Infinite Roots acquires Bosque Foods as mycelium sector consolidates around industrial scale-up

Infinite Roots has acquired fellow mycelium startup Bosque Foods in a deal that highlighted the growing consolidation underway across the fermentation and alternative protein sectors, as companies with industrial infrastructure and scale-up capabilities emerged in a stronger position than smaller research-focused players.

The acquisition was announced by Bosque Foods Founder & CEO Isabella Iglesias-Musachio, who described the move as the next chapter for the company’s technology after nearly six years building the business across the US and Europe.

• Infinite Roots acquired Bosque Foods following nearly six years of mycelium technology development by the startup across the US and Europe.
• Bosque founder Isabella Iglesias-Musachio said the mycelium sector was consolidating around companies with infrastructure and industrial execution capabilities.
• Infinite Roots said the acquisition added expertise in solid-state fermentation and whole-cut product development to its existing mycelium platform.

“After nearly six years of building Bosque Foods, I'm excited to share that we've completed a strategic acquisition by Infinite Roots,” Iglesias-Musachio wrote in a LinkedIn post announcing the transaction.

While financial details of the deal were not disclosed, the acquisition reflected a broader shift taking place across alternative proteins, where investor focus increasingly moved from early-stage scientific novelty toward manufacturing readiness, industrial partnerships, and scalable infrastructure.

Bosque Foods had emerged from the IndieBio accelerator ecosystem and grew into a 25-person team spanning scientists and engineers across the US and Europe. During that period, the company developed technologies centered on mycelium cultivation and biomass fermentation.

“We developed breakthrough technology in mycelium cultivation and biomass fermentation, and pushed the boundaries of what's possible in sustainable food,” Iglesias-Musachio wrote.

The announcement also offered an unusually candid reflection on the pressures facing climate-tech and alternative protein startups over the last several years, as venture funding slowed sharply across the sector following the rapid growth period of 2020-2022.

“The climate tech sector faced real headwinds over the past few years, and navigating that required resilience from everyone involved,” Iglesias-Musachio said. “Through it all, I was surrounded by people who believed in what we were building.”

Rather than presenting the acquisition as simply a corporate transaction, Iglesias-Musachio positioned it as part of a wider maturation process taking place within the mycelium category itself.

“Infinite Roots offered the right home for Bosque's technology to continue developing at scale,” she wrote. “As the mycelium category matures and consolidates around companies with the infrastructure to industrialize, their platform gives what we built a strong path forward - and that's exactly the outcome I hoped for.”

That statement captured a dynamic increasingly shaping the fermentation industry in 2026. Over the past two years, many companies focused on novel proteins, biomass fermentation, and precision fermentation have struggled with the realities of industrial manufacturing costs, infrastructure requirements, and commercial deployment timelines.

While the science underpinning many of those businesses continued advancing, the capital intensity associated with scaling food production remained one of the sector’s defining challenges.

Infinite Roots appeared to have spent much of the last several years preparing specifically for that transition from research to industrial execution.

Formerly known as Mushlabs, the Hamburg-based company closed a €53 million (US$60.7 million) Series B round in January 2024, which at the time represented one of Europe’s largest investments in mycelium technology. The oversubscribed funding round included backing from Dr Hans Riegel Holding, the investment arm linked to Haribo, alongside participation from the EIC Fund, REWE Group, Betagro Ventures, and existing investors including FoodLabs, Redalpine, Simon Capital, and Happiness Capital.

At the time, Infinite Roots said the financing would support expansion of production capacity and global commercialization efforts for its mycelium-based food platform.

The company also spent 2024 building partnerships tied directly to industrial applications and large-scale food production.

In March 2024, Infinite Roots announced a collaboration with South Korean food manufacturer Pulmuone to develop mycelium-based protein products tailored to local consumer preferences in South Korea. The partnership combined Infinite Roots’ fermentation technology with Pulmuone’s product development and retail expertise.

“Working with Pulmuone is a true honor for us,” Infinite Roots Founder & CEO Dr Mazen Rizk said at the time. “We are very happy to join forces with a partner with such market power and an equally visionary mindset.”

Later that year, Infinite Roots secured €2.6 million (US$3 million) in funding for a whey valorization project developed alongside Hamburg University of Technology. The initiative focused on using dairy byproducts as nutrient streams for mycelium fermentation, creating an upcycling pathway for industrial food waste.

