Keito (計時) — To measure time

Built by professionals who were tired of being overcharged.

Keito is a modern time tracking platform created by OSO, a London-based specialist software company. We didn't set out to build software—we built it because we had to.

The Origin Story

Like many professional services companies, we were using off-the-shelf time tracking tools that promised simplicity but delivered complexity. Year after year, the pricing went up while the features stayed stagnant.

We watched our bills climb not because we were getting more value, but because we were running a successful business. That didn't sit right with us.

We're a team of engineers who build event-streaming infrastructure and real-time data platforms for enterprises. So when we realized we were paying a premium for basic functionality, we decided to do what we do best: build it ourselves.

Why we built Keito

The catalyst was simple: price increases that didn't reflect value. We built Keito with a different philosophy.

Fair Pricing

No arbitrary price hikes. No penalties for growing your business. Transparent, predictable costs.

Real Workflows

Designed for how professional services actually work. Streamlined and integrated with WorkOS & Xero.

Quality First

We're not trying to be everything. Keito does time tracking exceptionally well without the bloat.

Craftsmanship

Built with the same rigor we apply to mission-critical infrastructure: robust, clean, and secure.

You'll love Keito if you:

  • Run a consultancy or professional services business
  • Are tired of tools that treat you like an ATM
  • Value simplicity and reliability over bloated features
  • Prefer vendors who respect your business

We might not be a fit if you:

  • Need highly specialized industry workflows (legal, medical)
  • Require extensive customization and white-labeling
  • Are looking for an all-in-one project management suite
