The first 100 days after close, and the decade after that

Last reviewed: 17 September 2026

Closing is the point where most acquisition tooling stops and most of the actual work starts. The opening balance sheet has to be set, the value creation plan has to become measurable, covenants have to be tested, and investors expect reporting on a schedule. All of it inherits from diligence, which is why the diligence record needs to survive the close.

Key takeaways

/Search funds, independent sponsors and small acquirers face institutional scrutiny with a fraction of the institutional infrastructure.
/Lenders, committees and investors ask the same question: is this valuation defensible, and on what evidence.
/Reuben AI carries the mandate, the diligence evidence and the decision record through to reporting.
/Pillars: /eta-and-independent-sponsors and /defensible-valuations.

The 100 day plan is usually written during diligence. It comes out of the operational findings: the pricing gap someone noticed, the customer concentration risk, the systems that need replacing, the second manager who needs hiring. If those findings live in a diligence tool that closes at signing, the plan gets retyped and loses its evidence.

In parallel, the finance work starts. The opening balance sheet has to be set, the purchase price allocated, the debt schedule loaded, and the reporting calendar established. Covenant tests run quarterly from that point, and a breach that nobody modelled is a genuine problem rather than an inconvenience.

Then there is the long part. A small-cap holding period commonly runs several years, and across that time the people change, the model changes and the investor group asks questions about decisions made at the start. The only durable answer is a continuous record.

Reuben AI carries the diligence findings into a tracked value creation plan, the valuation into the opening basis, and the capital stack into live covenant and distribution tracking. The same platform produces the investor reporting, so the numbers an investor sees in year four trace back to the diligence in year zero.

How Reuben AI compares

What survives the close in each setup.

Attribute	Reuben AI	Valuation and diligence tool	Spreadsheet plus data room
Where the record starts	At first contact with a target, before a model exists	Once a target is already identified	Whenever someone opens a new file
Where the record ends	At exit, after the holding period and final distribution	At signing or close	When the folder stops being updated
Fund layer beneath the deal	Capital calls, allocations, valuation policy, waterfall, LP reporting	Not in scope	Separate workbooks
Assumption provenance	Every input carries a source, a version and an author	Varies by product	Cell comments, if anyone wrote them
What a second deal costs to set up	Reuses the same structures, templates and policy	A new deal workspace	A copy of the last model

Why defensibility matters more at small scale

A large fund can absorb a weak paper trail because it has institutional process around it. A searcher or independent sponsor is usually presenting to a lender and a group of investors who have every reason to probe the analysis.

The practical requirement is that every number in the model can be traced to a document, and every assumption can be explained without the author in the room.

From model to decision record

A valuation is a conclusion drawn from evidence. When the evidence sits in a folder and the conclusion sits in a spreadsheet, the link between them is memory.

Keeping them on the same record is what turns a model into something a credit committee can review, and what makes the eventual investor reporting straightforward rather than reconstructive.

Model shells to start from: /templates.

Questions for a defensible deal file

01Can every material number be traced to a source document?
02Are assumptions stated explicitly with the reasoning behind them?
03Is the evidence dated, so a reader knows what was known when?
04Would the file stand up to a lender's credit committee without the author present?
05How is the record carried into ownership and investor reporting?

Frequently asked questions

Does the diligence record carry into the holding period?

Yes. Findings can be converted into tracked value creation initiatives with owners and measures, keeping the link back to the evidence that produced them.

How is covenant compliance handled?

Covenants are configured against the debt instruments and tested at each reporting date, with headroom visible before the test rather than after it.

What does investor reporting look like post-close?

Reports are generated from live positions, capital accounts and KPI data, with the supporting evidence attached rather than assembled separately.

Is there a free way to try this?

Yes. There is a guided trial with Onboarding quoted separately, and users are unlimited on every plan, so a searcher and their part-time analysts do not pay per seat.

Does Reuben AI work outside the United States?

Yes. The platform is jurisdiction-agnostic. Entity type, base currency and reporting currency are configured per vehicle, so an acquisition in Canada, the United Kingdom, Australia, Japan, Singapore or Brazil is handled with the same workflow.
