Help us build an everything-but-average insurance brand. Fit for the ones who step outside the norm. We back the ones who step outside the norm. People who find themselves on a different path, either by choice or by circumstance. The exceptions to the rules that others aren’t interested in serving. Those are the ones we want to back, in everything we do.

For the next three years, that means becoming the go-to insurer for people who are new to the UK. A huge cohort of people that the industry is not set up to support.

Not only do we cater for their immediate needs (fairer, cheaper prices), we also go above and beyond to make them feel seen and heard in everything we do. Location

Data Engineering About Marshmallow

We started Marshmallow when we found out how unfair insurance prices are for people who move to the UK. All because the industry hasn’t given this huge cohort of people a second’s thought, and isn’t set up to price them properly. We saw an opportunity to do things differently, so we made it our mission to back the ones who step outside the norm. Since we started, we’ve helped 100,000s of people get a fairer deal on their car insurance. Using technology, we serve people that are often overlooked by financial services companies, solving important problems for people who need it most. How we work

We’re really proud of the culture we’ve created. We push for progress every day, because we know that we’ll only hit big milestones by taking lots of smaller steps. We’re always open to helping our team mates, sharing our ideas, experience and knowledge to solve problems together. We take risks, think creatively and experiment relentlessly to meet our customer’s needs, and never pass blame when things go wrong. We encourage people at all levels to take ownership of their work, and to be bold in challenging how we do things. Everyone has a voice and the opportunity to make an impact.
