In their words

o11 is the AI data warehouse for financial firms. The largest firms build a moat around their data. Today, they pay engineers $200k a year each to spend years organizing/maintaining disconnected sources in a legacy data warehouse. The business intelligence that results is the key unlock, but it's time effort and money that would be better spent elsewhere. o11 brings a custom ontology and data model to firms of any size allowing them to unify CRM, email, files, data rooms, market data, M365, etc. all in one place. We help firms architect their own data warehouse, and then from their AI maintains it. No engineers, no legacy solutions, no complex migration. o11 is built for security and complex permissions from the ground up allowing it to safely connect directly into any agent including Claude, ChatGPT, and Copilot. Leverage your proprietary data -- it's the deal, relationship, and business intelligence that makes your firm special
