The 5 Finalists in "Innovative World Technology" 2025
This category targets technologies outside conventional frameworks — next-generation infrastructure, novel business models, and deep science. Each of the five finalists is tackling a different industry challenge, with strong deeptech elements: hard science and hardware at the core.
1. ChakraTech — Transforming Greenhouse Gases into Biomaterials Using Ancient Microbes
Overview
ChakraTech is a San Diego-based cleantech company. Using the metabolic capabilities of microorganisms that have existed since ancient times, they have developed a process to produce biodegradable plastics (bioplastics) from waste greenhouse gases — methane and carbon dioxide. The goal: reduce dependence on petroleum-derived plastics and lower environmental load.
The Problem
Modern society faces a double environmental challenge: accumulated plastic waste and greenhouse gas emissions. Conventional plastics are nearly indestructible and remain in nature as microplastics, while greenhouse gases drive climate change. ChakraTech addresses both simultaneously — bioplastics that naturally degrade within a year of disposal, produced from low-cost waste gases.
Solution and Technology
The company grows specialized microorganisms in large bioreactors and has developed a production process that uses greenhouse gases as raw material. Conventional bioplastics require expensive carbon sources like sugars and vegetable oils; ChakraTech's use of waste gases as a cheap, abundant feedstock is a significant structural advantage. Environmental responsibility and economic viability become compatible.
Business Model
As technology validation progresses, ChakraTech plans to monetize through direct sales of bioplastics and licensing of the production process. Carbon credits and environmental regulatory benefits are also in scope.

The vision of "solving two environmental problems simultaneously" was highly evaluated.
2. Expanso — Opening New Frontiers in Data Processing Through Distributed Computing
Overview
Expanso is a Seattle-based startup providing a platform to efficiently process data distributed across locations from cloud to edge. Their flagship product, "Bacalhau," takes a new approach: rather than moving data to a central location, computation happens where the data is generated.
The Problem
Conventional big data processing requires massive network bandwidth and time to centralize and manage data. Real-time processing of data generated at remote locations and edge environments is a persistent challenge. Expanso eliminates the inefficiency of data movement and enables high-speed local processing, accelerating decision-making and reducing operational costs.
Solution and Technology
The Bacalhau platform provides agents deployed at each site to collect and process data locally. An AI-powered job scheduler determines optimal processing locations and integrates compute resources across regions. Compared to conventional cloud-centric processing, this dramatically reduces network transfer volume and improves response times. The engineering team brings experience from Google, Microsoft, and other major cloud providers.
Business Model
Expanso is considering a multi-track revenue model based on open-source Bacalhau: paid enterprise support, management tools, and cloud service offerings. $7.5M seed funding has been secured; enterprise expansion is the next priority.

The CEO explained that Expanso complements — rather than competes with — existing cloud services, providing a proprietary distributed processing layer. Multi-cloud and on-premises integration was highlighted as the core differentiation.
3. Fast Sense — Gas Sensors for the Hydrogen Economy
Overview
Fast Sense is a Tel Aviv-based hardware startup. They have developed technology that mounts multiple nanosensors on a semiconductor chip, enabling real-time quantitative analysis of hydrogen, methane, and other components in gas mixtures. A palm-sized sensor can measure gas components with high precision — previously requiring large equipment.
The Problem
As the hydrogen economy gains global momentum, existing gas measurement equipment struggles with hydrogen leak detection and accurate quantification of mixed gases. Hydrogen is colorless and odorless, making leaks particularly hard to detect. In natural gas/hydrogen blended transport, conventional measurement methods often lack sufficient precision. Fast Sense aims to "make invisible hydrogen visible," improving energy safety and efficiency.
Solution and Technology
The sensor uses multiple sensor pixels created through laser printing technology, each pixel responding selectively to a specific gas. This enables accurate concentration measurement of hydrogen, methane, and other components even in mixed gas environments, preventing cross-sensitivity interference. Low power consumption, compact form factor, and wireless real-time cloud data transmission with web-based monitoring complete the package.
Business Model
Target customers include gas suppliers, energy companies, and industrial plants. Hardware device sales plus monitoring service subscriptions. Government-supported hydrogen programs and international standardization initiatives create significant market expansion tailwinds.
