SaaS Development Agency: From Idea to 50,000 Conversions
We don't just build SaaS products — we built our own. VectoSolve serves 120 countries with 50,000+ conversions. We bring that same product thinking, technical rigor, and growth mindset to your SaaS.
Building a SaaS is harder than you think
Most SaaS projects fail not because of the idea, but because of poor execution. Agencies without SaaS experience underestimate the complexity of multi-tenancy, subscription billing, usage tracking, and onboarding flows. You end up with a prototype that can't scale.
Battle-tested SaaS architecture from day one
Multi-Tenant Architecture
Proper data isolation with Supabase Row Level Security, organization management, team invitations, and role-based access control built in from the start.
Stripe Subscription Billing
Complete billing system with free trials, multiple plans, usage-based pricing, proration, invoicing, and self-service plan management.
User Onboarding Flows
Guided setup wizards, progressive profiling, and activation checklists designed to convert free users into paying customers.
Admin Dashboard
Real-time metrics on MRR, churn, active users, and feature adoption. Export data, manage customers, and monitor system health from one place.
API & Integrations
REST or GraphQL API for third-party integrations, webhooks for event-driven workflows, and OAuth for marketplace listings.
Scalable Infrastructure
Next.js on Vercel with Supabase handles thousands of concurrent users. Horizontal scaling, connection pooling, and edge caching keep performance consistent as you grow.

We use Next.js for the frontend and API layer, Supabase for the database and authentication, Stripe for billing, and Vercel for deployment. This stack lets us move fast while maintaining production-grade reliability and scalability.
A focused MVP with 3 to 5 core features typically launches in 6 to 8 weeks. We prioritize features that validate your business hypothesis and generate revenue, deferring nice-to-haves to post-launch iterations.
Both. Having built our own SaaS from zero to 50,000 conversions, we bring product thinking to every engagement. We help prioritize features, design onboarding flows, and plan pricing strategies based on real experience.
We offer ongoing development support with flexible monthly retainers. Most clients start with our Growth package for continued feature development, performance optimization, and scaling support as their user base grows.
Yes. We start with a product discovery workshop to define your user personas, core jobs-to-be-done, and feature priorities. We then produce wireframes and a technical spec before writing any code, so you know exactly what you're getting.
