The first thing we built together lasted three days. We were 11 and 12, with a garage and a bicycle workshop. We learned something no degree teaches: what it feels like when the business is yours.
We have been working together for more than 25 years. Luis started in payroll advisory at 16 and is still there; Guillem built an online advisory firm, sold it, and never stopped. In 2018 we brought both worlds together and Tax Factory was born.
We built it because we know what it feels like to be alone with your business and have nobody explain things clearly.

CO-FOUNDER · TAX AND ACCOUNTING
The firm’s growth engine
I grew up in my father’s firm. I was a terrible student and lost seven years doing everything except working. At 29 I ended up sweeping a warehouse in San Sebastián for 300 euros a month. That is where I really started learning.
