Inflow Partners is a full-service marketing agency that helps local small and mid-sized businesses attract more customers and grow in a structured way.

The idea came from my experience with Client Lab, where we offered top-notch software that everyone was very enthusiastic about, yet projects still failed because clients simply lacked the time to put in it to work for them.

Working with companies in sectors such as beauty, wellness, healthcare, finance, automotive, hospitality and retail, I saw that many owners had no time or in-house expertise to build a consistent marketing approach.

Inflow Partners takes this off their hands, combining strategy, content, advertising, websites and marketing automation into one coordinated approach that delivers measurable results.

Our vision is to give local businesses the same professional marketing as larger organizations, with a personal approach and a clear focus on growth.

Client Lab was founded after the success of ActiveCampaign Manager, building on extensive experience in managing and growing contact lists.

Working with a wide range of companies, I saw that many struggled with disconnected tools and fragmented processes across marketing, sales, customer management and daily operations.

Client Lab is an all-in-one marketing and sales software platform that brings these functions together in one place, with automation built in to streamline key business processes and save time.

Our vision is to make professional software and process improvement accessible to organizations of all sizes, from small businesses ready to scale to larger companies looking to increase efficiency, drive revenue growth and enhance operational performance.

ActiveCampaign Manager is a dynamic company with extensive expertise in setting up, managing, and scaling ActiveCampaign accounts.

Our vision is to make marketing automation accessible to every organization, from solo entrepreneurs poised for growth to large enterprises seeking to optimize their processes.

By combining the power of ActiveCampaign’s marketing automation software with our tailored services, ActiveCampaign Manager ensures a smooth, effective, and affordable start to (email) marketing automation.

In this role, I was responsible for small-scale testing to troubleshoot production issues, as well as conducting initial experiments as part of New Product Introduction (NPI) protocols. This included first-time pilot-scale runs, evaluating operator procedures, and analyzing downstream processing of the product. A key aspect of the work was data analysis, interpreting experimental results to identify process improvements and ensure successful scale-up. All activities were performed under GMP conditions within a clean room environment.

Techniques used: GMP-compliant operations, clean room procedures, data analysis.

In various research and development projects, I was responsible for setting up and executing fermentation experiments, process optimization, and scale-up activities. I worked on both lab-scale and pilot-scale setups and was actively involved in tech transfer and troubleshooting. Data analysis played a key role in evaluating experimental results, optimizing process conditions, and supporting decision-making. As a lab manager, I ensured smooth daily operations by coordinating maintenance, managing supplies, and continuously improving lab workflows and safety standards.

Techniques used: (fed-)batch fermentation, HPLC, NH₄ and glucose analysis, precipitation, centrifugation, data analysis.

In preparation for my role as an email marketeer, I completed an in-depth training in ActiveCampaign. This program gave me a solid understanding of marketing automation, email campaign strategy, and customer journey building, equipping me with the tools to create effective, data-driven email marketing solutions.

I completed the NIMA Marketing program, which provided me with a strong foundation in strategic and operational marketing. The course deepened my understanding of market analysis, branding, customer behavior, and communication strategies, equipping me with the skills to develop and execute effective marketing plans.

I studied at Rotterdam Polytechnic College, where I developed a strong foundation in both technical and analytical skills. My time there was shaped by hands-on learning, collaboration, and a focus on practical problem-solving, preparing me to bridge the gap between theory and real-world application. It was also where my passion for technology, data and innovation began to take shape.
