Why are we excited about them?

The telephony market has evolved and with the introduction of VOIP (Voice Over Internet Protocol) Aircall drives value to its customers through actionable analytics, sentiment analysis and now AI applications. Its early adoption into the call centre market positions it as a pioneer in the space having deep longstanding customer relationships and expansion potential. Founded in 2014, Aircall moved from six-month hyper-growth in 2016 to a world leading all-in-one customer communication and intelligence platform. Throughout the years, it has scaled headcount, offices (NYC, London, Sydney, Madrid, Berlin, San Francisco), and funding (Series D) while surpassing $175 million ARR in 2025 and weaving AI into its core products.

Molten Ventures Growth Fund First Close

Molten Ventures announces the first close of our Growth Fund at £175 million, including a £75 million cornerstone commitment from the British Business Bank. 

“There is no shortage of exceptional founders or technology businesses in the UK and Europe; what they too often lack is sufficient growth capital to help them become global leaders. This Fund gives Molten greater firepower to back our highest-conviction companies at Series B and beyond, build meaningful ownership positions and channel capital into the next generation of growth.” -
