PomegraEstonia's Golbriak Space closed a €4M seed round on October 8, 2026, to move its satellite laser communication terminals from engineering work to serial production.
Key Takeaways
- Golbriak Space raised a €4M seed round, co-led by Join Capital and PhotonVentures, with Takeoff participating.
- The Tallinn company targets 200 terminals a month, up from double-digit annual output.
- Valuation is undisclosed; prior funding was about $130,000, so this is a large step up.
Lead
Golbriak Space, a Tallinn-based maker of optical communication terminals, announced a €4M (about $4.5M) seed round on October 8, 2026. Join Capital and PhotonVentures co-led it, and the Takeoff accelerator also took part. The company will spend the money on industrialization, more production capacity, a new Tallinn lab and office, and hiring. Valuation was not disclosed.
What Does Golbriak Space Actually Build?
Golbriak builds laser terminals that move data between satellites, aircraft and ground stations using light instead of radio. Its two products are ERMESAI+, a terminal for spacecraft, and ARES, a variant for airborne platforms such as drones. Both share a software-defined architecture.
The company says its design tolerates coarser pointing from the host platform than competing designs, which eases integration and lets several terminals run on one spacecraft or aircraft. Current data rates start at 2.5 Gbps, and a 10 Gbps system is planned for 2027. The hardware can be configured to standards from the US Space Development Agency, the Consultative Committee for Space Data Systems and ESTOL.
Golbriak was founded in 2017 by Nicola Garzaniti, who serves as CEO, and Simone Briatore. It has also sold an optical downlink service, priced at €18 per minute at 1 Gbps.
How Big Is the Jump From Prior Funding?
The jump is steep. The company's earlier funding totaled roughly $130,000 across two rounds, including a convertible note from Plug and Play Turin in July 2023. A €4M seed is about 30 times that sum.
The size reflects the shift in what the company is selling. A few years of prototype work and small orders needed little capital. A production line does not. Hardware makers in this segment tend to burn cash on test equipment, clean-room space and inventory before volume orders arrive, and €4M buys a limited amount of each.
Why Are Investors Backing Laser Terminals Now?
Investors are backing laser terminals because satellite constellations need links that radio cannot supply at scale. Optical links carry more data per terminal and are harder to intercept, and the market is growing. One estimate puts optical satellite communication at $0.62B in 2025, rising to $1.56B by 2030, a 20.4% compound annual growth rate.
Supply is the constraint. Defence and commercial operators plan constellations that need thousands of terminals, and few European suppliers can build them in volume. Mynaric, the German manufacturer and a direct competitor, was acquired by Rocket Lab in April 2026. That deal left Golbriak among the smaller independent European players in the segment.
Join Capital's Jan Borgstädt said Golbriak has functioning technology, paying customers and clear demand from operators. Garzaniti said the company has paying customers and demand expanding toward programmes involving thousands of terminals. Customer names and contract values were not disclosed, so that demand cannot be checked independently.
What Does the Production Target Imply?
The target implies an industrial ramp that a company of this size has not yet shown. Golbriak builds double-digit numbers of terminals a year today. It aims for 200 per month, and 300 to 400 per month over the longer term. Even the first target is a jump of roughly two orders of magnitude.
Hitting that rate depends on supplier capacity for lasers, optics and precision pointing components, and on qualification schedules that customers control. A seed round alone will not fund a 200-a-month line, so a Series A is a probable next step. The terminals' pointing tolerance, if it holds up in orbit, could lower the cost of getting there.
Competitive Context
Rocket Lab's absorption of Mynaric shows that launch and spacecraft integrators want optical communications in-house. That trend squeezes independent suppliers: they can sell to many constellation builders, but a buyer with its own terminals is a lost customer. It also makes smaller suppliers acquisition targets, which may figure in how investors read this round.
Golbriak's pricing and standards compatibility aim at the opposite approach. By supporting multiple interoperability standards, it can sell to operators who want a second source rather than a captive supplier.
Outlook
Golbriak enters its production phase with €4M, a new Tallinn facility planned and a target of 200 terminals a month. The key tests are whether it can deliver the 10 Gbps system in 2027, convert discussions covering thousands of terminals into signed contracts, and secure follow-on capital before the new production line outgrows the seed round.
