Best green commute planner for small teams

Roughly 12-18 dedicated green commute platforms exist globally, but most are enterprise-grade SaaS solutions built for corporate sustainability departments with six-figure budgets. The common failure pattern is feature bloat: they layer in carbon accounting, ESG reporting, team challenges, and API integrations when small teams just need simple, weekly route-sharing with basic emissions math. The gap isn't in the concept—it's in the pricing model and UX. Teams of 5-30 people would adopt green commute tools if they cost $15-30/month, not $500+. Right now you're stuck choosing between spreadsheets, public transit apps with no team logic, or overpaying for enterprise platforms. A vibecoder entering this space should obsess over one thing: making it trivial for a team lead to invite coworkers, see who's carpooling, and celebrate small wins (like 'saved 2 tons of CO2 this quarter') without needing a dedicated sustainability manager. The real opportunity is the mid-market gap—too small for Uber or sophisticated platforms, too serious about sustainability to ignore.
