About Tellen
Tellen is an AI workforce platform built for accounting firms that deploys intelligent agents to automate audit workflows across planning, fieldwork, reporting, and review. It operates inside a firm's own cloud infrastructure (Azure, AWS, or GCP), learning from proprietary data and internal policies while integrating with engagement tools like Wolters Kluwer, Thomson Reuters, Caseware, and Inflo.
Pros & Cons
Pros
- Outcome-based pricing avoids the per-seat cost penalty as audit teams scale
- Runs inside the firm's own cloud tenant, so client data never leaves firm control
- Purpose-built for audit workflows rather than a generic AI assistant
- Integrates with the engagement platforms accountants already use
- Backed by adoption at major firms including Grant Thornton, Baker Tilly, and CohnReznick
