Regisseur and Vertical AI. The platform and the point.

Vertical AI solves one operation beautifully.

Vertical AI has been the breakout enterprise category of the last three years. Sixfold in life underwriting, Harvey and Spellbook in legal, Notable and Abridge in healthcare, o9 and Project44 in supply chain. These companies have built deep domain expertise into focused products that solve one operation extraordinarily well. They will keep winning deals on the strength of that depth.

Regisseur does not compete with a vertical AI vendor on their best day in their core operation. We compete with the aggregate of vertical vendors a regulated enterprise will need across the full set of operations they run. That is a different fight, and it gets more important the more AI an enterprise deploys.

When one painful operation needs the best point solution.

You have one operation you need to improve, urgently. You know exactly which operation. You have budget for one AI procurement this year. You are willing to integrate a new vendor into the systems of record that surround that operation. You expect that vendor to own their workflow end to end, including the AI, the data extraction, the human-in-the-loop UX, and the regulatory positioning for that specific operation.

If that describes you, buy the best vertical AI vendor for that operation. Do not try to make a platform fit a problem you can solve with a point solution. The first AI procurement at a regulated enterprise should almost always be a vertical product.

When the second, third, and fourth AI procurement expose sprawl.

You are looking at your second, third, or fourth AI procurement. You have already bought one vertical AI product and you are starting to see the cost of vendor sprawl: a different audit story for each vendor, a different human-review UX for each vendor, a different integration footprint with the same underlying systems of record, a different compliance posture for each. Your CIO is asking how many AI control planes the enterprise will be running in three years. Your CFO is asking why each new operation is a fresh procurement instead of an incremental configuration.

Or — you are starting from scratch and have already concluded that the cost of running five vertical vendors in five operations is greater than the cost of running one platform configured five ways. This is the strategic AI buyer, the one whose CTO has been through the vendor-sprawl problem before with a different category and is determined not to repeat it.

Regisseur is built for both of those buyers.

Same primitives. New vertical as configuration.

The word "platform" is overused in enterprise software. Most "platforms" are products with an SDK. Regisseur is a platform in the structural sense: every vertical we serve is configured from the same four primitives (process, tools, agents, integrations) with no special-cased engineering per vertical. This is not a marketing claim — it is the architecture.

The practical consequence: when a vertical AI vendor in your industry releases a feature you want, your only path to that feature is procurement. When the same feature is requested in Regisseur, it is configuration. The Chief Underwriting Officer who wants to add a new lab biomarker to the underwriting decision does not file a vendor support ticket. They open the workflow builder.

This is the same architectural move Salesforce made against vertical CRM in the 2000s, and Workday made against vertical HR in the 2010s. It is not always better at the vertical's core operation on day one. It is almost always better at the enterprise's aggregate operation by year two.

The platform owns the operation. The vertical vendor owns the model.

We do not pretend the comparison is always a one-or-the-other. The most sophisticated AI buyers we talk to use vertical AI vendors as components inside Regisseur workflows — Regisseur orchestrates the process, holds the case, manages the human review, and produces the audit trail, while a vertical vendor's model handles the specific reasoning task it was built for.

This is the right architecture for many enterprises. The platform owns the operation; the vertical vendor owns the model. The boundary is the place where most enterprise AI vendor sprawl gets resolved.
