So — what's Span?

In 1975, AI didn't have a budget line. Now it's one of your biggest

Your engineers are using more AI tools, more models, and more tokens every month. The spend is climbing — but the honest answer to "is it actually making us better?" is usually a shrug.

That's where Span comes in. We help engineering leaders manage AI spend with context — seeing usage and cost by team, tool, model, and outcome, so you can tell where AI is creating real leverage and where it's just burning budget.

Span AI spend report

01

See how AI spend is trending

Monitor actual and projected AI spend, so you can spot budget pressure early and adjust before spend diverges from plan.

02

See the real model mix

Understand the actual mix of tools and models in use, and know where AI spend needs support — or a closer look.

03

Compare cost to impact

See team-level spend alongside throughput, cycle time, and quality — so you know where AI usage is creating leverage.

04

Connect spend to work

Trace AI spend to the PRs, projects, and initiatives it supports, so you can see where tokens are going and why it matters.

Real impact for real customers

The proof is in the people
