Post-acquisition integration that keeps the team you paid for.
Post-acquisition technology and team integration for acquirers and PE platform companies doing add-ons. Systems, team, and product, integrated on a schedule the deal team can hold to. In 2024 I was the Mergers and Acquisitions Integration Lead at IBM for an acquired pattern-based AI company. I owned the systems, team, and product integration, and it delivered on schedule with the acquired team retained.
Systems, team, and product, in that order of urgency
The deal thesis usually depends on the product. The product depends on the team. The team decides whether to stay in the first 30 days.
Systems
Identity and access, cloud accounts, security tooling, source control, CI/CD, billing, and support. Consolidated where it pays off, bridged where it doesn't yet.
Team
Roles, reporting lines, compensation bands, and the retention conversations. Who leads, who stays, and what each person hears, from whom, and when.
Product
The roadmap merge. Overlapping features, the data and APIs that have to connect, and what the acquired customers see change and when.
Security and compliance
Bringing the add-on into the platform's security posture and, where it exists, its SOC 2 scope without a gap in coverage.
Vendors and cost
Duplicate tools, overlapping contracts, and cloud spend. Consolidation that shows up in the margin by the end of the first year.
Communication
A written plan the acquired team can read, a cadence the operating partner can follow, and no surprises for either.
The first 100 days, then the long tail
The critical path is short. Everything else runs on its own schedule with the acquired team doing most of it.
Diligence into plan
The technical due diligence findings become the integration plan: what to connect, what to consolidate, what to leave alone, and who owns each item.
People and access
Reporting lines settled, retention conversations done, identity and access connected, security posture confirmed. The acquired team hears the plan from someone who understands their system.
Roadmap and systems
The roadmap decision made and communicated. Source control, CI/CD, and tooling consolidated. Duplicate vendors cut. The first joint release shipped.
Handoff
Remaining consolidation on a schedule, a playbook for the next add-on, and a leader in place. I step back or stay fractional for oversight.
A playbook for the next add-on
- Repeatable. The first integration produces a playbook: checklists, timelines, and the decisions that recur. The second one is faster.
- A resource the operating partner can send in. Diligence before the deal, integration after it, and an interim CTO when the add-on's technical leader leaves.
- Portfolio-wide view. Shared vendors, shared security posture, and shared standards across the platform's companies.
- Written for the committee. Status the deal team can read in five minutes, and risks surfaced early instead of in the quarterly review.
Silence, surprises, and a roadmap that erases their work
Acquired engineers leave when they don't know where they stand, when decisions reach them second-hand, and when the product they built disappears from the roadmap without a conversation.
The fix is a plan they can read, a leader who understands their system, and a roadmap merge that keeps what the deal thesis depends on. That is how the IBM integration kept its team.
Post-acquisition integration questions
What does post-acquisition integration cover?
Three things: systems, team, and product. Identity, infrastructure, security, and tooling. Roles, reporting lines, and retention. Roadmap, overlapping features, and the data and APIs that have to connect. All on a schedule the deal team can hold to.
How do you keep the acquired team?
By being clear and early. The acquired engineers hear the plan from someone who understands their system. Roles and reporting lines are settled in the first 30 days. The parts of their product that matter survive the roadmap merge. At IBM in 2024, the acquired team was retained through the integration.
How long does post-acquisition integration take?
The first 100 days cover the critical path: identity and access, security, reporting lines, and the roadmap decision. Full systems consolidation depends on the stack and runs on its own schedule after that, with the acquired team doing most of it.
Do you work with PE platforms doing add-ons?
Yes. A platform doing several add-ons needs a repeatable integration playbook and a technical resource the operating partner can send in. I can build the playbook on the first add-on and run or oversee the next ones.
Can you also do the diligence before the deal?
Yes, and it's better that way. The diligence findings become the integration plan, and nothing in the first 100 days is a surprise.
What was your role at IBM?
Mergers and Acquisitions Integration Lead in 2024 for an acquired pattern-based AI company. I owned the systems, team, and product integration. It delivered on schedule with the acquired team retained.
How is post-acquisition integration engaged?
As an interim engagement, three to four days a week for a fixed term, or fractional at a lower cadence for oversight. Day rate or monthly retainer, settled in the first conversations and written into the agreement.
