What is the rough total addressable market

Top-down context:

If RevisionDojo eventually expands beyond IB into broader tutoring and test prep, it sits inside very large categories: private tutoring (~$92B, 2022 base) and global test prep (~$126B, 2024), implying a TAM in the low‑hundreds of billions Grand View Research, GIA/MarketResearch.

Bottom-up calculation:

For IB today, a simple bottom‑up uses current pricing and student counts: ~200k DP/CP students × ~$200/year ≈ ~$40M/year (narrow SAM). Expanding to all ~1.95M IB students at the same ARPU gives ≈ ~$390M/year (broader SAM) IB stats, IB facts, pricing.

Assumptions:

• Uses current consumer pricing as proxy ARPU (~$200–$230 per student per year) pricing.
• Student counts from IB: ~200k DP/CP candidates; ~1.95M across all programmes IB stats, IB facts.
• 100% conversion is a theoretical ceiling; school pricing, discounts, and regional pricing may lower realized ARPU.
