Perfect Day's precision fermentation whey protein faced a $134M lawsuit from its contract manufacturer, exposing the fragility of outsourced bioprocessing

Perfect Day, the most prominent precision fermentation dairy company, was sued by Italian contract manufacturer Olon for $134 million in unpaid bills and alleged contractual breaches. While the lawsuit was eventually settled in January 2025 with each party covering its own costs, the dispute laid bare a fundamental vulnerability in the precision fermentation business model: most companies do not own their own production capacity. They rely on a small number of contract manufacturers (CMOs) who operate fermentation tanks originally built for pharmaceutical or industrial enzyme production. This matters because the relationship between a precision fermentation startup and its CMO is inherently fragile. The startup depends entirely on the CMO for production — if the CMO raises prices, delays batches, or sues, the startup has no product to sell. Perfect Day's situation was compounded by the fact that it had already laid off 15% of its workforce in 2023, shuttered its consumer-facing brand (The Urgent Company / Coolhaus), and seen its founders step down in 2025 as the company scrambled to close a ~$90 million pre-series E round. The company's new Gujarat, India production facility is not expected to begin operations until the second half of 2026, with ramp-up into 2027 — meaning Perfect Day has spent over a decade and hundreds of millions of dollars without controlling its own manufacturing at scale. The structural problem is that building dedicated fermentation facilities costs hundreds of millions of euros, and neither VCs nor banks will fund construction for technology that has not been commercially proven. So startups must use CMOs, but CMOs have limited capacity, limited expertise in food-grade (vs. pharma-grade) fermentation, and limited patience for startups that cannot pay on time. The gap between pilot-scale capability and industrial-scale supply continues to widen, and as the PPTI has noted, customers and investors increasingly favor suppliers that can deliver consistent volumes, predictable pricing, and robust logistics — exactly what the CMO model cannot guarantee.
