French AgTech Startup Tellia Raises €4.3M for Voice AI
Tellia, a Paris-based voice AI assistant for agriculture founded in 2024, has raised €4.3 million ($5 million) in a pre-Seed round to scale its voice-enabled data capture technology. The round was led by Revent, with participation from Grey Silo Ventures (CVC of Cereal Docks Group), Jeriko (operated by Techmind), and Fund F. Tellia's platform allows farmers, agronomists, and field teams to capture and use data by speaking, addressing the challenge of traditional software that requires manual data entry. The company plans to use the funding to advance its agentic AI layer, grow its team in the US and Europe, and accelerate the rollout of its suite, which partners can embed via a simple API. The raise is part of a broader trend of AI investment in European agriculture.
Funding round for a niche AgTech startup; relevant to AI in agriculture but not directly core AdTech/MarTech.
