MARKET ANALYSIS · AGENT 01

A real wedge: shared households have no tool for splitting groceries

Generated 2h ago from 14 sources + 2 huddle notes · Confidence: medium-high

Re-run

Ask agent

TAM

$38B

US online grocery spend

SAM

$4.1B

Renters 22–35 in shared homes

SOM · 3 yrs

$62M

1.5% of SAM via campus + city launch

Signals

31% of US renters aged 22–35 live with roommates or partners.

Grocery splitting is the #2 roommate friction (1.2k Reddit threads).

Instacart and Walmart+ have no multi-payer cost splitting.

Risks

Low willingness to pay; users expect free utility apps.

Retailer APIs are gated (Instacart Connect, Kroger).

Suggested: add a Pricing agent

Willingness to pay is your riskiest assumption. Test the $3/mo household plan Maya proposed in today's huddle.

Idea brief

Edit

PROBLEM

Roommates fight over who bought what and who owes whom.

FOR

Young renters in shared flats, couples, co-living spaces.

RISKIEST ASSUMPTION

People will pay for fairness, not just for the list.
