David Riha

AI Digital Twin Builder

David Riha is the Founder and CEO of BuddyPro, a ground-breaking AI platform that turns elite coaches, experts bestselling authors, and thought leaders into highly profitable AI digital twins - always-available AI versions of themselves that coach clients 24/7 and have human-lilke behaviour, memory and empathy.
 
David and his team defined a new category of digital products, relationship-based AI coaching trained on the expert's knowledge that gives very similar experience as talking with the real coach. And people are willing to pay for it - some of the most successful AI coaches built on BuddyPro see extremely high conversion rates from free trials, and people are paying thousands for a subscription.
 
Based across San Francisco, Prague, Canada and Bali, David has spent over a decade building software products, including an award-winning mobile app and a VR gaming studio. He founded BuddyPro in 2024 after building an AI coaching prototype for his brother Pavel, an online business strategist. That first AI twin generated $282K in annual subscriptions from 237 customers within 30 days - validating a new category of knowledge monetization.
 
Since then, David helped to launch 130+ AI coaching clones on the BuddyPro platform, collectively generating over $4.5M in subscription revenue for the experts and coaches. Clients of BuddyPro include Jen Gottlieb, Marie Diamond (feng shui master featured in The Secret) or Joanna Wiebe (pioneer of conversion copywriting). BuddyPro won the San Francisco AI startups competition against 100+ entrants in March 2026.
 
David built Buddy, the proprietary AI companion engine powering every twin on the platform - designed not as a chatbot, but as a system that forms real mentoring relationships. Top-performing AI twins on BuddyPro achieve 60% daily retention and 95% monthly retention.
 
He offers complimentary custom builds to qualified world-class experts, handling the entire AI twin creation. Experts share their knowledge; David and his team do the rest.
