TAM // TOTAL ADDRESSABLE MARKET
SAM // SERVICEABLE ADDRESSABLE MARKET
SOM 3YR // SERVICEABLE OBTAINABLE MARKET
Absurd in 2008, obvious in hindsight.
The TAM was always enormous because you were digitizing offline spare capacity, not creating new demand. The 2008 bet was trust, liquidity, and regulatory survivability, not market size. Today this is a mature, winner-take-most category; the lesson is that huge TAM plus broken user experience can justify venture scale even when incumbents look dominant.
Key risk
In 2008 the risk was trust, not TAM math.
TAM // TOTAL ADDRESSABLE MARKET
$87B
Global short-term lodging spend addressable by peer-to-peer stays.
SAM // SERVICEABLE ADDRESSABLE MARKET
$22B
Urban spare-room inventory in OECD cities with tourist demand.
>Methodology
TAM TOP-DOWN
Global lodging spend was roughly $650B in 2008. Peer-to-peer eligible nights (leisure trips where travelers accept a stranger's home over a hotel) represent an estimated 13% of that spend.
$650B lodging x 13% addressable = $87B
TAM BOTTOM-UP
Around 220M households in tourist-relevant cities hold spare-room capacity. If 8% would ever list at an average $60/night for 80 nights a year, host-side supply supports a market of the same order.
220M households x 8% x $60 x 80 nights = $85B
SAM FILTERS
Serviceable market limits to urban OECD cities where payment rails, tourist density, and early-adopter trust exist, roughly a quarter of the global figure.
$87B x 25% urban OECD = $22B
SOM BUILD
A three-year build concentrating liquidity in 10 launch cities, taking a 10% commission on roughly $1.8B of gross bookings.
$1.8B bookings x 10% take rate = $180M
