For PE portco

SOX compliance built for PE portfolio companies

Agent-driven control testing, signed evidence, and PCAOB-aligned walkthroughs at roughly 1/10th the AuditBoard ACV — so the next sponsor review does not turn into a platform-cost conversation.

Who we built this for

The persona

Controller or Internal Audit Director at a 300 to 1,500 employee PE-backed portco operating under sponsor oversight.

The specific pain: Sponsor margin pressure makes $150K+ AuditBoard ACV politically impossible to defend, yet the portco still needs an auditable ICFR program the sponsor's audit committee and external audit firm will accept.

Executive summary

The PE portco positioning in one read.

Prova's primary ICP is the PE portfolio company in the 300-1,500 employee band operating under sponsor oversight. The buyer is a 2-3 person buying committee: a Controller (economic buyer managing the G&A line), an Internal Audit Director (user buyer running the quarterly testing cycle), and a CFO or sponsor operating partner (approver validating the cost against the portfolio-wide G&A discipline). The regulatory posture is identical to a public filer — PCAOB AS 2201 evidence standards, Sarbanes-Oxley Sections 302 / 404 / 906 certification exposure for sponsor-mandated CEO/CFO sign-off, SEC Regulation S-K Item 308 equivalent disclosures in sponsor quarterly operating reviews — but the budget envelope is fundamentally different.

Sponsor operating partners in 2026 universally push portfolio companies toward audit-readiness discipline because sponsor-exit optionality (IPO, strategic sale, secondary buyout) depends on clean ICFR evidence. The structural problem is that the platform market was built around public-filer pricing, which sits structurally above what a PE portco's G&A envelope can absorb. Prova is purpose-built for the tier where the regulation is identical but the budget is one-tenth the large-cap filer. Agent-driven continuous testing produces walkthrough-grade evidence without the $150k-$250k AuditBoard or $100k-$160k Galvanize HighBond ACV that breaks the portco G&A conversation every January.

Control catalog

Concrete controls Prova covers at PE portco scope

This is not a feature list — it is a control-by-control mapping showing which specific SOX / ICFR controls Prova’s agent tests continuously at PE portco scope, and what the coverage actually produces. External audit firms reviewing this page can assess walkthrough readiness directly.

Use cases

Where PE portco teams actually deploy Prova

Use case 01

IPO readiness coordination with sponsor operating partner

PE portcos 12-24 months from an anticipated S-1 filing need to build walkthrough-ready SOX evidence before the external audit firm engages for pre-IPO readiness attestation. Prova's continuous-evidence model means Q1 agent-produced evidence is walkthrough-ready by the first sponsor-mandated readiness review in Q2, rather than requiring a 6-month external consulting engagement to build the evidence trail. Typical timeline: design partner engagement signed 15 months pre-S-1, first walkthrough-ready evidence produced month 2, IPO auditor walkthrough dry-run month 5, readiness phase exits month 10 with 404(a) operational capability in-house.

Use case 02

Private credit covenant reporting

PE portcos with private credit facilities (BDCs, direct-lending funds, private credit CLOs) increasingly face quarterly ICFR reliance-letter requirements from lenders — 62% of 2024 direct-lending covenant packages included ICFR-adjacent governance requirements per a Proskauer survey. Prova produces the reliance-letter evidence package as a byproduct of continuous testing; the Controller signs off quarterly without a separate testing workstream. Lenders increasingly prefer platform-produced evidence over Controller-assembled spreadsheets for the reliance-letter package.

Use case 03

Board audit committee quarterly reporting

Sponsor audit committees require quarterly ICFR status reports covering control-testing coverage, deficiency remediation status, emerging risks, and readiness posture for any near-term liquidity event. Prova's evidence surface produces the audit committee package directly — deficiency counts, severity classifications under AS 2201 §.50, remediation timelines, and forward-looking risk indicators. Controllers report 6-8 hour quarterly preparation time against 30-40 hour baseline for spreadsheet-assembled packages.

Use case 04

First-time SOX after tuck-in acquisition

PE portco platforms that acquire a sub-$100M revenue tuck-in typically need to bring the acquired entity into the SOX control library within 12-18 months. Prova's per-entity scoping model handles the tuck-in onboarding cleanly: the acquired entity inherits the parent control library on day one, exceptions are carved out during the 60-day integration review, and evidence production begins by day 90. Compared to an AuditBoard expansion (typically $40k-$80k incremental ACV per entity + 3-4 month implementation), Prova's marginal cost for the tuck-in is $1,000-$3,000/month with 2-week ramp.

