BIO
Co-founder and CEO of Solidroad (W25). Before Solidroad, I founded Gradguide, a coaching and mentorship network for recent grads, where I raised €2M, grew the team to 20, and exited in late 2022. Earlier in my career, I led Sales, Support, and Customer Success for EMEA at Chargify (now Maxio) and worked as an early sales rep at Intercom. I studied Business at Trinity College Dublin and spent a year at HEC Paris.
