ziggiz is the data platform that enables AI for security, across all your data, at any scale. Security teams cant keep pace with AI deployments and AI-empowered attackers because the data infrastructure they depend on is architecturally broken. A cyber-search world is no longer valid. ziggiz was built to move security from cyber-search to cyber-analytic — handling collection, normalization, enrichment, storage, and routing so your team can stop engineering data and start using it. DARPA-funded at origin, the platform works inside the stack you already run. No rip and replace. Just results. Every source ingested. Every vendor normalized. Every alert enriched with device, identity, and activity context before your team sees it. What that looks like in practice (source: DARPA blog): • 25x more efficient — making security viable at scale • 5x faster data source onboarding vs. industry average • 90% less engineering effort vs. managing your own pipeline • 0% data loss — vs. the industrys 3–6% event drop rate Collect | Store | Analyze | Share. ziggiz builds the semantic layer first — across firewall, identity, endpoint, app logs, fraud, and AI tooling — so every agent, automation, and detection runs on complete, structured, explainable data. Govern every AI tool in your estate, defend against AI-driven threats, and harness AI yourself. Not just alerts. Answers. Built for regulated environments: SOC 2 Type II certified and HIPAA compliant, with FedRAMP, CMMC, NIST AI RMF, and ISO 42001 on the way. Financial services. Pharmaceuticals. Government. And if youre a non-profit in healthcare, well support your mission at cost. Zigguratum, Inc. (d/b/a ziggiz) is a Built on Databricks partner, selected for Databricks inaugural AI Accelerator.

Sapiom is the platform vertical AI companies use to ship, run, and scale AI agents. It removes the infrastructure barriers between a working agent demo and an agent running in production, helping engineering teams operate agents economically, reliably, and with control. Sapiom Router lowers inference costs by matching each call to the most efficient model instead of defaulting to the most expensive one. Two lines to try, no migration. Sapiom Agent Studio takes you from idea to a working agent. Build, test, and inspect locally with the context of your existing codebase, then deploy to production with one command. Sapiom Runtime is the managed infrastructure agents run on. Sandboxes, memory, secrets, and tools built in, with automatic recovery when steps fail and every model and tool call recorded with its cost and outcome. Founded in San Francisco in 2025. Backed by Dragonfly, Accel, Gradient, Coinbase Ventures, Okta Ventures, Menlo Ventures, Anthropic, Array Ventures, Operator Collective, Formus Capital, and VanEck Ventures. Our mission is to unlock the next trillion agents. Start building at sapiom.ai.

Damisa is a regulated B2B cross-border payment, settlement, and treasury infrastructure built for businesses moving capital across borders. Built on regulated stablecoin rails, the infrastructure operates across 70+ currencies spanning Africa, LATAM, MENA, Asia, and Europe, with specialist expertise in emerging and high-growth market corridors. Settlement happens in hours, including weekends, with transparent fees and full visibility from initiation to receipt. Compliance is the foundation. Every transaction runs through full KYB/KYC, AML, Travel Rule compliance, transaction monitoring, and real-time sanctions screening. Damisa has multiple regulatory registrations spanning across multiple jurisdictions. Behind the infrastructure is a founding team with experience in payments, treasury, financial infrastructure, and consulting, with backgrounds spanning Volt, Google, Agoda, Bain, and Bridgepoint. The founders have spent their careers inside the system Damisa is replacing. The mission is to empower the world with access to always-on financial infrastructure.

The latest generation of AI models achieves breakthrough performance by spending vastly more tokens to solve complex problems. Demand is now compounding faster than the infrastructure beneath it can scale. The constraint sits in how tokens are made. Producing a token is not one operation but many, each placing different demands on hardware, yet every AI system in production runs them all on the same general purpose chip. Moving work between chips has always cost too much energy and time for anything else to be viable. That compromise is why the current approach cannot deliver high throughput and high interactivity at low cost, however large the single chip grows, and and why tokens remain scarce and expensive. Continuing AIs advance, and making it available to everyone, requires the datacentre to be rebuilt the way every great factory has been built: as a production line, with specialised machines and fast, cheap movement between them. OLIX is building that production line: the token factory for frontier AI. If you like working on the hardest and most consequential problems, we want you at OLIX. We are hiring across London, Bristol, Austin, Toronto and San Francisco. Check out our careers page at olix.com/careers.

Every generational shift in computing requires a new layer of security infrastructure. In today’s agentic era, Outerlimit provides the world’s first decentralized security and authorization layer designed specifically for securing Agentic AI. Recognizing a fundamental shift in enterprise risk, Outerlimit is extending Zero Trust to the agent action layer, binding identity, authorization, and action into a single operation at the moment of tool execution. Meeting Enterprise customers where they are today, Outerlimit guides organizations from discovery and observability to deterministic enforcement. Partnering with Fortune 500 and FTSE 100 global brands, Outerlimit is backed by leading cybersecurity investors AlbionVC, Evolution Equity Partners, and Crane Venture Partners with offices in London and New York.

Stealth AI Startup is an independent initiative focused on founders building AI companies before public launch. We explore the earliest stages of building an AI startup—from testing an idea and finding collaborators to assembling a team and preparing to launch. Our focus: • Founder experiences and lessons from building in stealth • Emerging AI technologies and startup trends • Perspectives from founders, researchers, engineers and investors • Practical learning for the journey from idea to launch We believe founders can exchange knowledge and build meaningful professional connections while keeping their products and plans confidential. This is the official LinkedIn Page of the Stealth AI Startup initiative. It represents our initiative, rather than the separate companies built by founders who follow it. Following or engaging with this page does not, by itself, establish employment, partnership or endorsement. Follow us for perspectives on building AI companies and updates from our initiative.

Cogna builds AI software for the hardest, highest-stakes work physical industries depend on. Physical industries have never mattered more. They power, move, build and maintain the systems society relies on, while facing ageing assets, rising demand, tighter regulation and the pressure to improve productivity. Yet too much critical work still runs manually, with operating context spread across documents, processes, systems and experienced people. Cogna turns that context into production AI applications that reduce manual work, make hard-won expertise reusable and improve performance where it matters most.

Stealth FinTech Startup

Most payment stacks treat account and wallet payments as passive methods.
We don’t. Nopan is a specialized PSP built by former large-merchant payment leaders, designed to turn account and wallet payments into measurable revenue drivers. Because performance doesn’t come from technology alone. It comes from how payments are designed, tested, and optimized in real-world environments.
