At ARKK,
we're on a roll
For over 15 years, ARKK software has
been the secret sauce in successful
tax and finance departments.
Chief Executive Officer
After starting her career at KPMG as a graduate chartered accountant, Jenny moved into the fast lane of the financial services industry, becoming one of ARKK's first customers back in 2010. She joined ARKK as part- time CFO in 2016 and became CEO in 2022. Away from work you will find Jenny ferrying her two girls to swimming galas and equestrian events, and maybe even attempting another transatlantic sailing trip!
Chief Technology Officer
Co-founder Roi has been with ARKK since day one. He was inspired to build ARKK by his time in the military, and then by his subsequent experiences as a technical architect in the asset management and insurance industries. Roi’s impressive kit-bag of skills extends from coding to strategy. Look to the skies if you want to catch him off duty – he’s a qualified pilot, as well as a committed family man and a passionate lifelong learner.
Chief Financial Officer
Numbers man Clive began his career with Fairfax International Holdings in Dublin back in 2008. He joined ARKK in 2018, inspired by an affinity with our values and ambitions. After overseeing two funding rounds and recording double digit growth, Clive has made the CFO role his own. As if that wasn’t enough, he also heads up our Digital Tagging Solutions. And yet he still finds time to enjoy cooking, cycling, rugby and traveling. Though not necessarily all at the same time.
Chief Customer Officer
In her ten years at ARKK, Danielle’s assembled a formidable team of customer success superstars. Responsible for Customer Success, Product Support and Implementations, Danielle’s team is laser-focused on making sure ARKK customers get the very best value and experience from their ARKK tech. With a background in Law and a passion for fitness, Danielle still finds time to enjoy the good things in life: food, travel and adventure.
Chief Sales Officer
Sales and marketing expert Clare brings 25 years of experience to the ARKK mix, having worked in FMCG, advertising, and consulting as well as fintech, with much of her time focused in Tax. Clare’s got a great track record in scaling businesses – she grew her previous company from £300K to £25M in just five years. Alongside heading up ARKK’s sales and marketing teams, Clare’s at her happiest when she’s hanging out with her husband, kids and friends and family, especially if there’s a rugby match or a cold beer involved.
