Salary benchmarks
Otta's take
Sam Franklin
CEO of Otta
For many ordinary people, insurance can be inaccessibly expensive. Marshmallow solves this problem by using data and technology to offer fairer coverage for car and van owners.
Car insurers generally quotes drivers according to population data, and many drivers are overcharged due to age and demographic. By leveraging data and proprietary technology, Marshmallow can offer more accurate and personalised quotes delivered in minutes, meaning lower fees for drivers. Naturally, this approach has proven popular, with Marshmallow garnering impressive reviews and accolades since it first launched.
The insurtech space is becoming increasingly competitive, and more and more tech companies are moving into the car insurance space, so the company is currently looking to expand into other insurance areas. Marshmallow’s unicorn status is a clear indicator of the company’s ongoing success and scalability, and will help to facilitate this diversification.
For now, the company is focused on helping those outside the norm, such as those who have uprooted their lives and moved to the UK. But in the future, it hopes to expand to any group of people who are unfairly marginalised and whose problems Marshmallow is uniquely positioned to solve.
