Before you work with us, understand what we stand for
Why did we build this?
99% of all businesses in Europe are SMEs. They are the ones flexible enough to innovate, agile enough to change direction, and close enough to their communities to build something that lasts. And most of them are doing it without the professional support that the complexity of their job actually demands. We built Mangrove to change that.
What world do we believe in?
One where founders don't have to choose between their ambition and their wellbeing. Where professional support for founders is held to the same standard as any other critical discipline: rigorous, accountable, and built around who they actually are.
How do we show up every day?
become the first call a founder makes — when something is broken, when something is working, when the next move isn't clear. We bring advisors who see what's impossible to see from the inside, and implementors who stay until it's done. Not as a service. As a permanent part of how you build.
Our values
Radical Candor
We are honest because we care — not in spite of it. We hold founders to the standard their ambition demands, and we protect the human being behind the founder with the same intensity. Hard truths, delivered with respect. Always.
No Ego
We hold ourselves to the same standard we hold our founders to. We take feedback, we learn, we don't get offended. We try to be a little better every single day.
Clarity
We cut through the noise to give you a clear next step and a decision you can act on immediately. We separate intuition from facts, personal reality from business reality, and options from opinions. You leave every conversation knowing exactly where you stand.
And we joke. A lot.
Our mentors and advisors are human beings first. We genuinely love what we do — and we don't take ourselves too seriously while doing it. We laugh a lot, because it turns out humor is an excellent coping strategy when things get hard. You can relax here. You are among equals.
Everyone in this room has been in the trenches
No juniors. No theory. No one learning on your time.
Every person at Mangrove has spent years doing the actual work — building companies, leading teams, coaching high achievers through the hardest moments of their careers. We brought them together because founders deserve people who understand what it actually takes. Not from a book. From experience.
Anna Harris
She has helped grow two companies from early commercial stage to $100M-range exits, and advised 5+ more — from bootstrapped startups to public enterprises. Her edge is connecting all the revenue dots: GTM strategy, international expansion, and building the teams that execute it. She has lived and worked across 11 countries and built growth engines in many of those markets.
Jacek Gabanowicz
Over a decade of building sales pipelines and GTM systems for SaaS companies across European and global markets. He has since moved to where sales and AI intersect — building autonomous systems that generate revenue, not just activity. If your growth problem is a sales or GTM problem, he has already solved a version of it.
Joanna Andryszczak
She started her career in investment management, spent years on boards and in senior leadership at investment funds and financial institutions, then pivoted to coaching and leadership development. That combination is rare — she understands the pressure of high-stakes financial decisions from the inside, and knows how to help leaders perform under that weight. Over 10 years of coaching, mentoring and training, with a background that gives her instant credibility in rooms where the numbers matter.
Joanna Gawlik-Dziadoń
13 years of business and team coaching, with a background that spans banking leadership, organisational development, and conflict mediation. She works at the intersection of individual and team — helping managers stop functioning as a collection of individuals and start operating as a unit. For founders, that means one less thing to carry alone.
Katarzyna Cicha
A decade building communication functions for global companies like Wienerberger and Lafarge, combined with a deep background in neuropsychology and cognitive science. At Mangrove she leads our diagnostics — using psychometric and neurobiological tools to map founder dynamics and team health. She turns complex organizational data into something founders can actually act on.
Katarzyna Kamińska
She has co-founded a tech startup, led business development for an AI software house, and managed regional marketing for Philips across 18 countries. What she's actually best at is building the systems that make revenue predictable — the processes, the team alignment, the operational backbone that founders keep postponing because they're too busy putting out fires.
Magda Olczak-Nowicka
Former Managing Partner with a decade in VC — building and managing funds backed by PFR Ventures and mBank, leading investments from pre-seed to Series A, sitting on supervisory boards. At Mangrove she works with founders who are preparing to raise — pressure-testing business models, sharpening fundraising narratives, and building the operational structures investors actually want to see.
Małgorzata Kubisiak
She has trained 150+ managers and supported founders through more than threefold growth in headcount. She specialises in leaders stepping into management for the first time — helping them build authority, find their style, and stop losing their best people in the process. Her background spans HR, organisational development, and business coaching across both corporates and scaling startups.
Marcin Zaremba
CPO and Head of Product at Allegro, Synerise, PizzaPortal, and iTaxi. Former Google Product Strategy Expert. He specializes in one thing: making sure the product roadmap actually serves the business, not the other way around. He works with founders who are building fast but shipping features that don't move the needle.
Marta Borkowska
Over the last five years she has worked with 200+ founders across Europe — through scaling, conflict, succession, and everything in between. She built HR functions from scratch in startups scaling past 100 people, and holds a PhD in the psychology of exceptional achievement. She founded Mangrove because she believes founders deserve significantly better than what the ecosystem currently offers them.
Nick Kenn
He has taken two technology businesses to IPO and scaled others from $100M to $500M across consumer tech, AI, and global marketplaces in Europe, Asia, and the US. He works with founders navigating hypergrowth and with Private Equity on value creation. From 0-1 product launches to M&A and turnarounds — he has been in every version of that room.
Piotr Kozłowski
He has built financial infrastructure for LOT Polish Airlines, G2A, and FRU.PL, with a background in corporate banking at Raiffeisen and derivatives at Credit Suisse. He specializes in payment orchestration, fraud prevention, and international cash-flow. He also bridges traditional banking and the crypto ecosystem — useful when your payment stack is more complex than your product.
Przemek Dybek
Built his career at EY, Capgemini, and PepsiCo. He has managed large-scale IT transformations and prepared companies for private equity exits. At Mangrove he does one thing above all: strips away the noise and tells you exactly how your business makes money — and what needs to change before it can scale.
Radek Kropielnicki
15 years in healthcare and pharma at Teva, GSK, and Sandoz — managing $90M portfolios across 13 markets. He led one of the most successful product launches in Europe in his sector, then moved into health-tech sales. If your business operates in complex, regulated environments or your B2B sales process needs rebuilding from the ground up, he has done it before.
Slawomir Walczak
He took Tylko from a 6-person startup to a 210-person company valued at nearly 700 million zł — staying hands-on in the code the entire way. He has been CTO at multiple startups since, including AI ventures backed by teams from NVIDIA and Meta. He sits at the intersection of technology, product, and business in a way most tech founders spend years looking for. He is what building actually looks like.
Tarek Younis
15 years scaling revenue and operations at Uber, Delivery Hero, and Cisco. He has led sales across Northern and Eastern Europe and stepped in as Interim CEO for tech startups that needed someone who could run things, not just advise on them. He sits at the intersection of product, delivery, and sales — and he builds the bridge between them so growth doesn't break the organization.
