TAM for cross-platform family / household management dashboard SaaS? interactive, integrates well with outlook/google calendar and engages kids in their daily tasks saving a lot of time and energy to busy parents

TAM TOP-DOWN

The full task management software market ($3.7B to $6.6B, 2026) includes B2B project tools irrelevant to household consumers. The parenting apps market ($1.28B, 2026) is the tightest confirmed proxy. A household management sub-segment is added by taking 17% of the low-end task management figure to represent consumer-household use cases, yielding $629M. Summing with parenting apps gives $1.91B; rounded conservatively to $1.5B to avoid double-counting overlapping users.

$1.28B (parenting apps) + ($3.7B task mgmt x 17% household slice = $629M) = $1.91B, rounded to $1.5B

TAM BOTTOM-UP

Global households estimated at 1.8B to 2.0B (UN triangulation from evidence). The evidence identifies 15% as family-with-children households (268M). Of those, 72% of parents with children under 10 use at least one parenting app weekly; applying 55% smartphone and willingness-to-pay filter to 268M yields approximately 100M addressable households. Blended annual price of $42 (midpoint of Cozi Gold $39, FamilyWall $44.99, Maple $36 to $60) applied across 100M units.

1.8B households x 15% family = 268M x 55% digital/pay filter = 100M x $42/yr = $4.2B

SAM FILTERS

Three filters applied to top-down TAM of $1.5B. Filter 1: English-first and Western-market bias (US, UK, Canada, Australia, Western Europe) accounts for roughly 30% of the global household base but 65% of SaaS willingness to pay; apply 40% geography-revenue weight. Filter 2: Integrated calendar plus chore plus kids-task differentiator appeals to dual-income households with children under 16; roughly 30% of Western digital households. Filter 3: freemium-to-paid conversion benchmark from Cozi (9M registered, assumed 10 to 15% paid) confirms low monetization; apply a 12% reachability factor to $1.5B TAM.

$1.5B TAM x 40% geography weight x 30% segment fit = $180M top-down SAM

SOM BUILD

Three funded incumbents (Cozi, FamilyWall, Maple) already occupy app-store shelf space; new entrant realistic share of SAM is 1% in year 1, 2% in year 2, 3% in year 3. At $180M SAM and 3% year-3 share, gross SOM is $5.4M. Cross-check: 128,571 paying households at $42/yr equals $5.4M; achievable via organic app-store and referral growth consistent with competitor acquisition patterns (no large sales teams observed in evidence).

128,571 households x $42/yr = $5.4M (= 3% of $180M SAM at year 3)
