Founder of the AI consultancy Prompt Advisers, YouTube creator on AI agents and automation, O'Reilly live-course instructor and owner of the paid Skool community Early AI-dopters.
Mark Kashef is an AI consultant and educator who teaches practical use of generative AI, AI agents and automation tools such as Claude Code, Codex and n8n. According to his own website and the Prompt Advisers about page, he has more than a decade of experience in data science and machine learning, worked as a data scientist and data science manager at several startups, and holds a Master of Management in Artificial Intelligence from Queen's University. An as-told-to feature in Entrepreneur (Amanda Breen, June 22, 2026) dates that degree to 2019 and reports that he kept a full-time data science manager job until the end of 2025. His age and year of birth were not found in any public source reviewed.
He founded Prompt Advisers in late 2022, days after ChatGPT launched, initially selling prompt-writing services, including through Fiverr. The company's about page lists Taha El Harti as co-founder in charge of building AI systems. In the Entrepreneur feature, Kashef states that the business crossed $1 million in revenue in 2025, expects $1.5 to $2 million in 2026 and is split roughly 70% consulting and education and 30% custom development; these figures come from him and have no independent verification.
He publishes weekly videos on his YouTube channel, which showed 83.8K subscribers, 221 videos and Canada as the channel country when read on September 13, 2026 (joined March 14, 2023). He is also active on LinkedIn and X. Microsoft Learn lists him on its "Learn with" creator page.
His main paid education product is Early AI-dopters, a Skool community. Its official Skool page, read on September 13, 2026, showed a price of $43/month, about 1.3k members and 18 admins, and listed a Claude Code & Codex living course, a local and open-source AI course, n8n, vibe coding and voice-agent training, an AI consulting playbook, bookable 1:1 coaching, weekly live sessions and hackathons. Third-party review sites quoted $77/month earlier in 2026, so the price has changed over time. He also teaches paid live courses on O'Reilly, such as "Claude Code for Everyone", accessed through an O'Reilly subscription. Consulting through Prompt Advisers is quoted privately: his website points to email and a rate card, and the company offers a free 15-minute AI audit call. In the Entrepreneur feature he mentioned prompt engineering packages from $2,500 for small businesses, $15,000 to $50,000+ for enterprises and $8,000/month retainers; those figures are not published on an official price page.
On reputation: his coverage located consists of the Entrepreneur feature and podcast or YouTube interviews. No FTC action under the name Kashef was found in a search of ftc.gov on September 13, 2026. A company-registry check on OpenCorporates could not be completed that day, so Prompt Advisers' legal entity and jurisdiction are not confirmed here.
