Assumption Type
Trust: Will Anyone Trust a Startup With Their [Money/Data/Health]?
Users will hand their credit card to Amazon without thinking. They won't hand anything to you. Yet.
What is the trust assumption?
Trust is the assumption that users will believe your product is safe, reliable, and competent enough to handle something important to them — whether that's financial data, health information, personal content, or their professional reputation.
Why founders get this wrong
Established companies have earned trust through years of consistent behavior. Startups start at zero. Founders assume that a good product earns trust automatically. In reality, trust is built through signals: social proof, security certifications, familiar design patterns, transparent policies, and word-of-mouth. A startup without trust signals is asking users to take a leap of faith.
Signs you're making this assumption
- Your product handles sensitive data but you haven't invested in visible security measures
- You don't have testimonials, case studies, or recognizable logos on your site
- Users start signing up but abandon when they reach the data-sharing or payment step
- Your product requires login or personal info before showing any value
- You're in fintech, healthtech, or any regulated industry without visible compliance badges
How to actually test trust
Ask about trust transfer: 'What would a new [type of tool] need to show you before you'd trust it with your [data/money]?'
Test trust signals: A/B test your landing page with and without testimonials, security badges, and press logos. Measure conversion difference.
Ask about past trust decisions: 'When was the last time you trusted a new app with your [financial data/health info]? What made you trust it?'
Offer a trust bridge: let users try with fake data, a sandbox mode, or limited access before requiring real information.
Run a Validue campaign asking target users what trust signals they need to see before adopting a new product in your category.
The one question that exposes this assumption
“If a brand-new company you'd never heard of offered this product, what would you need to see or know before you'd give them your [data/money/information]?”
