner thinking about handing over should take that specific structure seriously, because the version most small businesses attempt is the opposite. The founder leaves completely, sells the shares, cuts the ties, and takes every relationship and piece of undocumented knowledge out of the door on a Friday afternoon. If the successor leaves eighteen months later, there is nobody to call.
The alternative is unglamorous and cheap. Stay on the board, or in some advisory capacity, with no operational role and no authority to interfere, for two or three years after handing over. You will almost certainly never be needed.
MongoDB needed theirs within four hours.
