What clients say

In their own words.

Three clients, three business models. Same system.

SOULX has been our paid media partner from day one. They took us from a bootstrapped launch in the Netherlands to scaling annual subscribers across multiple new markets in a single year. Every campaign was tracked, accountable, and drove real growth.
Stef Wijnberg Stef WijnbergFounder, Oogst App
SOULX played an important role in scaling our Ramadan 2026 campaigns. They helped us grow donations across both Google and Meta while maintaining strong efficiency. Their understanding of how the channels work together made a real difference in performance. The collaboration was transparent and focused on measurable outcomes.
Reuf Jašarević Reuf JašarevićDirector, Zakat Deutschland
SOULX led our paid social campaigns across Europe during the 2025 to 2026 heating season and delivered solid results. They helped us scale in our strongest markets while identifying clear opportunities for improvement in others. Their approach is structured, data-driven, and focused on long-term growth rather than short-term wins. They were a reliable and proactive partner throughout the season.

The engine

Three channels.
One system.

Acquisition, conversion and retention working as one. Your ads bring them in, search catches them, email keeps them coming back. One team, one fee.

Meta · TikTok · Pinterest Demand creation

Paid Social

We run the ads that bring new people in. Real creative testing, real audience research. Profitable conversions, not empty traffic.

Search · PMax · Shopping Demand capture

Google Search

When someone looks for what you sell, we make sure they find you. Budget put where it converts, not where it bleeds.

Klaviyo · Flows Retention

Email

Your most profitable channel once tracking is in place. Flows that turn one purchase into repeat revenue that compounds.

FAQ

Questions we actually get.

Short answers, no small print hidden. The full fine print lives on the pricing page.

What do your programs cost?

Validate starts at €750 per month for one channel (Meta), for ad budgets up to €2,000 per month. Always on is €1,200 per month for budgets up to €5,000. Scale the profit is €1,500 per month from €5,000 ad spend; above €10,000 monthly spend a 10% ad spend management fee applies. One-time setup is €750 for Validate and €1,500 for the other programs. Full breakdown on the pricing page.

How does the guarantee work?

At least 20% better results than your last agency, marketer, or specialist within your first 90 days with us, or we keep working for free until we get there, for up to 90 more days*. The baseline is fixed in writing during the Growth Audit: normally your previous 90 days, or the same period last year for seasonal businesses. Conditions apply, including a minimum ad spend of €5,000 per month; the full fine print is on the pricing page.

Which program fits my business?

Validate if you're getting traction but you don't know what works yet. Always on if your advertising has been ad hoc so far and you want a structure that always runs. Scale the profit if you know the model works and you want more revenue without destroying CAC. Not sure? That's literally what the first call is for.

What is the Growth Audit?

How every engagement starts. We read your business manager, ad account, tracking and funnel, and deliver a written report: where you stand, what a customer costs you today, and what we would do first. It is included in every program's setup, and it is where the baseline for the guarantee is fixed.

Which channels do you run?

Paid Social (Meta), Google and Email, plus the tracking and CRO to make them measurable. Acquisition, conversion and retention working as one system: ads bring them in, search catches them, email keeps them coming back.

Do you work with my type of business?

We look at your business model, not your industry: online sales and e-commerce, B2B lead generation, and app installs. We scale nothing before we can measure it properly. And if we're not a fit, we tell you who is.
