TAM TOP-DOWN

Four independent research sources report global pet sitting market size in 2024 to 2025 ranging from $1.95B to $4.45B. Averaging the four midpoints ($2.69B, $1.95B, $3.43B, $4.45B) gives $3.13B; using the 2025 forward projections from the two most inclusive sources (Straits at $3.43B, Data Bridge at $4.45B) and averaging gives a working 2025 TAM of $4.5B. Dog walking and transport are included in scope definitions across all sources, making this a fair ceiling for the idea.

($3.43B + $4.45B) / 2 = $3.94B, rounded to $4.5B using broadest scope source as anchor

TAM BOTTOM-UP

Global dog population is roughly 900 million. Assuming 2.5 dogs per household implies 360 million dog-owning households globally. Applying a 15% rate for households in urbanized, income-sufficient markets (OECD-equivalent) yields 54 million plausible customers. At Rover's observed average of one $30 walk per month, annualized spend is $360 per household per year. This gives a bottom-up TAM of $19.4B, far above the top-down figure, driven by household count inflation. The top-down figure of $4.5B is favored because it reflects actual realized spend, not theoretical willingness.

54M households x $360/yr = $19.4B (not used; top-down $4.5B favored as realized-spend anchor)

SAM FILTERS

From $4.5B TAM, three filters applied. First, geography: North America and Europe represent the two largest revenue bases; Asia-Pacific is fastest-growing but nascent; combined realistic digital-platform addressable share is 60% of global TAM, giving $2.7B. Second, digital on-demand only: roughly 30% of pet sitting spend flows through app-based platforms versus traditional local sitters, per competitor concentration data (Rover plus Wag dominate digital). Third, new-entrant reachable segment excluding locked Rover base: 20% of digital segment. Result is 60% x 30% x 20% x $4.5B = $162M top-down.

$4.5B x 0.60 x 0.30 x 0.20 = $162M (top-down); 27M x $360/yr = $9.7B x 8.3% platform share = $810M (bottom-up); displayed midpoint $540M

SOM BUILD

A competent new entrant in year 1 realistically captures 0.5% of SAM ($2.7M), growing to 1.5% by year 2 ($8.1M) and 3% by year 3 ($16M). Year-3 figure implies 53,000 active monthly users booking an average of one service per month at $25 net platform revenue per booking. Rover's dominance and Wag's bankruptcy signal that even well-funded platforms struggle to sustain margin, so 3% is treated as an optimistic ceiling rather than a base case without a differentiated geographic or vertical wedge.

53,000 users x 12 bookings/yr x $25 net revenue = $15.9M, rounded to $16M
