# Platform Company

A platform company is the first business a private equity firm buys in a sector. It is chosen to be the base for later add-on acquisitions.

A platform company is the anchor of a buy-and-build plan. The investor buys it first, backs its leaders and builds the systems that a larger company needs. Later purchases attach to it.

For example, an investor wants to build a regional inspection services business. It buys a strong $8 million EBITDA company with good managers. That company becomes the platform. Smaller inspection firms then join it one at a time.

Platforms matter because they set the tone. The management team, systems and culture of the platform shape every later deal. A good platform has solid leaders, steady customers and room to grow.

Capstreet publishes "50+ Platform Acquisitions" and a Capvalue Framework® stage called "Build Scalable Platform". The platform comes first and the [add-on acquisitions](https://capstreet.multisites.ai/glossary/add-on-acquisition) follow. If you run a company like this, learn how the model works in [buy and build strategy](https://capstreet.multisites.ai/buy-and-build-strategy).
