AI agent force at the core

ABOUT SEQUESTO
Built by people who lived the problem. The agentic OS for commercial teams.
Patrick and Evrard founded SEQUESTO in 2020. They built the platform they wished they'd had: an agentic operating system that handles response management for commercial teams.

We built the solution we wished we had
SEQUESTO was founded in 2020 by Patrick Dalvinck and Evrard t'Serstevens. Patrick spent over a decade at Trend Micro as Vice President Continental Europe. Evrard built technology at N26 and earlier ventures across European tech.
Both had watched the same scene play out: commercial teams losing critical deals because the response couldn't go out in time. Or going out with errors that should have been caught.
The reason was always structural. Knowledge scattered across documents, drives, and people's heads. Each new RFP starting from scratch. No memory. No system.
Today, SEQUESTO handles response management for commercial teams in regulated industries. Life sciences. Financial services. Critical infrastructure. Consulting. An AI agent force drafts, sources, and routes. Knowledge stays in source systems. The agentic OS layers on top.
Every response, handled. The final word, yours.
Our Values
01
Purpose-built for bid & tender teams
Every feature we build starts with a real customer problem. We measure success by outcomes, not outputs.
02
Honest about AI
We don't oversell what AI can do. Every output is sourced, attributed, and traceable. No hallucinations.
03
Secure by default
Your proposal data is among the most sensitive in your business. We treat it accordingly, SOC 2, ISO 27001, GDPR. Built into the architecture, not bolted on top.
04
Continuous innovation
Every release extends the agentic OS. Bid and tender teams shape what comes next. We innovate.
