Polish startup Proteine Resources raises €9.5 million to build autonomous insect protein factory and launch beef alternative for pets
Masłomiąca-based Proteine Resources, a BioTech startup developing next-generation functional proteins from insects, has secured €9.5 million in blended financing from the European Innovation Council (EIC) Accelerator.
Selected from thousands of applicants, Proteine is one of two Polish startups in this cohort, and just the 9th ever from Poland to receive the grant. Proteine is supported by SMOK Ventures, Bitspiration Booster VC, and has participated in EIT Food Accelerator Network (EIT FAN), including the Circular Economy Hub in Helsinki and Labena Ventures Accelerator.
“The EIC Accelerator is where DeepTech gets its wings,” said Bartłomiej Roszkowski, Co-founder and Co-CEO of Proteine – and a YC alumnus. “We’re thrilled to be among the few selected. It’s a powerful validation of what we’ve built – and what’s coming next.”
Founded in 2017, Proteine’s mission is to create functional, high-performance proteins tailored to the needs of animals – with a focus on health, digestibility, and sustainability. Its proprietary insect bioconversion platform upcycles mushroom stems and mycelium, reportedly converting them into premium-grade protein rich in bioavailable taurine and L-arginine.
These are critical amino acids for cats and active pets, supporting:
- Immune balance
- Digestive health
- Allergy mitigation
- Visible coat and skin improvements.
“We’re not just producing protein – we’re delivering a performance ingredient,” said Konrad Wlodarczyk, Founder of Proteine Resources and technology developer. “It works because it’s built with biology in mind – from the input stream to the metabolic profile.”
According to the company, the product has also shown exceptional palatability, including for sensitive animals like cats, which are often challenging to serve with novel proteins.
The €9.5 million in funding will allow Proteine to build a 10x scaled pilot facility, launch the world’s first fully autonomous insect protein factory, deploy a modular, low-energy design adaptable to any location with sidestream feedstock and commercialise a 1:1 functional analogue of beef for the premium pet food segment.
By integrating AI-based controls and automation, Proteine aims to reduce operational costs and enable decentralised production — innovating how sustainable proteins can scale.
In many European countries, mushroom growers spend up to €80k per year disposing of residual stems and mycelium – a cost Proteine’s solution transforms into a revenue-generating input – as per comments by Proteine.
Their system allegedly:
- Eliminates waste management costs
- Reduces greenhouse gas emissions and leach risk
- Provides local farmers with a stake in circular food innovation.
“We help turn a problem into a profit center,” said Roszkowski. “And we do it in a way that’s scalable, measurable, and emissions-neutral.”
Its ingredients are bioactive, digestible, climate-positive and cost-effective.
“What Proteine has built isn’t just a product – it’s a platform,” said Borys Musielak, managing partner at SMOK Ventures. “They are transforming one of the biggest environmental challenges in agriculture into a scalable business with real BioTech credentials. That’s rare.”
“BioTech that’s both sustainable and commercially aggressive is hard to come by,” added Andrzej Targosz, partner at Bitspiration Booster VC. “Proteine’s model hits all the right notes – circular, autonomous, and globally relevant. We’re excited to be part of the journey.”