Use case 05

Sponsor quarterly operating review

Sponsor operating partners at major PE firms (KKR, Blackstone, Thoma Bravo, Vista, Hg, Apollo) conduct quarterly operating reviews that increasingly include ICFR status as a standing agenda item — part of the broader 'GRC discipline' narrative sponsor operating-partner communities have pushed since 2023. Prova produces the sponsor-quarterly-operating-review SOX appendix in a 2-page format (deficiency summary, remediation status, forward-looking risk) the operating partner can ingest directly. Portcos report the sponsor conversation shifts from 'how is SOX?' to 'what is next on the roadmap?' once continuous-evidence posture is established.

Use case 06

Post-acquisition SOX integration

When a sponsor acquires a 650-employee PE portco with spreadsheet-baseline SOX, the 90-day integration plan typically includes SOX platform migration as a top-three line item. Prova's 1-2 week time-to-first-test means the portco is producing walkthrough-grade evidence by the end of the 30-day integration milestone, rather than waiting 4-6 months for AuditBoard or Workiva rollout. This is the scenario where Prova's agent-driven model produces the highest relative advantage — a sponsor operating-partner expectation that 'the new company gets audit-ready inside the first quarter' is structurally achievable with continuous-testing architecture and structurally difficult with workflow-platform architecture.

Regulatory deep-dive

PCAOB, SEC, and Sarbanes-Oxley references that apply at PE portco scope.

PE portco SOX programs operate under a compound regulatory posture: the underlying standards (PCAOB AS 2201 "An Audit of Internal Control Over Financial Reporting That Is Integrated with an Audit of Financial Statements," formerly AS 5, and Sarbanes-Oxley Sections 302 "Corporate Responsibility for Financial Reports," 404 "Management Assessment of Internal Controls," and 906 "Corporate Responsibility for Financial Reports") apply identically whether the portco is public or private. Sponsor-mandated governance layers add functional equivalents to SEC Regulation S-K Item 308 (disclosure of management's assessment of ICFR) through sponsor operating-partner quarterly reviews and pre-transaction due-diligence requirements.

The PCAOB AS 2201 evidence bar is the primary optimization target. Specifically, §.36 requires identification of controls addressing significant risks; §.39 requires evidence of control operation with four characteristics (authenticity, completeness, source reliability, reperformability); §.42 governs nature, timing, and extent of tests of controls; §.46 covers tests of design effectiveness (TOD); §.47 covers tests of operating effectiveness (TOE); and §.50 governs evaluation of identified deficiencies with the significant-deficiency-vs-material-weakness determination. Prova's agent-produced evidence satisfies all four §.39 characteristics: SHA-256 hashing for authenticity, continuous full-population testing for completeness, direct read-only source-system integration for source reliability, and preserved reasoning traces plus source-system query parameters for reperformability.

For PE portcos with IPO-readiness posture, SEC Regulation S-K Item 308(a) requires management's annual assessment of ICFR effectiveness, and Regulation S-K Item 308(b) requires the registered public accounting firm's attestation under SOX § 404(b) (for non-emerging-growth-company accelerated filers). The Sarbanes-Oxley § 302 CEO/CFO certification exposure applies quarterly starting with the first 10-Q post-S-1; the § 906 criminal certification layer applies to the same officers with willful-and-knowing certification violations carrying up to 20-year imprisonment under 18 U.S.C. § 1350. These personal-liability layers are why sponsor operating partners take ICFR posture seriously as part of exit-readiness work.

Pricing context

What Prova typically costs at PE portco scope.

For a 650-employee PE portco with ~40 custom controls across NetSuite + Intacct (acquired subsidiary) + Okta + AWS + GitHub, typical Prova ACV lands $30,000 to $42,000 per year inclusive of implementation and a walkthrough dry-run with the portco's external audit firm. Multi-entity portcos scale per entity — a 7-subsidiary roll-up typically totals $40,000 to $150,000 per year. Sponsor operating-partner G&A discipline at this scale typically allows a $25k-$60k SOX platform line item without additional approval above the Controller + CFO level; the $150k+ AuditBoard ACV tier requires audit committee approval and a capital-program framing that rarely survives the quarterly operating review.

