Builds Archive

Short-cycle builds, pivots, and lessons worth keeping.

Hackathons, builder tracks, and fast prototypes that taught me something useful. This archive covers 8 builds across 7 focus areas, and 2 of them carried on after the event ended.

Problem

Early-stage Canadian startups often have to run go-to-market themselves across disconnected tools, limited distribution networks, and expensive sales workflows.

Build

We built 100users, an AI GTM agent for early-stage startups that combines prospecting workflows, parallel scraping, and memory-backed agent coordination into a single agent-first system.

Takeaways

  • Parallel scraping became the main technical bottleneck, so speed and coordination mattered more than adding extra features.
  • Even without pitching, finishing a working system proved the idea was worth continuing after the hackathon.
  • Hackathons do not always end cleanly, but real momentum still comes from shipping something useful.
