Finnish biotechnology firm Kääpä Biotech has closed a €9 million strategic investment led by PeakBridge and Zintinus to expand production capacity and strengthen its position in the global nutraceutical market
The funding will enable vertical integration expansion and scale operations to meet surging international demand from over 180 companies across 20+ markets
This marks PeakBridge's second investment in Kääpä following a €900,000 injection earlier in 2025, signalling sustained confidence in the company's bioactive-focused approach
Finnish biotechnology company Kääpä Biotech has secured €9 million in strategic funding to reinforce its position as a category leader in functional mushroom ingredients. The investment round, led by PeakBridge and Zintinus, represents a significant milestone for the European functional mushroom sector and underscores growing investor confidence in science-backed nutraceutical innovation.
Doubling Down on Vertical Integration
The funding will accelerate production capacity expansion, deepen vertical integration, and strengthen the company's NordRelease® ingredient platform. For PeakBridge, an agri-food technology fund manager within the Edmond de Rothschild Private Equity partnership, this represents a second investment in Kääpä following a €900,000 commitment earlier in 2025. Zintinus, a food technology venture capital fund focused on alternative proteins and functional nutrition, joins as a new strategic partner.
Eric Puro, Chief Executive Officer and Co-Founder of Kääpä Biotech, framed the investment within the context of rapidly expanding market demand. The functional mushroom sector continues to attract consumer interest driven by demand for high-quality, science-backed products. Kääpä now serves more than 180 companies across over 20 markets, positioning itself as a preferred partner in the wellness, nutrition, and supplement sectors.
Puro emphasised the strategic value of the partnership beyond capital. PeakBridge's tailored value-add programmes for portfolio companies, guided by a team with deep food industry expertise, align closely with Kääpä's growth objectives. The addition of Zintinus brings further strategic connections and sector-specific knowledge to support ongoing expansion.
Addressing Supply Chain Vulnerabilities
For investors, Kääpä's appeal lies in its vertically integrated model and focus on bioactive standardisation. Dr Gali Artzi, Partner and Chief Technology Officer at PeakBridge, highlighted the company's approach to addressing real supply chain vulnerabilities within the functional mushroom sector. The combination of rigorous bioactive standardisation and a European production base reduces dependence on Asia's concentrated production networks, which control over 90% of global supply.
Dr Artzi positioned functional mushrooms as more than a wellness trend, describing them as a convergence of centuries of traditional use, growing clinical evidence, and modern extraction science capable of delivering measurable health benefits. Kääpä's vertical integration from cultivation through extraction distinguishes it from competitors reliant on third-party suppliers.
Christian Neuss, Partner at Zintinus, described the investment as timely, coming at a pivotal moment for the functional mushroom industry. The sector is projected to experience rapid growth as global demand for science-backed functional foods and beverages continues to rise. Kääpä's proprietary NordRelease® extraction process, clinically validated ingredients, and scalable indoor cultivation infrastructure position the company to define the future direction of the market.
Neuss emphasised the alignment between Kääpä's commitment to transparent production and vertical integration with Zintinus' mission to support transformative food technologies. The partnership aims to accelerate growth whilst creating long-term value for consumers, the environment, and investors.
Expanding Production Infrastructure
The €9 million investment builds on recent operational milestones. In September 2024, Kääpä unveiled a state-of-the-art cultivation facility in Paimio, Finland, markedly expanding both production capacity and research and development capabilities. More recently, in June 2025, the company opened an additional cultivation facility in Salo, Finland, further strengthening its ability to meet growing global demand for Nordic-origin, premium functional mushroom ingredients.
These facilities utilise advanced climate control and automation technologies to create optimal growing conditions for fruiting body production. The controlled environment enables consistent output of high-quality mushrooms with verified bioactive compound content, addressing quality inconsistencies that have plagued the broader functional mushroom market.
The Science Behind the Strategy
Kääpä's approach centres on species-specific bioactive compounds rather than generic quality markers. Whilst many mushroom products are evaluated solely on beta-glucan content, Kääpä quantifies and standardises compounds such as Hericenones in Lion's Mane, Cordycepin in Cordyceps militaris, Ganoderic Acids in Reishi, and Inotodiol in Chaga. These compounds are linked to specific health benefits through clinical research, including cognitive function support, energy enhancement, stress resilience, and antioxidant activity.
The company's NordRelease® extraction technology, validated by the European Food Safety Authority in April 2025, enables efficient extraction of these bioactive compounds. Each product batch is accompanied by comprehensive Certificates of Analysis documenting species-specific compound concentrations, providing transparency and enabling accurate formulation by customers.
This focus on bioactive standardisation represents a fundamental shift in how functional mushroom quality is defined and measured. As the sector continues to professionalise, regulatory scrutiny and consumer education are increasing pressure on manufacturers to move beyond simplistic quality metrics.
Market Dynamics and Growth Trajectory
The functional mushroom market is projected to reach $65 billion globally by 2030. In the United States, sales of functional mushroom supplements increased by 75.8% in 2023 alone, representing the largest percentage gain of any ingredient in the mainstream retail channel that year, according to the American Botanical Council's HerbalGram report. This rapid growth reflects consumer demand for natural health solutions supported by both traditional use and emerging clinical evidence.
However, market expansion has brought quality challenges. Ingredient authentication, species verification, and bioactive compound quantification remain inconsistent across the industry. Products marketed as mushroom extracts may contain myceliated grain with minimal bioactive content, whilst labelling practices often lack clarity on ingredient composition.
Kääpä's vertically integrated model addresses these challenges through controlled cultivation, standardised extraction, and batch-specific testing. The company's European production base, EU organic certification, and transparent supply chain documentation differentiate it within a market dominated by Asian suppliers with variable quality standards.
Strategic Positioning and Future Outlook
The €9 million investment positions Kääpä to capitalise on structural shifts within the functional mushroom sector. As regulatory frameworks evolve and consumers become more discerning, companies with robust quality systems, transparent operations, and clinical validation are likely to gain market share.
Kääpä's expansion of production capacity, deepening of vertical integration, and strengthening of its bioactive-focused ingredient platform align with these market dynamics. The company's ability to serve a growing customer base across diverse international markets whilst maintaining stringent quality standards will be critical to sustaining growth.
For the broader functional mushroom industry, Kääpä's trajectory signals a maturation phase. The shift from generic quality markers to species-specific bioactive standardisation, from opaque supply chains to transparent traceability, and from commodity ingredients to validated functional compounds represents the evolution of a sector moving from niche wellness trend to evidence-based nutraceutical category.
The involvement of established investment firms such as PeakBridge and Zintinus further validates this trajectory, bringing not only capital but strategic expertise and industry networks that can accelerate commercialisation and market penetration.