The company described the technology as a way to transform whey, which is often costly and environmentally problematic to dispose of, into a resource for fermentation-based protein production.

Taken together, those developments painted a picture of a company increasingly focused not only on ingredient development but also on industrial integration, supply chain efficiency, and scalable manufacturing systems.

That industrial emphasis appeared central to the Bosque acquisition.

Infinite Roots Founder & CEO Dr Mazen Rizk described the acquisition as an expansion of the company’s technical capabilities and long-term ambitions for the mycelium category. “When I started Infinite Roots in 2018, I made a bet: The mushroom kingdom would become a staple ingredient in kitchens and supply chains worldwide,” Rizk wrote in a LinkedIn post. “Today, we're doubling down.”

Rizk said the acquisition added “deep expertise in solid-state fermentation and whole-cuts” to Infinite Roots’ broader biotechnology and mycelium platform.

“More IP. More Process Data. More Firepower to lead the market,” he wrote.

He also framed the deal as part of a broader effort to unlock new industrial applications for fungi-based technologies.

“With the right technological building blocks, we are unlocking the full potential of this beautiful kingdom to create innovative and sustainable solutions for pressing problems we are faced with globally,” Rizk said.

While Bosque Foods had developed its own fermentation and mycelium expertise, Iglesias-Musachio acknowledged that long-term success in the sector would likely depend on companies capable of combining biological innovation with manufacturing depth.

“The future of mycelium will be shaped by companies that can combine biology, process understanding, and industrial execution,” she wrote. “And I'm glad our work will be part of that next chapter.”

The deal also reflected a broader consolidation trend underway across food-tech and climate-tech more widely, where smaller startups increasingly sought strategic acquisitions or integrations with better-capitalized operators rather than attempting to independently scale manufacturing infrastructure.

Over the past 18 months, multiple fermentation and alternative protein companies across Europe and North America have either reduced operations, shifted strategic focus, pursued mergers, or sought acquisition pathways as fundraising conditions tightened.

For many companies, the issue was not necessarily scientific viability, but the enormous financial and operational complexity involved in reaching commercial food manufacturing scale.

Building dedicated fermentation infrastructure remained one of the most expensive barriers in the sector, particularly for startups operating in biomass fermentation, precision fermentation, or cultivated proteins.

Against that backdrop, companies with existing industrial networks, manufacturing partnerships, and established commercialization pathways increasingly occupied stronger positions.

Bosque’s acquisition by Infinite Roots therefore represented more than a transfer of intellectual property. It illustrated how the sector itself was evolving from an ecosystem dominated by early-stage innovation toward one increasingly shaped by operational execution.

Iglesias-Musachio also emphasized that preserving the underlying work of Bosque’s team had been an important outcome.

“I'm genuinely proud that the IP, know-how, and years of R&D our team poured into Bosque will continue to grow,” she wrote.

The announcement drew attention from across the climate-tech and alternative protein sectors, particularly because Bosque had become well known within the mycelium ecosystem through its work on biomass fermentation and fungal cultivation technologies.

Iglesias-Musachio thanked Bosque’s scientific team, investors, advisors, and early backers, including FoodLabs, SOSV, IndieBio, ProVeg Incubator, Sprout & About Ventures, Happiness Capital, Blue Horizon, Blue Impact, and Arman Anatürk.

The acquisition also reinforced the increasingly important role being played by specialist fermentation and mycelium companies within the broader alternative protein landscape.

While plant-based meat companies dominated headlines earlier in the decade, mycelium-based products gained traction because of their relatively efficient production methods, natural texture characteristics, and nutritional profile. Several companies in the category focused heavily on biomass fermentation as a route toward lower-cost protein production without the extreme infrastructure demands associated with cultivated meat.

At the same time, however, industrialization remained a major dividing line.

The challenge was no longer simply proving mycelium could work as a food ingredient. The question increasingly facing the sector was which companies could actually manufacture it economically at large scale.

Bosque’s integration into Infinite Roots suggested that, for some startups, the next phase of growth may come less through independent expansion and more through consolidation into platforms already equipped for industrial deployment.

For Infinite Roots, the acquisition strengthened both its technical capabilities and its position within a rapidly narrowing group of fermentation companies still actively scaling toward large-scale commercial production.
