Architectural decisions in agentic operating systems. Writes on the governance layer, runtime primitives, and what most platforms get wrong about bid response.
Evrard t'Serstevens is SEQUESTO's co-founder and Chief Technology Officer. He holds the architectural decisions that define the platform. Where the market treats agentic systems as feature layers, Evrard built SEQUESTO as an operating system with agents as runtime primitives. That choice cascades into every capability the platform surfaces. He writes and speaks on the architectural consequences of treating bids as compound documents under agent assembly, and why most platforms get the governance layer wrong. His work ensures SEQUESTO's architecture remains legible to engineers and defensible under enterprise scrutiny.
