About The Lean Six Sigma
From zero marketing-ready videos to a content pipeline that feeds social media for 5+ months.

The Challenge
The Lean Six Sigma Company had thousands of certified professionals but zero marketing-ready video content. Their training alumni were spread across industries and countries, making traditional video collection impractical.
The Solution
HappyClient helped The Lean Six Sigma Company design a targeted outreach campaign to their most engaged alumni. Personalized recording invitations with guided questions about their certification journey resulted in an exceptional 73% response rate.
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
"A 73% response rate was beyond anything we expected. The personal touch made alumni want to participate."

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.
