Technical due diligence
An in-progress rebuild running alongside the system it's replacing is still a live risk
A travel-industry booking and reservations platform whose core booking and transaction engine predates modern cloud-native architecture by well over a decade — with an in-progress infrastructure rebuild still running alongside the legacy production system it's meant to replace. Technical due diligence: $10,000–$25,000, one to three weeks.
What we find
The core booking and transaction engine predates modern cloud-native architecture by well over a decade, and it's still the system of record in production. There's an infrastructure rebuild in progress — so the company knows the core needs replacing — but that rebuild is running alongside the legacy system rather than having already replaced it, which is exactly the phase where a rebuild is most likely to stall, run over budget, or quietly become permanent scaffolding instead of a finished migration.
Why it matters for a PE holder
An in-flight rebuild is neither a green flag nor a red one on its own — it's a question mark that needs a real answer before close. A buyer needs to know how much of current revenue still depends on the pre-cloud-native core, how far along the rebuild actually is against what the team believes, and what happens to the deal model if the rebuild takes another year, or two, or never fully finishes and the legacy system just keeps getting maintained alongside it indefinitely.
What the engagement checks
The diligence engagement sizes how much of the business still depends on the pre-cloud-native core, and prices the cost and risk of finishing or retiring the in-flight rebuild before close — turning "we're modernizing" into a number the deal model can actually use.
$10,000–$25,000, one to three weeks. We read what a target company's codebase, dependencies and infrastructure actually run, find the specific legacy-stack or security exposure it carries, and hand back a report scoped enough to become the remediation plan — if the deal proceeds and one is warranted.
This pattern is drawn from public research on a real, small software company, not a completed Shashtram engagement. Named engagements with measured figures replace it as clients clear being named.
One pattern, not the whole offer
This is one pattern. The full technical due diligence offer covers pricing, what the report contains, and answers to the questions PE operating partners actually ask.
Diligence is Map, scoped to one question and priced on its own — not a separate product, and never an assumed rewrite.
Questions
Straight answers.
What if we don't proceed to a rebuild after the report?
Then the report is what you paid for, and the engagement ends there. Nothing about the diligence commits you to a modernization project — most of the value in a $10,000–$25,000 read is knowing what you're actually buying, whether or not you act on it afterward.
