Conversive is the Demand Conversion Platform that captures, qualifies, converts and nurtures customer demand — across every channel, every team, every stage of the relationship. Every conversation is powered by the Conversational Harness — the intelligence layer that connects customer data, memory, business knowledge, workflows, policies and conversation history into one shared context. Unlike phone systems, chatbots or CRMs that only communicate or store information, Conversive understands, remembers and acts — guiding each customer according to their history, your offerings, your policies and your rules.

At SiegePal, we're building an AI-powered cybersecurity platform that helps businesses identify vulnerabilities, understand security risks, and protect their applications and cloud infrastructure more efficiently. Our platform brings together specialized AI agents that work alongside security professionals to automate complex cybersecurity tasks, from reconnaissance and vulnerability scanning to penetration testing, threat analysis, and compliance reporting. By integrating existing security tools with large language models (LLMs), we aim to reduce repetitive manual work and make advanced security capabilities more accessible. **The hard problems we're solving:** - **AI agent orchestration:** Building a system where multiple specialized AI agents can collaborate, share context, and execute complex security workflows reliably. - **Security automation:** Turning fragmented security tools and manual processes into coordinated workflows that identify, prioritize, and help remediate vulnerabilities. - **Cloud security at scale:** Integrating with AWS, Azure, and Google Cloud to assess infrastructure, detect misconfigurations, and manage security risks across complex environments. - **Safe AI execution:** Giving AI agents the ability to interact with real systems while maintaining strict permissions, isolation, auditability, and human oversight. - **Actionable security intelligence:** Transforming large volumes of technical findings into clear recommendations that engineering teams can act on. Alongside our platform development, we deliver cybersecurity and AI engineering services for businesses operating in cloud and regulated environments. We're a small, engineering-driven team working at the intersection of cybersecurity, artificial intelligence, and cloud infrastructure. Our developers tackle real technical challenges, experiment with emerging technologies, and have the opportunity to shape a product from its early stages.

We’re a hypergrowth AI startup backed by top-tier VC firms. We’ve created a new paradigm for enterprise artificial intelligence with a breakthrough technology called Organizational Memory (OM1). It’s fundamentally reshaping how people do work. Unlike any other AI product, OM1 builds “a brain” for companies–knows what’s happening in real time across the whole business, and has all the output capabilities of a human employee. Roles like Product, Engineering, G2M, and Management will never be the same. And while we’re starting by selling our technology to other software businesses, we have the ability to serve hundreds of different industries. We're not just building another productivity tool. We're ushering in a fundamental revolution in how humans do work. With proven product-market fit, rapid YoY ARR growth, and household-name customers, we’re expanding our team to dominate what will be a $10T+ industry. And we’re only just getting started.

Mercata is a secure AI sidekick for fundamental investors. We turn unstructured internal and external data into a real-time, queryable research environment so analysts and portfolio managers can move faster, ask better questions, and make more confident decisions. With Mercata, research teams ask layered, high-context questions that traverse companies, people, and time, and get traceable, source-linked answers. The system scans filings, press releases, and news in real time and surfaces what is new and factual, highlighting potential impacts on existing investment theses. It frees analysts from data mining so they can produce unique insights and apply their judgment. Teams can integrate proprietary research into Mercata’s dynamic intelligence layer, creating a unified system of record for faster recall, deeper analysis, and clear decision trails.
