A Plain Guide for Owners A platform company is the first business a private equity firm buys in a sector. It is sized and staffed to be the base for later purchases. Smaller businesses bought afterward are add-ons that merge into the platform. Owners can sell as either one, and the role changes the deal. GrowthPublished November 10, 20264 min read ![Capstreet team members at Houston Reads Day](https://capstreet.multisites.ai/_astro/houston-reads-day.DxNd9bIr_Z23gxjt.webp) You may hear a buyer say “we see you as a platform” or “we see you as an add-on.” The two words sound alike, but they lead to very different deals. Here is what each one means and what it means for you. ## What is a platform company? A platform company is the first acquisition a private equity firm makes in a sector. It serves as the base for more purchases. BD Emerson defines it this way: “A platform is the first acquisition in a sector, sized and staffed to be the base for the others.” Think of it as the foundation. The firm buys a company with a strong team and systems, then adds other companies to it over time. The strategy is called [buy and build](https://capstreet.multisites.ai/glossary/buy-and-build). Our page on [buy and build strategy](https://capstreet.multisites.ai/buy-and-build-strategy) explains it in full. ## What is an add-on acquisition? An add-on is any business bought after the platform and merged into it. BD Emerson says, “An add-on is any later acquisition merged into the platform.” The glossary entry on [add-on acquisition](https://capstreet.multisites.ai/glossary/add-on-acquisition) gives the short version. Add-ons bring something the platform lacks: more customers, a new region, a new skill or a new product. Moonfare reports that “According to a Bain & Company report, add-ons made up 72% of all North American buyouts in 2022 by deal count.” So most deals you read about are add-ons. ## How do a platform and an add-on differ? A platform is the base with the team and systems, and an add-on is a smaller piece that plugs in. This table follows BD Emerson’s comparison. The tuck-in and bolt-on labels are BD Emerson’s. Question Platform Add-on Role in the plan Base for the strategy, with the team and systems others plug into Adds earnings, geography, customers or capabilities Integration Builds the playbook and absorbs each add-on Moves onto platform finance, payroll and IT on a set timeline Buyer’s review Full scope Scaled to size and risk Brand Stays the base of the group A tuck-in disappears into the platform; a bolt-on may keep its brand or product line Valuation dynamic Bought and sold at the larger company’s multiple Usually bought at a lower multiple that the exit can re-rate Details vary by deal, so never assume. Ask the buyer how it plans to run your company after the sale. ## What makes a company a good platform? A good platform has leaders, systems and a market with room to grow. BD Emerson writes that “A good platform has more management depth than its size requires.” That means the company needs a finance lead who can handle many entities and a head of people operations who can bring in new employees, not just a strong CEO. BD Emerson adds two more tests: 1. **Systems.** The accounting, payroll and customer software must take on several more companies without a rebuild. 2. **Market.** The strategy works in fragmented markets, where many owner-operated companies of similar size serve similar customers. Our glossary entry on [fragmented industry](https://capstreet.multisites.ai/glossary/fragmented-industry) explains why. Axial gives owners a related tip: “if your company operates in a fragmented industry, you can demonstrate growth potential by highlighting the opportunity for future bolt-on acquisitions.” Showing that your company could anchor a group of smaller firms can make it more attractive to a buyer. If you are asking whether your own company could be a platform, read [is your company ready for private equity](https://capstreet.multisites.ai/insights/is-your-company-ready-for-private-equity) and [why private equity wants a team that runs without you](https://capstreet.multisites.ai/insights/why-private-equity-wants-a-team-that-runs-without-you). ## How does Capstreet use platforms and add-ons? Capstreet publishes “50+ Platform Acquisitions” and “200+ Add-on Acquisitions.” Its Capvalue Framework® has three stages: Research, Build Scalable Platform and Drive Business Transformation. Under the third stage, the firm lists “Execute buy and build strategy.” You can read how the framework works on our [Capvalue Framework®](https://capstreet.multisites.ai/building-greatness) page. One Capstreet case shows the idea. In the GHX case, the firm reports it “Completed and successfully integrated 9 add-on acquisitions.” Read the [GHX case](https://capstreet.multisites.ai/cases/ghx) for the full account. ## What should an owner ask before selling as a platform or an add-on? Ask how the buyer will treat your people, your brand and your role. A platform sale and an add-on sale differ most in these areas. 1. Will my team keep its jobs and its brand? 2. Will my systems move onto the buyer’s systems, and when? 3. Do I roll over equity, and in which company? 4. Who leads after the sale? 5. What does the buyer plan to buy next? Rollover is worth special care. Our post on [what is rollover equity](https://capstreet.multisites.ai/insights/what-is-rollover-equity) explains how it works. For more questions, see [questions to ask a private equity firm before an LOI](https://capstreet.multisites.ai/insights/questions-to-ask-a-private-equity-firm-before-an-loi). If you own a smaller firm in a fragmented field, an add-on path may suit you, and a platform you join can offer scale you could not build alone. Terms, valuation and roles vary by deal. The words matter less than the plan behind them. A buyer who calls you a platform expects to add companies to yours and to lean on your leaders to do it. A buyer who calls you an add-on expects your company to join a group that already has its base. Ask which role the buyer has in mind in your first meeting, because the answer shapes your role, your equity and your team. ## Next step Review our [deal criteria](https://capstreet.multisites.ai/deal-criteria) to see what Capstreet looks for.

A platform is the first acquisition in a sector, built to be the base for others. An add-on is any later acquisition merged into the platform. A platform brings the team and systems. An add-on brings earnings, customers, geography or skills. ### Can a small company sell to a platform? Yes. Add-ons are often smaller than the platform they join. Moonfare reports that add-ons made up 72% of all North American buyouts in 2022 by deal count, citing Bain & Company. Many owners reach a buyer this way. ### Does selling to a platform mean my company disappears? It can. BD Emerson notes that a small add-on may disappear fully into the platform's operations, while others keep a brand or product line and share the back office. Ask the buyer which path it plans, and get the answer in writing. ### How does Capstreet describe its platform work? Capstreet publishes "50+ Platform Acquisitions" and "200+ Add-on Acquisitions." Its Capvalue Framework® includes the step "Execute buy and build strategy." Terms for any one deal are set in talks with the owner. ## Terms on this page - [Fragmented Industry](https://capstreet.multisites.ai/glossary/fragmented-industry) - [Add-On Acquisition](https://capstreet.multisites.ai/glossary/add-on-acquisition) - [Platform Company](https://capstreet.multisites.ai/glossary/platform-company) - [Rollover Equity](https://capstreet.multisites.ai/glossary/rollover-equity) - [Private Equity](https://capstreet.multisites.ai/glossary/private-equity) - [Buy and Build](https://capstreet.multisites.ai/glossary/buy-and-build) ## Sources 1.
