the anti-agency engineering atelier
We founded Ship21 Studio with a singular mission: eliminate the multi-month agency bureaucracy and deliver production-grade native mobile applications at extreme velocity.
Why We Ship in 21 Days
Traditional agencies assign 1 account manager, 2 junior developers, and 3 project managers who spend 80% of their time writing status decks. We operate as a dedicated Senior Systems Unit: your backend APIs connect directly to our battle-tested React Native Expo 57 and RevenueCat boilerplate.
100% IP & Private VPC Ownership
You own 100% of the code from Day 1. Every commit is pushed directly to your private GitHub repository. AI models authenticate through your private Google Cloud Vertex AI or AWS Bedrock VPC with zero public training exposure.
Engineered on the
World's Most Robust Stack.
We use battle-tested, scalable technologies that give your application blistering speed, zero vendor lock-in, and hardened enterprise architecture.
Next.js 15 App Router & React Native Expo
Single type-safe TypeScript architecture for lightning-fast web consoles and 60 FPS native iOS & Android applications.
Instructor (Pydantic) & Vercel AI SDK
Zero hallucination schema enforcement, streaming UI tokens, and deterministic multi-agent state machines.
PostgreSQL pgvector (HNSW) & LlamaIndex
Sub-20ms dense vector similarity search, hierarchical document chunking, and Redis semantic caching.
Python FastAPI, Celery & Redis
Asynchronous background task queues, WebSockets, and low-latency inference pipelines deployed to private VPCs.
Google Vertex AI (Gemini 3.5) & Claude 3.7
Frontier multimodal vision, tool-calling pipelines, Zero Data Retention (ZDR), and zero public model training.
Stripe B2B & RevenueCat In-App Purchases
Automated recurring SaaS invoicing, Apple Pay, Google Pay, and frictionless multi-currency subscription tiers.
Langfuse Open-Source Tracing & Arize
Real-time token cost monitoring, latency telemetry, model evaluation, and complete audit logging for CTOs.
NeMo Guardrails & Private AWS/GCP VPCs
Automated prompt-injection filtering, PII/PHI redaction, and enterprise role-based access control.
why work with an engineering atelier instead of a bloated agency
We operate as a high-velocity Senior Systems Unit. Zero junior developers learning on your budget. Direct Slack access, daily Loom updates, and 100% source code ownership.
Senior Architects Only. Zero Junior Delegation.
Most agencies bill $60k+ for a bloated team of juniors learning prompt engineering on your budget. We operate like a specialized Special Forces engineering unit: 2 senior systems architects, direct Slack access, daily Loom updates, and clean modular code you can actually maintain.
21 Days
