We launched HappyRank — to stop local businesses guessing their Google Maps rank

We kept seeing the same problem: a business ranks #2 when searched from their shop, but #14 two blocks away — and they have no idea 70% of their service area can't find them. Single-point rank trackers hide this. So we built HappyRank — an AI Local SEO OS with: - 7x7 / 13x13 Geo-Grid heatmaps via Google Places API (New) - block-by-block visibility - GBP sync, post scheduling & AI review replies to keep 100% response rate Stack: Next.js 16, Prisma, Azure OpenAI. We wrote up the playbook we use to take listings from #9 → #3 in 18 days here: https://happyrank.io/blog/google-maps-ranking-strategy-2026 Live at https://happyrank.io — Free scan available. Would love feedback from fellow hackers marketing local businesses. What's your go-to for tracking local rankings?
