Cerenovus

Paid

AI operating partner that reads enterprise records to surface hidden inefficiencies and warn about breaking systems, every claim cited.

Cited Findings: Every claim opens downward to the original document — a quote that cannot be found in its source never enters the record, so audit and legal can trust each line.
Inefficiency Detection: Surfaces duplicate payments, missed discounts, zombie software seats, dormant vendors, stalled receivables, and process patterns that quietly drain margin.
Early-warning Signals: Flags promises past deadline with no fulfilling event, accounts whose rhythm broke, renewals about to close at last year's usage, and processes that stopped running.
Time-aware Ledger: Answers what was believed vs what was actually true at any past date, so last quarter's company is still queryable — critical for audits and post-mortems.
Independent Review Loop: Every finding is checked against its sources before it reaches the user; anything unresolved goes to a human reviewer instead of being silently dropped.
Numbers With Workings: Each figure ships with the calculation and the source documents behind it, so any line can be rerun, checked, or opened for evidence.
Zero-install Ingestion: Reads the records a company already produces with no installation and no user interviews required.
Segmented Solutions: Purpose-built jobs for Enterprise, Middle Market, Private Equity, Consulting, Secondaries/Continuation Vehicles, and Corporate M&A/Integration teams.

Margin Recovery Sweeps: Find duplicate vendor payments, missed early-pay discounts, and idle SaaS seats in weeks-of-history without a consulting engagement.
Process Bottleneck Discovery: Identify approval chains that reject nothing but add weeks, or work items that always route through one bottleneck person.
Executive Early Warning: Give CEOs, CFOs, and COOs a standing early-warning system so problems reach them while they're still small and cheap to fix.
Deal-side Due Diligence: PE, M&A, and integration teams can query years of a target's records for hidden risk with every claim cited to the source document.
Consulting Delivery Acceleration: Advisory firms use Cerenovus as their inspection layer so questions that used to take weeks of digging get an evidence-backed answer in minutes.
Complex Exit Support: Secondaries and continuation-vehicle sponsors get a time-aware record they can defend to LPs and auditors.
