About Dexxter
NPS-targeted outreach to 257 customers. 65% email open rate. Multi-hook editing for performance marketing across TikTok, Meta, and Google.
The Challenge
Dexxter is a Belgian accounting SaaS with 11,000+ active customers. They had plenty of happy users but no scalable way to turn satisfaction into video content. They'd previously used VideoAsk but found it limited. Their marketing team runs heavy performance marketing on TikTok, Meta, and Google - campaigns that demand authentic, UGC-style content with multiple ad angles for A/B testing.
The Solution
HappyClient deployed a video testimonial system optimized for performance marketing. NPS-based targeting contacted only 257 customers who had left positive reviews. Six carefully crafted questions extracted multiple ad angles from each recording. Multi-hook editing turned single videos into 2-3 different 20-60 second clips for A/B testing across campaigns.
How HappyClient helped:
- Remote-first video collection with no production crew needed
- Guided interview questions designed for authentic responses
- Personalized outreach that drives high response rates
"The content quality is really good... the clip selection, I find that really well done. The message of those videos is good."
The Results
What Dexxter achieved with HappyClient
257 NPS-targeted customers contacted with 65% email open rate
11 authentic video testimonials collected in one campaign
15 edited videos with multi-hook extraction for ad variants
Performance marketing ready: vertical format with Dutch subtitles

Faqs
Everything you need to know about HappyClient. Can’t find the answer you’re looking for?
Will customers actually participate?
Yes - and the numbers prove it. Recording takes just 3 minutes with guided questions, no app install, and works on any device. The Lean Six Sigma Company hit a 73% response rate, the Belgium Startup Awards achieved 89% engagement, and Moonbird collected 27 testimonials on a sensitive health topic. The personal, low-friction approach makes people want to participate.
Does my customer need to install anything?
No. HappyClient runs straight in the browser, on any device. Your customer clicks the link, gives recording consent, follows the guided questions, and submits the video - no app to download, no account to create, no extra friction.
How quickly can we go live?
Creating your first branded video interview takes 1 to 3 minutes. Share the link and the moment your customer finishes recording, the raw video lands in your library in less than 20 seconds. Need fully on-brand, professionally edited videos? They're ready within 2-3 hours. ENGIE went from first call to live deployment in just 4 days.
How fast can we use testimonials in our campaigns?
Hours, not weeks. Every submission gets basic editing applied automatically in seconds; professionally edited, on-brand cuts ship within 2-3 hours. So once a customer finishes recording, you can drop their testimonial into an email, ad, landing page, or sales deck the same day.
Are the videos on brand?
Every video is automatically styled with your brand colors, logo, fonts, and custom templates. The recording experience itself is fully branded too, so your customers feel right at home. ContourLab's fashion brand clients said the results looked better than what they'd get from a production agency.
How about other languages?
Your customers can record from anywhere in the world, on any device, in any language. JustBite collects testimonials across 8 European countries without a single trip, and Shinnoki gathers architect testimonials in 3 languages from Belgium to Japan - all run from HQ.
