Fix what's blocking you first. Build the engine second

    We diagnose and unblock first

    We don't start by designing the perfect system. We find what's blocking you right now and remove it. The vehicle needs to move — we can redesign the engine later. Execution beats strategy every time.

    We design the right setup

    Once you're moving, we design the structure that fits your reality — roles, responsibilities, and the right processes or rituals depending on whether you need consistent output or you're operating in high ambiguity where execution is still responding to strategic discoveries.

    We map your people

    We look at who you have and what they're capable of. Who fits the new structure, who needs development, who might not be the right fit anymore — and what to do about it honestly and humanely.

    We implement in iterations

    We plan in iterations and stay with you through execution. If needed, we don't just advise — we take a fractional role and do the work alongside you.

    We bring the right person in the room

    At any stage, if we feel a specific expertise is needed, we bring someone in. Not a team. The right person, at the right moment.

The team

Let's talk. No pitch, no sales. Just an honest conversation

Testimonials

When you’re growing fast, the problems stop being about customers and start being about people — hiring the wrong ones, promoting the right ones too late, managing a team that’s doubling before you’ve even figured out who you are as a leader. Mangrove has been with us through all of those moments. Not with frameworks or theory, but with real, hands-on support. I honestly don’t know what version of Lettly we’d be running today without them. Probably a worse one.

Jakub Orłowski
Co-founder & CEO, Lettly

Marta has been with us since we were 2 founders arguing over a shared desk. And three junior employees listening to those arguments. Ten years later, we’re 30+ and still calling her first when something important needs thinking through. She’s helped us navigate co-founder conflict, strrengthen and develope our managment team we actually trust, and make strategic calls we wouldn’t have had the clarity to make alone. Mangrove isn’t a consultant you hire. It’s the person who knows your company almost as well as you do (sometimes better than you) and tells you the truth without judgment.

Co-founder, Lettly

Entrepreneurship is a great journey, but it can easily get hectic. When it does, even easy situations turn out to be super difficult to solve and founders themselves often feel overwhelmed and lost . This was exactly when I started working with the Mangrove team. They provided me with ready-to-use solutions that quickly lead my company to visible results and, as important as business results, quickly put my mind at ease. If you got stuck in similiar situtation, those are probably your go-to people.

Working with Marta — despite her being genuinely warm — is not a pat on the back. It's research-based, precise, and deeply individual. She's like a surgeon: she analyzes, diagnoses, cuts, and stitches. Except the patient is an active participant in the operation. We came to Mangrove because co-founder collaboration is where many startups quietly fall apart. Marta helped each of us understand our own thinking and working styles, then helped us understand each other's. I learned things about myself and my co-founders I hadn't seen before. It strengthened our relationships, sharpened how we divide responsibility, and made our leadership team genuinely more effective.

I've referred several founders from our portfolio to Mangrove, and the difference it makes is visible. These are people under real pressure, and Mangrove's work helps them think more clearly, lead more effectively, and move faster. As an investor, I can spot gaps that equity and board seats can't fix — Mangrove fills exactly that space.
