Theta Lake

Theta Lake makes communications compliance software that captures, archives and supervises activity on video meeting, voice, chat and AI tools. Its financial services customers use it to meet record-keeping and supervision rules from FINRA, the SEC, the CFTC, the FCA and other regulators, and it also sells to government, education, healthcare and manufacturing organizations.

The platform pulls records from more than 100 sources through APIs built with the platform makers, including meetings, phone calls, in-meeting chat, polls and whiteboards, mobile text, email and output from AI assistants. Firms can use Theta Lake as their full archive, or as a connector that feeds an existing archive of record, with search and replay across conversations, legal holds and export. Machine learning and AI models flag compliance, conduct and data protection risks for reviewers, and selective archiving lets firms decide which users and features to capture. A real-time advisor shows meeting participants approved compliance guidance and personal risk dashboards.

Theta Lake is based in Santa Barbara, California, with an office in New York. Cisco, Salesforce, RingCentral and Zoom have invested in the company and resell it. In 2026 it added integrations with Anthropic's Claude Compliance API and CrowdStrike Falcon Next-Gen SIEM, and opened data centers in China.
