When the Data Room Is Thin: How Expert-Led Interviews Surface IT Risk Before You Sign

Every technology diligence runs into the same wall: the data isn't there. Timelines are short, the data room is thin, and the systems that matter most are the least documented — an application inventory that is out of date, an architecture diagram nobody has touched since the last migration, security controls that exist in practice but not on paper. Waiting for better data usually means signing without it.

The answer is to stop treating documents as the primary source and go to the people who hold the knowledge. Expert-led interviews with the target's IT leaders — application owners, enterprise and domain architects, security, infrastructure, and service operations — surface what no data room contains: where the technical debt actually sits, which controls are real, which systems depend on one person, and which vendor contracts are quietly constraining the roadmap. The questions are broad enough to cover the whole estate yet specific enough for a lead to answer in an hour, so the burden on the target stays small. Of the roughly 110 hypotheses we test, more than 90% can be validated directly by those leaders, which sharply reduces the dependency on quality data being available at all — the remainder is tested with the documentation and logs that Altamount obtains in collaboration with the target's IT team.

The value comes from tying every finding back to the deal thesis. We assess five lenses and read each for what it means for the investment case: applications and data for technical debt and its effect on EBITDA, infrastructure and security for IT risk and one-time remediation cost, architecture for whether the platform can support the growth plan, and the IT operating model and operations for the synergies the thesis assumes. Findings are sorted into three groups a deal team can act on — issues already realized, risks that could emerge post-close, and watchlist items that are healthy today but need monitoring.

For sponsors, the practical result is a Red Flag Report around week three and a Value Creation Roadmap by week five, so the cost of the fixes is priced into the deal before signing rather than discovered after it. It also changes the conversation with the seller: a finding backed by named interviews and a quantified cost is far harder to dismiss than a generic concern raised late in the process.
