Athennian enables legal, tax and finance firms and consultancies to manage client needs efficiently with streamlined workflows, real-time data and consistent access across teams and jurisdictions.
Solving for professional service needs
Support internal and client teams with secure access to accurate data and easy-to-use workflows, improving adoption and reducing back-and-forth.
Work across clients and systems without duplication or data loss, with entity data integrated across your tech stack for smoother workflows and reporting.
Automate manual processes, reduce rework and improve data quality so your team can focus on delivering high-value service, not fixing spreadsheet errors.
Private equity and fund management teams operate across intricate, multi-jurisdictional structures that demand precision, control and speed at every step.
When diligence stalls because no one can confirm the authorized signer on an SPV or auditors surface conflicting ownership records across shared drives, the problem isn’t your people — it’s fragmented entity data. These breakdowns create avoidable delays, last-minute fire drills and real compliance risk.
Athennian eliminates those failure points by centralizing fund, SPV and portco information in one governed, transaction-ready system. With centralized records, automated workflows and instant ownership insights, teams move faster on deals, reduce compliance exposure and maintain investor confidence in every decision.
