What to Build | India case study | Checked 2026-10-19
Product: https://www.getinboxzero.com/

## Buyer
Founders, executives, small teams using Gmail/Outlook

## Observation
AI email assistant and new open-source email client; sorts mail, drafts replies and supports team comments. Founder says 25k+ sign-ups at Oct 18 launch.

## Revenue
>$10k MRR (Oct 2025; historical, not current) (founder_reported). Verify the dated source; pricing is not revenue.

## Opportunity hypothesis
Hypothesis: focused inbox workflow for Indian export-service SMEs with Hindi/English drafts and WhatsApp or CRM handoff; crowded category.


## Alternatives
MailSage https://mailsage.in/ ; Hiver https://hiverhq.com/

## MVP
Scope one buyer and workflow after interviewing buyers.

## Non-goals
Avoid a broad platform before validating the workflow.

## First five buyers
Founder-led LinkedIn outreach to export-service operators

## 48-hour test
Interview 10 export-service founders; manually triage 2 inboxes; seek 3 paid pilots after comparing MailSage and Hiver.

## Continue if
A buyer commits to a concrete follow-up under an agreed success condition.

## Pause if
Existing alternatives solve the job or the buyer will not commit.

## Build instructions
Run the test before specifying software.
