# Agasthya Joshi > Agasthya Joshi (AJ) is a founder and builder in Nottingham. He runs Revti.ai and Pact, and designs and builds brands, websites, apps and AI agents for businesses across the UK. I'm Agasthya Joshi, AJ for short. I'm a founder and builder based in Nottingham, studying Cyber Security at De Montfort University. I run two businesses of my own. Revti.ai is an AI front office: agents that answer and make calls, reply on WhatsApp, SMS and web chat, and book appointments. Pact books pre-qualified clients in with UK advisers. Clients tell me what they want and I build all of it: the brand, the website, the software and the AI behind it. KK Tax asked for a website and got a whole new brand. Pact started as an adviser's idea and is now a marketplace with web, Mac, Windows and phone apps. I grew up around my family's business, Royal Chai, and built its websites for five years. Before that I worked at McDonald's through school. Contact: aj@revti.ai. Book a call: https://agasthya.uk/contact. Start a project: https://agasthya.uk/start. Press kit: https://agasthya.uk/press.
