SheetBridge (working name)
Idea status: Idea stage · Target: an MRR ladder ($1k → $50k) instead of one fixed number · Verdict: No as described. Go small, as two-way Airtable ↔ Google Sheets sync for ops teams. · Last updated: 30 Sept 2026
Start here → WHAT-TO-DO-AND-AVOID.md: odds at each MRR level (with conditions, ~15 hrs/week / full-time: $1k ~45% / 60%, $5k ~15% / 25%, $10k ~6% / 11%, $20k ~2% / 4%), 12 do's, 14 avoids, checkpoints.
Where this came from. This idea is C3 in the 30 Sept 2026 micro-SaaS idea catalog: "Google Sheets add-on that syncs one popular tool", with Sync2Sheets ($9k MRR, solo) as the evidence. It was not a feature list supplied by a founder, so there's no stated team, price or traction. See analysis/09.
Name. "SheetBridge" is a working name. Check trademark, domain and existing Marketplace listing names before using it publicly. "Sheet" + "Sync/Bridge" names are common on the Marketplace.
The idea as catalogued: a Google Sheets add-on, sold on the Google Workspace Marketplace, that syncs data from one popular tool into Sheets on a schedule or both ways.
The idea after assessment: the source tool is Airtable. It has no native Sheets sync, and the only dedicated add-on is free, rated ~2 stars and hasn't been updated since Sept 2024. The job is two-way sync with conflict safety, built to stay inside Airtable's 100k-calls-a-month API cap on the Team plan. The buyers are small ops teams whose finance staff, field staff and clients work in Sheets.
Research was run on 30 Sept 2026, with a confidence level on each claim. See research/10-verified-research.md.

Caveat
Team, hours per week available, geography, price and traction were never provided. The assumptions are in analysis/09. These are still unverified (see research/10):
- how many Airtable teams actually want their data in Sheets;
- revenue of any Airtable- or ClickUp-to-Sheets add-on;
- whether background sync can run on non-sensitive Google scopes;
- Airtable's terms on letting people without seats edit through a sync.
There is no verified base rate for new Marketplace add-ons reaching a given MRR.
