JSON Crew

JSON Crew is a software house with one specialization: digital sales transformation for B2B manufacturers and distributors. 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:

• 2D/3D product configurators — customers explore options and see pricing before they call
• Automated quoting — a clickable offer page in minutes, not a PDF
• Websites that convert — audit and rebuild for SEO, UX and speed
• Interactive kiosks, showrooms and virtual tours
• Custom B2B web apps, dashboards, client panels, mobile and IoT apps
• AI and process automation

We also run JSON Hub — our own SaaS for automated quoting — and a managed lead-generation system. Running our own product means we understand the operational side, not just the 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. You work directly with the three founders — no account managers. 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 — quote time dropped from 2 days to 30 minutes. For KG Elektronik we built an IoT app managing 12,000+ connected devices: 1,000+ downloads, 4.9 on Google Play. For Colliers we delivered a VR/3D virtual design lab integrated with Power BI.

Are you a manufacturer or product company? We're a fit if you want 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 say so upfront.
