If we wouldn’t have Billo, we wouldn’t have the results we’ve had. The quality of the actors is strong, they execute scripted briefs on a high level, and the platform is very streamlined, so that has a big impact. As of now, around 75% of all our videos are from Billo, and most of our successful videos are from Billo too.
Eitan Malki
Creative & Studio Lead, Mozo
Mozo is a B2C cybersecurity company serving a U.S. audience with identity protection and a scam prevention app, available in the App Store and Google Play. User acquisition drove the business, and video ads were the start of the customer journey.
Eitan Malki led creative and studio at Mozo and built the company’s UGC engine from the beginning. Mozo used Billo early in the product launch to source creators, run structured hook tests, and keep production moving fast.
Challenge
Build a high-volume UGC pipeline for a precise, regulated product
Mozo’s ads had to be clear, compliant, and specific. That meant creators needed to follow tight scripts, deliver with charisma, and help the team test lots of variations without bogging down in casting, contracts, and back-and-forth.
Implementation
Scale scripted UGC with repeatable testing
Mozo used Billo to move quickly from casting to production to iteration. The team leaned on Billo’s Top Ad Performers to avoid wasted time, prioritized creators who matched their 35–55 audience, and ran a disciplined testing system built around hooks and multiple creators per script. Eitan leaned into volume: they needed a lot of quantity to find winners, fast.
Targeted creator selection
Mozo’s target audience skewed older, so Eitan typically selected creators 30+. Instead of browsing endlessly, he started with Billo’s Top Ad Performers, then filtered by one main factor: charisma that made people stop scrolling.
Scripted briefs, executed cleanly
Because the product demanded precision, Mozo’s briefs were highly scripted. Creators still delivered well: they read the script, followed it closely, and executed at a high level, without the team needing to train every creator from scratch.
Hook variation testing at volume
Mozo’s core method was structured and repeatable: one script, four hook variations, and at least five creators. This approach helped narrow down what worked, reduce wasted effort, and keep performance from relying on luck.
Formats that matched how people watch
Mozo found that simple, low-production UGC performed best. TikTok-style hooks outperformed brand-first intros, especially early on when audiences didn’t know Mozo yet. The team also leaned into a more square format, rather than fully vertical, as a consistent winner.
Positive outcomes
Higher CTR, longer watch time, and a smoother workflow
Performance lift. CTR improved from 2.98% to 3.63%, average play time rose from 00:06 to 00:11, and CPA decreased by 15%.
Billo drove the winners. About 75% of Mozo’s videos came from Billo, including most of their top performers.
Less overhead, more output. Billo removed the time-consuming work of finding actors, handling contracts, and chasing people down, so the team could focus on creative performance instead of logistics.
Reliable creator quality. Eitan reported that about 95% of Billo creators he worked with were really good, with very few issues across high volume.
Future plans and recommendations
More platform coverage, expanded testing
Mozo planned to keep scaling Billo as a primary content source while expanding on Meta and TikTok, as well as other channels. The team would continue running high-volume hook tests, relying on Top Ad Performers to move fast without sacrificing quality.
