How did we make these decisions, and what does a good growth hacking agency look like? More on that below.

What to look for in a good growth hacking agency?

Here are our top recommendations of what to look for in a good growth hacking agency:

  1. Growth marketing is a process, so you want an agency that understands the process and the culture that is required to be successful. The emphasis should be on strategy over tactics.
  2. Be cautious of agencies that were previously more general digital marketing agencies, or that have specialisms in a particular area (such as paid advertising, or search), but that have rebranded as growth marketing specialists.
  3. Ensure the growth hacking agency works with companies like yours, both in terms of customer type (B2B or B2C), and industry. We’ve done the B2B screening for you and the “specialism/focus” column below provides some additional context.
  4. A good growth hacking agency will have typically used their experience to develop a bespoke process for new clients, avoid the “one size fits all” approach (because it definitely does not).

Which is our top pick?

If we had to pick one, who would we choose? (aside from ourselves, obviously).

Our top pick is Kurve (https://kurve.co.uk/).

Kurve – Growth Marketing Agency London

Their overall approach is exactly how we think a growth hacking agency in London should operate:

Kurve is a hybrid agency & consultancy. We support on execution or strategic insight. We work on a monthly retainer or on specific projects. Rather than squeezing your brief into a fixed team, we build the team tailored to your goals. We have a broad mix of digital marketing experts. Rather than generalists, we hand-pick specialists. We use a range of robust tools, some are partners and some we’ve built for specific marketing challenges.


In addition to a range of client testimonials throughout the site, they have an impressive list of success stories on their website. They detail their approach for both scale-ups and corporates, and also come highly recommended by our good friends at Growth Mentor.
