Hours Saved Per Review

Traditional FDD is broken for lower-middle-market deals

2-4 Weeks

Traditional FDD takes weeks. Deals move fast. By the time you get the report, the window may have closed.

Hours of Manual Work

Manual workbook prep, period mapping, and add-back identification eat dozens of analyst hours per deal. Time you could be spending on judgment, not data entry.

Missed Red Flags

Many advisors skip thorough diligence on smaller deals or rely on manual Excel reviews that miss critical patterns.

What Our Engine Catches

Not just numbers. The story behind them.

high priority

Revenue Concentration

A single customer drove 28% of March revenue. Without them, growth was flat.

high priority

Expense Misclassification

Contractor payments booked as COGS should be SG&A, inflating gross margins by 4 points.

medium priority

Cash vs Accrual Gap

Cash basis reporting understated receivables by $180K. Accrual reconstruction reveals a different picture.

medium priority

Seasonal Inconsistency

Q4 revenue pattern broke from prior years, suggesting a one-time event being presented as recurring.

medium priority

Vendor Concentration

Top 3 vendors represent 72% of COGS. Supply chain risk not reflected in the narrative.

low priority

Working Capital Trend

DSO increased from 34 to 52 days over 12 months while revenue grew 8%. Collection issues emerging.

These are real examples of findings from our analysis engine, anonymized from actual engagements.

turnaround compression

“We used to spend two days putting together a workbook before deciding whether to even submit an IOI. Now we run it the same morning the teaser hits our inbox.”

in flagged add-backs we'd have missed

“The EBITDA bridge caught owner-perk items the seller's broker had buried in OpEx. Renegotiated the LOI based on the cleaner number.”

“Pre-Zenith, I'd look at maybe two targets a quarter because the spreadsheet work was so painful. Now I run it on everything that lands and only spend real time on the ones with clean signals.”

Data room

Self-serve buyer Q&A

Less-experienced buyers stall when their questions go unanswered. Give them an AI that's (optionally) informed by the deal so they can get accurate answers immediately. Keep more buyers moving toward an offer.

What's driving the gross margin expansion in FY23?
Deal Q&A
Margin expanded ~4 pts driven by mix shift toward enterprise contracts (now 38% of revenue, up from 24%) and renegotiated hosting terms in Q2.
Customer concentration?
  • Per-recipient access controls. Each buyer sees only what you allow.
  • Answers grounded in the deal's actual financials, not guesses
  • Fewer dropped processes, less management bandwidth burned
