Strategy and artificial intelligence
substans.ai clears your decisions in weeks, keeps your strategy running over time and builds, with your teams, the AI tools they actually use.
One senior partner, a former technology group executive, owns each engagement. He directs a platform of about thirty specialised AI agents, organised in seven teams, that run research, modelling and drafting in parallel. You pay for experience and results.
Price follows this production model. You pay for a senior partner's time; the agents that produce the analysis are not billed by the day. The price is fixed before kick-off and does not move.
| Commitment | What you get |
|---|---|
| Timeline | 2 to 6 weeks for a full study |
| Price | fixed before kick-off, for a written scope |
| Team | one senior partner and about thirty specialised agents |
| Evidence | two sources per figure, dated source appendix |
| Confidentiality | each client's data and memory kept separate |
You choose according to the decision at hand. Each practice already has client proof.
A complete strategy team serving you alone, over time. It sits with your executive committee, builds the plan, writes the board papers and drives the workstreams. No hire, for a fraction of the cost of an in-house team.
The equivalent of four experienced profiles
Market study, acquisition screening, due diligence, strategic plan. Ranked, costed and dated recommendations. Monitoring extends the study with a daily press review and alerts in a dedicated online space.
We start from the real work of a department. We map the flows, design the target model with the managers, propose the governance and support the roll-out until the first measured results.
Use cases chosen with the people who will do the work, specifications, development, application in service. Usage is measured in pilot before any scale-up.
95% of organisations measure no return on their generative AI projects, for lack of fit with daily work (MIT, 2025). We reverse the order: users first, then the tool.
The project closes with a measure of real usage. For a SBF 120 automotive supplier, a first tool ran live in front of the management committee and produced its cascade in seconds.
substans.ai has built its own AI agent platform. Guillaume Belin defines each agent's role, sources and rules, then assembles the team each engagement needs. The rules accumulated engagement after engagement belong to substans.ai and benefit every new client.
Mission, skills, authorised sources, limits and exit criteria: each agent has its brief, as a consultant has a scope.
Research agents feed the modelling agent, which feeds the drafting agent. For one client: a series of studies, a strategic plan and the board papers.
Every correction from Guillaume Belin or a client becomes a written rule, tested, then applied by all agents. A learned method serves every engagement; each client's data stays separated.
The reviewer is never the author. Two independent sources per figure, a contrarian agent, a blind fact review, a gate that blocks any contradictory document.
Engagements presented anonymously, in line with our confidentiality commitments.
Medium-term strategic plan, strategy section of board meetings, new governance and transformation workstreams. Plan adopted by the extended management committee.
Full market and commercial strategy study: strategy report, market database, capital cost matrix, European project tracker, alert note. Delivered in a few weeks.
Application that produces a full company map in under an hour, in the client's brand. Covered by automated tests and already used on large groups.
Communications department: workshop with the teams, prioritised use cases, action plan, management cascade tool demonstrated to the management committee, daily monitoring.
Acquisition screening across the cloud value chain: long list, short list, files on priority targets, executive committee note. Delivered in a few weeks.
International expansion: dynamic scoring model that ranks and sequences future store openings.
Agentic AI plan: shift from a service model to a mixed technology and consultant model, proprietary platforms, roadmap.
Map of the European datacentre ecosystem: hyperscaler investment, regulation, energy corridors. Tracker updated regularly.
Global cloud value chain and long-term high-performance computing needs. Growth niches ranked, investment recommendations.
Guillaume Belin led marketing and innovation at Atos, after leadership roles at Bull and SFR Business Team. He founded substans.ai to give executive committees top-level advice at the speed and price his AI agents make possible.
Each engagement starts with a 45-minute call, free of charge. You set out the decision; we tell you whether and how we can help. A written proposal follows with scope, timeline and a fixed price.
