Dorota Kosiorek

I'm a GTM and Customer Success leader with ~15 years of experience across AI/SaaS, strategy consulting and transaction advisory.

Most recently I spent five years at Tractable.ai, an AI scale-up selling to large insurers. I started as Head of Engagements in Poland and grew into Director of Go-To-Market, Customer Success & Partnerships for EMEA. For about 1.5 years I also covered the US. I led a remote team of 5–10 across more than five countries, including managers, CSMs and solutions managers. I was also the hiring manager for over four years. We looked after a $5–10M portfolio: 15–20 enterprise accounts and more than 100 subscription customers. We kept ARR retention at 95%+ in 2024–2025 and brought in new ARR at 120% of target. My work covered the full customer lifecycle: presales and AI pilots, business cases, pricing and negotiation, onboarding, adoption, renewals and expansion. I also owned our EMEA GTM strategy and the partner ecosystem. My team was the best performing in the company. The thing I'm proudest of is that people told me I was the best manager they'd had.

Before Tractable I spent ten years at PwC and BCG. At PwC I did audit and forensic work, then led due diligence projects in retail, TMT and healthcare, and managed teams of 4–8. At BCG I worked on cost and process optimisation for large European retailers. I passed the ACCA exams. That finance background still shapes how I work: I think in value drivers and numbers, and I build business cases that hold up in front of a CFO.

I'm also an ICF Associate Certified Coach and a certified brain coach. Since 2024 I've coached leaders and founders on focus, decision making and performing well without burning out. It's the same approach I take with my own teams: high standards, honest feedback and real support.

I'm looking for a leadership role where I can make a real impact in a business that excites me. That could be Head or Director of Customer Success, Head of GTM, COO or an operator role. I'm open to full-time, fractional, interim or part-time. I'm most drawn to sport, health, wellness, beauty, education, entertainment and tech, but a good role matters more to me than the industry. I'm based in Poland and open to work remotely with teams in Europe and US, or in a hybrid setup in several EU countries (Spain, Italy, France, Portugal, Germany, Netherlands, Switzerland, Austria, Denmark, Sweden). I speak Polish, English and Spanish.
