FAQ
What you usually want to know
Direct answers to the most common questions before we start.
How long does a project take?+
A landing can be ready in 1–2 weeks; a custom product usually takes 4 to 12 weeks depending on scope. On the discovery call we give you a realistic estimate.
Who owns the code?+
You do. Once the project is finished and settled, you receive all source code and the IP of the deliverables.
How do payments work?+
We work in milestones: a deposit to start and payments against deliveries. That lowers your risk and shows steady progress.
Do you offer post-launch support?+
Yes. We include a post-launch support period and offer optional monthly maintenance plans.
Do you work with clients abroad?+
Yes. We work remotely with clients in any country, in Spanish and English, via video call or WhatsApp.
Do you sign an NDA?+
Absolutely. We sign an NDA whenever you need one and treat your information and your business with full confidentiality.
