AI agents can't act in the physical world: no way to hire and coordinate real people for real-world tasks.

A polished, conversion-focused enterprise website driving consultation bookings, partnership inquiries, and product demo requests: the primary digital touchpoint for South Africa's leading HealthTech company.

Mainstay Digital

Interactive 3D product platform

Challenge

Complex B2B products are hard to explain: static slides and shipping thousand-pound demo units across continents slow deals and inflate costs.

Results

Higher engagement and faster decisions without the demo-shipping cost: 66% higher engagement, 15% faster decisions.
