Company Summary:

Laronde is pioneering a platform that offers a completely novel way of modulating human biology via Endless RNA™ (eRNA). eRNA is a uniquely engineered RNA that can be programmed to express diverse proteins inside the body. Laronde is rapidly scaling to support the development of multiple programs across many disease areas. 

Laronde was founded in 2017 by Flagship Labs, the innovation foundry of Flagship Pioneering. Laronde has a highly collaborative, dedicated culture, driven to achieve our vision of “making eRNA an essential class of medicines to everyone, everywhere”. To learn more, please visit the company’s website at
