Facebook Co-Founder Eduardo Saverin's B Capital Raises $500M to Back AI in Robotics, Defence and Orbit

B Capital, the global multi-stage investment firm co-founded by Facebook co-founder Eduardo Saverin, has announced the final close of B Capital Ascent Fund III at its hard cap of $500 million in aggregate commitments. The fund was oversubscribed and drew capital from both existing and new limited partners, according to the firm, and represents close to double the $254 million raised for its predecessor, Ascent Fund II, which closed in July 2022.

The vehicle is dedicated to early-stage investing, concentrating on the Seed, Series A and Series B rounds of companies developing next-generation technologies across healthcare, enterprise, energy and what the firm describes as the next frontier. Its geographic remit spans key innovation hubs in North America and Asia, a footprint that reflects B Capital's integrated team across nine locations in the US and Asia and its strategic partnership with Boston Consulting Group.

The wider significance of the close sits less in the headline number than in what a $500 Million early-stage fund closing above its target reveals about the current state of venture capital. Limited partners have grown considerably more selective since the correction of 2022 and 2023, with capital concentrating in a smaller number of managers able to demonstrate genuine sector depth. An oversubscribed close in that environment indicates that institutional allocators are prepared to commit at scale to a specific thesis, that the next generation of category-defining companies will emerge as AI reshapes the world's largest industries rather than as standalone software plays.

"We're grateful for our limited partners' continued confidence in B Capital as we closed Ascent Fund III at our $500 million hard cap," said Raj Ganguly, Co-Founder and Co-CEO of B Capital. "Their backing reflects a shared conviction that the next generation of market-leading companies will emerge as AI reshapes the world's largest industries. This Fund advances our multi-stage platform, partnering with exceptional founders early and supporting them with capital and operational expertise at every phase of growth."

That conviction is echoed across the firm's leadership. "AI is creating extraordinary opportunities across every industry," said Howard Morgan, Chair and General Partner at B Capital. "We believe the Fund is well positioned to capture this moment through our deep sector expertise, strong investor relationships and global reach. Central to our approach is an investment philosophy grounded in the fundamentals: backing outstanding entrepreneurs early and being a true partner over the long term."

The early portfolio points to a deliberate concentration in physical AI rather than software alone

Ascent Fund III has already deployed into more than 20 companies spanning AI infrastructure, robotics, healthcare and frontier technologies, and the identity of the three companies the firm has chosen to name clarifies the strategy. Apptronik, Havoc AI and Star Catcher cluster around AI applied to hardware, defence and energy infrastructure, the capital-intensive domains where the technology intersects with the physical world rather than remaining confined to the screen.

"We have entered a technology cycle that is reshaping industries and business models worldwide," said Eduardo Saverin, Co-Founder and Co-CEO of B Capital. "The most meaningful opportunities will not come from technology alone, but from entrepreneurs applying AI to transform industries such as healthcare, enterprise, energy and the next frontier. With support from our own proprietary AI platform, this Fund will help founders turn bold, breakthrough ideas into enduring businesses with global impact."

The trajectory of those companies since B Capital's initial investments illustrates why early positioning matters in the current cycle. Apptronik, the Austin humanoid robotics company that B Capital co-led at Series A, went on to raise a $520 million extension in February that lifted its total Series A funding beyond $935 million and valued the business at more than $5 billion, roughly triple its earlier valuation, according to reporting by CNBC and Bloomberg. The raise arrived amid a broader surge in the segment, with humanoid robotics startups attracting $6.1 billion across 139 deals in 2025, a more than 300% increase in deal value from the prior year, according to PitchBook data.

The defence-technology holding tells a parallel story. Havoc AI, the maritime and multi-domain autonomy company backed by B Capital, closed an $85 million round in October and followed it with a $100 million Series A in May, taking its total capital raised beyond $200 million since its founding in 2024, according to figures reported by The Robot Report and Crunchbase. The company has delivered more than 30 autonomous vessels to the US Department of Defense, a marker of the demand pulling capital into defence autonomy as governments absorb the operational lessons of recent conflicts.

Star Catcher completes the picture, and it demonstrates the breadth of what B Capital counts as an early-stage opportunity. The Jacksonville company is building what it describes as the first power grid in orbit, a constellation designed to harvest solar energy and beam it via optical lasers to other spacecraft, lifting the power ceiling that constrains every satellite currently in service.

B Capital led the company's oversubscribed $65 million Series A in May, co-led by Shield Capital and Cerberus Ventures, which brought Star Catcher's total capital raised to $88 million, according to the company's announcement. The startup has signed seven power purchase agreements and is managing a commercial pipeline it values at more than $3 billion in projected annual recurring revenue, evidence of demand forming around a service still awaiting its first in-space demonstration.

The pattern running through all three holdings is one of rapid follow-on financing, and it substantiates the argument B Capital advances about the value of entering early. Apptronik, Havoc AI and Star Catcher have each raised substantial subsequent rounds to accelerate commercialisation, expand manufacturing and scale their technologies, which compresses the interval between an early cheque and a marked-up position. For a fund concentrating on Seed through Series B, that velocity is the mechanism through which conviction converts into return.

The firm has also pointed to its own internal tooling as a differentiator, with Saverin citing a proprietary AI platform intended to support portfolio founders, a sign of how investment managers are beginning to apply the technology to their own operations rather than merely funding it in others.

The decision to concentrate on North America and Asia carries strategic weight at a moment when AI development is increasingly organised around those two poles. By maintaining an integrated presence across both regions, B Capital places itself to source companies and channel capital across the geographies where the foundational technologies of the next industrial cycle are being built, an approach that distinguishes it from managers anchored to a single market.

Founded in 2015, B Capital now manages more than $12 Billion in assets across multiple funds, investing from seed to late-stage growth primarily in the technology, healthcare and climate sectors. Its wider portfolio includes Perplexity, Precision Neuroscience, Axiom and Fervo Energy, a spread that maps closely onto the sectors Ascent Fund III has been raised to pursue, and one that underlines the continuity between the firm's established positions and the early-stage thesis it is now funding at scale.
