Tech due diligence is the structured review of a company's technology, architecture, security, team and spend, before you invest or acquire. StackUp compresses the discovery phase from three weeks to 48 hours: the target's leadership completes a structured assessment in under 30 minutes, and you get an independent, evidence-based baseline your advisors can build on.

What it covers
Most deal surprises are not exotic. They are ordinary weaknesses, key-person risk, unmanaged spend, soft security, that nobody scored before the price was set.
StackUp assesses the target across the same eight pillars an experienced CTO would probe, from data security and vendor exposure to the resilience of the team itself, and benchmarks each one against best practice and peers, so risk is measured, not asserted.
StackUp does not replace your DD advisors, it hands them a documented baseline in 48 hours so their expensive hours go into high-value analysis, not discovery. For deal-specific depth, pair it with software due diligence on the product and cybersecurity due diligence on the security posture.

Investors and executives on running diligence with an independent, evidence-first platform.
Not only saved us significant effort and costs but also ensured we had the insights needed to confidently move forward in our deal process.
Enabled us to approach future investment discussions with confidence.
Comprehensive and fast.
Proof
Real engagements where an independent technology baseline changed the pace, and the confidence, of the decision.
A mid-market PE investor acquiring a $180M revenue business had an eight-week diligence window. StackUp compressed the three-to-four-week discovery phase to 48 hours, letting their advisors focus on high-value analysis.
"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."
A board used the same independent assessment to evidence technology oversight, proof that the baseline holds up outside the deal room too.
"This gave us evidence without turning it into a six-month audit exercise."
FAQs
Tech due diligence is the structured review of a company's technology function before an investment, acquisition or major partnership. It examines architecture, security, team, processes, vendors and spend to establish whether the technology can support the business case, and what risks should be priced into the deal.
A traditional process runs three to four weeks of discovery before analysis even starts. With StackUp, the target's leadership completes a structured assessment in under 30 minutes and investors have a documented, independent baseline within 48 hours, one PE investor compressed exactly that discovery phase inside an eight-week deal window.
Advisory-led DD commonly runs to six figures on mid-market deals, with much of it spent establishing baseline facts. StackUp delivers the baseline at a fraction of that cost, with a money-back guarantee, so advisory spend goes into judgement, not discovery. See StackUp's pricing page for current plans.
No. StackUp gives you an independent, consistent baseline of the target's technology function; your advisors then focus their hours on the high-value, deal-specific analysis. In one engagement, that division of labour meant the investor's advisors started from a documented baseline instead of three weeks of discovery interviews.
Key-person risk on core systems, untested backups and recovery, security posture below what the deal assumes, unmanaged cloud and licence spend, and vendor contracts that don't survive a change of control. For deals where the product itself is the asset, run dedicated software due diligence as well.
