Most SaaS sites are still trying to sell with clever headlines and polished UI mockups. Meanwhile, the assets that actually convince buyers—real screens, real workflows, real results—are buried in Loom links and Slack messages.
Customer proof design is about dragging those messy, real moments into the center of your homepage, pricing, and onboarding so a stranger can see your product working in the wild, not just in Figma.
Pretty UI Is Not Proof
A clean interface makes people feel safe, but it doesn’t make them believe.
Buyers want answers to three questions, fast:
- Does this work for people like me?
- What does it actually help them do?
- What changed after they used it?
If all they see is “Beautiful dashboards for modern teams,” you’ve given them nothing to trust. A 30–60s clip of someone completing a real task and saying “we went from X → Y in Z weeks” does more than any “AI‑powered, end‑to‑end” headline ever will.
Your Best Case Studies Are Hiding in Support Threads
Most teams say they “don’t have case studies yet.”
In reality, they have:
- Looms customers recorded for onboarding or questions
- Slack/Discord messages like “this saved my ass today”
- Emails where someone explains what changed after going live
Those are already case studies—just unstructured.
Look for moments like:
- “We cut onboarding from 14 days to 3.”
- “Trial‑to‑paid went from 12% to 21%.”
- “Reporting went from Monday‑killer to 10 minutes.”
You don’t need a 6‑page PDF. You need one clear before/after, one workflow, and permission to show it.
If It’s Not Next to the CTA, It’s Not Doing Any Work
The worst place for your best proof is a lonely “Testimonials” page in the nav.
Put your strongest evidence where hesitation lives:
Homepage hero
- Small “See it in action (30s)” clip beside your main CTA
- One line underneath: “We went from X → Y in Z weeks using this”
Pricing page
- For each serious plan, one focused quote:
- “Pro → Took us from 12% → 21% trial‑to‑paid in 6 weeks.”
- Optional mini-clip: “How this plan is used by a 5‑person team”
Onboarding success states
- After “Connected your data,” show:
- “Teams like yours use this step to send weekly investor summaries in 3 minutes.”
If proof isn’t near a decision, it’s just decoration.
“Great Tool!” Is Useless
Most testimonials read like forced LinkedIn endorsements:
- “Great product, amazing support!”
- “Love the UI, highly recommend.”
Nice for your ego, useless for your conversion rate.
Use this pattern instead:
“We went from A to B in timeframe by using feature/flow.”
Examples:
- “We cut onboarding from 14 days to 3 by using their guided checklist instead of email threads.”
- “We went from 4 tools to 1 dashboard and finally stopped copying numbers between sheets.”
- “We moved from 1 landing page a quarter to 1 a week once we moved to their system.”
Specifics create a mental movie. Vague praise feels like you wrote it yourself.
Screens and Clips Beat Wall-of-Text “Stories”
Nobody wakes up excited to read a 1,500‑word case study. They will watch a 30–60 second moment that looks like their own day.
Design a few simple building blocks you can reuse:
- Result card:
- “14 days → 3 days client onboarding”
- Name, role, company (or at least segment)
- Screen + caption:
- Real product screen (with sensitive bits blurred)
- One line: “This is the view our ops team uses every Monday to close the books in 15 minutes.”
- Quick clip:
- 30–60 seconds of someone sharing their screen and narrating what changed
- Embedded next to a CTA
These blocks are easier to maintain than long case studies and can live all over your product surface.
Authentic Beats “Production Quality” Every Time
Founders overestimate production value and underestimate honesty.
You don’t need:
- A film crew
- A script
- A perfect background
You do need:
- Decent audio
- A clear outcome (“we went from X → Y”)
- Someone who actually uses the product, talking like a human
A slightly rough Loom from a real customer will convert better than a glossy brand video that sounds like an ad.
The Question That Should Haunt Your Next Redesign
Before you touch colors, layout, or fonts, sit with this:
“Where on this page can a stranger see my product working in the real world, for someone like them?”
If the answer is “nowhere,” you don’t have a design problem yet.
You have a proof problem.
Fix that first. The pixels can come later.
