AI that reasons is everywhere.
Reasoning that knows your business isn't

Our Vision

24/7 AI Analysts expediting every commercial decision

The smartest models in the world can reason. None of them know what NBRx means in pharma, how a P/V/M decomposition works in CPG, or what's driving variance in your Q3 close. We're building the layer that does — pre-loaded with the methods, vocabulary, KPIs, and reasoning patterns of the industries we serve.

We envision a future where every commercial leader — Brand, Market Access, Field Force, RGM, FP&A, RevOps — has an AI Analyst that already speaks the language of the business, watches the numbers that matter, investigates the moment something moves, and ships the finished work — 100Xing their team's impact.

With Tellius

Minutes

From the moment a number moves to a finished brief in your hands, in minutes not days.

The Problem We Solve

Dashboards show. Copilots wait.
Smart models reason in the abstract.
None of them know your business.

Commercial teams have more data than ever — IQVIA, Veeva, Nielsen, Circana, SAP, Salesforce, internal warehouses, plus tons of unstructured data: call notes, payer contracts, retailer scorecards, etc.

Frontier models have gotten measurably smarter, but when something moves — NBRx, share, EBITDA, pipeline coverage — it still takes days for an analyst to figure out why. By then, the quarter has moved.

We're the intelligence layer that connects everything — structured, syndicated, and unstructured — answers the why questions your dashboards and copilots can't, and recommends the next move.

AI performed, not just assisted.

01 / REASON

Reason across your data.

Structured, syndicated, and unstructured data, read as one. Industry methods, vocabulary, and KPIs pre-loaded — not generic reasoning bolted on top.

02 / RUN

Run on your objectives.

Missions pursue your goals 24/7. Investigations happen on cadence, not when someone files a ticket. Always-on, always working.

03 / SHIP

Ship finished work.

Briefs, decks, Slack summaries, Excel models — delivered in your template, to the right person, before they ask.

Culture & Values

How we build

We're solving one of the hardest problems in enterprise software: making AI useful for the people who actually run the business. That demands a particular operating tempo — curious, accountable, fast, and bold.

Stay Curious

We don't stop at the first answer. The interesting question is always one layer down — why the number moved, what the customer is really saying, how the architecture could be simpler.

Own It

We hold ourselves accountable for outcomes, not tasks. When something works, we share the credit. When it doesn't, we own the fix. No hand-offs to the next quarter.

Move Fast

Speed compounds. A week of hesitation is a quarter of momentum lost. We ship, we learn, we adjust — and we pivot the moment a better path appears.

Execute Boldly

Fast is necessary. Bold is what makes the work matter. We take calculated risks, push past the obvious answer, and aim for impact worth the velocity.

Leadership

The team behind Decision AI.

Backgrounds across analytics, data science, product, and go-to-market. One shared mission: help commercial teams decide faster, with confidence, in a market that doesn't wait.

Why AI Workflows Give Different Answers Every Time — and How to Make Them Deterministic

One of the biggest challenges organizations face when deploying AI agents and workflows is inconsistency. The same question can generate different answers, recommendations, or actions depending on context, prompts, model behavior, and execution paths. This blog explains why AI systems are inherently probabilistic, where variability originates in modern agent architectures, and why prompt engineering alone cannot solve the problem. It explores how leading enterprises are introducing deterministic controls through semantic layers, governed business logic, structured workflows, context management, validation frameworks, and agent orchestration.
