The most valuable data point on a farm is the one that gets away. It’s the precise yield of a single square meter, lost in the roar of a combine harvester and averaged out across an entire field. For years, capturing that data meant buying a new, quarter-million-dollar machine from John Deere or buying into a complex, proprietary sensor ecosystem. The team at Green Growth, a startup based in Riga, Latvia, decided there was a simpler way: a box of sensors you bolt onto the harvester you already own.
Founded in 2021 by Alfiya Kayumova and Dr. Evgeny Savin, Green Growth sells the Yield Monitor, a system that combines optical sensors, GPS, and software to map crop yields in real time [FinSMEs, May 2022]. The hardware is designed to mount on existing agricultural machinery, and the company claims it can be installed in about two hours [Retrofit Yield Monitor for Any Combine Harvester | Green Growth, retrieved 2026]. For a farmer, the promise is straightforward. Instead of guessing why one corner of a field underperforms, they get a color-coded map showing exactly where the potatoes, wheat, or barley came up thin, allowing them to adjust fertilizer, seed, or irrigation with surgical precision next season.
The retrofit wedge
The company’s entire bet hinges on a single, pragmatic insight. The global fleet of combine harvesters is vast, old, and expensive to replace. Convincing a farmer to buy a new combine for its data capabilities is a non-starter for most. Convincing them to spend a few thousand euros on a bolt-on kit that works with their existing Claas, John Deere, or Fendt is a different conversation [Tech.eu, May 2022]. Green Growth’s product is built around this retrofit premise, aiming to be the universal adapter for yield data.
Their published compatibility list is a roll call of global agriculture, from common cereal harvesters to specialized potato and sugar beet equipment from brands like Grimme and Ropa [International Fertilizer Association, June 2026]. This agnostic approach is their wedge into a market dominated by original equipment manufacturers (OEMs) who traditionally keep data locked inside their own brand ecosystems.
The team and early traction
The founders bring a mix of field and lab experience to the problem. CEO Alfiya Kayumova is described as a family-farm owner with a background in international agritech business development [F6S company profile]. Her co-founder, Dr. Evgeny Savin, is a physicist with a PhD and product management experience [F6S company profile]. It’s a pairing meant to bridge the gap between the practical realities of farm operations and the technical demands of sensor hardware and data processing.
They’ve used a relatively modest war chest to prove the concept. The company has raised a total of $300,000 in pre-seed funding, led by New Nordic Ventures [AgFunderNews, August 2023]. With that capital, they’ve focused on product development and early customer acquisition.

| Pre-seed (total) | $300,000 | New Nordic Ventures & others | 2022 [AgFunderNews, August 2023] |
By August 2023, the company reported it had accumulated more than 50 contracts with what it called "leading agritech dealers and farmers" [AgFunderNews, August 2023]. The path to those deals appears to be twofold: selling directly to larger farming operations and partnering with agricultural equipment dealers who can bundle the Yield Monitor as an add-on service.
The path to impact
In climate tech, the unit of progress is often the ton of CO2 avoided. In agritech, it’s the kilogram of nitrogen fertilizer not wasted. The logic for a product like the Yield Monitor is that by showing a farmer exactly where a field is underperforming, they can reduce input use in those zones. Less over-application means lower costs for the farmer and less agricultural runoff into waterways.
The potential scale is significant, if the data is actionable. A back-of-the-envelope calculation: if a single 100-hectare farm reduces its nitrogen fertilizer use by just 5% through targeted application, that’s roughly 1,500 kilograms of fertilizer saved per season. Multiply that by thousands of farms, and the environmental arithmetic starts to justify the hardware’s existence. The real test for Green Growth will be proving that their maps lead to those tangible input savings, not just pretty pictures.
Where the wheels could come off
The retrofit market is attractive but comes with its own set of challenges. The competitive landscape includes:
- The OEM giants. Companies like John Deere are increasingly baking advanced telematics and yield mapping into their new equipment, creating a premium, integrated experience that a retrofit can’t match.
- The platform plays. Larger farm management software platforms could see yield data as a feature to build or acquire, potentially squeezing out standalone hardware vendors.
- The complexity of simplicity. The promise of a two-hour install is compelling, but farmers are notoriously hard on equipment. Ensuring the sensors survive dust, vibration, and all-weather operation across countless machine models is a relentless engineering challenge.
Green Growth’s answer, for now, is to stay focused on its niche: the farmers who cannot or will not buy a new combine, and the high-value specialty crops like potatoes where OEM solutions can be lacking. Their early contracts suggest there’s demand. The next phase will be about moving from dozens of contracts to hundreds, and proving that the data they provide changes farming practices in a measurable way.
For Green Growth to become a lasting fixture, it must do more than just attach to a John Deere. It must become the reason a farmer doesn’t feel the need to upgrade to the latest model just for the dashboard. That’s a harder retrofit to engineer.
