Shir Krivinsky, Founder

Shir Krivinsky is the founder of Opti-Fuse and a full-stack developer who builds small businesses their own AI video, SEO and email marketing systems. He built and still runs his own video operation: a faceless video engine that publishes to 17 content channels across YouTube, TikTok, Instagram, Facebook, X and Threads, plus a pipeline that generates ad videos featuring five AI personas on a daily schedule. He has worked in sales since 2006 and in pay-per-call lead generation since 2013, so he builds video to bring in calls and customers, not just views. He is based in Altamonte Springs, Florida.

• Every guide answers a real question small-business owners ask, starting with a direct answer.
• Guides are researched and drafted with AI, then checked: any statistic or claim about the wider world must link to a named source, and anything about our own product must match our published facts.
• We never promise rankings, AI citations or specific results, never invent customers or testimonials, and never name competitors.
• Guides are reviewed and refreshed as tools and platforms change; the “Updated” date shows the last review.
