Hello from East London!


Hi! I’m Karola, a growth & marketing expert with 12 years of experience.

I help B2C and B2B tech companies with growth strategy, branding, marketing audits, and paid ads.

I’ve spent 12 years in growth roles, four of them as Global Head of Marketing at Bolt, where I scaled the team from 2 to 30+ people across 30+ markets. As a freelance marketing consultant, I’ve run marketing audits and growth strategies for 50+ tech companies across Europe, the UK, and the US, and managed €500-€20,000,000 Meta campaigns for 30+ consumer and B2B brands.

I write this blog and the bi-weekly Marketing Fix newsletter.



What I do best:

↳ Zero-to-one growth strategy: Figuring out how to get a product off the ground and find the first 10,000+ users.
↳ Paid Ads at scale: I’ve managed €10M+ budgets across social and search, focusing on real revenue, not vanity metrics.
↳ Growth Systems: I’ve built the Marketing Fix newsletter (15k+ subscribers) and blog (50k+ monthly readers) from my own experiments.


Need help with creating, launching, or fixing your marketing strategy?

I normally work with early-stage B2C and B2B tech companies. The usual project scope is 2-6 months.

I’m based in London and open to freelance work across Europ, the UK, and the US.
