What HAPPE Spine does
HAPPE Spine, LLC is a Grand Rapids, Michigan-based medical device company founded in 2018 to commercialize a proprietary biomaterial platform for spinal fusion implants. The company's core technology, HAPPE (HydroxyApatite Porous PolyEtheretherketone), transforms conventional PEEK from a hydrophobic, bioinert polymer into a hydrophilic, bioactive, and osteointegrating material by embedding rod-like hydroxyapatite whiskers that remain exposed on all implant surfaces—including machined and internal pore surfaces. The platform uses a patented dual-density architecture in which monolithic implants are molded from powder-based raw materials, producing seamless porous regions (approximately 75% interconnected cancellous porosity with 200-500 micron pores) integrated with dense load-bearing regions, with no joints or bonds. HAPPE holds 11 issued US patents covering compositions, manufacturing processes, and implant designs, and is the exclusive orthopaedic device on the market using rod-like HA whiskers rather than spherical HA particles.
The company's commercial product is the INTEGRATE-C Interbody Fusion System, a cervical interbody spinal fusion cage that received FDA 510(k) clearance (K222004) in May 2023 and was first implanted clinically in August 2023. By November 2025, INTEGRATE-C had been used in over 1,000 patients across 30+ surgeon users and 40+ US facilities, generating over $2 million in 2025 sales. Surgeon testimonials cite earlier fusion and higher fusion rates versus 3D-printed titanium cages (especially in multilevel cases), no metal-artifact imaging interference, and bone-like mechanical properties that reduce stress shielding. The product is positioned as the first interbody cage to combine radiolucency, designed porosity, bioactivity, and bone-like modulus in a single device.
HAPPE operates a sales-led, enterprise-focused go-to-market targeting spine surgeons and hospitals, beginning with a strategic limited user release seeded at key opinion leader accounts and now transitioning toward broader distributor-based US expansion. Revenue is generated through hardware sales of spinal implants on quote-based, contract-negotiated pricing typical of the spine industry. The company is venture-backed, with $3.35 million raised in a November 2021 Series A led by strategic spine investors and the cultivate(MD) Seed II Fund, plus an oversubscribed bridge round completed in 2025 to support manufacturing scale-up and continued clinical validation. The technology was invented at the University of Notre Dame by Dr. Ryan K. Roeder, who serves as Founder, CTO, and Interim CEO; the board includes spine-industry veterans such as Andrew Iott (co-founder of Globus Medical) and Steven M. Foster (CEO of Tenon Medical).

HAPPE Spine product offering
Product offeringCore offering
HAPPE Spine designs, manufactures, and sells the INTEGRATE-C Interbody Fusion System, a cervical interbody spinal fusion cage made from its proprietary HAPPE (HydroxyApatite Porous PolyEtheretherketone) biomaterial. The product is sold to hospitals and spine surgeons in the United States and features fully interconnected cancellous porosity with hydroxyapatite exposed on all surfaces for osteointegration. The company also licenses/continues to develop its broader HAPPE biomaterial platform for future orthopedic implant applications.
Product overview
HAPPE Spine offers a proprietary biomaterial platform called HAPPE® (HydroxyApatite Porous PolyEtheretherketone) that enables bone-integrating orthopedic implants. The primary commercial product is the INTEGRATE®-C Interbody Fusion System, a cervical interbody spinal fusion cage. The HAPPE platform combines hydroxyapatite whiskers embedded in PEEK with fully interconnected cancellous porosity throughout the implant, creating implants that mimic bone structure and actively promote bone integration. The technology addresses limitations of conventional PEEK and titanium implants by providing both bioactivity for bone ongrowth and porosity for bone ingrowth, combined with radiolucency for superior imaging.

HAPPE Spine partnerships and signals
Strategic signalPartnerships
Three partnerships are on record, tiered strategic, minor and core.
- HimedstrategicHimed, an industry leader in hydroxyapatite (HA) biomaterials for 30 years, released a white paper highlighting the benefits of rod-like HA particles in PEEK. They are a materials supplier for the HA whiskers used in HAPPE technology and co-authored scientific publications validating the technology.
- Vertera (acquired by NuVasive)minorWhile Vertera developed surface-porous PEEK technology (now owned by NuVasive), their work validated the market direction toward porous PEEK. The competitive landscape they created helped establish the market readiness for HAPPE's fully porous and bioactive PEEK technology.
- University of Notre DamecoreThe HAPPE material platform was originally invented at the University of Notre Dame under Dr. Ryan K. Roeder. The company originated from research conducted at the university, and Dr. Roeder remains as Professor at Notre Dame and CTO/founder of HAPPE Spine. The partnership continues through ongoing research collaboration.
