B2B SaaS Validation
How to Validate a B2B SaaS Startup Idea
B2B founders build for the user. But the user isn't the buyer, and the buyer doesn't care about your features.
The most common b2b saas mistake
Building features for months based on conversations with users who said 'I'd definitely use this' but have zero purchasing power. Always ask: who signs the check?
5 assumptions every b2b saas founder should test
Budget authority
Your target user can actually approve and pay for your tool.
The question that exposes it:
“When you find a new tool you want for work, what's the approval process? Can you buy it yourself?”
Workflow integration
Your product fits into existing tools and processes without forcing a rip-and-replace.
The question that exposes it:
“What tools does your team currently use for [problem]? How painful would it be to add another tool?”
Willingness to pay vs build
Companies will buy your solution instead of building it internally or using a spreadsheet.
The question that exposes it:
“Is your team currently solving this problem with spreadsheets, manual processes, or an internal tool?”
Champion risk
Someone inside the org will stake their reputation on recommending your tool.
The question that exposes it:
“Have you ever championed a new tool at work? What happened?”
Multi-seat expansion
After one person adopts, the rest of the team will too.
The question that exposes it:
“When one person on your team starts using a new tool, does the rest of the team typically follow? Why or why not?”
What happens when you test first
A B2B SaaS founder who tests budget authority and workflow integration first can target the buyer persona with the shortest sales cycle — instead of spending 6 months in enterprise sales purgatory.
