About this gig

Want ads that make people stop scrolling, tap, and install? I create high-converting video ads and playable ads for mobile apps and games.


What I offer:

- Video Ad 1 concept with 5 small iterations (different hooks, text, and CTAs) so you can quickly see what works

- Pro Video Pack: 3 different concepts, each with 5 iterations (15 videos in total), built for A/B testing

- Playable Ad: an interactive HTML5 playable with an end card and clear CTA, ready for major ad networks


Why work with me:

- Hook-first approach, designed around the first 3 seconds

- Built for mobile: vertical and horizontal formats, fast and lightweight files

- Clear communication and quick revisions

- Files delivered in the formats your ad platform needs


How it works:

1. Send me your app or game link and any gameplay footage

2. We agree on the concept and style

3. I deliver the first version for your feedback

4. Final files and handover


Not sure which package fits? Message me before ordering, and I'll recommend the best option for your goals and budget.
