Arthur Hendriks.

Access the Bright Side.

I've always worked from the mind. A few years ago, I added the heart.
Now I combine both.

"What are the conditions that make the best work possible?"

Personal growth and professional growth have always been the same thing for me. Fundit is built on that. So is Três Bandeiras. Sacred Work Lab is where I'm exploring how far that goes.

I've worked on multiple sides of the table. Tax lawyer advising multinationals. WBSO and Innovation Box specialist. Startup co-founder at InvestID. Organiser bringing founders and investors together at the Global Entrepreneurship Summit.

With involvement over 100 Innovation Box rulings, I'm one of a handful of specialists in the Netherlands who combines WBSO experience and a tax law background with Innovation Box as a primary focus, specifically for tech and software companies.

I know what the tax adviser will say, the lawyer, and the founder, because I've been each one.

The mind I trained for twenty years. Portugal, being in nature, and a few years of going deeper added something. A different angle on the work I was already doing.

Spending time by the Atlantic, sharing houses with founders, cooking dinner together after long working days. I started noticing that where you work, who's around you, and what state you're in when you sit down influences the work more than anything on the desk.

That was the start of a more regenerative approach to living and working.

"First you change your environment. Then the environment changes you."

Four ventures. One thread running through them all.

01 / Venture ● ACTIVE SINCE 2024
Founder · Ericeira, Portugal

Três Bandeiras

An award-winning Coliving Residency in Ericeira, Portugal. A 1 to 3 month living and working environment for founders, conscious creators, and changemakers, contributing to something larger than themselves. We design the conditions where environment, people, and rhythm support depth, better decisions, and real contribution. A regenerative living lab, where co-living, retreat, and mastermind meet, built and refined together.

Fundit

One of a handful of specialists in the Netherlands combining WBSO, a tax law background, and Innovation Box as a primary focus, for tech and software companies. Involved in 100+ Innovation Box rulings and 1500+ WBSO applications. No cowboys. No juniors filling in templates. The kind of advice that compounds over time.

Investor Relations · Ecosystem

Advisory & Ecosystem

Over the years I've taught Innovation Box to tax advisers and accountants at SDU, mentored founders at Startup Bootcamp, Open House, and The Hague Tech, written for Silicon Canals, and co-organized events connecting startups and investors with Amsterdam Capital Week, Holland Fintech, and the Global Entrepreneurship Summit. The red thread: access to the right people, the right knowledge, and the next milestone.

Sacred Work Lab

A research practice into how the best work actually happens. Not only from the mind, but from intuition, the body, the state you're working from. And not by ourselves, but amplified in a shared collective field. Early stage, live, and open to the right collaborators.

"How you do one thing, is how you do everything."

What I'm building toward.

What are the conditions that make the best work possible?

After living in a few places in Portugal, I was looking for something I wasn't sure even existed.

I had spent a season in Ericeira, sharing a house with three world-class founders. We weren't in a program. We shared a place near the ocean and talked over dinner about what we were each working on. The work I did on my branding for Fundit that season was more than I could have done by myself. Because of who was around me, and where we were. When we each went our own way, it inspired me to find such a place.

I found the place, and we created Três Bandeiras. It's a place where the environment and the people around you do more of the work than you'd think. The Atlantic, nature, an active healthy life: not a backdrop, but conditions. And the body isn't separate from the work, when nature, rhythm, and real connection are designed in, the quality of thinking changes.

There's one more quest I'm starting to explore. As founders, we tend to work by ourselves, and mostly from the mind. Retreats taught us tools for accessing other parts of ourselves: the heart, intuition, other states of being. Business masterminds taught us the power of shared knowledge, a common goal, and a network of likeminded peers. I want to combine both these traditions for creating, by ourselves and amplified in a shared field. That's Sacred Work Lab.

If you're researching, building, or actively thinking about what the right environment does to the quality of working and living, I'd like to hear from you.

"Someone you want next to you when the stakes are high."

"I am able to recommend Arthur as a person who has profound knowledge and great abilities of modern business solutions. He's got a very strong work ethic and unparalleled analytic and problem solving abilities. His performance at InvestID was golden. He is not only a reliable and forward thinking Entrepreneur but also an inspiring team player. Arthur worked far beyond the call of duty. He most definitely shines in a fast-paced business development and business strategy environment. Definitely worth recommending and last but not least, Arthur will find a way to weather any storm with a smile :-)"

"Building something as meaningful as TB takes a special person. Arthur is that person."

"Arthur had the vision for Três Bandeiras before most people would even know what to call it, and then showed up every single day to build it into reality. He is the rare kind of founder who combines genuine visionary thinking with the discipline to execute on it, consistently, through every challenge. What makes him stand out is not just his entrepreneurial drive but his deep care for the people around him. He leads with warmth, fights for the mission with the heart of a lion, and creates an environment where others feel supported and inspired to do their best work. Building something as meaningful as TB takes a special person. Arthur is that person."

If something here resonated.
