/ Industries
Operations software tailored to your industry.
Every industry runs its own way. Instead of making you bend to off-the-shelf software, Nyx writes it for exactly how you operate — bought outright, source to your GitHub.
Gym management software, shaped around how your gym actually runs.
From 15M ₫ · 2–3 weeksCheck-in, packages, PT scheduling, Zalo reminders and a revenue board — software written for your gym, bought outright, no monthly rent.
Gyms of 50–500 members usually still run on Excel and Zalo: members who quit two months ago still get auto-charged without the owner knowing, PT schedules clash, and 12+2 promo packages don't add up in any off-the-shelf tool.
Check-in & packages
QR check-in, 1/3/6/12-month packages and promo combos that add up to the đồng.
Clash-free PT scheduling
Book trainers without time clashes, track completed sessions.
Zalo member reminders
PT reminders 2 hours before, renewal reminders 7 days before — automatic.
Payments & revenue
Collect via VNPay/MoMo. A board showing active vs lapsed members, PT vs package revenue.
Why not off-the-shelf SaaS. Instead of KiotViet for Gym / Sapo POS. Those are retail POS tools relabelled "gym" — they can't handle 12+2 packages or per-session PT pay, and they make your gym bend to them. Nyx does the opposite, fitting how your gym runs — and you pay once, no monthly rent.
From 15M ₫Centre management software, shaped around how Vietnamese centres actually run.
From 15M ₫ · 2–3 weeksAttendance, session packages, per-session teacher pay, Zalo parent reminders and tuition — written for centres of 100–500 students.
Centres sell 8/12/24-session packages, allow make-up classes, and pay part-time teachers per session. Public-school software can't do this, and doing it by hand is error-prone and slow.
Attendance & packages
8/12/24-session packages, make-up rules configured per centre.
Part-time teacher pay
Auto-calculates per-shift/per-session pay for hourly teachers, no manual tallying.
Zalo parent reminders
Message parents after each session and when a package is running low.
Tuition & reporting
VNPay/MoMo tuition portal, clear receivables and revenue reports.
Why not off-the-shelf SaaS. Instead of Edusoft / ClassIn / MISA EMIS. They're built for the public-school semester model, can't handle session packages or per-shift part-time pay, and charge a 10–11M setup fee per module. Nyx fits your centre's actual rules, with one published price.
From 15M ₫Content-studio workflow software, with no per-head fees.
From 15M ₫ · 3–4 weeksA Research → Write → Review → Publish board, per-brand briefs, a freelancer portal with no per-seat cost, and multi-channel auto-publish — written for studios of 3–15 people.
Studios on Notion pay $10 a month for EACH freelancer just to see a task — 12 writers is 1.4M/month, forever. And Notion breaks once you have many brands and outside freelancers.
Workflow board
Research → Write → Review → Publish, with per-brand briefs.
Zero-per-seat freelancer portal
Outside writers join via a Zalo link, with no per-seat fee like Notion.
Review & Discord alerts
Review drafts inline, get a Discord ping when something needs approval.
Multi-channel publish
Publish straight to WordPress / Ghost / Facebook. Optional research agent.
Why not off-the-shelf SaaS. Instead of a Notion "Content Agency OS" template. Notion charges $10 per head every month and breaks past 5 people or with outside freelancers. Nyx is purpose-built: outside writers join via a Zalo link, with nothing extra, paid once.
