AI-powered SaaS for SMB

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.

Process

From idea to live app

Four steps. No ten-page proposals. No three-month discovery phases.
