About

We build brands that grow and stand out

We have spent 25 years in-house at tech companies, owning the brand end to end alongside engineering: identity, product surface, and the copy that ties them together.

Copy is part of the design here, not something poured in after the layout is approved.

Testimonials

They said it better than we could

Cyril was always a dependable, creative force as our lead designer, but also went over and beyond by being a great thought partner, who proved to be extremely valuable in the early stages of building numerous products. I miss working with Cyril and would welcome an opportunity to work with him again.
David MarcusCo-founder, EchovoxCEO of Lightspark, former President of PayPal
He has the ability to use a very large set of software and technologies, making him a first choice if you need to do anything, from interfaces to commercial movies, that needs to create the “wow!” effect on end-users.

Brand is the strategy, identity and voice that make you recognizable. Product is where people actually use what you've built. Kerozene works across both so they stay consistent instead of drifting apart.
