Overview

CTO / Technical Co-Founder - ClimateTech SaaS (Equity Only). Hybrid - UK (Preferred) / Europe.

A mission-driven ClimateTech startup is seeking a technical co-founder to lead development of an AI-powered SaaS platform revolutionizing biomethane production. We’re targeting a 30% increase in renewable gas output, 20% OPEX reduction, and full transparency into the performance of waste-to-energy systems. Our early traction in the industrial decarbonisation space is strong, and we’re gearing up for a pre-seed raise in late 2025.

The Problem: Organic waste is a 70-billion-tonne global issue, contributing to ~20% of GHG emissions. Biomethane is a scalable, immediately viable decarbonisation solution—but current systems are inefficient, under-digitalised, and data-poor.

The Opportunity: We’re building a SaaS platform powered by AI, Digital Twins, and Industrial IoT to help waste treatment plants and anaerobic digesters optimize operations in real time, unlock actionable insights, and scale biomethane production with confidence.
