Entalogics

Verified

Top-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.

EltexSoft

Verified

AI-first engineering studio. The seniors who scope your build are the ones who ship it.

EltexSoft is an AI-first software engineering studio. Since 2015 we've built and maintained web, mobile, and AI products for founders and established companies, and we run every engagement with senior engineers who stay on the account for years rather than rotating off after kickoff. We're 35 to 50 people across Los Angeles, New York, and Kyiv. The engineer who scopes your project is the one who ships it, so context compounds instead of resetting each quarter. That continuity is why our client relationships are measured in years. What we build: ✓ Full-stack web (Laravel, Python, React, Node) ✓ Native mobile (iOS and Android) ✓ AI and generative-AI features, in production ✓ QA, DevOps, and CI/CD ✓ Senior staff augmentation for teams that need capacity fast Where we work: real estate, healthcare, sports, food delivery, e-commerce, fintech, and education, from platforms under heavy production load to consumer apps with millions of installs. We've been AI-first since 2021, when we started with AI-assisted test coverage because quality is how we compete. Today AI runs through every workflow: research, architecture, code review, testing, and shipping. Rated 5.0 on Clutch. Expert-Vetted (top 1%) on Upwork. If you want a team that writes maintainable code, tells you the truth, and is still there long after launch, that's us.
