First Build

From Idea to Working AI Feature

You have the idea. You have the tabs open. Now actually ship something. Pick the right approach, build with modern tools, and walk away with a working AI powered feature, not a slide deck that ghosts you in week three.

Who, why & outcomes

Who

Developers, builders, PMs, and founders ready to ship their first real AI feature.

Why

Ideas are easy. A working feature that survives week two is the hard part.

Outcomes

A shipped AI powered workflow, clearer tool choices, and a certificate when you finish.

  • Find a real problem worth solving (not "ChatGPT but for cats")

  • Choose your approach without a 47 tab research spiral

  • Build in sandboxes. Break on purpose. Fix like an adult.

  • Ship something that survives demo day AND Tuesday morning

  • Modern tools. Zero "install Docker and pray" energy.

  • First 3 lessons free. Completion certificate when you finish the path.

Do not miss out

We can only support 200 accounts in the first cohort. First 3 lessons free, completion certificate included, and the waitlist fills faster than free pizza at a hackathon.

Reliable AI

Grounding, Evals & Production

Your demo wowed the room. Production laughed. Learn grounding, evals, guardrails, and how to tame hallucinations before they tame your roadmap.

Who, why & outcomes

Who

Engineers and PMs moving AI from demo to production.

Why

Impressive prototypes and embarrassed on call logs should not be the same project.

Outcomes

Grounded features, eval frameworks, guardrails, and fewer hallucination surprises.

Agentic Systems

Building Reliable Autonomous Workflows

Multi step agents that do real work, not theatrical loops that burn tokens and confidence. Design workflows that still make sense when nobody is watching.

Who, why & outcomes

Who

Builders designing multi step AI workflows and autonomous agents.

Why

Agents that loop forever look smart in demos and expensive in prod.

Outcomes

Reliable agent design, workflow orchestration, and systems you can operate calmly.

AI Strategy

Decisions & Precision Communication

Know when AI is the answer, when it is not, and how to explain both without sounding like a keynote or a doomer. Trade offs you can defend in the meeting.

Who, why & outcomes

Who

Leaders, PMs, and communicators deciding when and how to use AI.

Why

Bad AI strategy wastes budgets. Bad AI communication wastes trust.

Outcomes

Clear trade off decisions, accurate AI communication, and a certificate to prove it.

The human behind the grey

Vaibhav Kestikar

Senior Data Scientist. I got tired of explaining AI to smart people who'd been lied to by LinkedIn posts. So I built The Grey Project: depth, visuals, and zero hype. The way I wish someone had taught me.

If you've ever nodded along in a meeting while secretly Googling “what is a transformer model”? This is for you.
