Tessel · Operations platform
Quiet automation for serious operations.
Tessel runs the work between your systems. Every block is typed, every run is traced, and nothing sensitive happens without a person saying yes.

Three promises. We keep all of them.
01
Typed
Every block declares what goes in and what comes out. A change that breaks a type never reaches production.
02
Traced
Every run keeps its inputs, outputs and timings for 30 days. When something fails, you know which block and why.
03
Approved
Payments, refunds and access changes wait for a named person. Agents can suggest. Only people can sign.
One block, drawn in section.
Each workflow is three layers. Data comes in at the bottom, the work happens in the middle, and results leave from the top.

“The best software we bought this year is the one nobody talks about. It just runs, and when it can't, it asks.”
