Grey Silo Ventures Research
Investment Thesis
Grey Silo Ventures (GSV) is the corporate venture capital arm of Cereal Docks Group, an Italian agribusiness founded in 1983 that processes roughly 3 million tons of agricultural raw materials a year into oils, flours, lecithin, and functional ingredients. GSV was launched with the explicit ambition of evolving the Group's business "from commodity to ingredients" by backing science-driven startups that expand the portfolio of functional, non-animal-based ingredients. The firm frames itself as wanting to be an "ingredient of change" in the food and agri-food value chain, investing capital alongside the Group's industrial, operational, and commercial expertise rather than capital alone.
Sector Focus
GSV organizes its thesis around four pillars: (1) enabling ingredients and technologies for non-animal-based food, including alternative fats, functional proteins, textured improvers/scaffolds, and specialty fibres; (2) fermentation-based ingredients and technologies spanning traditional, biomass, and precision fermentation; (3) agritech solutions, including farming digital tools, ag robotics, and ag biotech; and (4) cellular agriculture, including cell-based meat, cell-based dairy, and plant molecular farming. In 2026 the firm has visibly leaned into agtech and ag robotics, publishing a dedicated position paper series and adding a voice-AI farm-data startup to the portfolio.
Stage Focus
GSV invests from early-stage/seed through Series A, and explicitly says it wants to build "lasting collaborations" with founders rather than one-off checks, implying willingness to follow on.
Check Size
Check size is not disclosed on the website. Observed recent rounds (Tellia's $5M pre-seed, Aardaia's €5M seed) suggest GSV writes checks appropriate to seed-stage syndicates alongside multiple co-investors, but exact minimum/maximum figures could not be confirmed and are omitted rather than guessed.
Lead Tendency
In its two most recently announced deals, GSV was a participant rather than the lead: Tellia's pre-seed was led by Revent (with Jeriko and Fund F also participating), and Aardaia's seed round was led by Point Nine (with Astanor and FoodLabs also participating). This suggests GSV typically operates as a syndicate participant rather than a lead investor, consistent with a strategic/corporate-VC mandate.
Recent Activity
GSV has been active through 2026: it invested in Tellia, a voice-AI farm data-capture startup (announced September 2026, part of a $5M pre-seed), and joined Aardaia's €5M seed round to develop new nitrogen-fixing crops (announced July 2026). Around the same time, GSV published "Position Paper #5: Ag Robotics — Exploring the Current Gap between Adoption and Innovation," featuring interviews with the CEOs/co-founders of AgXeed, Kilter, and Agtonomy. The firm also regularly publishes thesis essays on food-tech investing conditions, marking its fourth year of activity in 2026.
Portfolio Highlights
GSV's portfolio (including prior Cereal Docks Group investments folded into the venture arm) spans alternative proteins, fermentation, and agritech: Juicy Marbles (plant-based whole-cut steaks), Planetarians (upcycled plant protein, since wound down), X-Farm Technologies (precision-farming SaaS), Nosh.Bio (fungal fermentation proteins), Mushlabs (mycelium-based ingredients), Formo (precision-fermented, animal-free dairy proteins), MicroHarvest (microbial protein via fermentation), Foreverland (cocoa-free chocolate ingredients, which raised a €6M round in March 2026), Arsenale Bioyards (industrial biomanufacturing/precision fermentation, which raised ~€10M in February 2025), Revyve (yeast-derived texturizing proteins, which raised €24M), plus the newer additions Aardaia and Tellia.

Decision Process
Not disclosed publicly. Given the small core investment team (three people) backed by a scientific advisory board and venture partners, decisions likely flow through the Managing Partner with input from the broader Cereal Docks Group; this is inferred, not confirmed.
Founder Preferences
GSV states it invests "in people before technologies and companies," looking for teams driven by their founding story, inspired by curiosity and passion, empowered by diversity, and aware of the responsibility of being entrepreneurs.
Geographic Focus
GSV describes itself as having an "international focus." Its portfolio spans Italy (Foreverland, Arsenale Bioyards), Germany (Formo, Mushlabs, Nosh.Bio), the Netherlands (Revyve, Aardaia), the US (Planetarians), and Slovenia (Juicy Marbles), with recent deals also touching US/Europe-facing startups like Tellia.
