Enlisting the right support for a business can be the difference between mediocre results and explosive growth. If you’re not sure how to start, don’t panic — we’ll outline eight growth marketing agencies we’d trust our lives with (almost)!

Growth versus traditional marketing agencies

Let’s get the elephant out of the room. What’s the difference between a traditional marketing agency and a growth marketing agency (or growth hacking agency), anyway? Isn’t it just another buzzword that sounds cool?

A growth marketing agency does sound cooler, but there are some clear distinctions.

Traditional marketing agencies help you build a brand and spread the word. Gradually. To speed up the process, growth marketing agencies take a data-driven approach, running various experiments to see what brings the best results.

This involves a focus on “pirate metrics” or AARRR:

  • Acquisition
  • Activation
  • Retention
  • Referral
  • Revenue

Because what’s better than generating leads? Ensuring those leads result in consistent revenue.

You might also hear growth agencies call themselves “full-stack” since they fuse multiple aspects of marketing together. No shade to regular marketing agencies.

How to choose a growth marketing agency

Now we’ve convinced you that growth marketing is the future, you might be tempted to hire a growth hacking consultant or marketer in-house. Maybe the thought of welcoming a permanent face to your team gives you a warm, fuzzy feeling.

We can’t tell you what to do. What we can do is give you a breakdown of the pros and cons of using an agency so you can make an informed decision.

Pros of agencies

  • Focus on growth marketing day in day out
  • Multiple specialists across different disciplines
  • Greater flexibility — change your approach, who you work with, etc.

Cons of agencies

  • Spread across various clients — less attention for you
  • Knowledge hoarding (may withhold critical intelligence)
  • Little or no understanding of company culture

Everyone has different priorities — but if growth comes first for you, an agency is probably the right choice.

Of course, they’re not all made equal.

Always vet an agency before agreeing to work with them. That means:

  • Asking for case studies
  • Taking advantage of any free consultations
  • Starting with a small engagement (e.g. growth audit) to determine fit

Or, let us vet them for you. Below are nine stellar agencies we can vouch for.

Ladder.io

  • Founded in: 2014
  • Website: https://ladder.io/
  • Specialisms: PPC, CRO, SEM, SEO, Growth Hacking
  • Pricing: Starting from around $5,000 per month
  • Ladder team on GrowthMentor: Co-founder @ Ladder, Michael Taylor; Director of Growth @ Ladder, Tomek Duda; VP Client Growth @ Ladder, Adam Wesolowski

Remember how we said growth marketing agencies are data-driven?

We weren’t kidding.

To inform their marketing decisions, Ladder uses machine learning technology developed over thousands of hours of helping firms like yours.

How many “regular” marketers can say the same?

They also take a lean approach, using a minimum viable test to drive as much growth as possible with minimal investment.

Past clients include a host of Fortune 500 companies and Y Combinator startups, including Facebook and Booking.com.

Money Dashboard co-founder Will Egerton-King credits Ladder with helping his company use their best features to drive revenue, resulting in a great ROI.

To learn more about how they achieve results, read their advice for achieving ROI targets. Or, if you really want some inspiration, check out the 800+ growth tactics that form their “playbook.”

Booking is the 3rd largest eCommerce company in the world. Yet we do still see that there’s value in hiring a growth agency – and not just because growth is a buzzword that we like. It took us some time to calibrate on that with Ladder, but after that, we quickly understood what Ladder can and can’t do, and we doubled down on what we can do together. It was Ladder’s iterative way of thinking – of building experiments and testing things – that really helped the dynamics of doing marketing for a big company like ours.

Swidia

  • Founded in: 2018
  • Website: https://swidia.com/
  • Specialisms: Paid Social, Paid Search, Performance Creative Testing, User/Customer Acquisition, Retention, Growth Hacking Strategy
  • Pricing: Starting from around $5,000 per month
  • Swidia team on GrowthMentor: Co-Founder, Chief Executive Officer – Jack Chen; Co-Founder, Chief Growth Officer – Frank Jiang; Head of Performance Marketing – Tatiana Dmytruk

Let’s keep things simple.

