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.

Growth Division

Growth Division is a growth marketing agency for startups, scale-ups and ambitious SMEs - expert-led and powered by GREX AI, our AI growth platform.
Trusted by 130+ high-growth businesses and rated 4.7 on Clutch across 31 reviews. We use the Bullseye Framework to prioritise the channels most likely to work for your stage and market, then run structured, ICE-scored growth experiments to prove what scales - so you can grow customer acquisition while holding an agreed cost per acquisition.
You get senior channel specialists across SEO, paid search and paid social, LinkedIn ads, outbound, content and ABM - not juniors, and not a retainer of undefined hours. Built by founders, for founders.
“I think Growth Division's approach to marketing is fantastic. They work with experts to validate a channel, rather than hiring a team. This means I can work with the best freelance talent on a flexible basis to test a channel. If it doesn't work, I can stop and test another channel. I really like this approach.”
