Gresham House Ventures makes £4.5mn investment into ARKK

Gresham House Ventures, a leading growth equity investor focused on backing software and technology-enabled businesses, has made a £4.5mn investment into ARKK, a leading software platform for the Office of the CFO.  

ARKK enables businesses to make highly accurate regulatory submissions up to 80% faster and at a fraction of the cost compared to using traditional consultants, replacing tedious, error-prone, repetitive tasks with AI-powered workflow technology. With international businesses facing a constantly evolving and increasingly complex tax and regulatory environment, ARKK’s platform has attracted over 1,000 customers internationally, including 65% of FTSE businesses. 

Gresham House Ventures is doubling down on ARKK, having made two previous investments in the business since 2019. The latest investment will build on ARKK’s continued commercial traction by expanding the product roadmap to address new regulatory reporting requirements, enhancing the customer experience, and scaling the sales and marketing function. This is another illustration of Gresham House’s long-term commitment to backing management teams’ growth ambitions, having recently led follow-on investments in defence IT provider SecureCloud+ and e-commerce platform Patchworks. 

The deal, made via the Gresham House VCTs, builds on Gresham House Ventures’ existing pedigree in the regtech space, following previous investments into event accreditation platform Accredit Solutions and digital content preservation business Preservica and it also follows a highly active period of deal flow, including new funding for specialist law firm Greenwoods Legal Services. 

Marieke Christmann, portfolio director at Gresham House Ventures: 

“ARKK is addressing a growing and increasingly complex regulatory challenge with a scalable, best-in-class platform. We have built a high level of conviction in the business over multiple investment cycles, particularly in the CEO and senior management’s ability to scale the platform and stay ahead of an increasingly complex regulatory landscape. This follow-on investment reflects our confidence in ARKK’s long-term growth trajectory and our commitment to supporting the team as a long-term partner. We are delighted to continue our partnership and to support ARKK through its next phase of growth." 

Jenny Himsley, CEO at ARKK: 

“We are delighted that Gresham has extended its support and commitment to ARKK as we enter the next phase of our growth journey. Gresham House Ventures has been a highly valued partner since 2019, and this latest investment reflects strong confidence in ARKK’s technology platform and longer-term vision. The additional funding will accelerate innovation across our Automation Platform, enabling us to deliver more advanced, scalable solutions to help businesses around the world simplify and manage increasingly complex tax and regulatory compliance requirements.”
