Research-driven AI, software, blockchain, and cybersecurity engineering for hard technical problems
Dreamers Inc. is a research-driven engineering studio for organizations with technically difficult software and AI problems. We build private LLM and RAG systems, citation-grounded document intelligence, custom machine learning, GPU and cloud infrastructure, blockchain and Web3 systems, cybersecurity tooling and assessments, data platforms, workflow automation, and specialized web applications. 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. We focus on careful architecture, direct communication, and systems that keep working under real operational pressure.

We Define the Right Build Before We Start It.
A redesign. A rebuild. A new feature. The request you start with rarely tells the whole story. Goji Labs helps enterprise teams determine what the product needs before they commit significant time and budget to building it. We clarify the business outcome, examine what is standing in the way, and define the right response. Our clients are established organizations, including publicly traded and PE-backed companies. They come to us to: 1. Extend or accelerate a product that already works 2. Diagnose and revamp one that doesn't 3. Decide whether a new product opportunity justifies the investment Every engagement starts with a fixed-fee Strategy Sprint. Most run two weeks. You leave with a clear recommendation: what to do, why it matters, what success should look like, and what it will take to deliver. That recommendation becomes the brief for design and engineering. We test it with you before anything gets built. Then we build toward the outcome you agreed on. Selected results: -TGS: 405% increase in revenue-generating traffic. -Insurance: 38% lift in quote-to-policy conversion. -Mitsubishi's AnyMile: 35% reduction in route planning time. AnyMile went on to win Best of CES 2023. Goji Labs is headquartered in Los Angeles, with an office in New York.
“They conducted a thorough audit of our internal app and delivered clear, actionable insights that helped us move forward confidently.”

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.
