Jev + LLM hybrid AI architecture

Jev + LLM.
Typed decisions. Selective reasoning.

Jev, TypeSafe AI’s decision model, evaluates bounded questions. Your code routes routine work to rules and tools, calls an LLM for complex interpretation, and brings a person in when the stakes demand it.

INTELLIGENCE, ROUTED WITH INTENT

Decide precisely.
Reason when needed.

One request. The right handler. Explore how typed decisions, application rules and LLM reasoning fit together.

01 / Understand

Client request

Receive a request with relevant account, policy and workflow context. Keep access checks and data minimisation in application code.

Step 1 of 6

Reduced motion: use the steps or playback controls. Visual motion is disabled.

Jev is by TypeSafe AI. Original TypeSafe AI logo from its official documentation. Independent architecture illustration; no partnership or endorsement implied. No live model calls are made.

A reference architecture to evaluate on your data. Jev’s learned decisions can be wrong; confidence is not a correctness guarantee. TypeSafe’s intent-routing pattern and confidence guidance inform this illustration. It models read-only tool work before review; side-effecting actions wait for approval.

Built to ship

We measure progress in working software.

Every engagement ships into your GitHub from week one: agents, pipelines and platforms you can open and test, not a status deck. This is what a build looks like while it runs.

    You have a well-defined product vision, a clear set of deliverables, and want a predictable investment with defined milestones.

    • Defined scope, timeline and investment upfront
    • Milestone-based delivery with clear acceptance criteria
    • Ideal for product launches and platform builds
    • Fixed investment, no scope-creep surprises
  • Time & material

    Your requirements are evolving, you need room to pivot, or you want to scale engineering capacity up or down as the product grows.

    • Flexible scope that adapts to evolving needs
    • Sprint-based delivery with weekly progress visibility
    • Scale engineering capacity on demand
    • Transparent investment tracking per sprint
  • Dedicated pod

    You need a long-term partner: a dedicated squad that works as an extension of your team, inside your processes and culture.

    • Dedicated squad assigned only to your product
    • Full integration with your tools, rituals and culture

Questions Founders Ask Us

Everything about working with RapidStackLab, from first contact to post-launch.

Quick answers

What does RapidStackLab do?
RapidStackLab is an AI-native product engineering firm. Senior engineering pods build autonomous AI agents, SaaS platforms and cloud infrastructure for funded startups and enterprises in the USA, UK, UAE and India. Details
How much does it cost?
Projects start at $12,000 for a production MVP. Most builds cost $25,000–$65,000. Dedicated pods run $12,000–$25,000 a month and managed SRE $4,000–$10,000 a month. Details
How long does an MVP take?
A production MVP takes 6–10 weeks: 1–2 weeks of discovery and architecture, then two-week sprints with a working demo every week, then a load-tested launch. Details
Who owns the code?
You do. Every engagement includes 100% code ownership: full IP transfer, your own GitHub repository from the first commit, and an NDA before you share anything sensitive. Details
How does RapidStackLab engage with new clients?

We start with a free strategy call to understand your goals, then move through our 5-step process: Discover, Design, Engineer, Scale, and Support.

What is your pricing model?

We offer fixed-price project engagements and dedicated team retainers. Pricing depends on scope, complexity, and timeline.

What technologies do you work with?

Our core stack includes React, Next.js, Node.js, Python, AWS, Docker, Kubernetes, PostgreSQL, MongoDB, TypeScript, Flutter, and TensorFlow.

Who owns the code after the project?

You do. All source code, IP, and assets are fully transferred to you upon project completion.

How long does a typical project take?

MVPs typically take 6–12 weeks. Enterprise platforms range from 3–6 months depending on scope.

Do you provide post-launch support?

Yes. We offer ongoing maintenance retainers covering bug fixes, performance monitoring, and feature iterations.

Who will be working on my project?

Every engagement is staffed with a dedicated project lead, one or more senior engineers, and a QA specialist. You will have a single point of contact throughout the project. We do not offshore work to junior contractors — the team you meet in the discovery call is the team that builds your product.

How do you keep clients informed throughout the project?

We use a shared Slack channel for day-to-day communication, a Notion workspace for documentation and sprint planning, and a bi-weekly video call for sprint reviews and planning. You have full visibility into the backlog, progress, and blockers at all times. We believe radical transparency is the foundation of a successful partnership.
