About Railsware

Railsware is a product development agency and AI-accelerated software consultancy, founded in 2007 and now roughly 200 people across the globe. We help funded startups and growth-stage companies design, build, and scale web and mobile products – from fixed-scope AI-driven MVPs to full product teams in a long-term cooperation. Our services span AI-Driven MVP Development, AI Integration for existing products, stabilization of AI-generated (""vibe coded"") codebases, and full-stack development from ideation through scale. Alongside client work, we build and maintain our own SaaS products with millions of users – Mailtrap, Coupler.io, and TitanApps. It keeps our engineering judgment grounded in products we ship and support ourselves, not just deliver and hand off. Notable client work includes Calendly, taken from early-stage through to unicorn status, along with BrightBytes, TradeZella, ParentSquare, and Seedtime.
