We don't just build apps. We fix how your business operates.

Questions before we get started.

Ask on WhatsApp

How much does a website or custom system cost?

A landing page starts at $200,000 ARS (or equivalent at the official exchange rate): custom design, up to 5 sections, technical SEO, and first-year domain. Custom management systems start at $630,000 ARS depending on features. Maintenance plans start at $60,000 ARS/month.

How long does it take to deliver a project?

A landing page takes 2–3 weeks from the moment we receive your materials. For custom systems, we set the timeline together after mapping your processes and requirements. No made-up deadlines.

Do you use WordPress, Wix, or templates?

No. We build everything with custom code. That gives us full control over performance, security, and the ability to fit each solution exactly to how your business works — no template restrictions.

What happens after launch?

We offer monthly maintenance plans so your solution keeps running and growing. The Basic plan covers changes and support for websites. Business and Enterprise include infrastructure management, databases, and priority response for complex systems.
