The Startup Battle by Challenger Sustainability Accelerator brought together founders, innovators, and ecosystem representatives in Kyiv for an evening of live startup pitches, expert feedback, and networking around sustainability-driven innovation. Four startups presented their solutions, with Soily.World winning two tickets to IT Arena 2026.

Challenger Sustainability Accelerator will host a Startup Battle, bringing together Ukrainian sustainable tech startups for a live pitching competition.

Ukrainian startups participating in the Challenger Sustainability Accelerator will have an opportunity to receive additional support from the Ukrainian Startup Fund, which will award $75,000 in AWS credits to the top three teams. The credits are aimed at helping startups scale faster, reduce infrastructure costs, and reinvest resources into further growth.

Challenger launches the Sustainability Accelerator – a new equity-free three-month acceleration program for Ukrainian startups working in the fields of green tech, energy, mobility, construction, demining, and prosthetics.

As part of Challenger 4.0, we hosted an internal Startup Roast for our EdTech, HealthTech, and AI startups.
