Patrick Dalvinck
CEO & Co-Founder
Patrick Dalvinck is the founder of SEQUESTO. He built the platform after watching bid teams spend years assembling the same responses, constrained by tools that treated knowledge as static files rather than governable assets. Patrick holds the conviction that agentic AI belongs in high-stakes commercial work only when humans retain strategy and judgment. He speaks openly about the trade-offs SEQUESTO has made: choosing governance over speed, structured knowledge over unstructured retrieval, and institutional control over algorithmic autonomy. His writing reflects the founder's stake in category creation. Patrick works directly with pursuit managers and bid directors to ensure the platform serves the governance requirements their organisations actually hold.

Stéphane Leroux
Founder, B4W Consulting
Stéphane Leroux is the founder of B4W Consulting, a Paris-based firm and SEQUESTO's partner across the French market. He has spent over 25 years in IT services sales, including extensive work in the SAP ecosystem, inside response teams competing for high-stakes contracts under unforgiving deadlines.
His conviction is operational: optimising the response process isn't a back-office concern, it's a structural growth lever for any services firm. The five questions Stéphane works through with every client trace the same line. Does the team genuinely understand the client context? What can AI take off the response work? Is the team organised as a project? Is the response strategy actually winning? Are the risks under control?
For SEQUESTO's content, Stéphane writes from the French market on how IT services firms adopt agentic operating systems in real bids, what changes in conversion rates and bid economics once the process tightens, and what separates the firms that get real value from RFP automation from those that don't.

Evrard t'Serstevens
CTO & Co-Founder
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.
