Build or Buy? What Founders Should Check Before Acquiring a Small Online Business

The Question Behind Every Listing

You've got savings, a spreadsheet of side-project ideas and a nagging feeling that the first eighteen months of any startup are mostly spent finding out nobody wants the thing. Then you open a marketplace and see a small, profitable SaaS tool with paying customers, listed at a price that looks almost reasonable. Should you build, or buy?

It's a fair question, and in September Acquire.com put some useful numbers around it. In a webinar recap published on its blog on 4 September 2026, founder and CEO Andrew Gazdecki and M&A advisor Rainier Nanquil laid out what they're seeing on the marketplace. Their pitch for buying is simple: an acquisition can start with a product, customers and evidence of demand already in place, which suits operators who are better at taking something from one to ten than from zero to one.

That's true. It's also what a marketplace would say. So let's look at the numbers and then at what you should actually check.

What Acquire.com Is Seeing

According to the recap, SaaS businesses are commonly trading at around 3–5x profit or 1–3x revenue, while agencies sit nearer 1–3x profit or 1–2x revenue. Acquire.com's January 2026 multiples report, based on its own confirmed transactions, put the median SaaS profit multiple at 3.9x in both 2024 and 2025. The webinar also said the market appears to have bottomed around 2024 and has been steadier since.

Two other figures caught my eye. Pricing a listing 20% above fair market value corresponded with roughly 2% serious buyer interest in their data, against about 92% when priced 20% below. And AI-related businesses made up 10.5% of submissions, up from 4.6% in the prior twelve months.

Keep the source in mind. These are one marketplace's observations about its own deals, mostly small software and online businesses. They're useful. They aren't a law of nature, and they won't tell you what a specific business is worth.

When Buying Beats Building

Buying makes the most sense when your edge is distribution, operations or sales rather than invention. If you know how to sell into dentists but have no interest in figuring out what dentists want from scratch, an existing tool with forty dental clinics on it is a shortcut worth paying for.

Building still wins when the thing you want doesn't exist, when you'd rewrite most of an acquired codebase anyway, or when the listing's customers aren't the customers you want. Paying 4x profit for a business you'll gut in six months is an expensive way to buy a domain and a mailing list.

My honest view: most first-time buyers underestimate how much of a small business lives in the founder's head. That's where the checklist below earns its keep.

The Pre-Offer Checklist

Two extras. First, read the deal structure as carefully as the price. The recap notes that seller financing, earnouts and equity rollovers are common ways to bridge a gap, and an earnout tied to vague targets is a future argument. Second, pay attention to AI claims. If a listing says AI cut its costs, ask for the before-and-after numbers.

Don't Forget the Name

Small acquisitions often come with weak brands: a product named after a feature, or a domain with a hyphen and a number in it. Some buyers keep the business and rebrand it. That's a legitimate play, and it separates two decisions people tend to blur: buying cash flow and choosing an identity. If you're weighing a SaaS or developer-tools brand, the B2B SaaS concept on the RogueGhost homepage shows how a single name can be pitched across several product directions.

None of the marketplace multiples above apply to a domain name on its own, by the way. A name without revenue is priced on different logic entirely.

Closing & Sources

Buying isn't a cheat code. It swaps the risk of finding product-market fit for the risk of inheriting someone else's shortcuts. If the revenue checks out, the customers are spread out and the owner's job can be written down on a page or two, the maths often favours buying. If not, building might be the cheaper mistake.
