Sep 2020Series A-$9MMonteris Medical is a medical device company developing a robot-guided laser probe system (NeuroBlate System) for minimally invasive neurosurgery, including treatment of brain tumors and other brain tissue conditions. The technology was developed at St. Boniface General Hospital Research Centre and commercialization began in 1999. The company raised capital in 2020 through unattributed VC funding ($9M) and debt financing, though specific valuation and financial metrics for those rounds are not publicly available. The company has grown significantly, with approximately 105 employees (90 in the U.S., remainder in Canada) and raised approximately $207 million cumulatively across multiple rounds by 2022. By 2025, Monteris reported US$35 million in revenue and achieved near-term profitability, which positioned it for Series E financing. In March 2026, the company closed a $28 million Series E equity round led by existing investors InnovaHealth Partners and Birchview Capital, with participation from new investors including OSF Ventures and the Colorado University Healthcare Innovation Fund. The company also established a $35 million credit facility with Trinity Capital, with funds dedicated to expanding U.S. commercial operations, technology development, clinical research, and geographic expansion.

Nov 2014Series BThe Vertical Group; BDC Capital$30MMonteris Medical, a medical device company developing MRI-guided laser-based treatments for brain cancer, announced a Series B preferred equity financing round totaling slightly under $30 million in two tranches, with the first closing on November 6, 2014, and the second by March 31, 2015. The round was led by new investor Birchview Capital, with participation from new investor The Vertical Group and existing investor BDC Capital Healthcare Fund. Warrants issued to investors could generate an additional $10.6 million if exercised. As part of the deal, Matthew Strobeck from Birchview Capital and Richard Emmitt from The Vertical Group joined the board. The funding supports expansion of commercial and clinical programs for the NeuroBlate robotic neurosurgical system, a minimally invasive FDA-cleared device for treating brain tumors using MRI-guided laser ablation. At the time, Monteris had a customer base of approximately 25 leading neurosurgery centers and aimed to accelerate adoption. The company, formed in 1999 and based in Plymouth, Minnesota (with prior Winnipeg roots), markets the NeuroBlate System alongside products like the AXiiiS Stereotactic Miniframe and AtamA Head Coil. A later Series C round of $26.6 million was led by SightLine Partners and Versant Ventures with BDC and Birchview participation, funding further NeuroBlate commercialization after over 1,200 procedures since 2013 FDA approval.
Apr 2014Seed-$3MMonteris Medical develops minimally invasive laser systems for ablating pathologic brain lesions such as primary and metastatic tumors using the NeuroBlate robotic neurosurgical system. The NeuroBlate device, FDA-cleared in April 2013 and approved by Health Canada, employs MRI-guided laser energy via a gas-cooled fiber-optic probe to treat brain tumors and lesions. In April 2014, Monteris raised $13 million in financing, including $8.3 million in equity from BDC Venture Capital, SWMF Life Science Fund, and others, plus $5 million in debt from Oxford Finance, to support North American commercialization of NeuroBlate. On November 13, 2014, Monteris announced a $30 million Series B preferred equity financing in two tranches, led by Birchview Capital with participation from The Vertical Group and BDC Capital Healthcare Fund, including warrants potentially worth $10.6 million if exercised. The funds aimed to expand commercial and clinical programs for NeuroBlate, which had a growing sales pipeline and increasing surgeon utilization at the time. Later rounds included a $26.6 million Series C in 2017 led by SightLine Partners and Versant Ventures, bringing total funding over 18 years to more than $120 million, with NeuroBlate used in over 1,200 procedures across dozens of U.S. and Canadian hospitals.

Jan 2013Series ABusiness Development Bank of Canada (lead)$8MMonteris Medical, a medical device company developing MRI-guided laser-based treatments for brain cancer, announced a $7.8 million financing round led by Business Development Bank of Canada (BDC), with participation from SWMF Life Science Fund and other investors. The funds supported commercialization efforts for the NeuroBlate System, an FDA-cleared neurosurgical ablation device for treating brain tumors. BDC expressed confidence in Monteris' technology, management team, regulatory clearances, and hospital reimbursement. This round aligns with Monteris' activities around mid-2013, following FDA clearance for NeuroBlate in April 2013. Subsequent financings included a $13 million raise with $8.3 million in equity from BDC Venture Capital and others, plus $5 million debt, pushing two-year capital over $30 million to fund North American rollout and postmarket trials.
