What powers the StartCore SaaS Engine
A production-ready foundation for multi-tenant SaaS products — from the AI layer down to the database.
AI layer
Summaries, relationship intelligence and assistive automation powered by leading AI models.
Multi-tenant
Isolated workspaces, organizations and teams running on a single shared, scalable infrastructure.
Workspace engine
Configurable modules, fields, pipelines and processes that adapt to each business model.
Row-level security
Granular access rules enforced at the database level, so every tenant only sees its own data.
Event / outbox engine
Transactional outbox with QStash delivery, dead-letter queues (DLQ) and cache correctness, so events fire exactly once and your data stays consistent.
Billing
Plans, subscriptions and usage-based billing ready to monetize your platform.

A production-ready application foundation, yours to keep. Build your SaaS without starting from scratch.

Custom development
Need a workflow of your own? We build your next SaaS, CRM or client portal on the StartCore SaaS Engine.
If your commercial operation doesn't fit a generic CRM, StartCore can adapt to your business model with custom flows, your own operating logic and a white-label experience ready for your team or your clients.
StartCore isn't just a closed product. It's built on an enterprise SaaS Engine designed to support workspaces, permissions, commercial modules, relationships, files, notes, pipelines and configurable processes.
That lets us build custom implementations for companies, agencies, consultancies and service providers that need a system adjusted to their real operation — without starting from scratch.
Custom workflows
We design processes adapted to your operation: sales, onboarding, renewals, support, partnerships, client management, vendors, internal approvals or any specific commercial flow.
Tailored business logic
We adapt rules, states, permissions, fields, validations, views, modules and automations to how your company works.
White-label implementation
We create an experience with your brand, your domain, your colors, your copy and your processes — on top of StartCore's base infrastructure.
Enterprise SaaS foundation
We build on an architecture ready for workspaces, multi-tenancy, permissions, security, scalability, configurable modules and progressive growth.
You don't need to build a SaaS from scratch to have your own platform. The StartCore SaaS Engine accelerates internal systems, commercial portals, vertical CRMs, agency platforms, client portals and custom operational tools.
Where it applies
- You need a vertical CRM for your industry.
- You want to offer a platform under your own brand.
- Your team works with non-standard commercial processes.
- You need to connect companies, people, files, notes and deals in a flow of your own.
- You want to digitize an operation that lives in spreadsheets, WhatsApp, Notion or disconnected tools.
- You want to launch an internal or external SaaS without building the whole technical base from scratch.
