Sostratus creates knowledge products delivered as native digital apps — not course links, not PDFs, not generic platforms. Each offer is a real product, with its own identity, domain, and experience.
The infoproduct industry hasn't changed its delivery format in decades. We're changing that.
Sostratus identifies market opportunities, builds the offer, engineers the app, and takes it to market — all under its own portfolio.
We research validated markets where knowledge delivery can be radically improved by a native app experience.
We design the content, structure, and value proposition for each product — from scratch, with intention.
Each offer is delivered as a branded app on its own domain — not a template, a real product experience.
VSL → purchase → instant access. A clean acquisition funnel that converts and retains.
Every Sostratus offer ships as a fully engineered digital product — with the infrastructure an audience expects from a real app.
Each offer has its own domain and visual identity — completely independent from any third-party platform.
Content organized as a real app — modules, progress, access levels — not a folder of files.
Purchase-gated access with annual licensing. Exclusive content that stays valuable over time.
One-time payment, instant access, annual license. A frictionless buying experience for every customer.
Multi-language support built in. Every product is designed to reach global audiences from day one.
Deployed on global CDN infrastructure. Every product is fast everywhere and available always.
SOSTRATUS · Named after Sostratos of Cnidos, architect of the Lighthouse of Alexandria, one of the Seven Wonders of the Ancient World.
Each offer is an independent infoapp — its own brand, its own domain, its own audience. Purchases are processed on each product's domain under the Sostratus account.
