Who We Are

20181001 125141-crop-med-3

Overleaf is a startup and social enterprise that builds modern collaborative authoring tools for scientists — like Google Docs for Science. Our primary product is an online, real time collaborative editor for papers, theses, technical reports and other documents written in the LaTeX markup language.

In our nine years since launch, Overleaf has seen rapid adoption across science and research, and now supports a community of over ten million authors from over 180 countries worldwide who’ve created over 87 million documents using our services. This community includes major institutions such as Stanford and Caltech, with Overleaf becoming an integral part not only of research collaborations but also of undergraduate teaching.

Overleaf is also making the journal submission process smoother for LaTeX users across many academic publishers; a number of large international tech companies and labs are using our enterprise solutions; and we support educational outreach through our volunteer Overleaf Advisor programme, which has over 300 members.

Digital Science UK Limited (formerly Writelatex Limited), the company behind Overleaf, was founded by two mathematicians who were inspired by their own experiences in academia to create a better solution for scientific collaboration and communication. Now we are a team of over thirty, based mainly in and around the UK and in the US.

We are also part of the wider Digital Science group, who have helped us grow into the company we are today. Digital Science have supported and invested in Overleaf since 2014, and have a mission to help make research more efficient so there’s more time for discovery.

Our Aims

Why did we create Overleaf? To address problems that we experienced ourselves when writing papers collaboratively, and by doing so, make the power of LaTeX accessible to all scientists and technical writers, at all stages of their career.

Most of the world's technological and medical innovations began with a scientific paper. There are over two million scientific papers published every year, and many more technical reports and presentations. Scientists in academia and industry spend a lot of their time writing, reviewing and publishing these papers; that's a lot of admin & paperwork tasks. We saw a way we could help save time on these tasks, making the whole process of academic collaboration easier and more effective.

Going beyond academia, society increasingly looks to science for solutions to today’s most pressing social challenges, and if we’re going to face up to complex health issues, an ageing population, and the digital transformation of the world, we need science that is faster, more open, more trustworthy, and more meaningful to citizens. We’re helping to make that possible.

                              I'm a born and bred California girl from LA, but have been living in Madrid, Spain for over a decade. Having come from a background in higher education and B2B tech marketing, working at Overleaf is a dream come true! I´ve lived in 8 countries, play the piano and am a self-proclaimed food and wine critic (much to the annoyance of my friends and family).

                              I’m an Information Systems graduate, with an intensive background in administration. I currently live in London. In my spare time I enjoy creating new experiences with my family, listening to music and adding content to my online podcast (The Bad Parents Podcast). When I feel inspired, I also like to create and when possible, perform my spoken word/poetry. Hoping to grow and be a major attribute to the Overleaf Team.
