How is buying an early-stage SaaS startup different from buying an established one?

Two SaaS products can look alike on a demo screen and be very different purchases. One has been running for years with a stable customer base and a team. The other launched recently, was built by one or two people, and has a handful of paying accounts. The questions you ask, and how much you can trust the answers, change with the stage.

What you can verify in a young product

Not much of the story is written yet. A short history means you cannot see how customers behave over a full cycle, or whether early users stay once the novelty fades. Ask for every customer’s sign-up date, plan and status, and talk to a few users if the seller agrees. Treat any projection as the seller’s opinion, not a record.

Founder-built code and few contracts

In a startup, the code often lives in the founder’s head as much as in the repository. Ask for documentation, a test of whether someone else can build and run it, and proof of who wrote each part, including contractors. With few contracts, terms may be informal or on standard online click-through terms. Your lawyer can say what the customers actually agreed to.

What changes in an established business

An older product has more evidence but more to carry over: staff, vendor contracts, support commitments, customer data and perhaps escrow or security promises. The handover is about continuity of people and process. In both cases, agree how long the seller stays to help, and what they are paid for that time.
