Most M&A horror stories — failed integrations, surprise tech debt, six-month outages — come from skipping or rushing technical diligence. We deliver a structured 2-week technical assessment of the target: stack, team, contracts, risks, and what real integration will cost.
Discovered post-close. Modernization cost wipes out the deal's projected synergies.
Bus factor of one. They quit during integration. No documentation. Years of work to reconstruct.
Target had no MFA, no EDR, no SOC. Acquirer's insurance won't cover the combined entity until you fix it. 90 days, no coverage.
Target locked in to a 5-year ERP contract three months before close. $400k/year you can't reduce.
Every system, every cloud account, every SaaS app. Modern vs. legacy. Maintained vs. abandoned. Documented vs. tribal knowledge.
Senior strength. Key-person risk. Cultural fit. Retention concerns. Documented.
Identity, endpoints, network, cloud. Critical findings called out. Insurance implications flagged.
Every major tech contract, renewal date, exit options. Total cost of ownership reconciled.
What it costs to bring the target onto acquirer infrastructure: hours, dollars, calendar months, risk.
Board-ready report. Verbal walkthrough with the deal team and acquirer leadership.
Diligence team formed. Read-only access to target's systems requested. NDA in place.
Interviews with target's CTO, IT, and key engineers. Stack inventory. Contract review.
Assess each finding for materiality and risk. Build integration cost model. Identify deal-breakers if any.
Written report finalized. Verbal walkthrough with acquirer leadership. Q&A session.
Q&A follow-ups answered. Findings handed off to integration team.
Choose based on deal size and risk tolerance.
| Light (1 week) | Standard (2 weeks) | Deep (4 weeks) | |
|---|---|---|---|
| Stack inventory | Yes | Yes | Yes + dependency mapping |
| Team interviews | CTO only | CTO + 3 leads | CTO + 8+ engineers |
| Security posture | High-level | Posture scan | Full audit |
| Contract review | Top 10 | All material | All material + legal sync |
| Integration cost model | Range estimate | Costed plan | Quarterly-bucketed plan |
| Typical fee | $20–35k | $45–90k | $120–200k |
From kickoff to written report. Reliable across deal sizes.
Of diligence engagements delivered within commitment window.
Of engagements where findings caused acquirer to renegotiate price. Pays for the engagement many times over.
On our diligence — clients have never discovered a major issue post-close that we missed pre-close.
“We were ready to close on a $40M acquisition. Senator's diligence found three issues we hadn't surfaced — including a $2.5M integration cost we'd missed. Renegotiated the price, the deal still closed, and we avoided buying a problem.”
Most engagements start within 5 business days of kickoff. We hold capacity for active deals.
Yes — many clients move from diligence into integration. Same team. Continuity is helpful.
We work with what we can access. The report flags what we couldn't verify. Limited access is itself a finding.
Yes — and we operate with information barriers between deal teams. Standard practice.
