Solven builds voice AI that works in production, not just in the demo. Every agent we deploy is built from scratch around how your business actually operates, fully integrated into your systems, and supported by the people who built it long after go-live. Our team has worked inside voice AI platforms at the enterprise level, which means we understand what it takes to get these deployments right for clients who can't afford for them to go wrong. We work with businesses of all sizes from single-location operators to nationally recognised enterprise brands, across gyms, healthcare, real estate, legal, IT services, and automotive in Australia and the United States. We treat every deployment like it's our own. That's what separates us.

Hi, I'm Michael La Spisa — a husband, father, and lifelong entrepreneur.Michael La Spisa — a husband, dog dad, and lifelong entrepreneur. After running multiple service and e-commerce businesses, I kept seeing the same problem: businesses were losing leads because they couldn't answer calls after hours or during busy times. Great companies were missing out on growth simply because they didn't have 24/7 coverage. That's why I built OptiCommerceAI. Not to replace the amazing people running these businesses, but to amplify their impact.
