Strella Biotechnology Raises $4.3M Series A Led by Silver Blue LLC

Strella Biotechnology, a developer of IoT ethylene-gas biosensors for the produce supply chain, has raised a $4.3 million Series A round led by Silver Blue LLC. PeakBridge, LeVert Ventures, and Beta Milouot also participated in the round.

What Strella Does

Strella Biotechnology builds IoT ethylene-gas biosensors that provide real-time ripeness and quality data on fruit as it moves through storage, distribution, and retail. Ethylene is a key driver of ripening and spoilage, and continuous monitoring gives growers, packers, and retailers visibility into produce condition throughout the supply chain.

The company's stated goal is to help these customers cut food waste. Its sensors currently monitor produce across more than 26 countries.

Company Background

Strella Biotechnology was founded in 2018 by Katherine Sizov. Prior to this round, the company had raised over $11 million from investors including Millennium New Horizons, Google Ventures, and Yamaha Motor Ventures.

That prior investor base spans venture capital, corporate venture, and strategic industrial interests — a mix that reflects the company's position at the intersection of agriculture, logistics, and sensor hardware.

Round Details

• Company: Strella Biotechnology
• Round: Series A
• Amount: $4,300,000 USD
• Date: October 23, 2026

Why It Matters

Food waste in the produce supply chain is a persistent and costly problem, and ripeness monitoring is central to addressing it. Strella's approach — continuous, real-time gas sensing deployed across storage, distribution, and retail — generates quality data at multiple points in the chain rather than at a single checkpoint.

With sensors deployed in more than 26 countries, the company has an established international footprint for an early-stage hardware business. This Series A adds capital following more than $11 million raised previously, and brings in a new lead investor in Silver Blue LLC alongside PeakBridge, LeVert Ventures, and Beta Milouot.

For acquirers in agtech, cold-chain logistics, sensor hardware, or food-supply optimization, Strella represents a company with an operating international deployment, a multi-year track record since its 2018 founding, and a data asset built around produce quality as it moves through the supply chain.
