Applied AI for the built environment.
Small Tiger Group is a deep-tech R&D practice for architecture, BIM, and construction. We advise AEC firms on where AI fits, embed with their teams to build it, and maintain a portfolio of products in daily use on real construction sets.
Strategy
Where AI actually fits in your practice, and where it doesn't. Roadmap work for firms figuring out their AI position — tool selection, pilot scoping, build-vs-buy. Short engagements. Defensible plans, not slide decks.
How it works →Staff
Embedded engineers and architects on your team for the duration of a project. We work inside your repo and your standards. We've shipped agent-callable CLIs and MCP servers under our own brand — we bring that to your roadmap.
How it works →Tools
Our own products, used today on construction sets. The proof that we ship. Each one has a public domain you can visit and use right now.
