This article covers a £500k funding round on 6 October 2025 at Axenic, a Durham-based manufacturer of advanced optical modulators for satellite communications, founded by Stephen Clements. The round raised £500k, led by NPIF II – Maven Equity Finance with support from the Finance Durham Fund.
Axenic manufactures optical modulators and electronic components for use in satellite and aerospace systems. These devices enable high speed optical communication between satellites, ground stations and aerospace platforms.
Satellite manufacturers and operators need high-speed optical components to enable reliable, high-bandwidth communication in space. Limited specialist suppliers and production capacity make it hard to scale and meet growing demand from customers.
Axenic explains that it develops and supplies specialised optical modulators that enable high-speed space communications for LEO satellites and aerospace. It is scaling manufacturing and investing in capacity and equipment to meet growing customer demand.
Axenic raised £500k in a finance round from NPIF II – Maven Equity Finance and the Finance Durham Fund (both managed by Maven Capital Partners). This makes it the 14th largest funding round in October 2025 (14 recorded). By size, the round comes in 444th for 2025 (486 recorded) in the Startupmag database, as of 6 October 2025.

In the funding announcement, Stephen Clements explained:
Working closely with our wide range of satellite customers, aXenic has been able to build a global reputation for its unique technology, built on decades of world leading engineering expertise within the company. Having reached the point where capacity, equipment and working space is limiting our ability to grow further, we are delighted to have closed this finance round with Maven to support our next stage of growth in the optical satellite communication market.
The company continued that it was seeing strong demand for its devices and that the funding would provide scope to grow alongside the emerging market for the use of optics in space, to bring the equivalent improvement in bandwidth that fibre-optics has brought to the terrestrial communication market.
Axenic is based in Durham, UK.
Axenic operates in the technology sector. The technology sector develops hardware and software to solve problems and improve services. In plain terms, it makes devices and software that help people and businesses connect and work faster.
Key trends and challenges in satellite communications:
Low Earth orbit constellations like Starlink and OneWeb drive demand for optical inter-satellite links. Optical links deliver fibre-like bandwidth between satellites, improving global internet speeds.
Specialised optical modulators and laser components often have long lead times. Small production volumes and complex testing can limit manufacturing scale-up.
International spectrum coordination and orbital slot allocation remain slow and fragmented. Growing satellite numbers increase collision risk and the amount of dangerous debris.
