- Baseten
Participated · Series F · Jun 2026
Baseten provides software and multi-cloud compute infrastructure to help companies optimize, customize, and serve open-source AI models, handling inference workloads and latency optimization. The company positions itself as enabling enterprises to deploy open-source models efficiently, competing with closed-source alternatives by reducing costs; at least one customer reported up to a 30% cost reduction. Key customers include Cursor, Mercor, and OpenEvidence. Baseten’s annualized revenue run rate has surged from roughly $200 million to about $600 million. The company has rapidly increased its valuation in 2025–2026 through multiple financing rounds, most recently reaching as high as $13 billion in the current transaction.
- Capchase
Led · Equity · May 2026
Capchase provides a vendor financing platform and acts as a lender to help enterprise technology companies close more deals by offering instant financing to buyers. Its platform embeds underwriting, origination, and deal management directly into sales workflows and uses AI agents to generate loan proposals and documents. The company’s Agentic Lending Coordinator collects quotes, POs, emails, and other documents and converts them into executable loan packages while managing multi-party collaboration through signing. Capchase reports that since beta launch customers have condensed an 8-hour process into a 60-second automated workflow. The recent financing will be used to scale its embedded financing infrastructure globally and to roll out more AI-enabled features. The company is headquartered in New York City.
- Fractile
Participated · Series B · May 2026
Founded in 2022, Fractile develops chips and systems aimed at dramatically speeding up inference for frontier AI models. The company’s thesis is that time-to-output and inference unit economics—particularly memory bandwidth limits—are the next major bottlenecks as models generate increasingly long outputs. Fractile is working across AI research, chip microarchitecture, and foundry process innovation to reduce inference latency and cost. Its technology targets workloads that can require tens of millions of tokens and seeks to enable new, longer-running AI tasks by making faster inference economically viable. The company is expanding its team and hiring across London, Bristol, San Francisco, and Taipei as it scales development. Financial metrics, customers, and prior funding amounts were not disclosed in the articles.
- Atlas Card
Participated · Series C · Apr 2026
Atlas operates a members-only concierge service and charge card that aims to deliver access to coveted experiences alongside a seamless spending experience. The company announced a $40 million Series C at a $420 million valuation in April 2026. Investors in the round included lead backers Elad Gil and Verified Capital, as well as 01 Advisors, Marathon Management Partners, and others. Legal counsel on the transaction was Wilson Sonsini Goodrich & Rosati, which advised Atlas through a team led by Rob Broderick. The public reporting does not disclose revenue, user counts, or specific go-to-market metrics. The company also did not disclose detailed plans for the proceeds in the coverage.
- Crosby
Led · Series B · Mar 2026
Crosby positions itself as a hybrid AI law firm that speeds contract execution, stating it gets contracts signed 80% faster. The company serves customers including Ramp, Clay, and Rogo and reported negotiating $30M in contracts at launch, growing to over $1 billion within months. Crosby operates with a compact engineering team of about 15 people and is actively hiring across engineering, product, design, legal, and operations. Leadership framed the company as an "applied AI firm" (referred to as Neofirm) and plans to scale talent density following the Series B. The announcement did not disclose revenue figures or a valuation.
