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. Based in Kraków, Poland.
