📍 Sofia (Office-first)We believe in the everyday hero — those who have the courage to follow their passion and the determination to realise their dreams. Small business owners are at the heart of everything we do, so we’re creating powerful, easy-to-use financial solutions to help them run their businesses. With a founder’s mentality and a team-first attitude, our diverse teams across Europe, South America, and the United States work together to ensure that small business owners can be successful doing what they love.
