Validation · Experiment
A public, zero-spend validation run: nine business ideas, fourteen days, each with its own landing page and its own pass/fail threshold — a booked call, a $1 refundable deposit, a written reply. One gets built, and the data behind the pick gets published with it.
Next.js · Landing Pages · Validation
Analytics · Funnels
The instrumentation behind the demand test — nine landing-page funnels compared side by side, so the decision at the end is read off a chart instead of argued. Access is allowlisted, so the public entry point is the sign-in screen.
Next.js · Analytics · Supabase
PropTech · MCP
Real-estate underwriting as an MCP server. One address returns ARV, rent estimates, comps and ownership, then renders the same packet five ways — investor, GC, lender, CPA, title — with the source and fetch timestamp printed beside every figure.
MCP · Real Estate · Next.js
Research · Data Viz
168 game mechanics, 618 games, 394 studios and 4,366 inheritance links from 1962 to 2025 — grouped by the design problem each mechanic solves rather than by genre, with every one traced back through its ancestors.
Data Viz · Ontology · Research

Worldwide, country and city leaderboards for the most active developers on GitHub — with the contribution heatmaps, rank-movement bump charts, tile-grid maps and follower/output scatter that a table of follower counts cannot show.

Multiplayer AI workspace where a team and AI agents ship one repo together over a shared live transcript — from idea intake to a human-approved, merged pull request.

Next.js · Marketplace · Payments
