SEQUESTO aOS
The agentic operating system for bid and tender teams.
Any file. Any process. Any user.
SEQUESTO aOS brings eight layers together in one governed system for tenders, questionnaires, and structured document work. A stable model foundation, a purpose-built runtime, specialist agents, connected knowledge, workflows that follow your process, collaborative workspaces, and auditability all reinforce one another inside one system.
Eight layers, each building on the one below.
The value of SEQUESTO aOS is not one isolated feature. It is the way each layer builds on the one below it and becomes more useful in combination.
LAYER 01
Multi-Model Intelligence
The stack starts with a dependable large-language-model foundation. In practice, most work runs on one primary model family, while the architecture is built to evolve as models improve.
LAYER 02
Agentic Harness
On top of the model layer, the harness turns capability into a controlled runtime. It governs tool use, function calling, memory, reasoning, and observability, and assembles each run around the task at hand.
LAYER 03
Agent Force
The harness powers James and the specialist agents that actually move the work forward. James is the orchestrator your team works with, while specialist behaviours handle extraction, drafting, review support, and document operations.
LAYER 04
Context & Knowledge
Useful agentic work depends on the right context. This layer combines institutional knowledge, connected sources, workspace-specific material, and memory of how the team works.
LAYER 05
Data & Integrations
The operating system becomes practical when it connects to the systems teams already trust. This layer brings in source systems, dashboards, MCP-based extensions, and custom integrations.
LAYER 06
Bid Capabilities
This layer shapes the aOS into a working environment for tenders, questionnaires, and commercial documents. Workflows, views, approvals, and collaboration can all be configured around how a team actually operates.
LAYER 07
Products & Interfaces
All of the power underneath only matters if the workspace is usable. This layer is where people, documents, visibility, and approvals come together in one interface.
LAYER 08
Security & Governance
The top layer makes the rest deployable in real enterprises. Traceability, usage visibility, access control, SSO, and certifications turn the system into something teams can operationalise with confidence.

Go deeper into the core building blocks of the aOS.
Multi-Model Intelligence
SEQUESTO runs most work on one primary model family and upgrades deliberately to the latest capable release. The architecture can evolve as models improve, but the priority is stability, quality, and consistency for the teams working on top of it.
Learn more →Agentic Harness
The Agentic Harness is the substrate behind how work gets executed in SEQUESTO aOS. It governs tool use, function calling, memory, reasoning, observability, and runtime safety so each task is assembled around the user’s request instead of pushed through one static chain.
Learn more →Agent Force
Agent Force is the specialist layer on top of the harness. James orchestrates the work, while specialist agents handle extraction, drafting support, review support, and document operations across tenders, questionnaires, and structured commercial work. The heavy lifting scales, but the final wording and approval stay human.
Learn more →Context & Knowledge
This layer combines institutional knowledge, connected sources, workspace-specific material, and memory of how the team works. It is what makes James and the wider system useful in live tenders, questionnaires, and structured document projects.
Learn more →Data & Integrations
This layer brings source systems, dashboards, MCP-based extensions, and custom APIs into SEQUESTO so teams can work inside SEQUESTO aOS without disconnecting from SharePoint, Teams and the rest of their operating environment.
Learn more →Bid Capabilities
This layer turns SEQUESTO aOS into a working environment for the operational realities of bid and tender teams. Workflows, views, ownership, reviews, and project structure can all be configured around how a team actually works rather than around one fixed process.
Learn more →Products & Interfaces
This is where the underlying architecture becomes usable day to day. Workspaces, editors, comments, split views, notifications, and approvals bring the team and the agentic system into one place without hiding complexity behind oversimplified tooling.
Learn more →Security & Governance
This layer is about proving what happened, controlling who can do what, and meeting enterprise security expectations without turning governance into a separate project. Traceability, usage visibility, access controls, SSO, ISO 27001, and SOC 2 Type II all support that goal.

SEQUESTO aOS is the agentic operating system for bid and tender teams: eight layers that work as one system, each building on the one below. A dependable AI foundation, a harness that controls how each task runs, James and his specialist agents, your company's knowledge, integrations, bid capabilities, a shared workspace, and security and governance. Together they let SEQUESTO adapt to the buyer's file, the team's process and every person on the bid.
Multi-Model Intelligence, Agentic Harness, Agent Force, Context & Knowledge, Data & Integrations, Bid Capabilities, Products & Interfaces, and Security & Governance. Each layer builds on the one below it.
No. SEQUESTO fills the buyer's most complex forms in their own file, not only questionnaires: Word and PDF forms with tables, checkboxes and tick-boxes, flat PDFs with drawn boxes, locked Excel sheets and PowerPoint templates.
No. SEQUESTO adapts to each team's own bid process: custom stages, fields, document types and workflows, without code.
No. SEQUESTO drafts from the documents a company already has, so there is no answer library to build or maintain.
SEQUESTO lets each company decide where its data is stored, in the EU or the US. The AI that works on it runs in the same region.
