A mid-market private equity firm with a portfolio of 14 operating companies was losing a senior associate's week, every month, to portfolio reporting — and the GPs still didn't have a clean view of trends across the book. Every portfolio company submitted financials in a different format: different chart of accounts, different periods, different definitions of EBITDA, different file types. The 'reconciliation' work was actually an associate manually rebuilding 14 P&Ls into one comparable view, every month. GPs got trends late, and the trends were often wrong because the underlying reconciliation had errors nobody had time to catch. There was no single source of truth for any portco, let alone the portfolio — every conversation about a company started by re-establishing what the numbers even were. Timely portfolio visibility drives everything from add-on capital decisions to LP communications.
DealSage layered an AI reconciliation workflow onto the firm's existing process — no rip-and-replace. The firm had first engaged DealSage for new-deal triage (financials arriving as PDFs and Excels across different years and formats); the platform already had reconciliation functionality, which was tuned for the firm, and a custom Excel plugin was co-developed so users could drag-select years from spreadsheets or PDFs and reconcile them. The technical core marries the AI's strength at extracting and structuring messy data with a deterministic P&L schema: Google Gemini parses the documents, a GPT model (GPT-5.4) structures the output into a standardized P&L 'asset' with every line item tagged (COGS, OPEX, gross profit), periods standardized to ISO formats, and totals validated so errors surface for human review. Once it worked for triage, it was extended to monthly portfolio reporting across the firm's 14 portfolio companies: portcos email their latest financials straight to the DealSage agent — no login required — and the platform appends each month to a source-of-truth P&L per asset, so per-company trends accrue automatically with no firm template to fill in. A self-hosted OpenAI open-weight model triages the portco emails so the querying model (Claude Opus 4.8 or GPT-5.4, user's choice) can answer questions with the context the portco team already gave. On the roadmap: cross-portfolio benchmarking (comparing a cost spike at one company against similar holdings) and direct integration with portco ERP systems.
The firm first came to DealSage with a deal-triage problem: financials arrived as PDFs and Excels across different years, formats, and definitions, and associates were rebuilding them by hand to evaluate new opportunities. DealSage already had reconciliation functionality and tuned it for the firm, then co-developed an Excel plugin that connects to the platform so users can drag-select years — from PDFs or spreadsheets — and reconcile them. The technical core marries the AI's strength at extracting and structuring messy data with a deterministic P&L schema: Google Gemini parses the documents, a GPT model structures them into the P&L 'asset,' every line item is tagged (COGS, OPEX, gross profit), periods are standardized to ISO formats, and totals are validated so errors surface for human review. Querying runs on the user's model of choice — Claude Opus 4.8 or GPT-5.4 — and a separately self-hosted OpenAI open-weight model triages the portco team's emails so that context travels with the numbers. Once triage worked, the firm realized the same painful reconciliation ran every month across its 14 portfolio companies. DealSage extended it: portcos email financials directly to the agent (no login), the platform appends each month to a source-of-truth P&L per asset, and trends accrue automatically. The time saved — roughly 42 hours a month across the investment team's juniors and the portcos' finance teams — mattered less than the shift it enabled: the firm moved from a reactive posture, only getting involved when something was on fire, to a proactive one with no surprises, freeing the deal team to actually talk with portcos and guide them where needed. Data security was addressed via SOC 2 certification and a human review step kept in the loop. Time to live use was about three weeks.
Lower-middle to mid-market PE firms (~$100M–$2B AUM, 5–25 investment professionals) running platform or roll-up strategies, drowning in monthly portfolio reconciliation across 10+ portcos that submit financials in inconsistent formats — plus deal teams doing manual financial extraction during triage.
