Wajo Fieldnotes
Essays from the people designing, building, and operating Wajo – shared while the ideas are still warm.
Assistants that act can let their users down in two ways: doing what the user never agreed to, or giving up on errands that get hard. We built an evaluation that scores both on the same runs, and used it to measure Fo against three base models and two open-source assistants, OpenClaw and Hermes.

Assistants that act can let their users down in two ways: doing what the user never agreed to, or giving up on errands that get hard. We built an evaluation that scores both on the same runs, and used it to measure Fo against three base models and two open-source assistants, OpenClaw and Hermes.
The era of assistants is giving way to the era of agent operators. Today we are launching Wajo: agents that come with their own inbox, phone number, voice, and credit card, and the builder that lets anyone create one. Meet Fo, an agent that gets $h!t done for you.
Wajo builds Action Agents — agents that guarantee outcomes, not just tokens. Agents acting in the physical world can't be graded on text alone. So we built a world where they take real action: real accounts, synthetic websites, simulated voice callers on a foreign voice stack. Fo, one of our products, hillclimbs in it.
