I build web platforms, mobile apps and AI products for U.S. companies, from the first spec to production and beyond. I'm Alex Polchert, co-founder of Imajine. For over a decade my team and I have shipped SaaS products, marketplaces, healthcare platforms and fintech apps used by millions of users across the U.S. When a product also needs connected hardware, we build that too.
