Tether Raises $1.5M to Turn EVs into Grid-Stabilizing Powerhouses

We just raised $1.5M.

Every EV owner faces an uncomfortable reality: 

↳ Your car sits parked 95% of its lifetime 
↳ Contains 50-100+ kWh of unused battery capacity 
↳ While the grid struggles with renewable energy chaos

Luis Medina Rivas saw this waste firsthand as a solar engineer.

Projects getting cancelled due to grid instability. 
Meanwhile, massive EV fleets parked under solar panels. 
Just... sitting there.

That's when it clicked: Cars are batteries on wheels.

Tether was born.

How does it work: 
↳ AI-powered software integrates directly with EV manufacturers 
↳ Transforms parked cars into a decentralized battery network 
↳ Sells energy back to the grid to stabilize it 
↳ Operates seamlessly in the background (no driver interaction needed)

The breakthrough? 

Everyone wins: 
↳ Grid operators get access to a massive battery 
↳ EV manufacturers earn up to €2 per car per day 
↳ Saves 3,700 metric tons of CO2 per MW over a car's lifetime
↳ Reduces EV battery degradation by 30% due to smart charging

The impact could be massive: 
↳ 9 million EVs already on EU roads (130M by 2035) 
↳ €50B+ opportunity in grid balancing markets (EU+US) 
↳ Could replace expensive stationary storage solutions

From witnessing solar project cancellations... to potentially revolutionizing how we stabilize the renewable grid.

The solution to grid instability might already be sitting in your driveway.
