See how we led the rebrand for RevelX, creating a new modern brand embodying their focus on growth and strategic innovation.
Design, data, content, campaigns: all the roles you can't justify hiring individually.
Your time goes back to strategic decisions only you can make.
Every project, deadline, and result tracked and under control.
| Hiring in-house | Your growth team | |
|---|---|---|
| Cost | One senior marketer's salary, and you still need 5–9 different skills | A blended €100/hr across 5–9 skills, including specialists who bill €110–150/hr elsewhere |
| Time to start | Months to hire, train, and get up to speed | Ready to start working from week one |
| Flexibility | Fixed headcount, hard to scale down if plans change | Adjust capacity as your goals change: no lock-in, no exit fees |
| Risk | You pay salary and benefits whether it works out or not | Cancel anytime |
| Invoicing | Payroll, plus separate freelancers for what you can't cover in-house | One monthly invoice |
A single in-house marketer can't be your strategist, copywriter, paid media specialist, and HubSpot expert at once. So you either hire five people, or hire freelancers and manage them yourself.
A Growth Team gives you that whole skill set from day one. One fixed fee, and the right specialists work on whatever the plan needs that month.
At SUM Digital, we don’t believe in one-off campaigns that disappear after a month. We believe in the Growth Loop: our methodology tested over 10 years and 150+ B2B projects. It’s how we make sure your commercial efforts work together to consistently capture the right leads and protect your ROI.
1. Growth Strategy
Data & Insights
We look at what your numbers already tell you: where people drop off, what converts, what doesn't. This becomes the foundation for every decision that follows.
Growth Marketing Plan
We turn your goals into a concrete plan: which channel to use, what to say, and in what order. It gives every later step a clear reason to exist.
Messaging
We build your message around your customer's problem, not your service or product. When people see themselves in the story, they understand what you do and why it matters to them.
2. Implementation
Campaign creation
We set up structured campaigns with clear goals and audiences. This is where separate pieces come together into one coordinated push.
Content creation
We write and design the content your campaigns need: pages, emails, ads, social media posts. Each piece is created to move people one step closer to buying.
Customer Journey Implementation
We build out each step a customer takes, from first step to purchase, so nothing gets left to chance. Every touchpoint is there for a reason.
3. Demand & Revenue Generation
Lead Nurturing
Not every lead is ready to buy right away. We keep them engaged with the right message at the right time, until they are.
SEO & AIO
We help your brand show up when people search: on Google and in AI tools like ChatGPT, Gemini, or Perplexity. Being found is the first step to being chosen.
Social Media Campaigns
We run campaigns on the platforms your customers use, designed to get attention and drive them towards your site of offer.
SEA
We run paid search ads so you show up right when someone is actively looking for what you offer, not just hoping they find you.
4. Scaling
Consumer Psychology
We apply proven consumer psychology frameworks to your messaging, so it aligns with how people actually make decisions.
Conversion Optimization
We A/B test and refine pages and forms to turn more visitors into customers, using real data and behaviour insights.
Customer Journey Optimization
We don't stop once your customer journey is in place. We look at where people get stuck or drop off, and fix those points to optimize your funnel.
