We are turning every corner of the world into a social fitness community.

We are turning every corner of the world into a social fitness community. Since COVID reshaped how we stay active, grassroots fitness movements - run clubs, sports leagues, and community-led workouts - have been popping up everywhere. SweatPals is the marketplace built just for them: think of us as the “Airbnb for fitness,” empowering anyone to create, host, and monetize their own fitness community. For members to discover and join communities most suited to them. Over the past 12 months, we’ve grown to 3,000+ hosts and 200,000 members, reaching $10M in annualized GMV this year - a 14x YoY growth. We believe the future of fitness isn’t locked in studios, but rather fueled by decentralized, community community-driven experiences.

Swif.ai

Swif.ai: multi-OS device compliance & security with Shadow IT/AI…

Swif.ai is a real-time device compliance and security platform that keeps every Mac, Windows, and Linux endpoint secure and audit-ready. Our lightweight agent enforces policies (encryption, patching, app controls) as people work, auto-remediates drift, and streams audit evidence to tools like Vanta and Drata. Unlike legacy MDM or “after-the-fact” compliance software, Swif.ai delivers enforcement—not just reports—plus device-level Shadow IT/AI governance to detect and block risky or unauthorized SaaS and LLM tools. Enterprises choose Swif.ai for true multi-OS coverage in a single pane of glass, one-click remediation, and fast time-to-value via silent installers and native integrations with Okta, Microsoft Entra ID, and Google Workspace (conditional access by device posture). The result is fewer tools to manage, shorter audits, and stronger security with lower operational burden. Swif.ai is SOC 2 Type II. Our near-term roadmap adds Safe-AI controls for regulated industries, AI-agent monitoring, and integrated vulnerability detection with one-click fixes—expanding our lead as the enforcement layer for endpoint compliance and AI security.

SwiftSku

Management and analytics software for convenience stores

SwiftSku connects the $650B convenience store industry with management and analytics. SwiftSku’s app connects to point of sales at convenience stores in real time, enabling owners to remotely manage and monitor their stores. We take the guesswork out of running a convenience store with predictive analytics, dashboards, and reports. SwiftSku's CEO, Mit Patel, grew up managing the inventory, pricebook, and reporting of his family’s convenience stores, and, when vendors would come by, he’d bridge the language barrier as a translator. More than 85% of independent convenience stores are owned by Indian families like Mit’s. Solving convenience store owners' pains of today leads to SwiftSku's greater vision of optimizing the supply chain, facilitating a retailer agnostic consumer to brand relationship, and providing real time insights to brands and retailers.

Data for LLMs through Competition

Sylvian creates expert data for LLMs through competitions. LLMs continue to need lots of expert data. Unfortunately, existing data vendors like Scale or Mercor are not motivating the best experts through part-time pay. Competitions are more intrinsic motivators, and naturally incentivize high quality data. Sylvian creates expert data for LLMs through competitions, starting with tool use data (e.g. Excel, VSCode). We already have 4,500+ experts, from IMO Golds to MIT/Stanford PhDs to full time QRs at Point72, producing data at 1B tokens/week!

We provide a novel approach to care in these diseases, centering a patient and caregiver around a coordinator who quarterbacks patients through our full Multi-Disciplinary Care Resources to local aid, PT/OT and home health support. When you leave our clinic, it's not with a handful of paper referrals, but with our coordinators helping you book and find the best physicians, DME, trials, and even cheapest prescriptions. We are devoted to helping patients, from guidance on care and insurance to providing the full spectrum of investigational and clinical testing to improve outcomes. Synapticure was built by leading patient and caregiver advocates alongside leading clinicians, biotech executives and telemedicine executives to bring the neurodegenerative disease care and treatment experience into the 21st century, and is backed by the leading Venture funds and Angel investors in the remote health and life sciences space.
