Sherpa at Mandata

Clive O’Sullivan

Clive is our Sherpa at Mandata, where he is working on key growth opportunities and strategic value creation projects.

Originally from a farm in Australia, Clive started his career as an accountant in Melbourne, predominately working with founder-led SMEs. He loved working with entrepreneurs to help grow their businesses but wanted to help them beyond just the finance function. This led him to move to London in 2017 to undertake an MBA before joining Tenzing as a Sherpa so that he could help entrepreneurs scale their businesses.

Clive’s first portfolio company assignment was at Ticketer, where he supported the Founder and CEO from 2019 to 2021. He worked on the acquisition of FARA, helped deal with the challenges faced by COVID and completed a commercial analysis of Ticketer’s products.

Clive is now working closely with Mandata’s Leadership Team across several strategic projects, including completing a strategic review of its marketplace product offering and supporting the Directors in executing growth opportunities.

The Sherpa induction, monthly training, weekly mentoring, and day-to-day work supporting the CEO have made me challenge and question the frameworks I learned in business school. No amount of frameworks or textbook models will really grow a business; the Sherpa Programme has shown me that scaling a business requires you to continually question things, genuinely care for your customers and products and ultimately it is your people that matter the most.”
