TAM/SAM/SOM that shows its work — top-down and bottom-up, every figure traced back to the source it came from.

Top-down and bottom-up TAM/SAM/SOM with every figure traced back to the source it came from.

The problem isn't finding a number. It's defending it.

Anyone can paste "$47B market growing at 12% CAGR" into a deck. The hard part is the partner who asks where that came from, whether it's revenue or units, what year the base is, and why your SAM is a third of TAM instead of a tenth. A single unsourced figure can sink a whole diligence call.

This agent does the part that actually takes days: it searches across analyst summaries, government statistics, company filings, and trade-body reports, browses the full pages instead of trusting a snippet, and reconciles the conflicting numbers it finds. When two sources disagree on the base, it tells you both and which one it used.

What it pulls together into one brief:

The output is a cited brief and a Sheets model you can hand to an investor or a board, where every assumption has a footnote and you can change one input and watch the rest move.

Frequently asked questions

Does it just make up a CAGR like other AI tools?

No. It only reports figures it found in a source it browsed, and it attaches that source to the figure. If it can't find a credible number, it says so rather than inventing one. The whole point is a brief that survives diligence.

Top-down or bottom-up?

Both, in the same brief. Top-down pulls from published market reports; bottom-up builds from unit counts, ARPU, and penetration. When the two methods diverge, that divergence is flagged so you know where the model is fragile.

Can it use a paid data source I subscribe to?

If it has a REST API and you give the agent the key, yes — it calls the endpoint with your auth and pulls the numbers in. For sites without an API it browses the pages directly, including JavaScript-heavy ones.

What do I actually get at the end?

A cited brief (every figure footnoted) plus a live Google Sheets model with editable TAM/SAM/SOM formulas. You can export the brief to PDF or forward the Sheet to whoever needs to poke at the assumptions.

Can it keep a market estimate current?

Yes. Set a scheduled task in plain language — say, monthly — and it re-runs the research, updates the model, and emails you a short note on what changed and why. You don't re-do the work each quarter.

How much does it cost?

$49/month or $490/year — cancel anytime. Setup takes about four minutes: name the agent, point it at your first market, and it runs the research while you watch.
