Calda

What Calda does

Calda is an AI-native app development studio founded in 2022 in Ljubljana, Slovenia by Anže Šterbenc (CEO) and Nikola Nedić. The company designs, builds, and ships mobile and web applications for enterprise clients (notably Subway, with 37,000+ global locations) and startups across verticals including sports, finance, real estate, social, and lifestyle. Its core technology stack centers on FlutterFlow for rapid cross-platform development and Supabase for backend infrastructure, supplemented by Firebase, Stripe, and AWS integrations.

The business operates a professional services model with two pricing structures: fixed-price multi-year project engagements for clearly scoped work, and monthly hourly retainers for ongoing development and maintenance. Beyond client services, Calda has productized its own consumer and vertical applications — including PitchSafe (sports tech), Superplan (AI financial advisory), Client Keeper (real estate CRM), WildSound (lifestyle audio), MobioT (vehicle GPS), and Superdex (automotive social) — using the same FlutterFlow/Supabase stack. It also runs an AI Consulting & Engineering practice focused on AI transformation, data engineering, and agentic product development.

Calda has scaled to approximately 35 employees and reports "several million euros" in cumulative revenue over three years of operation. It holds a New York office alongside its Ljubljana headquarters, and has earned consecutive FlutterFlow Agency of the Year (2025, 2026) and App Design of the Year (2024, 2025) awards, plus Top 4 Featured Supabase Experts status. Strategic platform partnerships with FlutterFlow, Supabase, Stripe, Expo, and OpenAI (joined July 2026) anchor its go-to-market, with a 4.9 Clutch rating and 5.0 FlutterFlow platform rating serving as primary credibility signals for inbound enterprise and mid-market demand.
