VantyRex Systems
Built complete. Websites, ordering and booking systems, apps and full platforms for businesses.
What we do
VantyRex Systems is a custom software engineering company. We design and build complete websites, web and mobile applications, and end-to-end business systems — every build starts from scratch and is engineered around one client's business. No templates, no recycled themes. Projects are delivered with digitally signed contracts, phase-by-phase milestone tracking, and automated deadline reminders.
Built complete. Every build ships with search visibility (SEO, GEO and AEO), the legal pages Israeli law requires, and three languages (Hebrew, Arabic, English). 8+ projects delivered for local businesses, from websites to complex systems and workflows.

Frequently asked questions
What does VantyRex build?
Complete websites, web and mobile applications, and end-to-end business systems — including client portals, digital contracts, billing, and automation. Every build is custom; we do not use templates.
Who owns what?
Your brand, your data and your client-facing product are yours. VantyRex's backend logic and infrastructure stay ours, licensed to you to run your product and never handed over — the exact terms are fixed in a signed agreement before work begins.
How is pricing set?
By scope. After a free discovery call you receive a fixed written proposal with the price, timeline, and deliverables. No hourly surprises.
How long does a project take?
A business website typically takes 2 to 3 weeks, a booking system 3 to 5, an ordering system 4 to 6, an app 8 to 12 and a platform 12 to 20 weeks, from signed contract to launch. Your proposal includes a committed timeline with milestone tracking.
How do I track progress?
Every project runs on our contract platform: a digitally signed agreement, phase-by-phase progress tracking, and automated deadline reminders.
Is there support after launch?
Yes. Every delivery includes a defined support window, and ongoing SLAs are available — including 99.9% uptime targets and priority response times.
Is a custom build better than a website builder or template?
Builders and templates give you a look; VantyRex gives you a system. Your build is engineered for your exact workflow, carries no per-seat SaaS lock-in, scales as you grow, and is yours to run. Templates cannot deliver real business logic, deep integrations, or the client portals and contract platforms we build.
Do I own the source code?
Your brand, your data and your client-facing product are yours. Buying out your product's source code is your right, set as an option in the agreement. VantyRex's backend logic and infrastructure stay ours: licensed to you to run your product, never handed over, and not included in any project price or buy-out.
How does the client portal work?
Your clients log in with the email or phone on their agreement, confirm a one-time code, and see live project status: phases, progress, deadlines, and their signed documents. There are no passwords to manage, and each client sees only their own projects.
Are your digital contracts legally binding?
Yes. Each contract is signed by VantyRex, then by you with identity verification and a handwritten e-signature, and sealed with a cryptographic hash for non-repudiation. Both parties receive the executed PDF, which is the binding record.
Do you offer a cybersecurity retainer?
Yes. We provide continuous monitoring, hardening, and incident response on a monthly retainer, with response-time targets defined per severity tier and clear reporting you can act on.
Can you build AI and automation systems?
Yes. We design and deploy AI-driven and autonomous systems — from lead capture and follow-up automation to custom models and inference infrastructure — engineered into your operations rather than bolted on.
Do you work with international clients?
Yes. We are based in Israel and serve clients worldwide in English, Hebrew, Arabic, and Russian, with full right-to-left support. Engagements run remotely on our contract platform.
What does a project cost?
It depends on scope — and you will never have to guess. After a free discovery call you receive a fixed written proposal with the price, timeline, and deliverables before any work or payment begins.
