Does Doe produce both top-down and bottom-up analyses?

Yes. Doe generates at least two approaches, typically a top-down analysis (starting from total market and narrowing) and a bottom-up analysis (building from unit economics up). Triangulation between approaches gives you a more defensible range.

Can Doe access paywalled reports like Gartner or Forrester?

Doe researches publicly available data. For paywalled sources, Doe often finds publicly cited excerpts, press releases, or summaries. If you have access to specific reports, you can provide them and Doe will incorporate the data.

How does Doe handle markets where data is scarce?

For emerging markets, Doe uses proxy indicators: adjacent market sizes, growth rates from analogous markets, job posting volumes, and funding data. The analysis clearly notes where proxy data is used and what the confidence level is.

Can Doe update a previous market sizing analysis with new data?

Yes. Point Doe at the previous analysis and it will crawl for updated data points, refreshing numbers while maintaining the same structure and methodology. Works well for annual updates or pre-board-meeting refreshes.

Can I use the output in a pitch deck or board presentation?

The Google Sheets model and Notion report are built to drop directly into pitch decks and board presentations. The structured format with citations meets the standard that investors expect.

Market sizing without the guesswork

Public data sources (industry reports, SEC filings, census data, analyst estimates) are researched and structured into TAM/SAM/SOM models in Google Sheets with full citations in Notion.

Automate Market Sizing Research or talk to sales

Investor-ready TAM/SAM/SOM analysis with cited sources, built from public data in hours instead of weeks. Doe researches SEC filings, industry reports, and comparable datasets, then generates multiple sizing approaches in Google Sheets with full citations in Notion.

What changes

Dimension	Before	With Doe
Source coverage	A handful of sources (what the analyst finds)	Broad crawl across public data sources
Citation quality	Inconsistent, sometimes missing	Every data point linked to source
Methodologies	Usually one approach	Top-down and bottom-up with triangulation
Confidence assessment	Implicit, unstated assumptions	Explicit confidence levels and sensitivity ranges

How Doe conducts market sizing research

Pulls SEC filings, census data, and analyst estimates

Web Research

Doe collected data points from SEC filings, census data, publicly cited analyst estimates, competitor revenue proxies, and industry reports — each tagged with source and confidence level

Builds top-down and bottom-up sizing models

Doe produced two TAM/SAM/SOM models with sensitivity ranges, documented assumptions, and triangulation between approaches — ready to drop into a pitch deck

Cross-checks sources and flags confidence gaps

Doe flagged 3 data points using proxy indicators and noted where direct data is unavailable, so you know exactly where the estimates are soft

Runs sensitivity analysis across key assumptions

Doe tested how the TAM shifts under different growth rate and penetration assumptions, producing a defensible range rather than a single point estimate

Writes the full research report with citations

Doe assembled a narrative report with methodology, source citations, confidence ratings, and an executive summary ready for your board deck

The question nobody has time to answer properly

The board wants a market sizing update for the annual strategy deck. The CEO needs TAM/SAM/SOM for the Series B pitch. The product team is evaluating a new vertical and needs to know if it's a $100M or $10B opportunity. Every one of these requests requires the same thing: weeks of research that nobody has time for.

Market sizing is a research-intensive, detail-oriented task that requires pulling data from dozens of sources: industry analyst reports (if you have access), SEC filings, census data, industry association publications, competitor revenue estimates, analyst blog posts, and job posting volumes as proxy indicators. Each data point needs to be extracted, validated, and cited. A credible market sizing analysis isn't a guess. It's a structured argument built on public evidence.
