Lumen Orbit, a pioneering startup aiming to establish data centers in outer space, successfully secured its latest seed funding within just a few days, fueled by keen interest from investors.
Based in Redmond, Washington, the company finalized an $11 million seed round, achieving a valuation of $40 million. This validates earlier TechCrunch reports indicating that the startup had secured a sought-after double-digit investment round, marking it as one of the standout ventures from Y Combinator’s Summer 2024 cohort. The funding was spearheaded by NFX, with General Partner Morgan Beller set to join the company’s board, alongside contributions from VCs like Fuse.VC, Soma Capital, and scout funds from Andreessen Horowitz and Sequoia, among others.
Philip Johnston, co-founder and CEO of Lumen Orbit, shared with TechCrunch that the exceptional investor interest — with over 200 VCs expressing enthusiasm for the startup — has led the company to initiate an additional SAFE round at a higher valuation to accommodate more investors.
This is a remarkable level of attention for a company that was established just this January.
Lumen Orbit is focusing on creating orbital data centers constructed from pods, each capable of holding computing capabilities and deployable independently, attaching to massive solar panels in clustered arrays in space (see concept image above). The company’s objective is to develop multi-gigawatt computing clusters by the decade’s end, employing high-bandwidth optical lasers for data transmission back to Earth.
If successful, Lumen’s innovative technology could enable AI firms to scale operations without the typical limitations imposed by terrestrial data center sizes and energy constraints, offering a far more cost-effective solution.
“Rather than spending $140 million on electricity, you can invest $10 million in a launch and solar energy,” Johnston pointed out.
The company plans to deploy a demonstration satellite featuring Nvidia’s terrestrial GPUs in May, followed by another test satellite that’s expected to be 100 times more powerful the next year. Johnston mentioned their goal to launch at least annually.
“While many space enterprises take five years to launch, we are targeting an 18-month timeline,” Johnston stated. “We prefer frequent launches with incremental adjustments rather than waiting five years for a single extensive launch.”
Johnston and co-founder Ezra Feilden, CTO, conceptualized the company during their time in the space sector. Feilden brings a decade of satellite design experience from companies like Airbus Defense and Oxford Space Systems, while Johnston has consulted for national space agencies in the Middle East and is a former founder of Opontia, a startup focused on scaling digital brands in the region, which was acquired in late 2023.
As satellite launch costs decrease, Johnston noted their initial thoughts on space solar as an intriguing market niche. However, the challenges associated with transmitting solar energy back to Earth soon became apparent.
In contrast, data centers are advantageous as they do not need to transmit energy back. Instead, they utilize solar energy on-site and remain stationary, effectively addressing the cooling issue naturally, thanks to the coldness of deep space.
After the initial concept was formed, Johnston and Feilden were introduced to Adi Oltean, who was then an engineer at SpaceX and had independently conceived a similar idea. Oltean joined the startup shortly after its inception as a co-founder and chief engineer.
The conversation around constructing data centers in space, as well as in the deep ocean, is increasingly pivotal for facilitating AI’s scalable potential. Key figures in the AI community, from Bill Gates and Sam Altman to Elon Musk, have suggested this approach as a viable solution to the escalating demands for data centers and energy.
Axiom Space is also advancing efforts to develop orbital data centers, though the competitive landscape remains relatively sparse — at least for the moment. However, as the desire for innovation in this area grows, the scenario may soon change.
Lumen’s audacious mission hinges on the continued decline in satellite launch costs, which must remain sustainable for the project to succeed. If they achieve their goals, it could significantly enhance AI’s ability to scale efficiently while minimizing some adverse effects on the Earth’s climate.
