SurveyJS is a set of four open-source JavaScript libraries that offer the benefits of a tailor-made in-house survey application, while considerably reducing the time and resources needed to deploy the system. These libraries are independent of specific server code or database requirements and seamlessly integrate with popular JavaScript frameworks, including React, Angular, Vue.js, jQuery, Knockout, and more. They are designed to communicate with any server that can handle JSON requests, ensuring compatibility with various server architectures and databases. The product family is composed of: - An open-source MIT-licensed rendering library that renders dynamic JSON-based forms in your web application, and collects responses. - A self-hosted drag & drop form builder that features an integrated CSS-based theme editor and a GUI for conditional rules. It automatically generates JSON definitions (schemas) of your forms in real time. - PDF Generator, a library that renders SurveyJS surveys and forms as PDF files in a browser; - The Dashboard library that allows you to simplify survey data analysis with interactive and customizable charts and tables.

JOpt.TourOptimizer is an enterprise optimization engine for route planning, scheduling, and resource allocation across logistics, transportation, dispatch, and field service operations. It is built for organizations that need to solve complex planning problems under real-world business constraints rather than simple consumer-grade route calculation. The platform supports vehicle routing and scheduling scenarios such as VRP, CVRP, VRPTW, pickup and delivery, multi-depot planning, heterogeneous fleets, and workforce scheduling. JOpt.TourOptimizer can model time windows, working hours, visit durations, capacities, skills and expertise levels, territories, zone governance, overnight stays, alternate destinations, and custom business rules. This makes it suitable for production deployments where feasibility, transparency, and operational reliability matter. It is designed to generate practical plans that help teams balance travel time, service commitments, workload distribution, and operational cost in demanding enterprise environments. The solution is available both as an embedded Java SDK and as a Docker-based REST API with OpenAPI and Swagger support. This allows software vendors, enterprise developers, and system integrators to embed advanced optimization into TMS, ERP, CRM, WMS, dispatch systems, customer platforms, and field service applications. With support for scalable integration and modern service architectures, JOpt.TourOptimizer helps organizations improve planning efficiency, service quality, SLA compliance, transparency, and operational resilience at scale. It also supports enterprise integration strategies that require reproducible optimization runs, structured outputs, and flexible deployment models.

OpenMetal reimagines Infrastructure as a Service (IaaS) by delivering high-performance, OpenStack-powered private clouds, bare metal dedicated servers, and GPU clusters. Our platform is designed to scale with any organization, from agile startups to established enterprises. Historically, the power of a private cloud was gated by massive capital requirements and technical complexity. Because managing dedicated infrastructure demands specialized expertise and heavy hardware investment, it remained an exclusive tool for the world's largest corporations. OpenMetal changes that dynamic. We provide the sovereignty and agility of a private environment without the traditional burdens of manual construction or maintenance. -Rapid Deployment: Go live in as little as 45 seconds. -Full Control: Manage your own dedicated infrastructure immediately. -Accessibility: High-level cloud technology tailored for budgets of all sizes. We view open source not just as a software model, but as a global engine for progress. By fostering international collaboration and collective innovation, open source empowers individuals to build upon existing successes to create something better for everyone. Our goal is to streamline the path to open-source adoption. By removing technical friction, we enable teams and individuals to focus on what matters: contributing to the community and driving the future of IT.

Dragonfly serves as a seamless substitute for Redis, offering enhanced performance while reducing costs. It is specifically engineered to harness the capabilities of contemporary cloud infrastructure, catering to the data requirements of today’s applications, thereby liberating developers from the constraints posed by conventional in-memory data solutions. Legacy software cannot fully exploit the advantages of modern cloud technology. With its optimization for cloud environments, Dragonfly achieves an impressive 25 times more throughput and reduces snapshotting latency by 12 times compared to older in-memory data solutions like Redis, making it easier to provide the immediate responses that users demand. The traditional single-threaded architecture of Redis leads to high expenses when scaling workloads. In contrast, Dragonfly is significantly more efficient in both computation and memory usage, potentially reducing infrastructure expenses by up to 80%. Initially, Dragonfly scales vertically, only transitioning to clustering when absolutely necessary at a very high scale, which simplifies the operational framework and enhances system reliability. Consequently, developers can focus more on innovation rather than infrastructure management.

AlsoThere: A Real-World Governance Plug-In for Global Expansion. We built AlsoThere to solve a massive headache for SaaS founders and tech builders: cross-border bureaucracy. Selling internationally forces you into two terrible legacy options: blow 6-12 months and massive capital (CAPEX) setting up a traditional subsidiary, or hand your product to IT resellers who hijack customer relationships. Our innovation unbundles commercial capability (selling, invoicing, collections) from the legal burden of incorporation. Think of AlsoThere as an "Infrastructure-as-a-Service" for global expansion. We built a unified operational platform with active nodes across 43 countries in the US, EU, and LATAM. Instead of managing fragmented entities, you plug into our centralized backbone. Within 48 hours, your company can legally sell, sign contracts, and issue tax-compliant local invoices in local currencies. We integrate into your commercial flow via a Representation Agreement, an Operational Governance "Plug-In". If you land an enterprise client in Colombia or Spain, you don't need a legal team for local tax rules. We act as your authorized agent, ensuring compliance with all tax, legal, and regulatory frameworks. You convert high-risk expansion into a predictable operational expense (OPEX) while retaining 100% ownership of your sales cycle. We advocate the "Tech Partner 3.0" framework, allowing you to sell directly anywhere. An international B2B transaction has four components: contract, invoicing, payment collection, and compliance. We act as your specialized transactional layer and handle these 4 steps completely. Backed by eSource Capital Group’s 20-year track record, we’ve processed over US$250M for third parties. You focus on selling; we'll handle the borders.
