Proprietary systems and AI apps
Internal apps, CRM, portals, quote generators, dashboards and AI automation designed around your processes, not a pile of generic tools.
Your company should not depend on a pile of tools. We replace the friction with a proprietary system you can steer.
What we build is yours: the code, the data, the hosting.
A proprietary system brings an internal app, a database, automations and dashboards together in an architecture you control, replacing scattered files, patched together tools and manual processes. Digisimma builds these systems in Next.js, with CRM, analytics and scoped AI integrations.
We design proprietary systems for organisations that have outgrown the SaaS pile, with data governance, permissions, executive reporting and ERP or CRM integrations.

Proprietary systems, integrations and timelines: answers before you launch your scoping.
Yes, we connect through APIs whatever stays relevant (CRM, accounting, Sheets) and gradually replace what creates friction. No mandatory big bang.
Yes, often during the transition phase or for executive exports. The goal remains a structured proprietary database.
Yes, client portals with authentication, deliverables, tracking and notifications are part of the systems we build.
No, AI is added where it reduces human time (sorting, assisted writing, routing). The foundation stays business, data and process.
Prototype 7 to 10 days, MVP 3 to 6 weeks, complete system 6 to 12 weeks depending on scope. Ad Excelsum System: custom scoping.
Yes, a prototype or MVP focused on a single process, then extended in sprints. That is the recommended approach.
Free scoping of your need: prototype, MVP or complete system, depending on your maturity.
