Company profile
researched Sep 2026Tether EV develops software that predicts and optimizes electric vehicle charging so that private EVs can act as distributed energy storage for the power grid. The company describes its product as a prediction and optimization engine that learns the charging and driving behavior of individual EV drivers and aggregates that flexibility. Its platform functions include identifying and classifying charging users, generating synthetic "digital drivers" to supplement or replace existing datasets, building bottom-up machine learning models of individual and aggregate behavior, producing user reports, and enabling flexible (V1G) charging and vehicle-to-grid (V2G) services that provide ancillary services to the grid.
According to an investor portfolio page, the platform combines cloud-based AI with cloud-to-cloud connectivity to automotive OEMs to enable dynamic charge management, helping users cut costs and increase renewable energy use while integrating with smart grids and flexibility markets. Company descriptions on accelerator job boards state that Tether aggregates the behavior of millions of private EVs to coordinate charging patterns, creating a distributed battery that reinforces the power grid and reduces a vehicle's lifetime CO2 output.
Business model
Tether supplies its prediction and optimization engine as software that integrates into existing charging solutions via an API, positioning itself as an infrastructure layer for charge point operators and vehicle manufacturers rather than an end-consumer charging brand. It is categorized as SaaS in the EU-Startups directory.
Company descriptions state that Tether bids aggregated vehicle flexibility into balancing markets, generating additional revenue streams for partner OEMs and charge point operators, with EV owners earning rewards for participating; the platform also monetizes flexible charging and V2G ancillary services to the grid.
Traction
The company reports ongoing pilot projects with major industry players, and in 2025 it raised €1.3 million according to European startup press coverage. Job boards list the company at 1-10 employees, hiring data science and software engineering roles in Barcelona and Stockholm.
▸Full profile — market position, technology, go-to-market, geography, history
Market position
An early-stage (pre-seed) European climate-tech company working at the intersection of EV charging, predictive analytics and grid flexibility; it is associated with the Techstars and Norrsken startup networks and is backed by the investor Inclimo.
Tether emphasizes a software-only approach that models individual rather than one-size-fits-all driver behavior, builds synthetic driver datasets, and connects directly to OEM clouds, allowing EV flexibility to be aggregated for balancing markets without dedicated hardware.
Technology
Cloud-based AI and machine learning applied to EV charging and energy data, including bottom-up behavioral models of individual drivers, time-series forecasting and pattern recognition, synthetic driver generation, and cloud-to-cloud connectivity with automotive manufacturers. Engineering roles reference AWS services, Python and TypeScript, REST API and network-device integration, power-meter data collection, real-time data processing, and OCPP and IoT protocols for charging infrastructure.
Go-to-market
Tether markets an API-first integration intended to be completed in under one week, positioning its engine as an add-on to existing charging platforms, and states it runs pilot projects with major industry players while focusing on partnerships with vehicle manufacturers and grid operators.
Charge point operators, EV charging solution providers, automotive OEMs and grid/flexibility market participants that want to understand and manage driver charging behavior; indirectly, EV owners who earn rewards for providing flexibility.
Geography
Headquartered in Barcelona, Spain, with a second location in Stockholm, Sweden; an investor listing also records a Delaware, United States entity. The company describes a growing market focus in Europe.
History
Sources place the company's founding in 2022 (an EU-Startups directory entry lists 2020). It has been listed on the Techstars and Norrsken job boards, and appears in the portfolio of investor Inclimo. In June 2025 European startup media reported a €1.3 million raise.
