Silicon Valley VCs back Saudi fintech as market shifts from emerging to proven

Saudi Arabia's fintech sector is attracting major Silicon Valley investors, signalling the market has matured from emerging opportunity to proven growth story. Andreessen Horowitz recently invested $25 million in Saudi startup Stitch, marking its first GCC deal, whilst General Catalyst, Sequoia Capital and PayPal Ventures have backed other Saudi fintechs. Digital payments now account for 79% of retail transactions in Saudi Arabia, with licensed fintech firms jumping from 80 in 2022 to over 280 by mid-2025. The sector is valued at $2.85 billion in 2025 and forecast to reach $5.28 billion by 2030. International investors now represent over half of Saudi venture capital participants, up from under a fifth in 2020. Experts say the real opportunity lies in infrastructure rather than consumer apps, with open banking and cross-border payment systems positioning Saudi fintech as a bridge between emerging trade corridors.

Unconventional AI raises $475M at $4.5B seed valuation to cut AI power costs by 1,000 times

Unconventional AI has raised $475 million at a $4.5 billion valuation in what's framed as the largest seed round ever, backed by Andreessen Horowitz, Lightspeed and Sequoia Capital. The company, founded by Naveen Rao, is developing oscillator-based chips that could reduce AI inference power consumption by up to 1,000 times. The pre-revenue startup released Un-0, an image generation model running on a simulation of its architecture, as proof the approach can replicate conventional AI workloads. Unconventional plans to release chip schematics soon, targeting a system-on-chip tape-in in 2026 and mass delivery in 2027. Rao previously co-founded Nervana Systems, acquired by Intel for $400 million, and MosaicML, acquired by Databricks for $1.3 billion. The funding addresses growing concerns about AI's energy consumption, with data centres projected to exceed 1,000 TWh by late 2026.

US Army awards $99M contract to startup for combat logistics that work when satellites are jammed

The US Army has awarded Rune Technologies a five-year, $99 million indefinite delivery, indefinite quantity contract for its TyrOS logistics platform, which addresses a critical weakness in military supply chains: the ability to function when satellite communications are jammed. TyrOS is designed to operate offline on laptops in forward positions under electronic attack, synchronising data when connectivity returns via radio, satellite or cellular networks. The platform integrates fuel, ammunition, food and spare parts inventory with vehicle status, transport routes, terrain threats and weather data, generating automated resupply recommendations. The system is already deployed with the 25th Infantry Division, 4th Infantry Division, XVIII Airborne Corps and Marine Corps units. Rune previously raised $24 million in Series A funding led by Human Capital, with participation from Andreessen Horowitz and Point72 Ventures.
