Three diligences. Only one looks forward.
Financial due diligence tells you what the business has earned.
Legal due diligence tells you what the business has signed up to.
Technical due diligence tells you whether the business can deliver the growth you're paying for.
Every digital business runs on technology that has to scale, stay secure, keep good engineers, and carry tomorrow's demand. The risks that matter most, quiet technical debt, an architecture near its limits, AI that is more pitch than product, a team running past its depth, never appear in a P&L. They surface after closing: slipped roadmaps, emergency rewrites, security incidents, a valuation that erodes quarter by quarter. We find them earlier, while they are still leverage at the table, not losses on the books.
The insurance policy on the asset that carries your multiple.
In a modern deal, technology holds the biggest share of enterprise value, and the diligence costs a fraction of the cheque it protects. What that cover buys you:
Validate risk exposure.
Identify hidden technology risks before they impact returns.
Validate sustainability of growth.
Verify technical claims and execution capacity with evidence.
Validate valuation metrics.
Strengthen technology value, reduce uncertainty, increase confidence.
Behind all three: an impartial, objective technical opinion, based strictly on the facts given to us. The decision stays yours.
What we do
Technology Due Diligence
A full, independent inspection of a company's technology before you invest, the building survey before you buy the building. Basic or Full depth, matched to the deal.
How it works for investors →Investment Readiness
The same assessment your investors will run, done first, for you. Gaps found early, a remediation plan, and a data room that's ready before they ask.
How it works for startups →Technical Audit
A periodic health check of your own technology: what's solid, what's at risk, and what it will take to fix, with a roadmap your team can execute.
How it works for businesses →Tech Deep Dives
One specific concern, AI claims, security, code quality, cloud cost, answered thoroughly, without commissioning a full diligence.
See the deep dive modules →A structured process. Under a month, start to finish.
Most engagements complete in 2–3 weeks of active assessment, under a month from kickoff to final report when information flows on time.

What is technical due diligence?
What is technical due diligence?
Technical due diligence is an independent assessment of a company's technology, engineering team and roadmap before an investment, acquisition or major decision. Unlike financial or legal diligence, it tells you whether the business can deliver the growth you're paying for — surfacing risks such as technical debt, architecture limits, security exposure, unsubstantiated AI claims and key-person dependency.
How long does a technical due diligence take?
Most engagements complete in 2–3 weeks of active assessment, and under a month from kickoff to final report when information flows on time. A Basic Tech DD screen can move faster, in about 5–7 business days.
Who does Techstack Authority work with?
TSA works with venture capital, private equity, family offices and corporate acquirers evaluating deals; startups preparing to raise or exit; and businesses that want an independent health check of their own technology.
How does Techstack Authority protect confidentiality?
Findings belong solely to whoever commissioned them. TSA works NDA-first with read-only access and need-to-know staffing; no other party — including the other side of a deal — receives the report, a summary, or even confirmation that an engagement took place.
