  • Wellumio, a New Zealand medtech startup, has raised $9.75 million in an oversubscribed pre-Series A funding round.

The new funding will help Wellumio grow its team, strengthen its technology, and speed up its clinical trials, regulatory approvals, and commercial launch.

Dr Shieak Tzeng, Co-founder and CEO of Wellumio, says investor support from New Zealand, Australia and the United States demonstrates growing international confidence in Wellumio`s mission to improve stroke diagnosis and recovery through its portable neuroimaging technology.

“Every minute counts in stroke care, yet only a small proportion of patients receive treatment within the golden hour, when timely intervention offers the best chance of reducing long-term disability. Our portable, AI-enhanced MRI-based brain imaging technology is designed to rapidly detect acute stroke at the point of care, helping clinicians make faster treatment decisions when time matters most".

“The additional investment, combined with the expertise and international networks our investors bring, will help accelerate our clinical validation, regulatory and commercial milestones as we work to bring our technology closer to healthcare providers and patients who need it most.”

Jeff Reid, General Partner of Bioshore Ventures, said, “Bioshore Ventures is delighted to participate in Wellumio’s pre-Series A round. As a dedicated medtech fund focused on game-changing technologies developed in our region, we have been extremely impressed by what the Wellumio team has achieved.

“There is a significant global opportunity to improve stroke care, with timely diagnosis being a critical element of the care continuum. We believe Axana is at the forefront of a major shift toward faster, point-of- care stroke diagnosis, and we look forward to working with the Wellumio team to bring this technology to healthcare systems around the world.”
