Capella Space shifts to low-cost commercial satellites after $19M Series B

Capella Space began as a two‑year‑old startup offering defense‑grade synthetic aperture radar (SAR) satellites that were the size of a school bus and cost hundreds of millions of dollars, limiting their use to government and intelligence clients. The high price and bulk made frequent revisits impossible for commercial users who needed timely data on infrastructure, agriculture, or disaster response.

CEO Payam Banazadeh decided to miniaturize the SAR satellites to backpack‑size, 37‑kilogram units costing low single‑digit millions, thereby enabling hourly imaging and a commercial Earth observation service. The $19M Series B led by Spark Capital and DCVC funded prototype launches, hiring, and a plan to deploy a 36‑satellite constellation for global hourly coverage.

Secured $19M Series B funding, validated miniaturized satellite design, and positioned to capture commercial Earth observation market with hourly imaging capability

Traditional radar satellites were too expensive and large for commercial customers, creating a market gap.

Miniaturization lowered cost and revisit time, meeting demand for timely, all‑weather Earth data.

Pre‑sale commitments and investor confidence showed a viable commercial pathway.

Expanding beyond defense to infrastructure monitoring aligned with the company’s vision of saving resources and lives.

Identifying and overcoming cost and size barriers can unlock new market segments for deep‑tech hardware startups

After the Series B, Capella launched its first prototype satellite in mid‑November 2018 and a second in June 2019, began commercial imaging trials, grew its team to about 60 employees, and continued to raise additional funding to build out its constellation. The company now serves defense, blue‑chip firms, and NGOs with on‑demand SAR data.
