I built a testimonial tool — here's what I learned

I was stuck. My SaaS was converting okay, but nothing was moving fast, and I couldn't figure out why.

I had a good product. Customers were using it. Some loved it. But the moment I'd ask them for a testimonial, it was radio silence.

The problem wasn't hard to see: I was asking wrong.

I'd shoot an email with a form link. Maybe 1 in 20 people clicked it. Of those, half came back with something like "Great product!" that told exactly nobody anything. And then I'd do nothing with it. It sat in a folder.

So I decided to fix it.

What I tried first

I tested everything:

• Manual collection. I called customers directly and asked them face-to-face. Response rate was 70%, but I can't call 1,000 people. Not scalable.
• Google Forms. Free, but the UX made it feel like a telemarketing survey. Response rate: 4%.
• Competitor tools (Senja, Testimonial.to). Both work well, but they were overkill for what I needed. I was paying $80–100/month for features I wasn't using. Plus, their video collection is behind a paywall upgrade.
• Spreadsheet + Zapier. It worked, but it was janky. No follow-up automation. No dashboard. Just me manually chasing people down.

None of these felt right. The paid tools were too expensive for early-stage. The free ones were too hard to use. Manual work didn't scale. Spreadsheets broke when I had more than 50 testimonials.

What I ended up building

I built something simple: a form that doesn't feel like spam.

• One question at a time. Not five form fields. Not a survey. Just "What was the biggest pain before, and what changed for you?" That's it.
• Video option. Most people pick text. Some send a 30-second video message. Video testimonials convert 2x higher than text, so I made it stupid easy to do.
• Embeddable widget. It displays on my landing page as a rotating Wall of Love. Looks modern but doesn't take two hours to set up.
• Automatic follow-up. If someone doesn't respond in 7 days, they get a gentle reminder. Response rate doubled because of this.

The whole thing took three weeks to build. I automated the parts that were painful in the manual process. Didn't try to solve 15 different use cases. Solved exactly the one I had: getting testimonials from people who just got value, and displaying them where they actually moved conversions.

The numbers

• Response rate: 48% on the first ask (up from 6% on email forms). The timing window matters more than anything — ask within 48 hours of the win.
• Video rate: 18% of respondents chose video. Video testimonials convert 2.3x higher than text when displayed in onboarding emails.
• Time to first testimonial: 3 days (down from 30 when manual).
• Trial-to-paid lift: Conversion went from 12% to 17% over two months after adding testimonials to the landing page. That's a 42% lift just from social proof.
• Retention: Testimonials in onboarding reduced churn from 8% to 5% per month.

The most surprising finding: volume wasn't the play. I had 30 testimonials sitting on a page. Once I isolated the 5–6 best ones (specific outcomes, problems solved, numbers) and rotated them through email sequences, the real lift showed up. Quality + placement over volume, every time.

What I'd do differently

1. Ask within 48 hours of the win. I waited weeks and got half the response rate. The moment a customer hits an aha moment, ask then. They remember the before-pain clearly.
2. Incentivize specificity, not volume. I started asking for testimonials broadly. Now I have a script: "Tell me one specific thing that changed for you — time saved, cost reduction, confidence." One number matters more than ten generic quotes.
3. Own the follow-up. Automated reminders feel pushy, but they work. People want to help if it's easy. They just need a nudge.
4. Don't collect until you're ready to deploy. I had 50 testimonials before I used any. Build the embed widget first, then collect the testimonials to fill it. Reversed order wastes both time and momentum.
5. Track which testimonials actually convert. Testimonials from founders converted 3x higher than general customer testimonials for my product. I was showing the wrong ones prominently. Data changed what I prioritized.

Building a tool around this

A few people saw what I was doing and asked if I'd sell it. The problem was universal — every founder has the same friction: low response rates, no follow-up automation, testimonials that don't drive conversions because they're scattered and generic.

So I built Glowboard: a testimonial collection tool designed for founders like me. Simple form, video option, Wall of Love widget, automatic follow-up. No $80/month price tag. €39/month, and it solves the exact problem I had.

Founders who were getting 8–12% response rates on manual collection are now hitting 40–50% with the form. Testimonials buried in spreadsheets are now on landing pages moving trial conversion 15–30%. And they're spending 2 hours per month on testimonials instead of 10.

The win wasn't the product. The win was solving the specific friction I felt. Most tools try to be everything. I just solved: "How do I get testimonials without it being painful, and how do I make sure they actually move the needle on conversions?"

The 20% of testimonials that drive 80% of the conversion lift are usually specific, outcome-driven, and identity-matched. The rest are decorative. Once you know which ones those are and put them in the right place, the lift is real.
