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.

La Crown Inc. is an AI automation agency founded by a 26-year freight brokerage veteran who got tired of watching businesses drown in repetitive tasks. We specialize in building voice AI systems powered by Retell AI — intelligent agents that handle carrier calls, customer follow-ups, compliance checks, and lead outreach around the clock. We don't just deploy AI; we engineer it around the real workflows of freight brokers, logistics operators, and business owners so it actually works on day one.
