The problem

Most companies pour money into tools they will never own

Every month, businesses pay software vendors for the right to use software they can never keep. Stop paying and it's gone. You're not a customer — you're a tenant renting your own IT. And that means:

Own your infrastructure
  • lock_open
    Vendor lock-in You depend on a single vendor. When something breaks, all you can do is watch and hope they fix it fast.
  • savings
    Price hikes you can't fight Vendors raise prices whenever they want. Your only options: pay the new price, or move away — which lock-in makes painful by design.
  • block
    No control when it counts Want to add a feature, or strip out bloat you'll never use? You can't. The roadmap is theirs, not yours.
  • verified_user
    You're a target Mega-platforms are mega-targets. A breach, an outage or a sudden policy change is entirely out of your hands.

How working together looks arrow_forward

„But the big-name products are the standard...“

How your business benefits from NexaStack

Standard doesn't mean there's no alternative. Here's why the switch pays off.

Independence

Financial predictability

When you run your own open-source software, software price hikes stop being your problem.

With NexaStack, you own the house.

No more living by someone else's terms.

03

Growth without regret

With NexaStack you hit no license limits — no account gets locked, no feature hides behind a paywall.

10 users or 100 — the same fair per-seat rate, no volume surcharge. Your server, your software, your freedom.

Your move to us

"Will our data come along too?"

If you want it to — yes. You don't have to lift a finger. We take your existing data — files, contacts, calendars and more — and make sure everything lands where it belongs after the switch.

How much does migration cost? The effort depends on your existing systems. We look at it together and give you a concrete price — transparent, based on actual work.
  • 🗃
    Your filesWe pull everything out — whether it's Google Drive, OneDrive or Dropbox.
  • 📅
    Calendars & contactsAppointments and addresses land fully on your new system.
  • 🗄
    CRM & project dataLeads, contacts, open tasks — we bring over what you need.
  • 📵

Your return: With a SaaS subscription you pay monthly license fees for the mere right to use the software — stop paying and the software is gone. With NexaStack you pay a one-time setup and then a fixed monthly price per plan for operation — your data, open formats, a documented exit.
