Platform acquisition
The first, largest acquisition in a buy-and-build strategy, which becomes the base the sponsor grows through further acquisitions.
A platform is the company a sponsor builds around. It generally needs enough scale, management depth, and systems capability to absorb other businesses — which is why platforms attract higher multiples than the add-ons that follow, and why the management team is usually retained rather than replaced.
For a seller, being a platform is a materially different outcome from being an add-on. Your business keeps its identity and typically its leadership, you may be asked to lead the buy-and-build, and rollover equity is often central to the structure precisely because the sponsor wants you invested in the roll-up.
The realistic view of the rollover is what matters. The second bite can be substantial if the strategy works, and it is not guaranteed: acquisitions may not materialise, integration may not deliver, leverage constrains the downside, and the exit timing is the sponsor's decision, not yours. Treat it as equity risk in a leveraged company, because that is what it is.
Where sellers get caught
- Valuing the rollover on the sponsor's model rather than on a range that includes the strategy underperforming.
- Committing to lead a buy-and-build without agreeing resources, authority, and pace.
- Overlooking governance terms — board composition, reserved matters, drag rights — that decide how much say you actually keep.
Common questions
What makes a business a platform rather than an add-on?
Usually scale, a management team that can operate without the founder, and systems that can absorb other businesses. The same company can be a platform to one sponsor and an add-on to another.
Do platform sellers stay on?
Frequently, because the sponsor is buying the management capability as much as the earnings. That expectation should be explicit and documented before signing.
