The challenge
For Taxfix, creative testing is a central part of the growth engine and iterating on wins, reacting to trends, and producing fresh ideas at scale is critical. Taxfix needed a solution that would make creative iteration and the production of fresh ideas a core, repeatable capability - cutting the creative cycle from days to minutes.
How they used Superscale
The Taxfix team uses Superscale across all markets and products in the UK, Spain, and Germany. It serves as a shared creative system that enables all teams to operate independently but with shared capabilities and insights.
The key unlock was consolidating the entire creative workflow inside Superscale: from insights generation to the end-to-end production of new assets. Within weeks, the team produced hundreds of ads independently and inside the Superscale Agent.
The Agent supports the team as an additional creative strategist, copy writer, video producer, editor and designer: surfacing insights from platforms like Reddit, Meta, and TikTok, and translating them into testable ad concepts, refined scripts, storyboards, and finished assets.
Inside Superscale: How the Taxfix Team Uses Templates and the Agent
The Taxfix and Steuerbot team uses Superscale to create any type of video and static asset: using proven formats such as speaking characters and talking heads from Superscale's template library, and generating completely new ideas such as gamified product walk-throughs, animated statics, and Sora-inspired visuals.
Being able to generate multiple iterations of a winning static in minutes - or test bold new ideas without planning complex, expensive productions - unlocks new creative opportunities at scale. Using the Agent to generate insights, ideate, write scripts, and produce ads empowers everyone on the team to find new ideas and bring them to life instantly.
