Sound familiar?
We get visitors, but hardly any enquiries or meetings.
Our campaigns deliver leads that sales can't do anything with.
I don't know which marketing euro actually drives revenue.
How we help
We build a lead engine that attracts the right people, warms them up and hands them to sales as qualified leads. Fully measurable, so you always know what works and where your money goes.
Why Customer Impact
We start with your ideal customer and your goals, not with a channel. That way every euro reaches the right people instead of disappearing into noise.
No scattered campaigns, but one system that attracts leads, warms them up and hands them to sales fully qualified.
SEO, Google Ads, LinkedIn and content: we pick the mix that actually reaches your audience, not our favorite tool.
We measure qualified meetings and revenue, not clicks or impressions that only look good in a report.
About Customer Impact
Customer Impact is a digital marketing agency founded by Tanguy De Keyzer. For more than 10 years we have been building the growth engine of startups, scale-ups and established companies.
Lead generation is the thread running through everything we do. We connect it to your sales team and your other channels, so enquiries stop being a coincidence and become a system that keeps performing.
What we stand for:
What we do
We work out together who your best customers really are, so every euro goes to the right people instead of into noise.
Lead generation through the channels that actually reach your audience: SEO, Google Ads, LinkedIn and content.
Pages that turn visitors into enquiries, with clear CTAs and minimal friction.
Automated follow-up that warms cold leads until they're ready for a conversation.
Target your dream accounts with marketing and sales fully aligned, for bigger deals.
We steer on the numbers that count: cost per lead, MQL to SQL and, ultimately, revenue.
Our process
We define who your best customers are and what a qualified lead really means for you.
We choose the channels and build the funnel that guides your audience from first touch to enquiry.
We launch campaigns, landing pages and content that attract and convince the right people.
Leads are warmed up and qualified, so sales only spends time on people who are ready.
We measure pipeline and revenue, cut what doesn't work and scale what does.
Many companies run campaigns without a system underneath. Clicks come in, but meetings don’t. Sound familiar? The cause is rarely a single channel: what’s missing is a well-designed funnel that attracts the right people, warms them up and hands them to sales at the right moment.
The result is predictable: marketing delivers leads that sales can’t use, sales complains about quality, and nobody knows which euro actually drives revenue.
We build lead generation as a system. First we define who your ideal customer is and which channels actually reach that person. Then we set up campaigns, landing pages and follow-up that lock together seamlessly, and we measure every step of the funnel.
You see exactly where leads come from, what a lead costs, and how many become customers. Marketing and sales finally work from the same numbers, towards the same goal: more revenue. And yes, that makes work a lot more pleasant too.
A lead that sales can't use isn't a result, it's wasted budget. That's why we measure quality rather than volume: how many leads become meetings, and how many meetings ultimately become customers.

Case studies
Facilicom IFM wanted to enter a new region without losing lead quality. With more than 70 LinkedIn campaigns as a benchmark, we built a value proposition per ABM segment, tested against a threshold for conversion costs and scaled the winners. In 6 months MQLs rose by 189%, with 22% lower monthly advertising spend.
Read the caseSuivo wanted more results from less media budget. We adjusted the paid campaigns, content and funnel on quality instead of volume. In 2025 qualified web leads rose by 33% at a 61% lower cost per lead, and the lead-to-opportunity ratio went from 19% to 28%.
Tryve, a B2B work management company, wanted more and better leads. We combined lead generation with conversion optimization, paid and social campaigns, email and correct tracking in Google Analytics. The result: twice as many leads, with better lead quality.
In all honesty
We hadden een andere agency die meteen met ons in zee wou gaan. Hier worden we met de neus op de feiten gedrukt, en dat is voor ons meer waard dan: tuurlijk, geef mij je geld en we proberen maar iets.You have surprised me in multiple ways the last few weeks.Contact us
Briefly tell us what it is about. You get a personal reply from Tanguy or someone from the team, not a call centre.
Pricing depends on your goal, market and channels, media budget separate. That includes management of 1 to 2 ad channels, landing pages, lead follow-up and CRM feedback. After a short intake you get an approach with a tailored proposal. Fill in the intake and you'll hear within 24 hours what's realistic.
Paid channels (Google Ads, LinkedIn) deliver the first leads within weeks. Organic engines like SEO and content build up over a few months, but keep performing afterwards. We combine both, so you grow fast and sustainably.
We choose based on your audience, not on hype: usually a mix of SEO, Google Ads, LinkedIn, content and marketing automation. We define the right mix together after the intake.
A lead that matches your ideal customer profile and shows real buying intent. We don't just measure volume, but quality: how many leads become meetings, and how many meetings become customers.
