Custena is an AI workspace for the investor-facing and fund-ops teams at private-markets fund managers.. Built for the investor-facing and fund-operations teams at private-markets fund managers: LP reporting, DDQs, ad-hoc LP and auditor requests, and reconciliation against the administrator. What the agent does: Ingest and normalize. Statements, notices and emails in any format, mapped into one current fund record. Grounded answering. DDQ and ad-hoc questions answered straight from that record, cited every time. Reconciliation. Catches when the administrator's numbers and your internal records do not match, down to the exact line. Every number is traced to source. You see where each figure came from and the exact math that produced it, so it can be checked before it reaches an LP. Built on what you already use, not instead of it. No migration, no re-homed files. Custena connects to the Excel, Outlook and data room you run today, reads fund data in place across administrator exports and systems like eFront and Investran, and layers the agent on top. It follows your SOPs, not ours. Custena picks up your firm's procedures from the documents you already have, then routes approvals, cites every source and honors side-letter terms the way your team already does.
