Background
Erwin Holtland is an Investment Manager at PhotonDelta, where he is listed on the team page and named as a funding contact for the PhotonDelta Startup Fund. PhotonDelta is a non-profit organization supporting the Dutch and European integrated-photonics value chain, from design and production to packaging and applications. Its startup fund launched in 2024 as a €60 million fund intended for deployment over five years.
Holtland also works in the Twente innovation ecosystem. MedTech Twente lists him as Business Community Manager, and Kennispark Twente lists him with the same role, reachable at a MedTech Twente email address and Dutch mobile number. His work there is tied to the MedTech Twente cluster, which connects companies, researchers, clinicians, startups, and scale-ups around medical-technology innovation.
Before PhotonDelta, Holtland held investment and business-development roles in the eastern Netherlands. The Org lists previous roles including Senior Investment Manager at Oost NL, Business Developer for Quantum at Hogeschool Saxion, Project Manager at MedTech Factory, Fund Manager for Regio Twente’s innovative SME loan fund, and Portfolio Manager at University of Twente Holding. MarketScreener records him as Senior Investment Manager at Ontwikkelingsmaatschappij Oost Nederland NV from 2019 to 2020 and Manager Participations at Holding Technopolis Twente BV from 2016 to 2019.

Investment Thesis & Focus
- PhotonDelta’s stated fund purpose is to provide financing in the early phase where startup risk is still high, using favorable, low-interest loans to help startups accelerate funding needs and reduce risk for co-investing venture capital funds.
- The fund targets photonic chip technology or direct applications of integrated photonics, with a practical link to wafer-production demand in the Dutch ecosystem.
- PhotonDelta’s stated eligibility criteria include companies under 5 years old, TRL 3-7, no commercial sales at scale, commercial activity in the Netherlands, and a promising business case with plan, budget, and cash-flow forecast.
- Loan terms disclosed by PhotonDelta include a 5-year linear loan, €250,000 to €2 million size range, 12-month Euribor interest rate, 18-month grace period, and pledges such as intellectual property or machinery.
- Use of proceeds can include technology and application development, market validation, business development, bringing innovation to market, pilot production capacity, and CAPEX for pre-production, prototypes, demonstrators, or shared-facility use.
- Holtland’s own quoted view on the Aluvia investment was that Aluvia’s technology has “strong potential across our portfolio” and that the partnership acts as “both a multiplier and an accelerator” for PhotonDelta companies.
