About the Company

Company mission

Making it simple and fast to uncover opportunity with consumer data.

Attest is a B2B SaaS platform that simplifies consumer research. Businesses are constantly seeking new ways to understand trends, grow in new markets, and explore innovations. However, 99% of the questions businesses would love to explore go unanswered. The steps required to launch a survey have typically been cumbersome. Attest has built a self-serve platform that allows companies to ask targeted questions from a wide range of audiences.

The traditional research market is worth $76 billion, and yet it only serves a fraction of those who would benefit from fast and reliable consumer insights. Attest is currently focused on larger customers such as Heineken, Boots, and Samsung, while also seeing demand from smaller players such as Monzo and Nutmeg, showing the size of the opportunity.
