VerifiedEngineering what comes next
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.

Entalogics
VerifiedTop-tier AI-Augmented Software Development & Cybersecurity Company
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.

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.

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.
