As answered by people managing DevFinanceTools and Raviga.io.
Raviga.io's answer:
Raviga is built by a working performer who experienced the admin frustrations first-hand. Unlike generic CRM tools adapted for entertainers, Raviga is designed from the ground up for how UK performers actually run their businesses, with native VAT support, GBP pricing, and workflows that match the reality of managing gigs, not corporate sales pipelines.
Raviga.io's answer:
Raviga offers a modern, mobile-responsive interface at a lower price point than established competitors like Giggio and DJ Manager (£15/month vs £25/month). It includes a genuinely usable free tier with up to 5 events, not a limited trial. The platform covers the complete client journey from enquiry to payment in one place, with digital contract signing, automated emails, and payment tracking built in.
Raviga.io's answer:
UK-based entertainment professionals who run their own bookings, including mobile DJs, musicians, bands, singers, magicians, children's entertainers, photobooth operators, and event suppliers. Typically solo performers or small teams managing anywhere from a handful of gigs to hundreds of events per year, who want to look professional and spend less time on admin.
Raviga.io's answer:
Raviga was built by a mobile DJ with 25 years of experience who got fed up running his business from spreadsheets and disconnected tools. After testing existing platforms and finding them either dated, overpriced, or designed for the US market, he built the platform he wished existed, during evenings and weekends over four months in 2025.
Raviga.io's answer:
Raviga is in early launch phase and doesn't publicly disclose individual customer names. Current users include mobile DJs, wedding entertainers, and event suppliers across the UK.
