our call
Start with LOVAT — highest vibe code, weakest moat.
LOVAT
Rebuilding the order aggregation dashboard and VAT threshold alerts takes less than a week with AI agents. However, LOVAT's core value is filing official returns directly with government tax portals across dozens of countries, which requires legal tax representation and specialized authorization. Building a dashboard is trivial; replacing the regulatory gateway is not.
