We are the most comprehensive IR35 compliance solution available to hirers, agencies, accountants, service providers and contractors. We deliver fast and accurate artificial intelligence (AI) driven online assessments, with access to an extensive range of IR35 support services, for complete protection in one place.
Our solution features Renoir, our AI-powered virtual employment lawyer, and a key component of your IR35 compliance process.
Renoir’s AI capabilities enable him to carefully evaluate the contextual importance of each factor impacting IR35 status, as required by employment case law.
Without Renoir, an employment status lawyer will charge you for 2-3 hours’ work, and turnaround time may take a week. Renoir delivers a free comprehensive assessment within 15 minutes.
Renoir is self-learning, continually collating market data and trends. Having Renoir on your team also provides big data insights from the thousands of tests conducted each month, helping you to better manage IR35 risk.
