Custom SaaS & AI

Multi-tenant SaaS.
Built to ship.

Multi-tenant SaaS for founders who need more than an MVP template. We embed a senior engineering pod, design the architecture, and ship production-grade platforms — scaled to 100K+ users, 8K+ customers, and 60K+ entities with 99.9% uptime. Agentic AI workflows included when the use case calls for them.

What we ship

For Custom SaaS & AI.

Core deliverables we have shipped before in this vertical — not templates, real systems with runbooks.

Multi-tenant SaaS builds

Event-driven, multi-tenant architecture with tenant isolation at the data and API layers. REST + webhook API surface. Admin and analytics dashboards out of the box.

Agentic AI workflows

Production LLM agents with n8n orchestration, tool use, RAG pipelines, eval suites, and observability. Not demos — working agents with runbooks.

LLM document pipelines

Document extraction, transformation, and generation pipelines. Typically reduces manual processing work by 60-70% based on prior engagements.

Production observability

Grafana + Sentry monitoring, structured logging, distributed tracing, and on-call runbooks — delivered as part of every engagement, not optional.

MVP in 8 weeks

Fixed-budget, scope-controlled product builds for pre-Series A founders. Auth, payments (Stripe), and analytics wired from day one.

Engineering pod embeds

Long-form 12+ week engagements where a senior pod embeds with your team. PM, design, and engineering shipping together, weekly.

Compliance & data

Built right.
From day one.

Compliance is an architectural concern, not a checkbox. We scope the regulatory surface before writing a line of code — so you are not retrofitting controls at Series A.

SOC 2 patterns

Access control, audit logging, encryption at rest and in transit, and vulnerability management patterns aligned with SOC 2 Type II preparation.

Tenant data isolation

Row-level security and schema-per-tenant patterns. Tenant data cannot leak across API boundaries or query layers.

Secrets management

AWS Secrets Manager and environment-isolated config. No credentials in code or deployment artifacts.
