Built for how brands grow today

Data-driven strategy, the latest advertising technology and AI-powered tools, combined with years of hands-on industry experience.

What we do

Katalyst is a performance marketing agency built for how brands grow today, combining data-driven strategy, the latest advertising technologies and AI-powered tools with years of hands-on industry experience.

We act as the catalyst behind your brand's next phase of growth, using paid media advertising and performance marketing, two channels that have become essential for any business looking to scale online.

What sets us apart is how we work. The digital advertising landscape changes constantly: new platform features, evolving algorithms, shifting consumer behaviour. We stay ahead of it. We continuously bring AI-driven tools into our process, from audience targeting and creative optimisation to performance analysis and reporting. They support our team's thinking rather than replace it, so every campaign is sharper, faster and more effective than the one before it.

Behind every strategy is a team with years of specialised experience across industries, platforms and business sizes. We don't believe in one-size-fits-all advertising. We build strategies rooted in real data, tested approaches and a clear understanding of what actually drives revenue.

The result: brands that don't just run ads, but grow smarter, faster and more sustainably.

Karan Shah, Founder of Katalyst

Meet the founder

Karan has spent over 8 years in performance marketing, helping brands turn ad spend into measurable, scalable growth.

Over his career he has worked with 100+ clients across the globe, spanning food and beverage, fitness, e-commerce, hospitality, education, music artists, podcasts and more. That range gives him an unusually versatile understanding of what drives results across different business models and customer journeys.

His expertise was forged at two fast-paced digital start-ups, where he worked at the meeting point of strategy and execution, staying ahead of platform updates, algorithm shifts and new ad features before they became industry standard. That experience shaped his approach: data-driven, adaptable and always focused on what moves a business's bottom line.

Today he channels it into Katalyst, building a team and process designed to give every client the same attention, insight and results-driven thinking that has defined his career.

Who we are

We're a team of performance marketers driven by one belief: brands deserve advertising that delivers real, measurable results.

We combine strategic thinking with platform expertise to help businesses grow their digital presence and revenue, not through guesswork, but through data-backed paid media and performance marketing.

We're always looking for sharp, inventive people who know how to grow a brand's digital footprint. If that sounds like you, we'd love to have you on the team.
