ABOUT GROWLLO
Built by operators. Run for brands that mean business.
Growllo was founded in 2022 by a former in-house performance lead who had grown tired of briefing agencies that had never actually run the channels they were charging to manage. Every person at Growllo has operated TikTok Shop or Amazon FBA in-house before joining.
THE STORY
Why we exist.
In 2021, James Whitfield was Head of Performance at a £50M/yr DTC brand. He'd hired three different "TikTok agencies" in 12 months and fired all three. Not because the work was lazy — because none of them had ever actually run TikTok Shop ads for a product brand. They'd run awareness campaigns. Influencer campaigns. They had no idea how VSA attribution worked, how affiliate commission structures should be modelled, or how to read a TikTok Shop Seller Centre dashboard.
He built what he couldn't hire. Growllo launched in 2022 with one client and a simple rule: no one joins the team who hasn't operated these channels in-house at a brand doing real revenue. We've stayed at 12 people on purpose. We don't want to be a 50-person agency with junior account managers doing the actual work.
Every Growllo client gets a senior operator who has been in the exact situation they're in. That's the only reason our ROAS numbers look the way they do.
"The best TikTok Shop result we ever produced came from a £12k product in the pet accessories category. We got them to £340k GMV in 60 days. That only happened because we'd run pet category affiliate programs before and knew exactly which creator archetypes convert."

HOW WE WORK
What we stand for.
01
Platform depth over breadth
We say no to SEO, email, and Meta retainers. Depth on two channels beats shallow coverage on six.
02
Operators, not generalists
Every hire has run these exact platforms inside brands. No consultants who advise without accountability.
03
Numbers before narratives
ROAS, ACOS, GMV. Not "brand awareness" or "reach". Every decision is traceable to revenue.
04
Honest timelines
Week 3 is realistic for TikTok ROAS movement. Month 3 for compound effect. We don't sell miracles.

12 specialists, 0 generalists.
