We build products. AI-first, full stack.
Apyx is a product engineering studio specializing in AI/ML development and full-stack software. We ship custom AI agents, fine-tuned models, and production-grade web products - and can embed senior engineers directly in your team when you need it.
What we do.
Six ways we ship. AI & ML first - plus the full-stack work that gets products to production.
AI & ML development
Custom agents, fine-tuned models, RAG pipelines, and eval harnesses - shipped to production. We build AI that works in the real world, not just in demos.
Learn more →Custom web applications
Typed, tested React/Next builds from greenfield to post-launch. Your team gets a codebase they can maintain - not a black box.
Team augmentation
Senior engineers embedded in your squads for 3–12 months. We ramp in days, leave documentation behind, and match your process.
Technical advisory
Architecture reviews, hiring panels, and fractional CTO engagements for founders and directors without a full platform team.
Rescue projects
Take the console, untangle the build, and ship the next release. We land fast, triage hard, and leave the fire out.
Platform migrations
Headless commerce, monolith-to-services, framework jumps. Behind a proxy, one slice at a time, with zero cutover downtime.
AI & ML development is our edge.
We build custom AI agents, fine-tuned models, and retrieval pipelines that go to production - not just to demo. From carbon markets to fashion intelligence, we've shipped across industries.

Narrow, deep fluency. We pick tools we'd stake our reputation on, then stay sharp in them.

Production-grade AI: custom agents, fine-tuning, RAG, evals, inference.

Questions, answered.
The ones we hear in the intro call, up front.
A 20-minute intro call so we can understand the work and decide if we're the right shop for it. If we are, we scope a short discovery week - paid, flat fee - that ends with a written plan, timeline, and price for the build. You own the plan whether you hire us or not.
Both, depending on risk. Well-scoped features go on fixed price so you know what you're buying. Open-ended work - rescue, discovery, anything with unknowns - runs on weekly team rate with a cap we agree on up front.
The senior engineers you meet in the intro call. We don't run a bench of juniors behind a staff-aug front. Team size is 1–4 people per engagement - enough to ship fast, small enough that everyone holds the whole system in their head.
Yours, in the overwhelming majority of cases. We'll push back if the stack is actively harming the goal - but leaving you with a codebase your team can maintain always wins over our preferences.
Usually 2–3 weeks from signed SOW, occasionally sooner. We hold the discovery week for new clients inside that window so the ramp isn't dead time.
You get the repo, the infra, the runbooks, and a two-week warranty against regressions. If you want us on retainer for follow-on work or advisory, we offer a lightweight month-to-month that most clients keep for about a year.
