We also build and integrate AI-powered features into mobile, web, SaaS, and business products. But we’re not just here to execute a specification. We work closely with founders, CEOs, and product teams to validate ideas, challenge assumptions, define the right MVP scope, prioritize what actually needs to be built, identify risks, and find the shortest practical path to market. Whether you come to us with an idea, existing UX/UI designs, a detailed specification, or a live product that needs to scale, we can join at the right stage and move it forward. 🔍 Lower-Risk, Transparent Cooperation We know choosing a development partner is a major decision, especially for an early-stage company. That’s why our cooperation model is designed to keep founders in control: 2-week trial period · Post-payment · Weekly sprints · Transparent task & time tracking · Regular demos · Fast team start · 100% code ownership You get a team that thinks beyond individual tasks - considering product, UX, technology, architecture, scalability, risks, budget, and business priorities throughout development. We build lean, launch fast, and stay honest about what your product actually needs. Have an idea or an existing product? Let’s find the smartest way to move it forward.

Entalogics is an AI-augmented software development and cybersecurity solutions company with 600+ delivered projects for clients across North America, Europe, Middle East, and Asia-Pacific. We cover all major business timezones and work exclusively in English. We commit to fixed-price contracts. No open-ended retainers, no estimate creep. Before any build starts, we scope it precisely: delivery timeline, budget, and feature set are agreed and locked. This is our default engagement model, not a premium option. Every engineer is senior-level. This is a hiring policy, not a sales pitch. No juniors on client projects. The engineer in your scoping call is the engineer building your product. AI is our operating model, not an add-on. Every engineer works inside AI-augmented workflows across the full lifecycle. AI handles boilerplate, testing, and documentation. Engineers handle architecture, business logic, security, and code review. Production-grade output in weeks, not months. Security is built in, not bolted on. Every product we ship goes through threat modeling, secure code review, and pre-launch testing as standard — not as an upsell. We also offer standalone cybersecurity solutions: security audits, penetration testing, and hardening for products built elsewhere. What We Build: * Complex SaaS platforms * AI-powered products (LLM integration, agents, automation) * Custom Chromium browsers (fewer than 10 teams globally with this expertise) * Web apps (React, Next.js, Node, Django, Laravel) * Mobile apps (Flutter, React Native, native iOS/Android) * Desktop applications (Electron, Tauri) * Cybersecurity solutions (audits, penetration testing, secure architecture) * UI/UX design, cloud, and DevOps We rescue projects that have gone wrong. Products damaged by poor engineering and products built with no-code or vibe-coding tools that outgrew what those tools can support. We stabilize, refactor, secure, and bring them to production-grade under a fixed-price scope. Our team augmentation goes further than staffing. Every engineer we place works inside AI-augmented workflows by default. You are not getting extra hands. You are getting engineers who deliver 2-3x the output with documented, maintainable code. Recognized by Clutch, GoodFirms, Upwork and TopDevelopers globally with 5.0 ratings. The scope changes. The standard doesn't.

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

Code is no longer the bottleneck. Strategy, speed, and the right architecture are. How you engineer your product defines how far it can go. Founded by engineers in 2000, Anadea brings a builder's mindset to every project. The company operates as a one-stop-shop for product ideation, creation, and maintenance, guided by direct involvement in clients' success. Anadea is trusted by lasting partnerships. For over a decade, they have helped platforms like Visdeal (a top sector performer) and StreetEasy (part of Zillow Group). Today, StreetEasy is New York's leading real estate service, attracting over 180 million visits annually. Transparency is a standard practice for Anadea, and verified client references are readily available as part of the due diligence process. AI-ACCELERATED ENGINEERING Launch a new product and get to market 5x faster with AI-accelerated engineering AI-accelerated development lets us ship your product in weeks instead of months. But speed means nothing if the product can't scale, so we build every MVP on architecture that's ready for growth. It all starts with a two-week Discovery sprint at a fixed price. You walk away with an architecture, a roadmap and a clear estimate before committing to anything bigger. LONG-TERM PARTNERSHIP Get a strategic engineering partner for long-term product growth For 12 years, StreetEasy has trusted us as its engineering partner. 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. We take ownership of technical direction and help established teams move faster with confidence. OPERATIONAL AI Automate operations and multiply team capacity with AI For a US law firm, we built AI that processes thousands of pages of medical records in minutes instead of a week. 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 figure that out with you and handle the entire technical side.

ANML is a senior-led design agency for B2B, AI, and emerging technology companies. Founded in 2012, we design websites, digital products, design systems, and brand systems — with the brand and the product shipping as one system rather than as separate projects. Our work concentrates in three places: enterprise software and SaaS platforms where complex workflows have to become usable; AI products where the interaction patterns don't exist yet; and connected-device and IoT experiences where the companion app is the product. We do the same work for consumer brands, where the craft is identical and the constraints differ. Senior designers do the work end to end. Strategy doesn't get handed to juniors after the pitch. Services: digital product design, enterprise and B2B UX/UI, AI and emerging technology interfaces, IoT and connected devices, design systems, web design and front-end development, brand strategy and identity.

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. Our Tech Stack: We work with modern, proven technologies across the full stack: Frontend: React, Vue.js, Angular, Next.js, Nuxt.js Backend: Node.js, NestJS, .NET, PHP, Laravel, GraphQL Mobile: React Native, Swift, Kotlin Cloud & DevOps: AWS, Azure, GCP, Kubernetes AI/ML: Python-based frameworks, custom model integration CMS: Storyblok, Prismic, Strapi What Makes Us Different: Three things define how Brights operates: 1. People first. We hire for depth — our engineers understand systems at a foundational level and can solve hard problems, not just complete tasks. 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. We are also proud to be a tech partner of the Serhiy Prytula Charity Foundation, supporting Ukraine's defense and civilian relief efforts.
