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
Internal/public APIs — REST/GraphQL, docs, rate-limit
Internal tools (admin panels) — Retool alternative
Migrations from Excel/Access/legacy systems

Our process

01. Product spec

User stories, DB schema, Figma mockups. Validated before code.

02. Iterative build

2-week sprints, demo at end of each, continuous preview access.

03. Launch

Production deploy, monitoring (Sentry, Plausible), training, full repo handoff.
