The 90 days after a deal closes determine the next five years. Systems that don't talk to each other. Processes that live in people's heads. Data in formats nobody else uses. Controls needed without disrupting the revenue that justified the acquisition.
Most PE firms accept this as the cost of integration. It is not. It is a preventable, quantifiable, fixable problem — and it has been costing PE portfolios between $6M and $9M per acquisition in recoverable waste.
Every acquired company runs different systems. Nothing talks to each other. The PE firm cannot see across the portfolio.
The processes that make the business work live in people's heads. Key people leave post-acquisition. The knowledge goes with them.
Each portfolio company builds and changes differently. No standards. No gates. No way to compare discipline across the portfolio.
The 90-day post-close system. Maps, normalizes, integrates, documents, and installs controls at every acquired company before institutional knowledge disappears.
A command center across your entire portfolio. Agents monitor every stage. Exceptions surface automatically. Your operating partners spend time on decisions — not status updates.
Every portfolio company executing projects through the same gates. Same discipline. Same data. Lessons learned feeding back into every future engagement across the portfolio.
These are not projections. They are calculated from 30 years of published research from PMI, McKinsey, the Standish Group, and Oxford University. Every number on this page is citable.
Acquisition Integration delivers full visibility into the acquired company before the 90-day integration window closes. The PE command center can see it. The operating partner can act on it. No waiting six months to find out what was actually there.
PMO Intelligence surfaces exceptions automatically. When something needs a human decision, it surfaces. When everything is running on track, it stays out of the way. The dashboard is never wrong because the data is live.
Portfolio SDLC gates eliminate the rework cycle that consumes 28% of every project budget. Requirements defined once. Technical design approved. Built. Tested. Shipped. The rework loop is designed out of the process.
SOP documentation captures every critical process before the post-acquisition attrition wave. The process is in the system, not in a person. When someone leaves, the business keeps running.
A portfolio company with documented, repeatable, auditable project execution is worth more at exit. Clean data room. Documented systems. Trained staff. Buyers pay for certainty. LeanStream builds that certainty from day one.
No renewal negotiations. No seat fee math. No vendor lock-in at contract time. The system runs without LeanStream. We are available when you call — not because you have to call, but because you want to.
Every enterprise system I built over 28 years in financial services, insurance, and manufacturing had the same root cause beneath the surface problems — no repeatable operating system. Teams improvised. Knowledge walked out. Integration chaos consumed the gains the acquisition was supposed to create. LeanStream is the system I wish existed every time. Fixed-bid. Defined outcomes. No surprises.

That is not a marketing claim. That is the operating doctrine. Build it right. Use it yourself. Then share it.
