Show notes
Ruben and Ramon van Aarle pull back the curtain on their journey through tax, technology and entrepreneurship. Real stories, not sanitised ones: how they built a tax advisory firm from scratch, what actually happened at the bar table where half the big decisions got made, and the f*ck ups it took to get here.
No polished success story. Just the anecdotes, the mistakes, and the lessons worth stealing.Brothers in Tax | Episode 7 | Random Businesses — The Good, the Bad and the Ugly
