Climate & Niche · Startup idea
SEC Scope 1-2 disclosure and EU CSRD are now compliance triggers for the long-tail SMB market. The carbon-accounting tool priced for that buyer is the wedge.
Why now
The enterprise market (Persefoni, Watershed) is mature. The SMB market — companies under 500 employees who suddenly need a disclosure — has no good tool priced under $5K/yr.
The idea you could build today
Connect to QuickBooks / Xero for spend data. Apply emission factors (EPA, EEIO) to map spend → emissions. Generate the disclosure PDF in the required format (SEC, CSRD). Per-company-disclosure pricing.

The three repos already trying
No repos in the current period have crossed our minimum-volume + sector match for this idea. That can mean two things — the niche is too new for public GitHub signal to show up yet, or the buildable wedge is genuinely greenfield. Either way, watch this page; matches refresh weekly.
Matched against the current-period startup signal panel (climate-tech, fintech). Rankings shift weekly as the underlying GitHub activity moves. Read the methodology.
The seed-round pattern hiding in the trendline
Climate-tech OSS with velocity in the "spend → emission" classification module are the seed-stage tells.
Enterprise. The SMB-priced version is the wedge — same disclosure problem, different buyer.
Use the signal, not just the idea
The repos above re-rank automatically as commit velocity, contributor growth, and new-repo creation move. Want the data feed for this idea wired into your own stack? The MCP server exposes every signal as a tool any agent host can query.
Updated 2026-07-14. The framing is editorial; the “three repos already trying” slot is generated from the live signal panel. Anonymity rule: we name public GitHub orgs, never individual founders or stealth teams.
