B Capital is a global multi-stage venture investment firm founded in2015, supporting early-stage through later-growth companies in technology and AI, healthcare, energy and resilience. Its current brand/domain b.capital and older B Capital Group/bcapgroup.com refer to this retained manager. The primary May29,2026 SEC FormADV identifies B Capital Group Management, L.P., CRD287986 / exempt-reporting-adviser file802-110185; the April6,2026 own privacy policy independently identifies that same legal website operator. It is distinct from Boston Consulting Group, Bain Capital, BDC Capital and unrelated B Capital Fund namesakes. Its headquarters are in San Francisco, with a Singapore regional headquarters and other published offices across the Americas and Asia. The own directory publishes92 unique team members and two additionally scoped external BCG advisers, Rich Lesser and Vikas Taneja. All94 named affiliations are recorded with substantive primary biographies and genuine portraits. Howard Morgan is co-founder, chair and general partner; Eduardo Saverin and Raj Ganguly are co-founders and co-CEOs. BCG advisers are explicitly not B Capital partners or employees, do not provide investment advice or participate in fund decisions, and do not manage the firm. Karen Page’s own directory says Board Advisor while her linked biography describes General Partner and Board Partner; both primary scopes are retained. Three unrelated same-name people in semiconductor science, regulatory affairs and biotech legal work remain separate from the B Capital AI/finance professionals. Existing shared portraits, biography facts, external roles and personal investments are preserved. The current adviser filing discloses19 separately named Cayman private-fund vehicles across Ascent, global growth, China, healthcare, opportunities, resilience, Mesa and co-investment strategies. Portfolio gross asset values and the firm’s more-thanUSD12B AUM are not fundraising closes or new company cash. The original July19,2022 announcement rounded the AscentII close to250M; the issuer’s July6,2026 AscentIII release reports the predecessor’s completed254M commitments, so the latter qualified figure is recorded for the same AscentII vehicle, not another close. AscentIII’s actual final close was USD500M on July6,2026. OpportunitiesII closed750M on March19,2024. The January19,2023 GrowthIII series2.1B close includes related companion funds; no2.1B amount is assigned to one individual vehicle or repeated across companions. HealthcareI closed by March1,2023, but the over500M healthcare allocation combines that vehicle with GrowthIII and is not an isolated HealthcareI corpus. Other exact vehicle closing amounts/days remain qualified unless directly proven. The firm’s actual investments span AI infrastructure and applications, precision neuroscience and brain-computer interfaces, AI-enabled drug discovery, digital neurodegenerative care and advanced healthcare. Existing institutional financial records are preserved. Synapticure’s own November19,2024 release expressly names B Capital as lead of its25M SeriesA; its existing round18022/participation38018 is handled by the company owner with no duplicate new check. Exact legal subscribing fund and B Capital’s individual ticket are unpublished. Other sparse relevant portfolio profiles remain queued for identity and financing audits. The original founders’ February8,2018 primary announcement confirms the actual360M inaugural flagship fund finalclose. A founder’s August6,2020 article confirms the secondfundclosed at a rounded820M; the exact unrounded total and closingday remain explicitly qualified rather than inferred from secondary822M reporting.

Its current strategy spans precision neuroscience, life-sciences platforms, aerospace, digital deep technology and climate. It invests at pre-seed, seed and SeriesA and selectively follows companies into later stages. Neuroscience work spans neurodegeneration, psychiatry, neurotechnology, devices and diagnostics, while life-sciences platforms include computational biology and technologies for discovering, developing and delivering medicines. The official roster publishes nine investment and operations professionals plus seven external scientific advisory board members; these advisers provide scientific evaluation rather than acting as operating employees or personal investment counterparties. March20,2026 regulator filings distinguish Dolby Family Ventures LLC, CRD313994/SEC802-122066, from affiliated Dolby Family Capital Management LLC, CRD313971/SEC802-122061. Eight disclosed legal fund vehicles across the two advisers are individually qualified; regulatory assets, gross fund assets and the Dolby family philanthropy or wealth are not fund-closing capital. The platform expressly states it is unaffiliated with Dolby Laboratories and that company’s capital. Its public portfolio identifies investments with active, IPO and acquired statuses, which are source-qualified snapshots rather than evidence of an undisclosed new round, an individual buyer ticket or unchanged current ownership. Existing imported affiliations absent from its current directory are retained with current appointment unverified rather than treated as newly confirmed staff.

Each cycle culminates in Demo Day, when the startups present to a large audience of investors. About halfway through each cycle the firm holds an event called Angel Day, at which each startup is paired with 2 angel investors, who will meet with them regularly in the weeks leading up to Demo Day. YC and the YC alumni network continue to help founders for the life of their company. Since 2005, YC has funded over 630 startups. SHOW MORE Founded: 2005
