Octopus Ventures

Octopus Ventures is the venture capital Arm of Octopus Group, a London-based financial services group also known for its Octopus Energy business. It is one of the most active early-stage investors in Europe, with a portfolio spanning health technology, fintech, deep tech, and consumer internet. Octopus Ventures typically invests from seed through to Series B and has backed over 160 companies including Elvie, Zoopla, and Butternut Box. Its health-tech practice has developed particular depth in digital health, diagnostics, and software-enabled care pathways.

Octopus Ventures co-invested in Semble's £30m Series C, alongside lead investor Revaia. Semble is a UK health-tech company focused on GP software and clinical workflow tools. The investment fits Octopus Ventures' established health-tech portfolio and its focus on technology that improves NHS-adjacent service delivery. Octopus' follow-on participation at Series C signals continued conviction in Semble's growth trajectory after earlier-stage support.

Octopus Ventures operates a specialist health-tech investment practice that has been building for over a decade, and its participation in Semble's round at this stage illustrates The Firm's capacity to support companies from early investment all the way through to meaningful scale. Its affiliation with Octopus Group, which also includes Octopus Energy (one of the UK's largest energy suppliers), provides portfolio companies with potential commercial linkages across the group's customer and partner network.
