We build operational B2B SaaS platforms used by enterprise customers.

We engage at the start of a build or when a product has outgrown its early architecture: when roles multiply, data models break, workflows accumulate edge cases, or a B2B tool begins moving upmarket and needs to meet enterprise-level requirements.

With 14 years of experience and 80+ products shipped, we have a particularly strong track record in:

→ GRС/Compliance SaaS
→ HR and Payroll SaaS
→ Workflow Automation
→ Low-Code / No-Code Platforms
→ Legacy App Modernization
→ AI Integration in B2B SaaS

We've done this before, at scale:

SmartSuite (Work Operating System) → Built from scratch. 7M+ users, $1.2M ARR in 4 weeks post-launch, $38M raised. Used by companies like Capital One

Globalli (HR and payroll platform) → Enterprise compliance logic across 125+ countries, we helped to built from the ground up, $15M+ raised.

⚙ WHAT WE SOLVE

• Permission Chaos: Growing roles and fragile access logic slowing your team. We design an RBAC architecture that scales without requiring later rebuilds.
• Breaking Data Models: New features require changing everything. We build multi-tenant data models designed for scale from day one.
• Workflow Complexity: Business logic harder than the code itself. We implement workflow engines that handle edge cases without breaking down.
• Scaling to Enterprise: Product built for SMB now needs audit trails, data segregation, and compliance readiness. We add the enterprise layer progressively, no full rewrite required.
• AI Readiness: Scattered data and broken integrations blocking every AI initiative. We design the clean foundation that makes AI features actually buildable.
