What clients say

Ryan Manuel
CEO, Bilby AI
Melisa joined us as Fractional Head of Data and took full ownership of the domain - strategy, roadmap, infrastructure, and the team. She advanced the data foundation our AI engines run on, and hired the people to keep it running before stepping out. Rare to find someone that strategic who is also hands-on. She’s also super commercial, and easy to deal with to boot. It was a delight to work with Melisa and I recommend her wholeheartedly.

Michael Kowalzik
Managing Director, Brera Serviced Apartments
After we met, the decision to work with Melisa and Jann was easy. Together they bring hospitality know-how, engineering and analytics.
They architected our central data warehouse and built the connections into apaleo (our current PMS), our legacy Sihot system, and DATEV for cost data, encoding the business logic and mappings we use internally into the models behind the reporting.
The result is that we now trust our numbers. We are on top of revenue, costs and business on the books at all times.
They have also helped set up an MCP connection between our warehouse and LLM assistants, so we can ask questions of our data in plain language.
Both of them worked seamlessly with our team throughout!
I can only strongly recommend Melisa for similar datalake/dataware house projects. It was a pleasure to work with her and her team mate Jann.

Tina Pfützenreuter
VP Growth & Data, STAYERY
We hired Melisa to audit our data setup. She came back with an architecture and roadmap convincing enough that we hired her to build it.
She connected apaleo, our PMS, and our marketing channels into a central warehouse, then built the dashboards we now run on: revenue on the books, guest insights, marketing and B2B sales performance, an arrivals monitor, and a company snapshot that lives on a big screen in our office.
From our reservation data she also established a single, clean and actionable view of both our corporate clients and our individual guests - using machine learning to recognise the same guest across separate bookings. She knows where AI actually helps and where it doesn’t.
Throughout the partnership she has been a trusted sparring partner. She understands our business and our organisation, and argues objectively for what is worth building and what is not - even when that means talking us out of something.

Valerie Hennsen
CEO & Co-Founder, VEGDOG
What made Melisa such a valuable part of our team went far beyond her technical expertise. She is exceptionally clever, a true high performer, and has an impressive ability to grasp complex topics very quickly. She never just waited for a question or task to come her way - she consistently brought her own ideas, analyses and hypotheses to the table and challenged us to look deeper.
I experienced this particularly in our calls together. Whenever we were trying to get to the bottom of a difficult business question, Melisa was incredibly creative in figuring out how we could use data to find an answer. She would think beyond the obvious metrics, challenge assumptions and come up with new ways to approach a problem. I really valued these conversations because she didn’t just provide data - she helped us understand what was actually happening in the business and why.
When Melisa started working with us, we were selling across multiple channels - Shopify, WooCommerce and Amazon - but had no reliable way of seeing the full picture. Our teams were spending far too much time manually pulling numbers together. Melisa changed that. She designed and built the data lakehouse that brought everything into one place, followed by the dashboards that we now rely on for both internal decision-making and external reporting.
What this unlocked went far beyond reporting. She supported us throughout our fundraising process, and her work fed directly into product launch decisions, inventory planning, forecasting and detailed margin calculations.
Melisa was also someone we could always rely on. She was incredibly responsive, always available when we needed her, and consistently followed through on what she promised. At the same time, she always had the bigger picture in mind. Once the setup was in place, she was actually the one who encouraged us to bring the data function in-house rather than making ourselves dependent on her. She helped us hire a senior analyst, ran self-service analytics training for most of the company and handed everything over with thorough documentation that we still use today.
Throughout our time together, Melisa never felt like an external consultant. She worked like one of our own, genuinely cared about what was best for the company and actively looked for ways to save us cost and effort rather than billing us for every small thing.
We were extremely happy to have Melisa with us. She was a real enrichment to our company - professionally, because of the quality of her work, her analytical mind and the energy and creativity she brought to solving difficult problems, but just as importantly on a human level. She is someone I could always count on and someone I genuinely enjoyed working with.

We brought Melisa in for a short, focused engagement. She got up to speed on our business fast, gave us clear and honest advice, and was easy to work with throughout. I’d recommend her without hesitation.
