How long does a typical OpenAI engagement take?

Timelines depend on scope. Discovery usually takes 1–2 weeks; MVPs often ship in 4–10 weeks; larger platforms are delivered in phased releases with clear milestones.

Can you integrate with our existing systems?

Yes. We routinely integrate with APIs, data warehouses, CRMs, ERPs, cloud services, and internal tools while preserving security and compliance requirements.
