Zilch, which claims to be the UK’s fastest growing FinTech, has appointed Boriana Tchobanova as chief operating officer.

Tchobanova joins from American Express Global Business Travel, where she served as chief transformation officer, leading the business’ post-COVID recovery and M&A activity – and paving the way for its multiple billion-dollar IPO in 2022.

Prior to this, she spent almost 15 years with American Express across multiple senior roles in strategy, transformation and operations, including as COO of the company’s digital business.

Zilch doubled revenues to £110 million for the year ending March 2025, marking a fourth straight year of 100% growth, with gross profit surging 143%.

The latest hire follows the addition of BlackRock director Mark Wilson to the board as a non-executive director.
