MongoDB CEO CJ Desai: hyperscalers running out of capacity, and "data is back"

Key takeaways from Sourcery with Molly O'Shea interviews with MongoDB CEO CJ DesaiDealroom has a profile for this one. Try Dealroom → (July 2026):

Hyperscalers hitting capacity limits. Desai described a top-50 customer of a major hyperscaler in Texas being told there was no capacity for additional cloud and AI workloads — prompting the customer to keep a data centre it had planned to decommission and run workloads on-premises instead.

AI-native startups running on MongoDB. He pointed to AI-native companies — naming the likes of base44 and ElevenLabs — building on the platform, with ElevenLabs alone running north of 50 million agents on MongoDB.

"Data is the unsung hero." Desai's thesis is that data — and by extension MongoDB — is back at the centre of the AI stack, serving frontier labs across use cases he could not disclose.

Lessons from John Thompson. At Symantec, the legendary CEO taught him how to work with customers — how much to listen versus talk — and to always dress well to signal respect for the customer.