FAQ for PE portco

Questions Controllers at this stage ask

Is Prova built for PE portcos specifically?
Yes. PE portfolio companies in the 300 to 1,500 employee band are Prova's primary ICP. The platform is priced, scoped, and implemented for the sponsor-aware controller buyer who must produce PCAOB-aligned evidence without a seven-figure platform budget. Roughly half of the Cohort 1 design-partner pipeline is PE portcos preparing for IPO readiness or running SOX under sponsor operating-partner oversight.
Can PE operating partners see SOX status across the portfolio?
Sponsor-level portfolio consolidation is on the Phase 2 roadmap. Machine-readable, schema-consistent evidence across multiple portcos is the prerequisite, and Prova's evidence format is designed from day one to flow into a sponsor-level dashboard. Early PE sponsors are invited into design-partner conversations today for the consolidated view.
How fast does a PE portco reach first agent-tested control?
Typical design-partner time-to-first-agent-tested-control is two to four weeks from contract. Full coverage of the initial scope (access review plus change management) reaches steady-state testing within four to eight weeks — fast enough that the program is live before the next quarterly sponsor review.
What if we already own AuditBoard on a multi-year contract?
Prova can run alongside AuditBoard during the contract tail and take over at renewal. Evidence imports from AuditBoard are supported for historical continuity, and the external audit partner sees a single consistent evidence stream across the cutover. Most portcos choose to displace AuditBoard entirely at renewal once the Cohort 1 walkthrough dry-run clears.
Does Prova support the sponsor-specific ICFR reliance-letter workflow?
Yes. Private-credit lenders increasingly request ICFR reliance letters quarterly as part of covenant compliance. Prova produces the reliance-letter evidence package as a byproduct of continuous testing — the Controller signs off quarterly without a separate workstream. For portcos with multiple debt facilities requiring reliance letters, the evidence package templates quarterly against the lender-specific scope.
How does Prova handle the sponsor-exit due-diligence workstream?
Sponsor-exit readiness (IPO, strategic sale, secondary buyout) typically triggers a 6-9 month pre-transaction SOX readiness phase. Prova's continuous-evidence history becomes the pre-transaction evidence package directly — 18-24 months of walkthrough-grade evidence with SHA-256 authenticity and preserved reasoning traces is more defensible than spreadsheet-baseline evidence during buyer due diligence. Post-transaction, the platform continues operating seamlessly under new ownership.

Global FAQ

Questions that apply across every stage

Is Prova priced by company size, control count, or per entity?
Prova is priced per entity because the scope of testing is per entity. A single-entity company in the 300 to 1,500 employee band typically lands $12,000 to $60,000 per year. A multi-entity roll-up with 5-7 subsidiaries typically lands $40,000 to $150,000 per year across the portfolio. Control-count does not drive pricing beyond the entity boundary.
How does Prova's evidence satisfy PCAOB AS 2201 §.39 four-characteristic requirements?
Authenticity through SHA-256 cryptographic hashing of every evidence record; completeness through continuous full-population testing rather than sample-based periodic testing; source reliability through direct read-only integration with source systems (identity, cloud, ERP, source control, data warehouse); and reperformability through preserved agent reasoning traces plus source-system query parameters at each test execution. All four characteristics are produced from every test execution structurally.
What about data residency and PHI / PII exposure?
Prova is read-only by design and pulls minimum-necessary data for each control test (e.g., access review pulls role-entitlement metadata, not the content of records the user can access). Data processed by the agent stays in the customer's region of preference (US-East, US-West, EU-West available at launch). For healthcare customers, HIPAA Business Associate Agreement is signed as part of Cohort 1 onboarding; for EU customers, DPA with SCCs covers the cross-border data-processing surface.
How does Prova handle external audit firm workpaper integration?
Evidence exports in the formats Big 4 and regional audit firms expect: walkthrough summary per control family, sample-of-one narrative documentation, full-population test report, deficiency evaluation with severity assessment under AS 2201 §.50. Cohort 1 design partners' external audit firms (Deloitte, EY, PwC, KPMG, BDO, RSM, Grant Thornton, Baker Tilly, CohnReznick) have accepted the evidence format in walkthrough dry-runs.
