How the intro call works
Everything you need to know before booking
Thirty focused minutes with a senior engineer — no slide decks, no sales pitch. Here's how we make it useful.
- 30 minutes over Google Meet. We'll send a calendar invite with the link once you book.
- A senior member of our team — usually an engineering or product lead — who can scope your project end-to-end and answer technical questions on the call.
- Nothing formal. A short description of the problem you want to solve, any rough timeline or budget, and links to existing products or designs (if you have them) are more than enough.
- All slots are displayed in London time (Europe/London). The calendar invite will adapt to the time zone of your calendar automatically.
- No. The intro call is free with no obligation. If we're a good fit, we'll follow up with a written proposal and fixed-scope plan within two working days.
- If we agree to move forward, you'll receive a written proposal covering scope, milestones, team, timeline and a fixed price. From there, kick-off is typically within 1–2 weeks.
- Yes. Reply to the confirmation email at least a few hours before the slot and we'll reschedule. There is no cancellation fee.
- Happy to. Send your NDA to info@rudrax.co.uk before the slot and we'll have it signed in time for the meeting.
