About Crossing Waters
Product and sales leadership in one team
Crossing Waters is a product and Go-To-Market advisory for cybersecurity companies, based in Dresden, Germany, and working with clients across Europe, the USA and the UK. We have led product, sales and marketing organizations, not just advised them.

How it started
Crossing Waters started in Los Angeles. Our founder Felix Rosbach was advising a client on product-market fit, and over dinner, somewhere between the main course and dessert, the conversation turned to why companies actually struggle to succeed in the market. Usually it is not a strategy problem. It is the moat between departments: product, marketing and sales each defending their own territory instead of pulling together. Selling across the Atlantic makes it harder in both directions, with European companies landing in the USA and the other way around.
Somewhere in that conversation the idea came up, half-joking, that crossing those waters, the moat inside a company and the ocean between markets, is a business of its own. Something about it stuck. And if you do it properly, there is no halfway version: either you take on the whole process, or you do not do it at all.
That is still the premise today. We do not stop at Go-To-Market. We work on positioning, product strategy, vision and product marketing until they pull together, and on the processes and tools behind them, AI included, so it sticks. The picture above is from that evening.
Product success is all about the system you build around it.
Crossing Waters
Product success comes from a clear process, a system that keeps improving itself, motivated teams and real alignment. Not from months of internal debate or hiring your way out of a problem.
Whether you are entering a new market, launching a new product or rethinking your strategy, we give you fast access to product, sales and marketing experience, backed by a real network and channel access. We stay until it is stable, and help you build the team that carries it from there.
