Start with the reachable market, not the headline market
The total market is usually too large to be useful. The important question is how much of that market is realistically reachable in year 1 or year 2 through your actual sales motion. For B2B teams, that means thinking about territory, channel access, procurement cycle, and the credibility gap that comes with being a new entrant.
Checklist items that matter
- Define the target segment and the reachable addressable market.
- Map the top competitors and the switching costs for customers.
- Identify customer adoption barriers, including trust, pricing, and integration.
- Review distribution assumptions and whether partners can actually carry the load.
- Check launch timing against regulatory, operational, and hiring constraints.
Why competitor analysis is not optional
Many market entries fail because the team sizes demand but ignores the competitive response. Competitors can reduce price, increase spend, or lock up distribution before the new entrant has traction. A strong plan addresses not just who is in the market, but how those firms will react if you start taking share.
What to prove before launch
Before launch, prove that the market is reachable, the customer has a reason to switch, the sales motion is real, and the economics work at a smaller scale. If any of those assumptions fail, the plan needs another pass.
