What does SprintStack.digital build?

SprintStack builds SaaS products, mobile apps (iOS, Android, Flutter), enterprise business software, ERP systems, CRM platforms, automation workflows and API integrations for startups, growing businesses and enterprises.

How does the fixed sprint delivery model work?

We work in transparent fixed 2-week sprint blocks with agreed scope. Clients receive a written architecture document before development begins, review working software at each sprint demo, and receive full source-code and IP ownership at every milestone.

Do clients get 100% source-code and IP ownership?

Yes. All code, database schemas, architecture documents, cloud configurations and API documentation are handed over with full intellectual property assignment. There is no vendor lock-in.

Which countries does SprintStack serve?

SprintStack serves clients in India, USA, UK, UAE, Singapore and Australia with English communication, timezone overlap, NDA-led confidentiality and weekly sprint demos.

Does SprintStack build attendance and workforce management software?

Yes. SprintStack has a production-ready Attendance and Workforce Management ERP with GPS geofencing, biometric device sync, shift scheduling, leave approvals and payroll-ready exports.
