01·MANIFESTO
Silver is the machine. Gold is the result.
Silver is our method: engineering and automation doing the heavy lifting. Gold is what you keep: software in production, measured in users, sales and hours saved. Your fixed-price quote comes first — numbered modules, a price on each, no surprises. The meeting is spent on your project, not on convincing you.

What every client asks
How much does custom software development cost in Mexico?
Projects at Johto Developments range from MXN $50,000 to MXN $2,000,000 depending on scope. Every quote itemizes numbered modules with individual prices, so you know exactly what you are paying for. You get the full number in 48 hours, before any meeting.
How much does it cost to implement AI or an AI agent?
It depends on the process: an AI automation module within a project typically starts at MXN $50,000, and a full agent-driven platform can reach MXN $2,000,000. We build agents, copilots and unsupervised workflows — like Marea IA, running in production with 23 tools connected through chat and WhatsApp.
How does the 48-hour quote work?
You tell us about your project in your own words and we do the full scoping. Within 48 hours you receive a professional PDF with numbered modules, per-module pricing, a clear total and CFDI invoicing. The meeting comes after, with the numbers already on the table.
What services does Johto Developments offer?
Custom web platforms (dashboards, e-commerce, SSR), AI implementation and automation (agents and copilots), corporate websites, and native iOS/Android mobile apps. All built by our own senior engineering team in Mexico City.
Do you work with US companies (nearshore)?
Yes. We work remotely with companies across Mexico, LATAM and the United States, fully bilingual in Spanish and English. For US clients we operate as a nearshore studio in your same time zone, delivering fixed-scope projects — not staff augmentation.
What results have you shipped?
Marea Alcalina, our flagship AI e-commerce platform, serves 200,000+ users with 3,000+ automated tests. Our AI photo products total 80,000+ users and 500,000+ generated portraits. Overall, 50+ projects delivered to production.
