Meet the Team

  • Alexander Rennie

    Founder // Director

    Ascension was born from a passion for technological advancement and the belief that the right talent can change the world. With 5+ years experience working in clean tech recruitment and start-up ecosystems, Alex identified two major bottlenecks preventing projects from reaching their full potential—talent and capital.

    Ascension goes beyond the standard recruitment model, acting as a strategic growth partner to early-stage and scaling start-ups, helping to secure the talent and investment they need to grow. Through our extensive network, deep market knowledge, and hands-on approach, we empower companies to overcome the barriers of finance, technical complexity, and regulation to build a greener, smarter, and more efficient future.