If you’re a founder/marketing/growth leader at a Series A-C consumer startup, you’re likely going to need to build a strong brand growth marketing foundation and implement strategies to scale users.

That’s when people hire Swidia.

SWIDIA is a specialized growth marketing team with a hyper-focus on scaling users for consumer startups. They’ve played instrumental roles during the growth stages of Cameo, Radish Fiction, STEEZY, and many more.

There are 3 ways they can help you get over the growth hurdle:

  • User Acquisition Team – efficiently acquire new users and customers through performance marketing adapted to a post-IDFA environment.
  • Creative Studio – drive action with champion creatives that meet both growth and brand needs, and get actionable creative insights to iterate and improve future assets/creatives
  • Growth Studio (corporate innovation) – Launch new ventures and design businesses with the latest growth approach tried-and-true on the frontline of venture-funded startups.

You’ll work with a group of experienced operators and specialists that become a true extension of your growth marketing team. Let’s get it.

SWIDIA was instrumental in scaling our users during Series A and B stages. It’s rare to find an agency that is both creative and analytical but SWIDIA certainly is both. We worked together to build a scalable acquisition engine that was rooted in testing and iterating.. We saw significant improvements in LTV:CAC, while scaling ad spend cost-efficiently in a big way. I highly recommend working with them if you’re looking for a growth team.

  • Website: https://www.orangepegs.com/
  • Specialisms: Growth Hacking, Inbound Marketing, Sales Alignment/Enablement
  • Pricing: Starting from $2,000 per month
  • OrangePegs Team on GrowthMentor: VP of Growth and Partner @ OrangePegs, Jason Barbato.

With a name inspired by Orange County, this agency describes themselves as “iterative” and “experimental.”

They use their talents to boost the growth of brands, startups, staffing agencies, professional services firms, software companies, or any other B2B or B2C organization.

Unlike most of the other agencies on this list, Orange Pegs focuses on a hybrid model of growth hacking and inbound marketing — and they’ve got the Hubspot gold partner certification to prove it.

If you’d like to put their methods to the test (which you totally should), have a go at the Growth Plan Builder on their website front page. It will help you get into the growth marketing mindset and build up an idea of what you can expect from working with an agency.

Alternatively, check out their blogs about execution before you launch a growth hacking project or forgotten aspects of lead generation.

Current client Mark Arrow can’t recommend Orange Pegs enough because they are strategic, systematic, agile, and adapt their model not just to improving discovery and user experience, but also bottom line business outcomes.

We had a new product, and no marketing function when Orange Pegs became our partner. With their help we now have a complete, agile, scalable inbound program that has supported two more product launches, event campaigns, and more. Through the fundamentals and also a data-driven, experimental approach we are always learning and pivoting, and it has led to tremendous gains in qualified leads, social media engagement, and organic website traffic. OP is a strong ally that has helped the rapid growth of our business; we feel lucky to have them!

  • Website: https://kurve.co.uk/
  • Specialisms: SEO, Conversion Rate Optimization, PPC, Content Marketing, Growth Hacking
  • Pricing: Starting from $2,000 per month
  • OrangePegs Team on GrowthMentor: Founder @ Kurve, Oren Greenberg.

Kurve isn’t just an agency — they’re also a consultancy. What gives them the right to such a mighty claim? Whatever you want help with, they can assign you a team of specialists tailored to your needs.

They work with both startups and corporates to help them grow using the scientific, data-led approach you’d expect from an top-notch agency.

Kurve has an almost overwhelming number of testimonials on their website — no, really, go look for yourself.

One of the standouts comes from the co-founder of NextFree, who said they bring a “scientific rigor” and “test and learn approach” that is a great complement to agile companies.

Still not convinced? You will be when you read their entertaining guides on setting up the perfect chatbot or whether organic social media reach is a thing of the past.

Oren and the team at Kurve were vital in providing a digital strategy that got us excellent results within our budget and within impressive timeframes. His experience and insight were matched by his enthusiasm and dedication to helping us grow, as he consistently went above and beyond to provide valuable support. It has always been a pleasure to work with Oren, as his responsiveness and creative approach mean that he genuinely strives for excellence. I’d recommend Oren for all matters related to digital marketing when looking for a provider with integrity and honesty.
