BOOTSTRAPPABLE

AI copilot for cofounders

TAM // TOTAL ADDRESSABLE MARKET

$0B

SAM // SERVICEABLE ADDRESSABLE MARKET

$0M

SOM 3YR // SERVICEABLE OBTAINABLE MARKET

$0M

Real problem, real buyers, but the SAM ceiling traps you below venture scale

Your TAM math only looks venture-sized if you count all 150 million global startups as buyers, which they are not, the paying cohort collapses fast once you filter for multi-founder teams willing to pay above free-tier alternatives like PitchBob and Notion. The 3-year SOM lands at $5.4M, roughly $20M short of the $25M threshold investors need to see for a credible venture outcome, and that shortfall is structural: your SAM is $180M in a category where Visionful is already positioning as 'AI cofounder,' Evalyze has 10,500+ founders on a free tier building switching costs, and Microsoft's 55%+ enterprise copilot share means any feature they ship into M365 or Teams for small business erases your wedge overnight.

Key risk

Founders default to $0 ChatGPT or $10 Notion; no evidence supports a premium price.

TAM // TOTAL ADDRESSABLE MARKET

$1.8B

Top-down: Global AI copilot market estimated $16.9–24.2B in 2025-2026 (ResearchAndMarkets, MeticulousResearch).

SAM // SERVICEABLE ADDRESSABLE MARKET

$180M

Assumptions applied sequentially to $1.8B TAM: (1) English-language or English-capable product reach: 60% of global startups are reachable via English-first SaaS, yields $1.08B.

SOM 3YR // SERVICEABLE OBTAINABLE MARKET

$5.4M

3-year SOM built bottom-up on customers × price × realistic share. SAM = $180M. Year 1: new entrant captures 0.5% of SAM = $900K.

>Methodology

TAM: Top-Down Narrowing

Started with global AI copilot market estimates ranging $16.9B–$24.2B (ResearchAndMarkets 2025, MeticulousResearch 2025). The wide range ($2.8B–$36.4B) reflects different scope definitions; the midpoint of the two most credible analyst estimates is ~$20.5B. Applied 15% weight to isolate standalone productivity copilots excluding coding tools (GitHub Copilot), embedded enterprise suites (M365 Copilot, Salesforce), and customer support bots. Then applied 60% to isolate SMB/startup segment vs. Large enterprise. Result: $20.5B × 15% × 60% = $1.845B, rounded to $1.8B.

$20.5B (midpoint TAM) × 15% (standalone productivity copilots) × 60% (SMB/startup segment) = $1.8B

TAM: Bottom-Up Cross-Check

Used 150M global startups (DemandSage, Embroker, LimelightDigital, three consistent sources). Applied 10% active-and-digitally-engaged filter (15M startups). Priced at $15/month blended (between Notion Plus $10/seat and GitHub Copilot Pro $10-$20/seat). Annual revenue potential = 15M × $15 × 12. This yields $2.7B, diverges from top-down by 1.5x, within the 3x acceptable range. Favored top-down conservative figure of $1.8B as the stated TAM.

150M startups × 10% paying cohort × $15/month × 12 months = $2.7B (cross-check; top-down $1.8B preferred)

SAM: Sequential Filter from TAM

Applied four sequential filters to $1.8B TAM: (1) English-language reach 60% = $1.08B; (2) tech-literate/AI-adopting founders 40% = $432M; (3) multi-cofounder teams specifically 50% (assumption, not directly sourced, flagged) = $216M; (4) willingness to pay above free-tier alternatives 20% = $43M. Adjusted upward 1.5x for per-seat pricing on 2-person teams = $65M granular SAM. Final SAM set at $180M (10% of TAM) as a standard nascent-category floor, flagged as low-confidence given no analyst isolates this segment.

$1.8B × 60% × 40% × 50% × 20% × 1.5x seat adjustment = ~$65M (granular); SAM stated as $180M (10% of TAM floor for nascent category)

SOM: 3-Year Customer Build

Priced at $20/month per user (blended: GitHub Copilot Pro $10, M365 Copilot $18, midpoint of evidence range). Year 1: 0.5% SAM share = $900K = ~3,750 paying users. Year 2: 1.5% = $2.7M = ~11,250 users. Year 3: 3.0% = $5.4M = ~22,500 users. Share percentages reflect nascent category, free-tier competitor drag (PitchBob free, Evalyze free tier), and incumbent shadow risk. 3% cap in Year 3 is conservative but consistent with EU AI Act compliance headwinds effective August 2026 and Microsoft/Google feature-copy risk.

SAM $180M × 3% (Year 3 share) = $5.4M | Implied users: $5.4M ÷ ($20/month × 12) = ~22,500 paying users

Competitors // Threat map

NameFundingPositioningThreat
VisionfulNot foundDirect: positions as 'AI co-founder for entrepreneurs, helping build, validate, and grow startups'High, directly occupies the same positioning; unknown scale but already in market with cofounder framing
PitchBobNot foundAI chatbot for startup documents, equity tracking, founder agreements; targets accelerators, incubators, startup studios, free pricingHigh, free tier creates powerful adoption anchor; institutional channel (accelerators) is the exact go-to-market a new entrant would target
EvalyzeNot foundAI investor matching and pitch deck analysis; 10,500+ founders already using it; free tier availableMedium, 10,500 founder user base represents meaningful network effect and data moat for pitch intelligence; free tier suppresses willingness-to-pay in the market
