JSON Crew is a software housespecialized in one thing: digital sales transformation for manufacturing and product companies. We build the systems that shorten the path from a customer's first interest to a signed contract.
We don't sell isolated features — we build one connected system, layer by layer, wherever a company loses customers:
Websites that convert — audit and rebuild for SEO, UX and speed
2D/3D product configurators — customers explore options and see pricing before they call
Automated quoting — a clickable offer page in minutes, not a PDF
Interactive kiosks, showrooms and virtual tours
Custom B2B web apps, dashboards, client panels, mobile and IoT apps
AI and process automation
We also run products like: 1. JSON Hub — our own SaaS for CRM and automated quoting — and a managed lead-generation system. Running our own SaaS means we understand the product side operationally, not just from a brief.
Why companies pick us? AI-first delivery (Cursor + Claude) — a configurator MVP in 8 weeks, not 8 months; fixed price and clear scope on the first engagement; we turn down unclear projects, so you get concrete decisions, not open-ended billing.
Proof: for Akpil (agricultural machinery) we automated configuration and quoting for 150 inquiries a week, 60% near-identical. For KG Elektronik we built an IoT app App Smart Control managing 12,000+ connected devices with 1,000+ downloads and 4.9 score on Google Play.
Are you a manufacturer or product company? We're a fit if you wants sales to scale through tools and process — not headcount.
We're not a generic agency: if a project has no link to sales or the customer journey, we'll tell you so.

Our Story
We're JSON Crew! Three founders who believe sales is a system problem, not a people problem. A manufacturer can have a great product and still sell it like it's 2005, offers in Word or PDF the client never opens.
