Its legal entity is SIREN425113321, registered November2,1999; the operating brand reports research history since1985. It supplies biopharmaceutical companies, academic institutions and nonprofits with in-vitro, ex-vivo and in-vivo drug-discovery, efficacy, pharmacokinetic, safety-pharmacology, histology and toxicology services. Its central-nervous-system research covers epilepsy, cognition and aging, neurodegeneration, psychiatric disorders, stroke, pain and dependence liability, including electrophysiology and EEG. Its glioblastoma partnership with GlioCure and CHU Angers develops patient-derived preclinical models; these are research services rather than approved medicines or demonstrated clinical efficacy. The company publicly describes GLP-compliant and AAALAC-accredited operations. Xavier Morge became President in2025, while former President and CEO Guillaume Froget became Senior Advisor. The publicly named scientific, sales and marketing team is recorded separately from external research collaborators and historical employees. Paris Apax Partners SAS, renamed Seven2 in2023, announced a majority acquisition February21,2023 with existing management and shareholders reinvesting; this is ownership, not an inferred new-cash fundraising round. Its purchase price and issuer-primary-cash allocation remain unpublished. Porsolt acquired the Bordeaux cell-assay business Fluofarma in2015.

 Portabiles HealthCare Technologies | Portabiles HealthCare Technologies GmbH is an Erlangen, Germany digital-health company developing sensor-based gait analysis and hybrid care for people with Parkinson’s disease. It emerged in late2016 from research with University Hospital Erlangen and Friedrich-Alexander University Erlangen-Nuremberg’s machine-learning and data-analytics laboratory. Its ParkinsonGo service combines wearable sensors, a smartphone app, personalized movement exercises and support from qualified nurses and neurologists; its Mobile GaitLab and Stepmetric products support gait measurement in clinical and related settings. Algorithms analyze movement and patient-reported information to support clinical decision making and ongoing monitoring. These are care-support tools rather than a claimed cure or replacement for professional treatment. The exact operating entity is registered at Fürth under HRB17289, VATDE310040104, represented by founder and CEO Ralph Steidl at Henkestraße91,91052Erlangen. It is legally distinct from Portabiles GmbH, HRB14816/VATDE297736960, which operates portabiles.de at the same address with different managing directors; their funding and staff are not merged. Current own German directory identifies four management/advisory people and two external University Hospital Erlangen care partners; an older English directory remains live with additional staff whose current appointment status is qualified. EIT Health describes ParkinsonGo as a ClassI CE-marked device under MDR, and the company reports FDA registration with 510(k) exemption. This is not a claim of FDA clearance or approval. Product research, reimbursement arrangements and intended international projects are distinguished from proven outcomes and regulatory authorizations. EIT Health has supported the company through its2020 Start-up Rescue Instrument, later financing and digital-health innovation programs; staged fundraises and total-round disclosures are qualified separately to avoid adding cumulative or approximate amounts as fresh cash. | |
