Marshmallow’s Mission ?

We’re on a mission to make insurance more instant, affordable and inclusive by building the most tech-focused insurance company of our generation.

Since launch we have been the quickest growing insurtech in Europe. We are currently turning over more than $100m per annum, are valued at over $500m, have raised over $45m, and are signing up 10k new customers per month. We are one of the only UK based insurtechs to own our own insurance company – giving us total control of the entire value chain, from sign-up and pricing through to claims affording us the unrivalled ability to deliver an exceptional customer experience. We have a huge advantage over incumbents due to machine learning, automation, owning our own technology stack, comprehensive data integrations, seamless design and a fast, honest culture. We are a team of over 100 and counting, have a 4.6* Trustpilot score, and are championed by deep-pocketed investors who have backed the likes of N26, Spotify, Transferwise and Monzo. We have also been named one of London’s best startups to work for.

About Marshmallow

Engineering at Marshmallow As a tech-centric organisation, our engineers are fundamental to our success, and we’re incredibly proud of everything we’ve achieved so far ? We’ve created a fraud detection system to catch an increasing number of fraudsters in their tracks, along with a bespoke Customer Account web application to allow customers to self-serve for the majority of their needs - something unheard of in the insurance space! ? We’ve also built a unique bespoke risk engine, to accurately price one of the most diverse insurance customer bases in the world ? We affectionately call this system “Milkshake”, as it’s composed of hundreds of data points along with Machine Learning models, all blended together to produce a price for our wonderful customers, meaning that we can assess risk more fairly and comprehensively than ever before ? In 2021 we expect our customer base to triple, meaning that there are plenty of exciting challenges ahead. We will need to plan for growing volumes whilst also building new product features, continually looking for ways to automate processes to keep up with our ambitious growth plans ? We work in small cross-functional teams, meaning that everyone has the opportunity to take ownership of their work and make a big impact. However, our work is never siloed ? We work closely with designers, product managers, data scientists and other stakeholders to develop and improve the product roadmap, always keeping customer needs in mind. It’s going to be an incredible year and we’re only just getting started ?
