M&A Tech Due Diligence: Read the Code, Not the Pitch
A scoped diligence engagement — findings you can put in the deal model.
M&A tech due diligence usually runs on interviews and slideware. Swimm runs it on the code: a delivered assessment covering the tech stack, dependencies, dead code, risks, and modernization fit — evidence a deal team can act on. Swimm is a product-enabled service company. We combine deterministic analysis for accuracy, AI for scale, and SMEs to catch what tools miss.
The problem
Technical debt shows up after the deal closes
By the time technical debt shows up in the numbers, the deal is already closed.
01
Management presentations hide technical debt. A slide about "modern architecture" isn't evidence — and it's rarely written by the engineers who'd tell you the truth.
02
Integration cost surprises surface post-close. The real cost of untangling a target's codebase usually shows up after the deal is signed, not before.
03
Key-person risk is invisible in interviews. A confident answer in a management interview doesn't tell you whether that knowledge exists anywhere else.
04
Diligence windows are short, codebases aren't. You have days to assess a system that took years to build — manual review can't cover it.
How it works
Assessment is the diligence engine
01 · Assessment
A diligence-sized snapshot
A snapshot of the target's tech stack and modernization fit, along with a scoped plan, risks, and success criteria — sized to fit a diligence window.
02 · Deterministic
The whole system, mapped
Deterministic analysis maps dependencies, entry points, dead code, and cross-repo relationships across the target's codebase.
03 · SME
Findings interpreted for the deal
SMEs interpret those findings for deal context, translating technical facts into implications for valuation and integration.

Frequently asked questions
Is Swimm's tech due diligence a product or a service?
It’s a scoped engagement, not software the deal team installs — Swimm’s analysts and engine do the work, and you receive a deliverable.
What does M&A tech due diligence with Swimm cover?
A stack snapshot, dependency and dead-code analysis, identified risks, and an assessment of modernization fit — everything an Assessment engagement produces.
How is this different from a standard code review?
A code review samples opinions on parts of the codebase. Swimm’s deterministic engine maps the whole system, and SMEs interpret the findings for deal context — full coverage, not a sample.
What does the deal team receive?
A scoped assessment deliverable — risks, success criteria, and modernization plan inputs you can act on before close.
Can diligence findings carry into post-close work?
Yes — the Assessment feeds directly into Specification and Modernization if you move forward, so nothing from diligence gets thrown away after signing.
