Power your reputation algorithm

At the heart of OSO, is a unified events model that links users, developers, and applications. Build multi-dimensional reputation models on rich history.

How It Works

OSO does the hard work of cleaning up event histories from many diverse platforms so that you can focus on the algorithms that matter. Spend time experimenting, not plumbing.

Unified Semantic Layer

Operate at the level of users, events, and applications with time-stamped events and relationship data. Don't waste time on data cleaning.

Flexible Experimentation

Use any algorithm you want, from custom scoring algorithms, to graph-based algorithms like PageRank and EigenTrust. Experiment in notebooks, deploy in production.

Diverse Data Sources

Take advantage of a data marketplace of GitHub data, blockchain data, and social network data. If you need something we don't have, let us get it for you.

Deep Historical Event Logs

OSO cleans and unifies event data from any data source in our marketplace, spanning decades of user-level actions, from git commits to user application transactions.

Hear from our partners

OpenRank

We're working with OpenRank to rank developers and GitHub repos on recursive trust for the entire GitHub activity graph. We also have a public version of their trust scores for Farcaster users.

Passport

We work with Passport on trusted user labeling and identity management. We maintain a public dataset of their address scores, which gets leveraged for onchain impact measurement.

Octant

We've tracked multiple cohorts of open source projects funded by Octant over successive funding rounds. Our coverage shows how Octant's funding has been instrumental in keeping these projects building during a choppy market.
