Your business has outgrown its data foundation
You have dashboards and plenty of data. But answering business questions still takes too much effort. You need a foundation that reflects how your business actually works, and stays reliable as it changes.
Different teams use different definitions for the same metrics.
Changes to source systems break reports and calculations.
Numbers are difficult to explain, validate or trace back.
Turn scattered data into a shared understanding
I connect your source systems and work with your stakeholders to define what the data means. From active customers to recurring revenue, your business gets clear, tested definitions that reporting and AI can both rely on.

From architecture to working answers
I make the architectural decisions and implement them. You get a working platform, useful reporting and the knowledge your team needs to keep developing it.
BI & data architecture
A foundation built to grow with you
Clear structure, automated checks and documentation make the platform easier to operate and extend.
Trusted business definitions
Numbers that reflect your business
Your teams can understand how each metric is calculated and agree on what it means.
Dashboards & reporting
One shared view of performance
I build operational and commercial reporting on shared business models, so teams work from consistent numbers and can trace results back to the underlying data.
Practical AI analytics
AI grounded in trusted data
I help you decide where AI adds value and where conventional BI works better.

What my clients say
I’ve helped B2B SaaS and technology companies connect their data, improve reporting and build foundations they can trust. Here’s how clients describe the results.

"I got sick and tired every morning of the CEO texting me on Slack, 'Hey, why is the churn so big?'. Now that we have a single source of truth our communication is happening light-years faster."
Ilija Stojkovski, CRO
HeyReach ($10M+ ARR)
"Understanding our revenue split across subscriptions and one-off invoices used to be a real pain. Now, we trust our dashboards, don’t have to cross-check four different systems, and can actually measure which channels drive real LTV.”
Glenn Miseroy, CEO
Expandi ($10M+ ARR)
“We had data scattered across Mixpanel, ChartMogul, Zendesk, and HubSpot, but combining it was nearly impossible. Now, we have live, reliable data accessible every day.”
Simon Pool, CTO
Rentman ($15M+ ARR)
"It used to take six hours of manual data entry every Monday just to get our weekly numbers. Now, we deliver actionable reports instantly.”
Tim Lorijn, CFO
Level.works
"We felt a loss of control because our data was inconsistent and hard to compare. Now, our unified dashboards let us easily track marketing and sales trends.”
Frans-Willem De Kloet, CEO
Ecochain
"We were managing data manually, disconnected from business outcomes. After Drilldown's analysis, it finally clicked – we could clearly see how a single strategic decision directly impacted the bottom line."

"After trying different tools for a year without success, Drilldown delivered the insights we needed in just 4 weeks. This new setup helps us track our business clearly, making it easier to reach our goals."
"What impressed me was how Drilldown turned complex analytics planning into a clear, actionable strategy. They understood our needs quickly and delivered a pragmatic roadmap that gives us a strong foundation for growth."
"Everyone looked at different numbers, making it impossible to agree on what truly mattered. The collaboration aligned us around shared data and opened our eyes to which metrics truly drive the business."
"Our previous data setup wasn't scalable, making data-driven growth hard. Drilldown built the solid foundation we needed, giving us the confidence to scale smarter."
.avif)
"We lacked a clear way to see the business numbers that truly matter. Drilldown built a dashboard that makes our key metrics easy to understand and use, helping us make better decisions and improve how we run the business."
"We needed dashboards that gave us the right insights in a clear and usable way. Drilldown delivered thoughtful, good-looking dashboards that provide the deep insights we need while staying easy to use."
