KAUST Spinout Terraxy Raises $3M to Take Desert Soil Regeneration From Lab to Industrial Scale
Backed by Aramco's Wa'ed Ventures and KAUST, the Seed-2 round funds a 30,000-square-meter production facility in Al Zulfi — a concrete step in moving university-born soil technology into commercial deployment.
The Round at a Glance
Terraxy, a startup spun out of research at King Abdullah University of Science and Technology (KAUST) in Thuwal, has closed a $3 million Seed-2 funding round. The round was led by Wa'ed Ventures, the venture capital arm of Saudi Aramco, with additional participation from KAUST itself.
The company develops technology aimed at restoring the efficiency of degraded soils in arid environments, improving how sandy soils retain water and nutrients. Terraxy's proprietary soil enhancer, reported under the name Carbosoil, is described by the company as capable of durably storing carbon in soil while improving plant growth and yield with the same water and nutrient inputs.
Key Takeaways
- Terraxy, a KAUST spinout based in Thuwal, raised $3M in a Seed-2 round led by Wa'ed Ventures, Aramco's venture capital arm, with KAUST also participating.
- The capital funds Terraxy's shift from pilot to industrial-scale production, anchored by a new 30,000 m² commercial facility in Al Zulfi.
- Terraxy's soil enhancer is reported to improve plant growth and yield by up to 70% using the same water and nutrient inputs — a figure sourced from company and investor statements, not independently audited by SFT.
- The technology has moved through Saudi Arabia's MEWA Regulatory Sandbox, which allows emerging environmental technologies to be tested under real-world conditions.
- The deal illustrates a broader MENA investment pattern: capital increasingly flowing toward the soil and water layer that underpins agriculture in arid climates, ahead of the crop itself.
Why This Round Matters Beyond Its Size
At $3 million, the round is modest in absolute terms. Its significance lies elsewhere: it marks the transition of a technology developed inside a Saudi university from experimental production to a dedicated commercial facility — one of the clearer lab-to-industry pathways to emerge from KAUST's spinout pipeline to date.
Saudi Arabia's terrain is dominated by sandy, low-organic-matter soils that struggle to retain water and nutrients, a structural constraint on agriculture, landscaping and large-scale greening efforts. Reported estimates cited across coverage of the round suggest that roughly a third of the world's soils are degraded, with arid regions among the most exposed. Terraxy's technology is positioned to address that constraint directly, ahead of decisions about what to plant or how to irrigate.
"-We see Carbosoil as an integral part of soil enrichment and assisting with the ambitious goals of the Saudi Green Initiative and enhancing the carbon credit economy."
From University Lab to Commercial Facility
The technology traces back to research led by Prof. Himanshu Mishra at KAUST, alongside then-PhD researcher Adair Gallo, who spent years working through a stubborn technical obstacle: biochar's promise as a soil amendment kept running into its high pH and chemical incompatibility with desert soils. SFT profiled that journey — from lab breakthrough to founding decision — in a founder story published last year, which is worth revisiting now that the company has reached this funding milestone.
Terraxy will use the new capital to move beyond pilot-scale production toward full industrial manufacturing, supported by the new Al Zulfi facility. That shift — from validated prototype to a dedicated production site — is typically the hardest step for deep-tech spinouts to fund, and it is the step Wa'ed Ventures and KAUST are backing here.
The company's path has also run through formal regulatory testing: Terraxy has progressed through the Ministry of Environment, Water and Agriculture's (MEWA) Regulatory Sandbox, a framework that allows emerging environmental technologies to be validated under real-world conditions before wider deployment. That step gives the round a layer of institutional validation beyond the capital itself.
Land degradation and carbon removal are treated here as one problem, not two — a framing that is increasingly shaping how Saudi investors evaluate agri- and climate-tech.
SFT Editorial AnalysisWhy It Matters for MENA
The round sits at the intersection of two priorities central to Saudi Arabia's Vision 2030 agenda: strengthening food security through domestic agricultural capacity, and building out the Kingdom's carbon management and land-restoration ambitions under the Saudi Green Initiative. Soil technologies that improve water and nutrient retention address a structural constraint on both.
Wa'ed Ventures' involvement is also notable in its own right. As Aramco's venture capital arm, its backing signals that deep-tech, university-originated environmental technology is increasingly viewed as investable by Saudi Arabia's largest corporate capital pools — not only by dedicated climate or agri-focused funds. For food and agriculture businesses operating in arid MENA markets, a validated, locally developed soil-enhancement technology moving toward industrial supply is a development worth tracking as a potential input, rather than only as a climate story.
What We're Watching
Two questions will determine whether this round marks a genuine inflection point rather than an incremental one. First, whether Terraxy can demonstrate its technology's impact and cost profile at commercial scale, not just in pilot and sandbox conditions. Second, whether its agricultural applications gain ground alongside its currently more prominent use cases in landscaping and carbon capture — the latter being where much of the public attention on the company has concentrated to date.
