Companion Spine

What Companion Spine does

Companion Spine is a privately held French-American medical technology company specializing in motion-preserving spinal implants for the interventional treatment of degenerative disc disease (DDD), lumbar spinal stenosis, and related chronic back conditions. Founded in 2019, the company is headquartered in Mérignac, France with US operations based in New York, NY, and Leesburg, VA. Its stated mission is to provide reversible, minimally invasive alternatives to traditional spinal fusion surgery, spanning the full continuum of spine care from diagnostics through surgical intervention. The company employs 11-50 people and has raised approximately $60-65 million in Series A funding.

The company's product portfolio comprises four core devices built around posterior dynamic stabilization technology: the DIAM™ Spinal Stabilization System (FDA Premarket Approved in December 2025 for DDD, with over 200,000 implants performed across 76 countries), the LISA™ Posterior Dynamic Stabilization System (CE-certified under EU MDR, a third-generation device based on 35 years of clinical research, not currently available in the US), the coflex® Interlaminar Stabilization Device (FDA PMA-approved for one- or two-level lumbar stenosis at L1-L5), and the CoFix™ Implant (FDA 510(k)-cleared titanium posterior fixation adjunct for lumbar fusion support). Three of the four products were added through acquisitions—BACKBONE SAS in January 2023 (LISA) and Paradigm Spine GmbH from Xtant Medical Holdings in December 2025 for approximately $21.4 million (coflex and CoFix)—reflecting a programmatic M&A-driven portfolio assembly strategy.

Companion Spine generates revenue through direct hardware sales of spinal implants to hospitals, ambulatory surgery centers (ASCs), spine surgeons, and pain management physicians, supplemented by an international distributor network across Europe and Asia. Its go-to-market combines enterprise field sales with physician seminars, clinical training programs, surgeon case observations, and presence at major spine conferences including Eurospine and ISASS. Pricing is not publicly disclosed and follows typical med-device quote-based contracting that varies by procedure, facility, and contract terms.

Products and services

• DIAM Spinal Stabilization System FDA PMA-approved dynamic spinal stabilization device for treating degenerative disc disease and low back pain. Placed between vertebrae to share load borne by the disc and maintain vertebral height while preserving spinal motion. Targeted at spine surgeons and pain management physicians treating degenerative disc disease in hospitals and ambulatory surgery centers.
• coflex Interlaminar Stabilization System FDA PMA-approved titanium interlaminar stabilization device for lumbar spinal stenosis. Combines stability with natural motion preservation; implanted midline between adjacent lamina of 1 or 2 contiguous lumbar motion segments (L1-L5) after decompression in skeletally mature patients. For spine surgeons treating moderate to severe lumbar stenosis.
• CoFix Implant FDA 510(k)-cleared titanium posterior non-pedicle supplemental fixation device for lumbar fusion support. Wing and screw design provides secure fixation to adjacent spinous processes as an adjunct to interbody cage fusion at a single level (L1-S1). For spine surgeons performing lumbar fusion in patients with degenerative disc disease.
• LISA Posterior Dynamic Stabilization System CE-certified under EU MDR dynamic stabilization device for treating degenerative disc disease and low back pain at L1-L5 levels. A third-generation device invented in 1986 based on 35 years of clinical research, providing stiffness augmentation while preserving motion and anatomy in a fully reversible, minimally invasive procedure. For spine surgeons and pain management physicians in Europe and Asia (not yet available in the US).

Direct peers

• Centinel Spine: Spine device company specializing in motion-preserving total disc replacement (prodisc) — the most direct non-fusion peer to Companion Spine's posterior dynamic stabilization portfolio, and previously founded by CEO Anthony Viscogliosi.
• Orthofix Medical: Public spine and orthopedics company offering motion-preservation and fusion implants with a US sales force focused on surgeons and ASCs — directly comparable customer base and product overlap with Companion Spine.
• Alphatec Holdings: Spine-only public company focused on lateral and minimally invasive fusion and motion-preservation technologies, with a US surgeon sales force comparable in scale to Companion Spine's growth-stage commercial operations.

Broad incumbents

• ZimVie (Zimmer Biomet Spine): Spun off spine business of Zimmer Biomet offering motion-preservation and fusion products including the Mobi-C cervical disc — broad incumbent with overlapping posterior stabilization and cervical motion-preservation products.
• Stryker Spine: Large incumbent spine franchise (post-K2M acquisition) offering cervical and lumbar motion-preservation devices including the MESA and Tritanium systems — broad portfolio with overlapping degenerative disc and stenosis indications.
• Medtronic Spine: Largest spine medtech incumbent offering Prestige LP and Bryan cervical discs plus comprehensive lumbar portfolio — the dominant competitive benchmark for any spine motion-preservation entrant.
• Globus Medical: Major spine incumbent formed via NuVasive merger, with broad motion-preservation and enabling-technology portfolio — competitor across Companion Spine's lumbar stenosis and degenerative disc indications.

Emerging players

• Xtant Medical Holdings: Spine-focused company that divested coflex, CoFix, and Paradigm Spine assets to Companion Spine for ~$21.4M — comparable in scale and adjacent in product portfolio, representing the most recent seller-side peer.
• Premia Spine: Emerging spine company developing the TOPS posterior motion-preservation system — closely analogous motion-preserving lumbar technology targeting the same degenerative disc disease and stenosis indications as DIAM and coflex.
• Spineart: Privately held spine company offering motion-preservation and fusion implants across Europe and the US — comparable French/Swiss-origin mid-market spine competitor to Companion Spine's European franchise.
