DateStageInvestorsRaisedDeal Summary
Sep 2025Undisclosed stageTrinity Capital (lead)$50MNalu Medical is a commercial-stage medical device company developing and commercializing neurostimulation solutions, specifically the Nalu Neurostimulation System, for patients with chronic intractable neuropathic pain. The system features a proprietary implantable pulse generator (IPG) that is battery-free, smartphone-controlled, and MRI-conditional, delivering gentle electrical pulses to modulate pain signals. On September 16, 2025, Trinity Capital Inc. (NASDAQ: TRIN), an alternative asset manager focused on private credit markets, committed up to $50 million in growth funding to support Nalu's continued commercial momentum, including expansion following recent FDA clearance for MRI use and publication of the largest long-term real-world data set for a permanent peripheral nerve stimulation (PNS) device demonstrating reliable pain relief. This non-dilutive growth capital from Trinity, structured across its life sciences vertical, provides financial flexibility for Nalu's commercial expansion of its next-generation Therapy Disc and broader market penetration in the chronic pain sector, positioning it as an alternative to opioids and competing with spinal cord stimulation (SCS) technologies. Trinity's Senior Managing Director of Life Sciences, Rob Lake, highlighted Nalu's leadership in PNS and its innovative technology backed by robust clinical data. Nalu's President and CEO, Tom West, welcomed the partnership to advance patient care. Previously, in late 2023 and early 2024, Nalu closed an $85 million Series E equity round led by Novo Holdings ($65M), with an additional $20M from new investor B Capital, and participation from existing investors including Gilde Healthcare, MVM Partners, Endeavour Vision, Decheng Capital, Longitude Capital, Advent Life Sciences, Pura Vida, and Aperture Venture Partners. Those equity proceeds were earmarked for accelerating commercial growth, expanding clinical and health-economic evidence, product development, and operations scaling.

The system features a revolutionary micro-implantable pulse generator (micro-IPG) cleared by the FDA for spinal cord stimulation (SCS) to treat specific types of lower back pain and peripheral nerve stimulation (PNS) for joint pain. It targets unmet needs in both emerging PNS and established SCS markets with strong clinical evidence of meaningful results. In January 2024, Nalu closed the first tranche of its Series E equity financing with $65 million led by new investor Novo Holdings. Existing significant investors participated, including Gilde Healthcare, MVM Partners (or MVM Life Science Partners), Endeavour Vision, Decheng Capital, Longitude Capital, Advent Life Sciences, Pura Vida Investments, and Aperture Venture Partners. Proceeds fund accelerated commercial growth, expanded clinical and health-economic evidence, product development, and operations scaling amid high revenue growth. Nalu has demonstrated commercial and clinical progress, with investors highlighting rapid growth potential and a growing body of clinical data from studies like the COMFORT-2 PNS randomized controlled trial initiated in June 2023. Management emphasizes building physician evidence for expanded patient access and payer coverage. In a later development, Boston Scientific, a strategic investor since 2017, agreed to acquire Nalu Medical. The deal includes an upfront cash payment of approximately $533 million for remaining equity (on a 100% basis before adjustments: $600 million), expected to close in the first half of 2026.

Post-market studies showed strong efficacy, with 86% of patients achieving at least 50% pain reduction in lower back and leg pain after three months, and 54% reporting 80% or more relief. Patient preference surveys indicated strong favor for Nalu's device over competitors due to its design. Nalu's micro-implantable pulse generator (micro-IPG) was highlighted in trials like COMFORT RCT for significant pain reduction and lower healthcare costs, including 61% reduction in outpatient costs. Projections from Boston Scientific's 2025 acquisition anticipated over $60 million revenue in 2025 with >25% YoY growth in 2026. A later Series E extension in late 2023 added $20M from B Capital, bringing total equity to $85M led by Novo Holdings. In October 2025, Boston Scientific agreed to acquire the remaining stake in Nalu Medical for $533 million cash, having been involved since 2017, to expand its chronic pain portfolio including spinal cord stimulation and ablation therapies. The deal was expected to close in H1 2026 and be immaterial to adjusted EPS in 2026, accretive thereafter.
