Custom software,
forged in the night.
Stellar Nyx builds bespoke AI-powered SaaS applications for small and medium businesses. We take the work nobody else will touch — the messy spreadsheets, the gnarly workflows, the one-off integrations — and turn it into software your team actually wants to use.
What we build
Every SMB has problems software vendors won't solve. We do.
Internal tools & dashboards
Replace the tangle of spreadsheets and shared docs with a single source of truth your team can actually use day-to-day.
AI agents & automations
Stop paying people to copy-paste between systems. We build agents that handle the repetitive work so your team can focus on the rest.
Customer-facing portals
Branded client logins, booking flows, and self-service tools that make you look like the company you want to be — not the one you started as.
Integrations & middleware
Connect the systems you already pay for — CRM, accounting, scheduling, inventory — so data flows where you need it without manual exports.
Custom SaaS products
Have an idea you want to sell to your industry? We've shipped vertical SaaS from blank canvas to first paying customer in under 90 days.
Maintenance & iteration
Already have software but it's stuck? We take over legacy apps, ship the next version, and keep it running so you don't have to.
From idea to live app
Four steps. No ten-page proposals. No three-month discovery phases.
Discovery call
A 30-minute conversation. You explain the problem. We tell you whether we're the right team to solve it.
Fixed quote
Within 5 business days you get a written scope, timeline, and price. No hourly billing surprises.
Ship in sprints
First working demo in 2 weeks. Weekly check-ins. You see progress as it happens, not at the end.
Launch & support
We hand over the code, the docs, and the keys. Optional retainer if you want us to keep iterating with you.

The faster you tell us the problem, the faster we can tell you if we can solve it.
