Beowave was more than a consultant; Mariusz was our acting CTO during a critical growth phase. He didn't just give advice; he rolled up his sleeves, mentored our junior developers, refactored our backend for scale, and helped us hire two senior engineers. His blend of deep technical knowledge and business strategy is incredibly rare and was a complete game-changer for us.

His due diligence reports are the gold standard for our firm. He has a unique ability to go deep into a company's tech stack and codebase and translate his findings into clear, actionable business risks and opportunities. When Beowave gives a technical architecture the green light, we know our investment is on solid ground. We trust his judgment implicitly.

We had a complex product roadmap but were struggling with execution. Beowave was instrumental in turning that around. Mariusz has helped us implement a true agile process, managed our development sprints, and even wrote critical parts of our API himself. We launched our MVP on time and on budget, which simply wouldn't have been possible without his hands-on leadership.
