AI-summarised brief · reviewed before publication

New York‑based Vest Labs, backed by Portal Ventures, raised $13 million in a seed round to launch a proprietary trading firm that lets qualified traders use company capital to trade perpetual futures around the clock. The firm shares up to 80 % of traders’ profits, aligning its earnings with user success rather than charging simulation fees. Cofounded by University of Pennsylvania dropouts Justin Ma, Rikuya Takatsu, and Maximilian Tsiang, Vest plans to build a mobile app, expand its 22‑person team, and broaden asset offerings. The round included investors such as Citadel Securities, BlackRock, and KKR executives.

💡 Why It Matters

· Vest’s profit‑sharing model challenges the prevailing fee‑based structure of retail prop trading, potentially democratizing access and incentivizing genuine trader performance.
· Its rapid growth signals a shift toward more trader‑aligned business practices in a sector projected to hit $850 million in revenue by 2026.

While VCs crowd into San Francisco, Endeavor Catalyst raises $320M for founders…

Endeavor Catalyst closed its fifth fund with $320 million in commitments, raising its total assets under management to over $850 million. The New York‑based nonprofit’s venture arm, which focuses on founders “elsewhere” than Silicon Valley, will deploy the capital into 40‑50 deals per year, targeting up to 150 companies overall. Managed by Allen Taylor and Jackie Carmel, the fund backs entrepreneurs who first join Endeavor’s global network of more than 3,100 founders in 50 countries; only 88 of 10,000 screened candidates were accepted last year. Investments range from $1‑3 million and cannot exceed 10 % of a round, typically following a lead investor’s $5 million minimum. The firm’s portfolio includes AI voice startup ElevenLabs ($22 billion valuation), Italy’s Bending Spoons ($26 billion), and Replit ($9 billion). Half of the fund’s profits flow back to Endeavor to support future founders.

💡 By channeling capital to under‑represented regions, the fund challenges the Silicon Valley‑centric financing model and creates a self‑reinforcing pipeline for global entrepreneurship.

Quanfluence Raises $10 Million for Photonic Quantum Computer

Quanfluence, a photonic‑based quantum computing startup, announced a $10 million financing round led by Indian venture firm Chiratae Ventures. The company aims to overcome the interaction‑control challenge of photons by integrating custom hardware and software into a unified architecture. Its roadmap targets a four‑qubit prototype by 2027 and a roughly 100‑qubit system by 2029, emphasizing scalability over sheer qubit count. Quanfluence argues that photonic approaches can sidestep some engineering limits of superconducting and trapped‑ion platforms, potentially enabling larger quantum processors in more flexible operating environments. The funding will support development of the early processor, expand the engineering team, and accelerate the transition from laboratory demonstrations to commercial‑grade quantum hardware.

💡 By securing capital for a photonic architecture, Quanfluence positions itself to break the scalability bottleneck that hampers most quantum hardware contenders.

Robot data startup Mecka AI nabs $60M from Sequoia

Mecka AI, a robotics‑data startup founded in 2024, announced a $60 million Series B financing round led by Sequoia Capital. The round also included participation from Nvidia, Microsoft’s venture fund M12 and other investors. Mecka builds a platform that pays participants to record everyday motions—such as making coffee or repairing a car—while wearing body sensors and using smartphones, creating labeled datasets for training humanoid and industrial robots. The company aims to replicate the role of data‑labeling firms like Scale AI in the large‑language‑model space, but for robot‑perception and control. Industry observers had previously reported that Mecka was approaching a new round at a $500 million valuation. Competitors such as XDOF and extensions of LLM‑focused data platforms are also targeting robot‑training data global markets.

💡 Commercializing large‑scale human motion data could dramatically shorten the time needed to teach robots complex, real‑world tasks, moving automation out of labs and into daily life.

Mistral Large 4 Launch Seeks to Keep Europe in the AI Race

French startup Mistral AI unveiled its latest large multimodal model, ML4, a 1‑trillion‑parameter system with 49 billion active parameters. The company claims the model matches the strongest open‑source offerings worldwide and exceeds other open‑weight models from the US and Europe on enterprise tasks such as cybersecurity, finance and law, while also surpassing closed models in visual‑grounding benchmarks. ML4 is currently accessible via guarded endpoints, with full weight release promised within three weeks after safety testing. Mistral raised a record‑breaking funding round and highlighted strategic partnerships with industry leaders like Samsung, positioning the effort as a “third way” in AI that bridges the divide between open Chinese initiatives and closed US giants. President Emmanuel Macron endorsed the launch on X, emphasizing Europe’s ambition to become a global AI power.

💡 By delivering a high‑performing, soon‑to‑be‑open model, Europe gains a credible alternative to US‑dominated closed AI systems, reshaping geopolitical tech balances.

Healthleap raises $38M for its AI that flags hospital patients who may…

Healthleap, an AI startup, announced a $38 million seed and Series A raise—$8 million co‑led by Sequoia Capital and First Round, and $30 million led by Hummingbird Ventures. Founded in 2022 by siblings Jemima and Josiah Meyer, the company pivoted from a nutrition‑tool to a platform that scans electronic health records, extracting structured data and clinicians’ free‑text notes to flag in‑patients at risk for conditions such as malnutrition, delirium, aspiration pneumonia, pressure ulcers and heart‑failure readmission. The system now runs in more than 50 hospitals, including Penn Medicine, Cedars‑Sinai and Emory, and reportedly generated over ten‑fold revenue growth, delivering a minimum 5× ROI for clients. Healthleap will use the capital to expand engineering, sales and its condition‑coverage roadmap, targeting 40 illnesses and outpatient settings.

💡 By turning hidden clinical cues into actionable alerts, Healthleap gives hospitals a proven tool to cut stays and boost reimbursements, turning AI insight directly into measurable financial returns.
