The deal model assumes a value creation plan that starts on day one. In practice, most of what determines whether that plan is achievable gets decided, or defaulted, in the first hundred days after close. Technology is one of the areas most likely to get deferred past that window, and one of the most expensive to fix later if it is.
Why the First 100 Days Matter More Than the Deal Model Assumess
Early decisions set defaults that are expensive to change later. A vendor contract renewed on autopilot in month two is now locked in for a multi-year term. A security gap identified but not prioritized becomes the thing that surfaces in exit diligence three years later. The first 100 days aren't when everything gets fixed, but they're when the priority list gets set, and a technology issue that misses that list tends to wait for the next crisis to get attention.
The Short List: What Actually Needs a Decision Early
Not everything needs to happen in the first 100 days, but a few things benefit enormously from an early decision: any contract with a near-term renewal or auto-renewal clause, any security gap material enough to matter at exit, any technology dependency on the seller (relevant in a carve-out specifically, see IT Carve-Out & Divestiture Separation), and a baseline inventory of what's actually being spent on technology, since without that baseline nothing else on this list can be prioritized with any confidence.
Where Executive Advisory Fits
Many portfolio companies in this window have a capable internal IT leader who's never operated inside a PE-owned company before, or don't yet have a technology leader with the bandwidth to run this prioritization alongside everything else the first 100 days demands. An outside advisory resource, brought in specifically for this window, can help set the baseline, build the decision framework, and mentor the internal team through it rather than simply handing over a report and leaving.
A Rough 30-60-90 Shape
Most first-100-days technology plans fall into a similar rhythm even when the specifics differ. The first thirty days are about visibility: a baseline inventory of contracts, spend, and any near-term renewal or security exposure. The next thirty are about prioritization: turning that inventory into a short, ranked list with owners attached. The last thirty are about starting execution on the highest-priority items, not finishing everything, just proving the plan can move from a document into actual progress before the window closes.
Frequently Asked Questions
Who should own the first-100-days technology plan? Ideally the portfolio company's own IT or operations leader, with visibility to the sponsor's operating partner. Where that internal capability doesn't yet exist, outside advisory support can fill the gap without permanently replacing it.
What if the 100-day window has already passed?The specific defaults set in that window get harder, not impossible, to change. A later review still finds real savings and risk; it's just working against contracts and habits that have had more time to set.
What's realistic to actually finish in 100 days? Usually the baseline and the priority list, plus early progress on the one or two most urgent items. Structural fixes, a platform migration, a full security stack rebuild, typically extend well past day 100; the point of this window is making sure they're on the list, not completed.
