Entrepreneurs. Marketeers. Investors.

“MARKETING & SALES ARE KEY DRIVERS IN EARLY-STAGE INVESTING.
ESPECIALLY WHEN SCALING IMPACT.”
Xavier Sarras

30 years of building, scaling, and exiting businesses, 10 years of angel investing.

Xavier is an established entrepreneur with a 30-year track record of founding, scaling, and exiting businesses through marketing & sales. When he got into Angel investing 10 years ago, he quickly realised that his commercial acumen made him a valuable addition to any technical founder team’s cap table. Today, he is on the board Sigma Squared Society, a network for ambitious founders under 26. He holds a non-executive role at NewNow, a data-driven consultancy. And he is the advisor to a multitude of start-ups.
