The single most expensive mistake a new owner can make is moving too fast. The second most expensive is moving too slowly. We've watched both, sometimes in the same week, and the operators who compound value reliably are the ones who distinguish between the two reflexively.
Here's the playbook we run on every business we acquire — refined over a decade of asset management — for the first 100 days post-close.
Days 0–14: Listen more than you speak
The biggest cultural risk in a new acquisition is the new owner showing up on day one with a clipboard. Even when prior management has stayed on, even when the deal is described as "minimal disruption" in the LOI, the team is watching. They want to know whether you're going to honor what they've built or replace it.
Our rule for week one: no policy changes, no headcount changes, no compensation changes, no software changes. We sit in on every recurring meeting we can fit on the calendar. We ask three questions of every direct report and every long-tenured employee:
- What's working that you'd be devastated to lose?
- What's broken that you've been frustrated by but never had license to fix?
- What would you do in the first ninety days if it were your money?
You get more honest signal in that first fortnight than in the next six months of due diligence redux. Take notes. Don't act on any of it yet.
Days 15–45: Stakeholder map and the 30-60-90
By week three we've built a stakeholder map that goes well beyond the org chart. Key customers, key suppliers, the bank, the insurance broker, the outsourced accountant, the property landlord, the IT contractor — anyone whose decision could cause material disruption. We rank them by leverage and by relationship strength with the existing team.
The 30-60-90 plan we build at this stage is internal and intentionally narrow. We focus on three to five operational moves, ranked by reversibility. Reversible moves — pricing experiments, contract renegotiations, vendor consolidation — get scheduled first. Irreversible moves — terminations, large capex, banking changes — get pushed until we have at least one quarter of operating data.
If a decision can be reversed in 30 days at less than 5% of EBITDA, run the experiment now. If it can't, wait until the second quarter.
Days 45–75: The first real change
This is the phase that separates disciplined operators from impatient ones. By week seven we know enough to identify two or three areas where the business has been leaving money on the table — usually pricing, usually receivables, sometimes a product or service line that's been under-marketed because the prior owner didn't want to invest in growth.
We pick exactly one. We resource it generously. We give the existing team the lead on execution and ourselves the lead on measurement. Everyone needs to feel a small early win before we attempt anything ambitious.
Days 75–100: Build the operating cadence
The deliverable that matters most at day 100 isn't a strategic plan — it's a working weekly business review. A repeatable meeting, a repeatable dashboard, repeatable accountability for the small handful of metrics that drive enterprise value in this specific business.
Get that cadence right and the next several years compound. Get it wrong and you spend the next several years firefighting symptoms because nobody is watching the underlying instrument panel.
The single biggest mistake to avoid
Almost every failed acquisition we've watched failed for the same reason: the new owner mistook activity for progress. Reorganizing the org chart, replacing the ERP, rebranding the website, hiring a new VP of Sales — these are all things that feel like value creation but rarely are, especially in the first 100 days.
"The job in the first 100 days is to learn the business well enough to know what to leave alone. Everything else is a privilege you earn by being right about the first part."
Discipline isn't passivity. It's the willingness to deploy effort where it compounds — and the humility to leave alone the things that don't yet need fixing. That's how you build a business worth selling at the right number.
