Six-week IT Due Diligence Initiative
Architecture, security, compliance, vendor risk, key-person dependency, and IP. Structured against the standard buy-side technical diligence dimensions. Identifies red flags with directional mitigation cost sizing for deal modeling. Sized for lower-mid-market targets (typically under $100M revenue or fewer than 500 employees). Core-mid and upper-mid deals require an extended scope or specialty-firm partnership. Four weeks for focused buy-side reviews; five to six for full sell-side preparation or multi-domain diligence on more complex targets.
Who this is for
Mid-market technology diligence across architecture, security, compliance, vendor, key-person, and IP.
PE / Sponsor
You need a focused technology diligence on a mid-market target without committing to a big-four cycle that pushes the deal calendar.
Operating Partner
You inherited a portfolio company and need a technology baseline in the first 100 days.
Founder / CEO (sell-side)
You are preparing for a transaction and want the technology story documented, tight, and ahead of buyer questions.
Investment Bank
You need a technology section in the CIM that holds up under buyer scrutiny.
Scope
What this initiative delivers, and what it does not.
Scope is fixed at signing. Items tagged TOP are available inside the broader Technology Operating Partner retainer; the initiative alone does not include them. Items tagged with an outside source require a separate specialty engagement.
In scope
- Architecture diligence (stack inventory, integration map, scalability signal, technical debt)
- Security diligence (identity posture, control coverage, recent incidents, breach history)
- Compliance diligence (framework status, audit history, open findings, change-of-control regulatory exposure)
- Vendor and contract diligence (concentration risk, renewal timing, change-of-control clauses)
- Key-person and team diligence (single points of failure, knowledge concentration, attrition risk)
- IP and licensing diligence at the architectural level (license types, third-party dependencies, open-source posture)
- Red flag register with mitigation cost estimates and deal-impact framing
- Findings written in IC-review diligence-report format
Out of scope

Inputs
What we need from you
Provided at kickoff. Missing inputs delay the initiative; they do not change scope.
- Confirmation of sell-side or buy-side context, deal stage, and target announcement date
- For buy-side: read-only access to relevant data-room sections (we review in the seller-hosted environment; we do not export or store)
- For sell-side: read-only access to the target company technology documentation in the seller-hosted environment
- Management interview slots (six to ten interviews across CTO, CISO, GC, CFO, key engineers, depending on depth)
- Confidentiality and NDA aligned to standard transaction terms before access is granted
Timeline
Week by week
Daily visibility throughout. Mid-initiative check confirms direction before the deliverable lands.
Week 1
Scoping, access, kickoff
Context confirmed (buy-side vs. sell-side), NDA executed, access provisioned to the seller-hosted environment, interview schedule locked.
Week 2
Architecture and security diligence
Stack inventory, integration map, identity posture, control coverage. Initial management interviews with CTO and CISO.
Week 3
Compliance, vendor, and key-person diligence
Framework status, audit history, open findings. Vendor concentration and change-of-control clauses. Key-person and attrition exposure.
Week 4
IP, mid-Initiative check, draft brief
IP and licensing diligence at the architectural level. Mid-Initiative check with sponsor or seller. First draft of diligence brief shared for direction.
Week 5 (sell-side or complex buy-side)
Red flag synthesis and remediation sizing
Red flag register quantified. Directional mitigation cost sizing for deal modeling. Sponsor or seller review.
Week 6 (sell-side or complex buy-side)
Final brief and walkthrough
Final diligence brief delivered. Walkthrough with sponsor, deal team, or seller. Focused buy-side reviews typically land at end of week 4.
Output
What you walk away with
- Written technology diligence brief covering architecture, security, compliance, vendor, key-person, and IP, in IC-review diligence-report format
- Red flag register with mitigation cost estimates and deal-impact framing
- Walkthrough call with sponsor, deal team, or seller
Honest framing
What this initiative is not
This is a mid-market technology diligence brief. It is not a forensic audit, not a formal third-party opinion, and does not carry indemnification. Forensic code-level IP review, adversarial security validation, and quality-of-earnings work are outside scope and should be engaged through specialty firms. We do not host, store, or transfer deal documents: all review happens in the seller-hosted data room or environment, and the diligence brief is the only artifact we deliver. Mitigation cost estimates are directional and intended for deal-modeling, not for final remediation contracting.
If you are a portfolio company
How the work calibrates to the PE-backed seat.
Companies inside a PE portfolio operate against constraints generalist enterprise framing does not cover. Each of these shapes how the Initiative is scoped and sequenced.
- Board reporting cycle. Output is sized to land before the next quarterly board read, not the company's annual planning calendar.
- Exit window math. Decisions made 12 to 24 months ahead of exit show up at the bid. Where applicable, findings are tagged for the exit-window timeline they affect.
- Add-on integration tempo. Findings that pertain to acquisition integrations are surfaced separately so the deal team can either price them in or sequence the integration around them.
- Cost discipline by hold position. Recommendations are calibrated to where the portco sits in the hold cycle. A company in early hold has different cost flex than one 12 months from exit.

FAQ
Questions buyers ask first
How long does IT due diligence take in a PE deal?
Two to six weeks is the working range for IT due diligence inside a mid-market deal. Smaller deals or clean targets land at two. Regulated, multi-entity, or carve-out targets stretch to six. Preside runs an accelerated IT diligence in 10 business days when the deal timeline demands it, with a written tech-debt and integration-cost estimate the partner can take to the IC.
How much does IT due diligence cost?
IT due diligence typically lands between $50,000 and $500,000, scaled to deal size, complexity, and regulatory exposure. A clean mid-market target runs $50K to $150K. A regulated, multi-entity, or carve-out target stretches above $250K. The number the deal team should care about is not the fee. It is the post-close surprise the diligence catches. Preside reports tech debt as a dollar number against EBITDA, so the PE firm can price it into the offer or walk.
What are the biggest IT red flags in a PE acquisition?
Five appear in almost every deal that goes sideways. Founder-owned source code with no documentation. Database architecture that holds at today's volume and fails at 2x. Manual reporting processes presented as automation. Core vendors on month-to-month contracts. Cybersecurity controls that exist on paper but have never been tested. Preside flags each one with a dollar estimate to fix, so the deal team knows what the working-capital adjustment should look like.
What does the 100-day plan look like after a PE close?
Days 1 to 30 establish the baseline. Risk in dollars, vendor inventory, application portfolio, organization map. Days 31 to 60 stand up governance and run quick-win pilots: vendor renegotiations, SaaS consolidation, license rightsizing. Days 61 to 100 lock in the recurring routines, the board reporting cadence, and the year-one value-creation plan. Preside ships all three phases as a single engagement.

Where this initiative fits into the wider Preside view
Inside the broader program
When the initiative becomes the standing engagement
This Initiative is a one-time fixed-price engagement. The Technology Operating Partner relationship continues the work on a quarterly cadence at one of four Program tiers: the dashboard gets re-run, the savings get re-baselined, the architecture gets re-mapped, and the board gets the same format every meeting. Most clients begin with an Initiative like this one and decide on the tier after the deliverable lands.
