When does custom make sense?

No off-the-shelf tool covers your exact business process.
You pay 5 SaaS that don't talk to each other — high cost, siloed data.
You need a workflow ultra-specific to your industry.
You want competitive moat via proprietary tooling.

What we build

Multi-tenant SaaS — auth, Stripe billing, admin dashboard
Custom ERP/CRM — clean domain model, no kludges
BI dashboards — real-time KPIs, alerts, exports
