IV Varyvoda

I build products—and I keep them alive.

I’m Igor Varyvoda, a product builder and operator. I started with a profitable website that reached roughly 50,000 unique visitors a day, later ran developers and marketers across internet businesses, and now build Sirv Studio alongside a living portfolio of independent products.

Some for work, some because I can’t help myself.

Made in Ukraine. Based in Montenegro.

Sirv AI Studio

Sirv Studio AI batch creation interface

An AI product-content platform for e-commerce — I created it and built it end to end. Merchants scan their Shopify catalog, fix product content in AI batches, route supplier uploads through review, and publish safely with versioning and rollback.

I built a button that sends you somewhere unexpected, then added enough real travel data to make the result useful rather than merely random.
