Valletta.Software is a Malta-based software engineering company with 700+ delivered projects for clients across Europe, Israel, and North America. We operate under EU jurisdiction and work exclusively in English. 1) We build forward-deployed engineering teams. Our engineers embed into your organization, work with your stakeholders, translate ambiguous business problems into working software, and stay accountable through production. Every engineer we place is trained in AI-assisted workflows, prompt engineering, and AI-agent orchestration, ships 2-3x faster than a conventional developer, and leaves documented, maintainable code. The hard part of AI adoption is turning spend into measurable ROI. We run discovery on your process, take one task bounded by scope and time with agreed metrics, deliver in weeks, then scale the team around what worked. 2) We commit to fixed-price contracts. Timeline, budget, and feature set are agreed and locked before any build starts. This is our default engagement model. Team augmentation is available where you own the process and need FDE capability inside it. 3) Our DevOps and SRE practice provides 24/7 monitoring and on-call coverage on agreed projects. Engineers across time zones handle alerting and incident response, backed by Kubernetes, infrastructure as code, CI/CD pipelines, Prometheus, Grafana, Datadog, and cost optimization on AWS, Azure, GCP. 4) We rescue projects that have gone wrong: products damaged by poor engineering (broken architecture, critical bugs, no documentation, technical debt) and products built with vibe-coding tools that outgrew them. We stabilize, refactor, and bring them to production grade under fixed price. 5) We connect LLMs (Claude, GPT, local models) to your systems and messaging channels, build long-running agent runtimes, and handle secure deployments. We have hands-on expertise in Claude Code in client work: CI/CD integration, multi-agent development workflows, and code generation with review gates.

Engineering Partner Accountable to the Outcomes
Aimprosoft is a product engineering and AI implementation partner for companies that need technology to produce measurable business outcomes, not just working software. We build custom software platforms, SaaS products, and mobile apps, and we implement AI in production, including LLM integrations, RAG pipelines, intelligent document automation, and conversational assistants, with adoption tracked rather than left to a pilot that never ships. What sets us apart is accountability. We put KPI commitments in writing before Sprint 1, covering targets such as lead time reduction, defect rate, and planning accuracy. Before any AI investment, our AI audit gives clients a GO/NO-GO recommendation grounded in the evidence, not a sales pitch dressed up as a roadmap. In 20 years, we've grown from 3 people to a team of 200+ people, delivered work across 26 industry verticals, and built partnerships with 650 clients in 28 countries, some spanning 16 to 17 years. 72% of clients return for their next major initiative, more than double the industry average, because they get a business partner instead of a resource pool. Core services: - Custom product and platform engineering: web, mobile, cross-platform, cloud, DevOps, and QA - AI in production: LLM and RAG integrations, intelligent document automation, computer vision, NLP, and predictive analytics - AI audit and AI strategy consulting - Legacy system modernization - Embedded, long-term engineering teams and staff augmentation

Our work tends to sit where normal software consulting stops being enough: secure knowledge synthesis, AI-assisted legal and scientific workflows, retail recommendation and 3D spatial commerce, high-throughput genomics pipelines, autonomous energy optimization, AWS GovCloud SaaS modernization, decentralized freight and commerce infrastructure, Solana validator operations, and security testing for advanced cryptographic software. Clients work with Dreamers when they need senior engineers who can reason across product, infrastructure, data, security, and domain research.

Anadea
VerifiedEngineering what comes next

Together, we’ve evolved its platform from a monolith into a system that handles 180 million annual visits and runs 33 times faster. That doesn't happen when you only write code.

For a $10B European private equity fund, we deployed five AI agents that screen 5,000 opportunities in hours. Most companies want automation but don't know where to start.

We are Reliqio — we turn digital products into habits.
Reliqio builds AI-powered B2C products for founders in healthcare and fintech — industries where retention is the business model and a weak release can cost a company its license to operate. We own the work end-to-end: product strategy, design, engineering, and the LTV, retention, and conversion outcomes it produces. Most teams that build for founders ship to the brief and stop there. Reliqio was founded in 2018 to close that gap — to give a non-technical founder a co-founder-level technical team without a multi-year search. The bet was that a smaller team with a real product mindset would outperform a larger team with a delivery mindset. Seven years in, our portfolio is the proof. Today, we are a distributed team of about 20 across Europe and beyond. Three metrics shape every decision we make: LTV, retention, and user conversion. Every architectural call, every interface, every line of code connects back to one of them. If it doesn't, it doesn't ship. Our practice combines product engineering with behavioral science and AI-native delivery. Behavioral science, because retention is designed into a product before the first wireframe is drawn. AI-native, because what a small team can ship has changed, and our delivery model is built around the change rather than bolted onto it. Founders come to us when they need a partner who will share the weight of the decision, the ambiguity, and the result.

Over 15 years, we've grown into a team of 120+ specialists and delivered 300+ projects for clients in 30+ countries. We hold ISO/IEC 27001 certification, have earned 24 industry awards and recognitions, and maintain a 4.9/5 rating on Clutch — but what we're most proud of is simpler: 70–80% of our clients stay with us well beyond the initial engagement. What We Do: We provide end-to-end software development services across the full product lifecycle: from early-stage idea validation and MVP development to scaling complex enterprise platforms. Our core services include: - Custom web and mobile app development - UI/UX design and product design - AI/ML integration and custom AI development - Cloud engineering and DevOps - SaaS development and consulting - Dedicated development teams and staff augmentation - UX audit and product modernization We work across industries including fintech, insurtech, logistics, edtech, e-commerce, healthcare, real estate, and travel & hospitality. How We Work: At Brights, we act as co-creators — not just executors. Our specialists bring ideas, initiative, and ownership to every engagement. We focus on understanding the business goals behind every project, not just the technical requirements. That means our teams actively contribute to product decisions, suggest improvements, and help clients think strategically about their technology. We offer flexible engagement models to fit different project stages and business needs: Time & Materials, Dedicated Team, Fixed Cost, and milestone-based billing.

And internally, we invest in each other just as much as we invest in client projects. Strong teams build strong products. 2. High standards, always. We are selective in hiring and demanding in delivery. Our specialists are celebrated for going beyond — because we genuinely believe that transcending limits is what separates good software from great software. 3. Co-creators, not doers. Our average client relationship lasts over three years. That's not an accident — it's the result of treating every engagement as a long-term partnership, not a transaction. Trusted by Leading Brands: We've collaborated with globally recognized organizations including Mastercard, Microsoft, Pepsi, and Danone, as well as Fortune 500 companies such as Coca-Cola, McDonald's, and Kimberly-Clark.
