We prove it with results, not promises. If we can't show you a satisfying result within the first 30 minutes of the session, you get a full refund — no questions asked. That's how confident we are.
30 minutes to a real result on screen
In the first 30 minutes, James plans with you, builds an initial version, and deploys it to a test server — all live on screen.
Plan and prioritize
We listen to your idea and decide together what to build first.
Build the first version
We demo Claude Code prompts and skills on screen, building a working first version.
Deploy to a test server
We deploy to a real domain right there and confirm it's working.
If you're still not satisfied after seeing this, the full 4-hour consulting fee is refunded.
Live demo and know-how, all at once
A rough idea is enough. James asks the right questions and demonstrates Claude Code prompts and skills on screen as we build together.

By the end of the session

Frequently Asked Questions
The questions clients ask most often before commissioning a build.
Q Can non-developers get consulting?
Absolutely! Many non-developers inquire about creating services using AI and no-code tools.
Q What topics can I consult on?
You can consult on IT startups, MVP development, AI usage, vibe coding, freelance/agency operations, marketing, and more.
Q How do refunds work?
If you request a refund within the first 30 minutes of your session, we'll fully refund you. After that 30-minute window, refunds aren't available.
Q How are sessions conducted?
Sessions run online via Google Meet. Once payment goes through, your confirmation email includes the Meet link. You can share your screen and walk through actual code, designs, or business materials together.
Q How should I prepare before a session?
Nothing is required, but if you jot down the problem you want to solve, your questions, and your current situation, we can dive much deeper within the limited time. Feel free to share repo links, planning docs, or links to competing products in advance.
Q Can I reschedule or cancel?
You can reschedule up to 24 hours before the session — contact support and we'll move you to another available slot. No-shows or cancellations within 24 hours may not be eligible for a refund.
Q Is what I share confidential?
Anything you share during a session — business ideas, code, planning materials — is never shared externally. If you need a separate NDA signed, just request it ahead of time.
Q Can I ask follow-up questions after the session?
Short follow-up questions by email (james@heyjames.ai) are welcome and answered as time allows. For deeper follow-ups, please book another consulting slot. Repeat clients often opt for the 10-session sprint package.
Q Do you offer team or company-wide consulting?
Yes — group consulting for startup teams, agencies, and in-house dev teams runs on a custom quote. Reach out via support with your team size, topic, and preferred schedule and we'll put together a plan.
Q Can I pay with a government startup grant?
Yes! Many clients have paid using grants from programs such as the Youth Startup Academy, Pre-Startup Package, Early-Stage Startup Package, Social Enterprise Support, and the Re-Challenge Package.
