IT due diligence that keeps pace with the deal.
IT due diligence examines the systems a target business actually runs on, infrastructure, security, licences, people and spend, before the deal closes. StackUp gives acquirers an independent, documented IT baseline within 48 hours from under 30 minutes of the target's time, so integration surprises surface in diligence, not in month three.

The checklist
What IT due diligence reviews before you buy
The IT estate is where acquisition surprises hide in plain sight: unsupported systems, licence debt and key-person dependencies that only surface when integration starts.
Infrastructure, licences and the true cost of IT
What is the estate actually made of, and what does it really cost to run? StackUp scores infrastructure resilience, cloud and network posture, licence and vendor exposure, and benchmarks IT spend against peers, so the deal model reflects the IT you are actually buying.
People, process and integration risk
Systems integrate; teams and processes decide whether it works. StackUp assesses key-person risk, documentation, policies and operational maturity, the factors that set your integration timeline. It is the IT-focused lane of a broader tech due diligence, and pairs with cybersecurity due diligence where security carries the deal risk.
How it works
Three steps to IT clarity at deal speed
Assess
The target's leadership answers, once.
- Structured assessment, under 30 minutes to complete
- No workshops and no site visits required
- Covers all eight technology areas including IT operations
Understand
An independent baseline, documented.
- Evidence-based scoring benchmarked against peers
- Integration risks sized in dollars
- Shareable with advisors, partners and the board
Decide
Deal terms informed by IT reality.
- A defensible risk view that can inform valuation
- Day-one integration priorities already mapped
- Re-run post-close to track the fix
Why StackUp
IT diligence at deal speed, not audit speed
A consistent, independent standard for every target's IT estate, used by leading PE firms to standardise diligence.
A traditional IT audit approach
- Weeks of site visits and stakeholder interviews
- Findings written for IT teams, not deal teams
- A different methodology on every deal
- Costs that force triage on smaller deals
StackUp
- A documented IT baseline within 48 hours
- Findings in dollars and plain language
- The same standard across every target
- Priced so every deal gets diligence, not just the big ones
Reviews
What acquirers and deal teams say
Investors and operators on getting IT clarity before the ink dries.
Not only saved us significant effort and costs but also ensured we had the insights needed to confidently move forward in our deal process.
Comprehensive and fast.
Enabled us to approach future investment discussions with confidence.
Proof
IT baselines that de-risked the deal
Real engagements where a documented IT view arrived early enough to matter.
Investor accelerates technology due diligence without cutting corners
Acquiring a consumer goods business with a 35-person tech team and $3.2M annual tech spend, this PE investor had a documented IT baseline within 24 hours of deploying StackUp.
"We didn't want to replace our advisors. We just didn't want to spend three weeks figuring out what existed before we could talk about what actually mattered."
Board secures independent technology oversight before it becomes urgent
A services business board used the same assessment to evidence IT oversight, the baseline that serves diligence also serves governance after close.
"This gave us evidence without turning it into a six-month audit exercise."
FAQs
IT Due Diligence questions, answered
What is IT due diligence?
IT due diligence is the review of a target company's information technology before an acquisition or investment: infrastructure, applications, licences, security, IT team and spend. Its job is to establish what the IT estate really is, what it costs, what risks it carries, and what integration will take, before those answers can affect the price.
How is IT due diligence different from tech due diligence?
IT due diligence focuses on the operational estate, infrastructure, systems, licences, support and IT operations. Tech due diligence is broader, covering product technology, engineering capability and architecture as well. In an M&A context you often need both lenses; StackUp scores the full technology function so one assessment serves either framing.
What should an IT due diligence checklist cover?
At minimum: infrastructure and hosting, application inventory and supportability, licence compliance, security and data protection, backup and recovery, key-person dependencies, IT policies, vendor contracts and change-of-control clauses, and total IT spend versus peers. StackUp structures all of this into eight scored areas with a dollar figure on each gap.
How fast can IT due diligence be done?
With StackUp, the target's technology leadership completes a structured assessment in under 30 minutes, and acquirers have a documented, independent baseline within 48 hours, in one PE engagement, within 24. Traditional IT audits take weeks, which is exactly why IT findings so often arrive too late to affect terms.
Can we use the assessment after the deal closes?
Yes, that is where much of the value compounds. The same baseline becomes the integration roadmap: prioritised actions, owners and tracking, plus portfolio-level visibility if you hold multiple companies. Re-running the assessment shows the board measurable post-close progress.
