You're building something bold for people, planet, and the future. MaSí is your solid partner here to help you grow without losing your soul.

Ready for your impact to stomp louder?

Doing good shouldn't mean running on empty…

You've got your idea. Maybe even a product.
A few wins, maybe a grant or two under your belt.
But things are getting… messy.
Your days are full —but you're unsure what is actually moving the needle for your business.
You're building to make an impact, but survival mode kicked in. And your motivation is suffering.
Grants?
Customers? Investors? You're stuck between chasing money and proving you deserve it.

Arrow pointing at content below Scaling’s starting to feel like scrambling.

Maybe you tried the typical growth playbook.
Too salesy, too extractive, didn’t quite fit.
Maybe you’ve gone it alone. And now it’s overwhelming.
Too much to do. Not enough cash. No clear path.
No one to share ideas with, challenge you, or keep you grounded.
Sounds like me Sounds like the founders I back

Meet the human behind the Elephant

Ciao, I'm Isa 👋

I spent years helping traditional businesses scale — until COVID hit just 2km from my home in Italy. Supporting grassroots impact orgs through that chaos was my wake-up call.

Since then, I’ve helped 100+ purpose-driven founders:

  • Arrow Break into new markets
  • Plant Build teams that actually like Mondays
  • Bean Escape the grant trap for sustainable funding

Now I want to help you do the same.

That’s why I created MaSì – built on what I know actually works from leading accelerator programs in 20+ countries.

Asterisk

Why I am not just another advisor

  • I’m impact AND business first. I’ve learned from the big players and helped founders across industries. Now let’s make it yours — mission- led, scrappy and serious about results.
  • I’m a generalist with 10+ years across Sales, Ops, Community, and HR — so when I advise founders like you, I can see the full picture and meet you where you are.
  • Building with impact is a wild, emotional ride — and I’m here for every twist and turn. I bring creativity, smart moves, and a kind, can-do spirit to help you navigate it all.

Questions?

What languages do you offer your services it?

I’m fluent in Italian, German, and English—and my Spanish is good enough to get things done too.

What kind of topics can we tackle in Growth Lab?

I’m a generalist, so just call me when things get messy. Fundraising, go-to-market, expansion, company building—strategy ties it all together.

What kind of topics can we tackle in Grounded Growth?

We kick off with a 1:1 session to set your goals and priorities. From there, we can tackle fundraising, go-to-market, market expansion, company building, team design, positioning & messaging, business model & pricing, partnerships, and even founder mindset.

Do you offer access to founders network or communities?

My network is your network. I’ll connect you with people and communities who can help you along the way. A warm introduction can make a big difference. If you’re a community or network looking to collaborate, send me a message at hi@masi-growth.com.

What founder stages do you support?

From idea or concept through pre-seed to seed. I love working with early-stage founders because this is when strategy, focus, and the right decisions have the biggest impact on shaping a successful venture.

Does it matter where I’m based for your support?

Not at all. I’m based in Europe, but I love working with:– Founders outside Europe aiming to enter European markets (I focused on International Growth at Google) – Founders from emerging markets (parity pricing available — just drop me a note at hi@masi-growth.com) – Incubators and accelerators running multi-country programs (I’ve handled complex, international programs and funders)

I don’t have a clear business idea yet (or I have a few). Can you support?

Absolutely. I can help you analyse your ideas strategically and cut through the clutter to find what’s worth pursuing.

I am a nonprofit. Can you support?

For sure! I’ve worked with nonprofits and get the challenges—drop me a line at hi@masi-growth.com, and we’ll see what we can tackle together.

I cannot currently afford your services. Do you offer scholarships?

I’m all about access! Just drop me a note at hi@masi-growth.com and include: – Your company status/legal form (founded, in founding, or not founded yet) – Any government benefits you’re receiving (like ALG 1 in Germany)
