Why DJUST and Theodo make a formidable product duo

Theodo and DJUST share the same obsession: building products that truly matter to their users. The webinar co-hosted on Product Discovery perfectly illustrates this complementarity: Theodo provides the product methodology, while DJUST provides real-world field experience.

1. Product Discovery: building what really matters

Theodo brings proven Product Discovery expertise to ensure every DJUST feature addresses a real user need before investing in development. Less product risk, higher adoption.

2. Custom integration with existing IT systems

Theodo designs integration architectures between DJUST and clients' existing systems (ERP, CRM, PIM, legacy), leveraging an API-first approach and high-level engineering practices.

3. AI embedded in DJUST projects

Theodo integrates AI into DJUST projects in an operational way: automating order workflows, AI agents, and analyzing buyer behavior. AI isn't an add-on module; it's a performance driver from the start.

4. High standards for quality and delivery speed

With Lean Tech®, Theodo guarantees projects are delivered quickly, without technical debt, and with a level of quality measured in production. No delays, no surprises at go-live.
