Our take
Up to 90% of company profiles in traditional customer relationship management systems (CRMs) are incomplete or out-of-date, causing missed sales opportunities and wasted time. Affinity exists to change this state of affairs, using AI to analyse a company's communications and interactions to provide the most accurate profile possible, powering sales and excellent customer relationships.
While other modern CRMs exist, few of them are able to automate data input on the scale of Affinity, which has processed around 20 trillion emails and hundreds of thousands of calendar events to date. It also focuses on industries that are underserved in the CRM sector, including investment banking and real estate. This has grown it a client base of more than 3,000 customers including major enterprises such as Bain Capital Ventures, Nike and Twilio.
Affinity is focusing on expanding its sales, marketing, and engineering teams to grow its customer base and develop new products. As companies look to both improve the performance of their sales teams and reduce costs in manual data entry, Affinity's product is likely to remain extremely popular.
