SaaS platform giving leading companies confidence in their tax and regulatory reporting

ARKK is a UK-based Software as a Service provider that digitises regulatory reporting, which is increasingly required by authorities worldwide.

The business recently launched ‘for:sight’, a new software platform that simplifies burdensome processes, reduces the potential for non-compliance, and frees up the finance function to focus on value-adding tasks.

Having first backed ARKK in May 2019, our investment now totals £7.2m.

Investment rationale

We invested to support ARKK’s plans to invest in sales, marketing and new product development, in order to accelerate its strong position in the UK tax and regulatory reporting market.
