Creative Hypothesis Builder

Turn a design interview and competitor research into a testable creative hypothesis. Use this during or after a client discovery session.

Step 1 of 5

Business Context

Start with what you learned in the design interview. Who is this business and who are they trying to reach?

This section captures the inputs from your design interview (Stage 1). If you haven't done the interview yet, use these questions as a guide.
Be specific: demographics, mindset, circumstances, what brought them here.
Name the emotional response. This is more important than how it looks.
The real differentiators — not just what they say, but what's actually true.

Competitor Landscape

What did the competitor analysis reveal? This is Stage 2 — the patterns and gaps that inform the hypothesis.

List names or URLs — typically 3-5 direct competitors.
Common layouts, messaging, imagery, calls-to-action. What does "normal" look like in this space?
What are competitors NOT doing that this business could own?
Patterns, clichés, or approaches that would make this site blend in with everyone else.

Brand & Design Direction

How should this translate visually? Capture the design direction before writing the hypothesis.

Select all that apply. These aren't rules — they're starting signals.
Can be from any industry. What matters is the feeling, not the sector.

The Hypothesis

Now bring it together. A creative hypothesis is a testable statement that guides every design decision.

Format: "If we present [what] in [this way], users will [do this]."
You can create multiple hypotheses — one per key design challenge.
Hypothesis 1
If we present ___ in a way that is ___, users will ___.
What's the observable signal? This becomes the benchmark for design review.

Next Steps & Constraints

Once the hypothesis is approved, the next step is mood-boarding and concept development. We can help with that.
