Build your process-improvement case in minutes.

Answer a few plain questions and the wizard builds it — problem statement, computed baseline, goal, risks and plan. A case your sponsor can read today. Then run the whole improvement in one place, with the executive report one click away at every step.

Prove it as you improve.

New FlowTown · a free game

Learn flow by playing it.

Run Willow Bank in a sunny 3D town: customers queue at the vault, every team has one job, and the owner is watching the profit. The same ideas LeanProjax teaches, in a game you can play in your browser, on your phone or your laptop.

  • Find the bottleneck in a busy bank, and fix it before the queue grows.
  • Hire, train, move people, and decide when RPA bots and AI agents pay.
  • Your town keeps earning in its opening hours while you are away.

No download. Your LeanProjax account saves your town.

Who’s behind this

Built by the person who needed it

Hi — I’m Nasser. I’ve spent fifteen-plus years in operational excellence in the banking industry, and I love this craft. But every improvement project I was part of lived in four places at once — a slide deck, a spreadsheet, a stats package, an inbox. LeanProjax is the project as I always imagined it: one home, statistics built in. I built it for myself — then shared it, so anyone who does this work can benefit.

The banking project seasons in the LeanProjax Academy come straight from that world. Read the full story →

“The pilot is free because I’m trading access for feedback. Tell me what’s missing, what’s confusing, what would make this the tool you reach for — I read every piece of feedback myself.”
