Billionaire Eduardo Saverin’s B Capital Doubles Assets to $12 Billion

Billionaire Eduardo Saverin’s B Capital has doubled its assets to more than $12 billion by raising separate funds for each stage of a company’s growth. In a venture market dominated by a few AI giants and record secondary trading, the firm’s model shows both how mid-sized investors can compete and where they remain exposed.

B Capital, the investment firm co-founded by Facebook co-founder Eduardo Saverin, now manages more than $12 billion. In 2024 it managed more than $6 billion. The firm closed its latest early-stage vehicle, Ascent Fund III, in July at its $500 million hard cap. The fund was oversubscribed and nearly double the $254 million raised by its predecessor in 2022.

Taken alone, the fund is a modest event in a market where single AI financing rounds now exceed $100 billion. The firm’s structure is the more useful story. B Capital has built separate pools of capital for early-stage, growth and late-stage investing, including a $750 million later-stage fund closed in 2024 that can buy shares directly from companies or from existing holders. That design matters because the venture market of 2026 rewards investors who can stay with winners as they grow, and who can buy into them when early backers want to sell.

How B Capital Built a Fund for Every Stage

Saverin and Raj Ganguly founded B Capital in 2015. They serve as co-chief executives, with venture investor Howard Morgan as chair. The firm has nine offices across the United States and Asia and a strategic partnership with Boston Consulting Group, which gives portfolio companies access to the consultancy’s industry expertise.

The firm’s fund families divide the work by stage:

• Ascent funds invest at seed, Series A and Series B. Ascent Fund III targets healthcare, enterprise software, energy and what the firm calls frontier technology. It has backed more than 20 companies, including humanoid robotics developer Apptronik.
• Growth funds invest in expanding companies. The third growth fund series closed at $2.1 billion in January 2023.
• Opportunities funds invest in later-stage companies. Opportunities Fund II, closed at $750 million in March 2024, was nearly double the size of its predecessor. Most of its capital was set aside for follow-on investments in existing portfolio companies. Its first deal, in June 2023, was a secondary purchase of shares in contract-management software company Icertis.

The firm’s wider portfolio includes AI search company Perplexity, brain-computer interface developer Precision Neuroscience and geothermal power company Fervo Energy. In 2026 it also appointed a general partner and chief AI officer to lead its AI investment strategy.

A Venture Market Concentrated at the Top

B Capital’s model operates in an unusually lopsided market. In the first five months of 2026, four financing rounds raised by OpenAI, Anthropic and xAI totaled $237 billion. That was 86.4% of all U.S. venture-growth deal value over the period.

Fundraising shows the same pattern. U.S. venture funds closed about $62.4 billion through May, putting 2026 on pace for its third-highest year on record. Yet five firms took 73.1% of the commitments closed in the first quarter.

This creates a difficult position for mid-sized managers. The largest firms can write multi-billion-dollar checks into the few companies attracting most of the capital. Small seed funds can survive on high deal volume and small check sizes. Firms in the middle must show investors a clear reason to exist. B Capital’s answer is continuity: it can back a company early and keep investing at every later stage, rather than handing the relationship to a larger investor.

Secondaries Have Become the Late-Stage Market

The second shift in the market favors the type of fund B Capital raised in 2024. U.S. venture secondary trading, in which investors buy existing shares rather than new ones, reached an annualized value of $112.2 billion in the first quarter of 2026. For the first time, it exceeded the value of public listings.

Pricing has also recovered. Secondary deals in 2024 traded at a median 17% discount to the most recent funding round. In 2026, they have traded at par. Companies are holding tender offers far more often, letting employees and early investors sell shares without an IPO.

For a late-stage fund that can buy secondary shares, this has two effects. It widens the range of companies the fund can enter, because early investors in strong companies are increasingly willing to sell. But it also removes the discount that made secondary purchases attractive in 2023 and 2024. A fund that bought shares at a discount in 2024, as Opportunities Fund II was designed to do, entered at better prices than buyers can find today.

Trading is also concentrated. The 20 most-traded companies accounted for 81.1% of secondary trading value in the first quarter, and the top five for 44.6%. Investors who are not already in those names will find secondary entry expensive and competitive.

What the Model Does and Does Not Prove

B Capital’s growth in assets and its oversubscribed early-stage fund suggest that investors are willing to back its platform. That is a meaningful signal in a market where most new commitments go to a few firms.

The evidence has limits. Assets under management can rise because portfolio valuations rise, not only because of new commitments, and the firm does not publish fund-level returns. A multi-stage structure also concentrates risk. When one firm backs the same company across several funds, a single failure hurts several pools of capital, and investors in later funds may be asked to support earlier bets. Investors should judge the model on realized returns from exits, not on fund sizes or valuations.

Why This Matters for Business Leaders

For founders, multi-stage investors offer continuity of capital and fewer fundraising cycles, but at a cost. One investor holding a large position across several rounds can gain significant influence over pricing, governance and the timing of an exit.

For corporate leaders, B Capital’s partnership with Boston Consulting Group is a model of how industry expertise can be offered to startups alongside capital. Companies running their own venture arms face direct competition from investors who can offer similar support.

For institutional investors and family offices, the shift from discounted to par pricing in secondaries means the easy gains of 2023 and 2024 are gone. Manager selection now matters more than access.

Executive Takeaways

What changed: B Capital has doubled its assets to more than $12 billion since 2024, and its newest early-stage fund closed oversubscribed at $500 million.

Why it matters: In a market concentrated in a few AI companies, mid-sized firms that can invest at every stage and buy secondary shares have a clearer case for raising capital.

What leaders should do next: Founders should weigh the governance influence of investors who participate across many rounds. Investors should assess multi-stage managers on realized exits, not paper valuations.

Over the next 12 to 24 months, the key test for B Capital and similar firms will be liquidity. Expected IPOs of the largest AI companies could free up capital across the market, or they could pull more of it toward the same few names. Watch whether secondary prices stay at par and whether multi-stage managers can show cash returned to investors. The main uncertainty is whether the current venture cycle produces broad returns or rewards only those who own the handful of companies at its center.
