Pick a market and get an analysis with TAM/SAM/SOM, trends, headwinds, segments, competitive landscape and where the opportunity is.
TAM ~$8B, SAM ~$1.2B, SOM ~$60M. Major segments: business English (highest willingness to pay), exam prep (highest urgency), conversational (largest volume). Recommendation: enter via business English with corporate partnerships.
TAM $4.5B, growing 22% YoY. Crowded at the enterprise end (Sage, QuickBooks AI), wide open in the solo + small-firm segment. Recommendation: niche down to 1–10 person firms with workflow integrations they actually need.
TAM $14B but heavily commoditized. Margin pressure from Amazon brands. Recommendation: build a content + community moat (newsletter, podcast) before launching products.
An AI market analyzer that returns market sizing with method, trends, competitive landscape, segment table and a 30-day research plan.
Use it before entering a new market, before pitching investors, or to spot the most attackable wedge.
Total Addressable Market (TAM) is the entire opportunity if everyone who could possibly use your product did. Serviceable Addressable Market (SAM) is the slice you can realistically reach with your current model. Serviceable Obtainable Market (SOM) is what you can capture in 3–5 years given your resources.
TAM matters for vision and fundraising — investors want big markets. SAM matters for strategy — it sets your realistic ceiling. SOM matters for planning — it's the number your sales targets and capacity should be built around. A founder who pitches TAM but plans against SOM is doing it right.
The biggest mistake in market analysis is concluding 'the whole market is our customer'. Markets reward specificity. A product that's 'okay for everyone' loses to a product that's 'perfect for accountants in firms of 1–10 people'.
Niching down does three things: it lowers customer acquisition cost (you know exactly where they hang out), it raises conversion (your messaging is laser-targeted), and it lets you charge more (specialists charge premiums over generalists). You can always expand from a niche; you can rarely retreat into one once you've spread thin.
Underserved segments share three traits: real demand exists (people are paying for something today), current solutions are inadequate (complaints are loud and consistent), and incumbents are too big to serve them well (they're chasing enterprise deals).
Find them by reading 1-star reviews of competitors, hanging out in industry-specific forums, and asking customer-success teams what gets returned or churned. The gold is in the gaps where existing products are 'almost good enough' for a specific use case but everyone tolerates the friction because there's no alternative.
Markets are not static. Watch for four signals that change the analysis: (1) regulatory shifts — GDPR created opportunities in privacy tech worth billions. (2) Platform shifts — every Apple iOS update reshapes the ad-tech and consumer-app markets. (3) Big-incumbent moves — Microsoft buying GitHub reshaped developer tooling overnight. (4) Customer-behaviour shifts — remote work permanently changed what office software gets bought.
Re-run market analysis at least annually and immediately after any of those signals. The companies that won during the 2020 remote-work shift were the ones who re-analyzed within weeks, not the ones who kept executing the 2019 plan.
