A Better Way to Build SaaS
Cohesive helps you build the operational core your SaaS depends on—cleanly modeled, clearly defined, and ready to scale with less cost and friction.
What is Cohesive?
Cohesive is a domain modeling toolchain that turns your core business model into executable infrastructure—database structure, APIs, UIs, workflows, and integrations—from a single definition.
It doesn't replace your existing infrastructure stack. Instead, it provides a structured way to define and orchestrate it, connecting databases, services, APIs, UIs, and workflows into a coherent system.
By focusing on structure and behavior rather than low-level programming, Cohesive reduces accidental complexity and makes system development more accessible and precise.
Offerings
Cohesive Building BlocksThe Cohesive Building Blocks are a layered set of libraries that enable a semantically-oriented approach to systems engineering:
Cohesive ServicesWe work with clients to define:
- Executable domain models
- Explicit state transitions and invariants
- First-class projections for APIs, UIs, BI/ML tools, and integrations
- Runtimes that execute and monitor these models in production
- Operational, scaling and evolution plans
Who’s this for?
This is for teams building complex, long-lived systems who want semantic and structural clarity, operational resilience, and sustained velocity as complexity grows.
This is not for short-term projects, framework drop-ins, or organizations comfortable trading long-term integrity for short-term speed.
Engineers
- Explicit entities, transitions, invariants, workflows
- First-class projections instead of ad hoc read models
- Deterministic execution across runtimes
- Reduced architectural drift, coupling, boilerplate
- Incremental adoption without rewrites
Designers
- Clear state machines to design against
- Well defined workflows and error states
- Consistent semantics across UI, API, and reporting
- Fewer late-stage edge cases
- Higher fidelity between intention and execution
Executives
- Lower long-term maintenance cost
- Reduced operational fragility
- Faster feature evolution without structural collapse
- Clear alignment between business rules and system behavior
- Software that compounds value instead of tech debt
SaaS Isn’t Dying. It’s Being Rebuilt.
AI can generate code and interfaces. But real SaaS products are systems of record — with state, rules, and workflows that must remain consistent over time.
Without an explicit operational model, AI output becomes scattered across layers and difficult to maintain.
The future of SaaS is not replacement. It is SaaS built with AI on a structured foundation.
Cohesive provides that foundation.
Case studies
Cohesive was forged in complex, high-scale systems across productivity, e-commerce, logistics, payments, and healthcare platforms. Different industries. Same structural problems:
- Fragmented state
- Fragile workflows
- Search and reporting drift
- Reconciliation gaps
- Integration sprawl
Cohesive addresses these at the model layer — defining canonical state, legal transitions, coordinated workflows, and derived views that remain consistent across APIs, search, and storage.
