Questions

Are you a SaaS development agency?

Yes. DayNight Studio builds SaaS products sprint by sprint - CRMs, dashboards and platforms with auth, billing and integrations. See NextFlow CRM.

Example product?

NextFlow CRM - lead capture, inbox, quotes, payments and AI replies shipped as a full product.

What does a sprint include?

A scoped slice of working software: design and engineering in the same team, staging access, and a clear definition of done. From £3,000.

Website or web app - how do we know?

If people mainly read and enquire, start with a website. If they log in, manage data or repeat a workflow, you need a web app. We advise before you commit.
