Mateus Quelhas is Chief of Staff at Alloy's One Health Studio. He holds dual degrees in Food Science and Engineering from the University of São Paulo (Brazil) and ONIRIS (France), and an MSc in Strategic Marketing from Cranfield University in the UK.

His career started in new product launches and startup growth, helping early-stage businesses scale globally. He moved into corporate venture building, corporate venture capital, and business strategy. He later served as Chief Operating Officer at a business consulting firm within ACE Ventures, one of LATAM's top venture capital firms, where he led teams across more than 500 client engagements in life sciences, pharma, agriculture, technology, and consumer industries, working with companies including AstraZeneca, Unilever, Bayer, and BASF.

Mateus believes the best founders are fluent in both languages: the speed and resourcefulness of a startup, and the rigor and scale of a large corporation. He has spent most of his career helping founders build that bridge, drawing on his experience working both sides. At One Health Studio, he's excited to bring a diverse portfolio of companies to life and build the systems that help them reach their desired outcomes.

Outside of work, Mateus has traveled to more than 25 countries chasing new cultures, people, and food, and keeps a running list of where to go on his next adventure.
