Private-EquityDueDiligence:ATech-StackEvaluationFramework

Private-equity investment in financial services has accelerated dramatically in the past five years. Wealth management roll-ups, fintech consolidation, broker-dealer platform plays, and trust company acquisitions have all drawn institutional capital. In each of these transactions, the technology stack of the target firm has moved from a back-office afterthought to a deal-defining variable. A target with a strong IT program commands a higher multiple and integrates cleanly. A target with weak IT hides material liabilities that surface after close.

We run technology due diligence for PE firms and their operating partners on financial services transactions. The framework below is the standard we apply, with variations for asset class and deal size.

Phase One: Platform Architecture

The first phase of diligence maps the target firm's technology footprint. What platforms run the business? How are they integrated? Where does customer data live? Who operates them — internal staff, an MSP, the platform vendors themselves? The goal is a current-state architecture diagram, validated against source systems rather than relying on management representations.

For wealth management targets, the critical platforms are portfolio accounting (Orion, Black Diamond, Tamarac, Addepar, or legacy systems), CRM (Redtail, Wealthbox, Salesforce, or vertical-specific tools), performance reporting, client portal, custodian connectivity, and document management. For broker-dealer targets, add the order management system, clearing firm integrations, trade surveillance tools, and the supervision and archive platforms. For trust companies, add the trust accounting system and any specialized fiduciary tooling.

The architecture diagram also surfaces integration health. How are systems connected — real-time APIs, nightly batch files, manual reconciliation? A target running a modern API-based architecture with well-documented integrations is substantially cheaper to extend and integrate than a target running on overnight FTP batches that require specialist knowledge to troubleshoot.

Phase Two: Cybersecurity Posture

Cybersecurity diligence assesses whether the target has the control baseline that buyers, cyber insurers, and regulators expect. The evaluation covers identity, endpoint, email, backup, incident response, vendor management, and governance — the same topics addressed in a cyber-insurance questionnaire, validated with technical evidence rather than self-attestation.

Common findings include: MFA deployed partially rather than universally; privileged access management absent; EDR deployed but not monitored; backups present but not tested; incident response plan written years ago and never exercised; vendor management largely informal; training performed annually but not tracked. Each finding translates to a remediation cost, a probability of post-close incident, and a signal about the operating discipline of the business.

The most material cybersecurity findings are the ones that would prevent the target from closing the deal at all — active incidents in progress, unresolved historical breaches with ongoing regulatory exposure, or control gaps so severe that cyber insurance is not obtainable. These are uncommon but they do appear. The diligence process has to be thorough enough to find them before the transaction completes.

Phase Three: Compliance Readiness

The compliance layer is where financial services targets create the most deal-relevant risk. A target facing an unresolved deficiency letter, an active examination, or undisclosed regulatory exposure can impair the deal thesis substantially. The diligence evaluates the compliance program — written policies, risk assessments, CCO tenure and qualifications, training records, incident records, and examination history.

For RIA targets, the specific evaluation items include the Form ADV filings, the compliance manual, the annual review required by Rule 206(4)-7, the books and records program, fee billing practices, performance advertising compliance, the Reg S-P safeguards program, and the pay-to-play and political contribution controls. For broker-dealer targets, the list extends to FINRA filings, supervisory system documentation, the Rule 3120 report, the AML program, the written supervisory procedures, and the electronic communications program.

The outputs of this phase are a compliance risk score, a list of specific findings with severity ratings, and a remediation plan with cost and timeline estimates. Buyers use these outputs to adjust purchase price, negotiate representations and warranties, and structure the post-close integration plan.

Phase Four: Integration Complexity

For PE transactions that involve integration with an existing platform — a roll-up adding a tuck-in firm, a platform play consolidating multiple targets — the integration complexity evaluation is critical. The diligence assesses what it will cost, in time and dollars, to merge the target's technology with the acquirer's.

The highest-impact variables are data migration volume and quality, identity consolidation complexity (how many user accounts, across how many directories), platform overlap (which systems will be retained and which retired), and custodian connectivity. A target with clean data, a single identity store, and systems that align with the acquirer's standard stack can integrate in a quarter. A target with data quality issues, multiple legacy directories, and platforms that do not align can take a year or more and absorb significant operating resources.

The integration evaluation also surfaces risk around key personnel. If the target's technology runs on a small number of internal people with institutional knowledge, their retention through close and into integration is a material deal variable. Retention packages, transition services agreements, and knowledge capture protocols all enter the deal structure as a result.

Phase Five: Data and Intellectual Property

The data and intellectual property review validates what the target actually owns and what it licenses. Client data ownership is typically clear at a legal level but can be complex in practice — data stored in a vendor platform, exported to vendor analytics products, or commingled with other parties' data. The diligence confirms that the target's data can be extracted and retained post-close without ongoing vendor dependencies.

Software licensing is the adjacent topic. Most financial services targets use a mix of enterprise software licenses, SaaS subscriptions, and potentially some internal development. The diligence confirms license compliance, identifies any over-deployment risk, and validates that SaaS agreements transfer through a change-of-control event.

Proprietary technology — custom-developed client portals, in-house analytics tools, specialized modeling — gets a deeper evaluation. Is it documented? Is it maintainable? Who owns the code? Is the development process reproducible? A target whose secret sauce is an undocumented Excel model maintained by a single person is a different acquisition than one with a properly engineered platform.

Phase Six: Cost Baseline and Future Investment

The final diligence phase establishes the current IT operating cost baseline and identifies required future investment. The current baseline covers staff, MSP, SaaS, infrastructure, and cybersecurity spend as percentages of revenue. The future investment layer identifies what the target needs to spend post-close to reach the acquirer's operating standards — typically in cybersecurity, archive, identity, and integration.

This phase produces a pro-forma IT operating model that informs the deal financial model and the post-close integration plan. A target spending well below industry norms often has deferred investment that the acquirer will have to fund. A target spending well above norms may have a bloated stack that can be rationalized. Either case affects the go-forward economics.

Deliverables and Timeline

A standard PE technology diligence engagement on a financial services target runs three to five weeks and produces a diligence report, an integration risk assessment, a remediation plan, and an integration cost estimate. For larger or more complex transactions, the timeline extends to six to eight weeks with deeper technical testing and more extensive vendor interviews.

Our financial services practice supports PE firms and their operating partners across the full transaction lifecycle — pre-close diligence, close-period planning, and post-close integration execution. If you are assessing a financial services target and want a structured technology diligence, schedule a consultation to discuss scope and timing.
