Seraphim Space Investment Trust Targets Series B Growth After £137M Raise

The London-listed trust leverages a 20.1% surge in net asset value to scale its growth-stage space technology portfolio.

TechNewsReel Newsroom · August 4, 2026

Seraphim Space Investment Trust (SSIT) has entered a strategic capital deployment phase following a successful £137 million fundraising round. The move signals a concerted effort to capitalize on the accelerating maturation of the global space technology sector, shifting focus toward companies capable of rapid scaling.

The trust secured the £137 million through a C-share offering, which integrated an institutional placing, a retail offer, and direct subscriptions. This capital injection arrives as the fund reports a 20.1% increase in its net asset value (NAV) for the six months ending December 31. This growth reflects strong momentum across the trust's existing portfolio and a broader surge in demand for orbital infrastructure and defense-related technology.

Strategic Focus on Series B

Unlike early-stage venture capital, the trust is specifically targeting growth-stage space technology companies. Mark Boggett, CEO of Seraphim Space, noted that while the firm operates three funds across the capital stack, the publicly listed investment trust is focused on companies at the Series B level. This stage of investment typically targets companies that have moved past the proof-of-concept phase and are scaling their operations to meet commercial or governmental demand.

By focusing on Series B, SSIT aims to mitigate the high risks associated with seed-stage ventures while capturing the value creation that occurs as companies transition into established market players. This approach allows the trust to invest in proven technologies that are now ready for industrial-scale deployment.

Market Implications

This aggressive pursuit of growth-stage assets reflects a broader shift in the UK space-tech capital market. The ability to raise significant capital despite global economic volatility suggests a robust investor appetite for the sector. The strategic importance of space technology in national defense and critical infrastructure is creating a valuation uplift for maturing companies, making Series B investments particularly attractive for institutional and retail investors seeking exposure to the orbital economy.

Future Outlook

As the trust continues to deploy its new capital, the industry will be watching for the specific companies added to the portfolio and how they leverage the current trend of increased defense spending. While the fund's NAV growth indicates a strong trajectory, the long-term success of the deployment will depend on the ability of these growth-stage firms to transition from strategic contracts to sustainable, scalable commercial operations. The trust's ability to identify these winners will determine if the current valuation uplift translates into long-term shareholder returns.
