PHACTORY is a unique pan-European consortium operating as a one-stop-shop virtual factory for photonics innovation support of European industry. PHACTORY brings together over 30 partners representing Europes top competence centers in photonics. Together the PHACTORY partners offer open streamlined access to the full spectrum of photonics technologies, expertise and supply chain activities from TRL2-7 including pilot lines and PIC foundries, combined with specialist partners in business, investment, intellectual property, and EU manufacturing support services to maximize the commercial impact from the project. PHACTORYs ambitious work plan builds on the proven track record of over 20 years of successful collaboration between the consortium partners in previous similar EU projects and aims to go well beyond the current state-of-the-art in terms of its impact. PHACTORY will reach out broadly to European industry, especially SMEs, start-ups, and scaling companies, predominantly as first users and early adopters, to generate a critical mass of 125 carefully selected support cases with the highest potential for commercial impact. PHACTORY will work closely with the selected support cases, providing deep technology support interventions for TRL acceleration through intensive cross-border collaborative innovation projects, combined with tailored business supports to accelerate the investment readiness levels (IRL) of the supported companies. As a result, PHACTORY expects to achieve a quantified impact of at least 1250 new EU jobs, 937M in new company revenues, and 190M in new venture capital on aggregate within the supported companies directly related to the delivered PHACTORY innovation supports. The PHACTORY project will simultaneously strengthen the European photonics innovation ecosystem with more complete and mature value chains linked to EU manufacturing which are integrated into the PhotonHub Association for sustainability of the innovation support services.
