Here’s the strange part. When you evaluate a deal, the financials get taken apart line by line. The technology, which is often the actual thing you’re buying, gets a demo and a few reassuring chats. That gap is where the nasty surprises live. The platform that can’t scale. The technical debt that eats the roadmap. The “AI” that turns out to be people typing fast. The team that walks once the founders cash out.
And the stakes are not small. Across roughly 40,000 deals over 40 years, about 70 to 75% of mergers and acquisitions fail to create value, with technology integration among the top causes and inadequate due diligence cited in around 31% of the failures (Fortune). A lot of that fate is sealed before anyone signs.
So what is technical due diligence actually for?
One thing: to tell you whether the technology can deliver the business case you’re underwriting, and what it’ll really cost and risk to get there. Not “does the demo work.” More like “will this hold up, scale, and keep its value once we own it?”
What investors miss most. It’s rarely the obvious stuff. It’s these five.
-
Scalability reality. A product that runs fine for today’s users might need a serious rebuild to handle the growth your valuation assumes. That rebuild is real money and real time, and the model almost never budgets for it.
-
Technical debt. Under deadline pressure, shortcuts pile up. Heavy debt makes every future feature slow and expensive, which throttles the exact growth you’re paying for. You can’t see it from the outside. Once you’re inside, it decides everything.
-
Key-person dependency. When the whole system lives in two founders’ heads, you’re buying a concentration of knowledge that can walk out the door. Real risk, and it almost never shows up in a pitch.
-
Story versus substance. “AI-powered.” “Fully automated.” “Enterprise-ready.” Diligence is where you find out if those words are architecture or aspiration. Sometimes the magic is just people behind a curtain.
-
Security and compliance exposure. Weak security or PDPL gaps don’t stay the seller’s problem. You inherit them, and they surface at the worst possible moment.
Think of it as a risk map, not a pass or fail.
Good diligence looks across five areas at once and grades each one honestly. Picture it as a map: solid ground here, soft ground there, and one bridge that has to hold, the link between the technology and the business case you’re buying.

Each box on that map gets a verdict. What’s solid, what’s concerning, what it’ll cost to fix, and how that should shape the deal. The output isn’t a thumbs up or down. It’s a clear-eyed read of what you’re backing, written so a board can act on it.
Committing capital to a technology business? SDCG runs independent technical due diligence. Architecture, code, team, security, and the gap between story and substance, so you know exactly what you’re backing before you sign. We don’t resell the technology and we don’t take a finder’s fee on the deal, so the only thing we’re grading is the risk. Book a free 30-minute review.
