I’m Permjeet Kainth, founder of Rough Diamond, and I help business owners and professionals build meaningful, lasting relationships that drive real growth.
I’ve spent years connecting good people with good people, spotting opportunities others miss and turning conversations into collaborations.
I created Built to Last – Mastering Relationships in Business to help you transform everyday interactions into purposeful partnerships.
My work is rooted in the SPICE Framework and the Know, Like, Trust principle, ensuring people feel seen, heard, and valued.
My approach is practical, human, and honest. I empower individuals and organisations to communicate authentically, strengthen their networks, and lead with impact.
If you’re ready to turn contacts into results, let’s connect.
You don’t need to change who you are, just unlock your best version.


It’s great to see how Permjeet is so passionate about helping support people with their businesses. I’ve met Permjeet through networking in Nottingham and he has certainly been a prevalent individual in the local networking scene!


I really enjoyed working with Permjeet as my coach, he was very supportive and open.
I really appreciate the sessions being recorded and shared with me also so I could review the lessons and the advice given
I also enjoyed the opportunity to joint venture with him and how he has endorsed my practice.
It’s fantastic when business can work together!
