There's no single "best stack" for a startup. There's only the best stack for this product, this team and this timeline.
At Divtechnosoft, a product and AI development agency in Ahmedabad, India, we build MVPs, SaaS platforms and mobile apps for founders around the world. After working with 50+ founders, one pattern stands out: the products that succeed are the ones where the technology choices match the problem, not the ones on the trendiest stack.
Here are six products we've shipped, the stack behind each, and the lesson each one taught us.
1. Summon: digital valet parking
What it is: A QR-based, paperless valet platform for hotels, hospitals, restaurants and multi-location enterprises. Stack: Ionic, Capacitor, Firebase, Stripe
Summon grew from 100 to 450+ locations, a 4.5x scale-up in 18 months. It has issued 158K+ tickets and passed $10K+ MRR.
Lesson: When the product is about real-time coordination between guests, attendants and managers, a managed real-time backend lets you ship fast and scale without rebuilding.
2. Ringlyn: voice AI for business calls
What it is: A human-like voice AI that handles business calls, qualifies leads and books appointments. Stack: Next.js, Supabase, Twilio, OpenAI
Ringlyn went to production in 19 weeks and handles 10,000 automated calls a month.
Lesson: AI products live or die on integration. The model is one piece. Telephony, data and workflows around it are what make it useful.
3. Unyted: multi-role EdTech
What it is: An education platform for students, parents and instructors, with live classes, a video library and progress tracking. Stack: Expo, Next.js, Socket.io
Lesson: When three different user roles share one product, design each role's experience separately, then build on shared foundations. Real-time features like live classes need real-time infrastructure from day one.
4. Mendo: civic data analytics
What it is: A platform that tracks footfall, turnover and sector performance for Norwegian municipalities. Stack: Laravel, Vue.js, MySQL
Mendo serves 20+ municipalities and made reporting 60% faster.
Lesson: Not everything needs the newest framework. For data-heavy, reporting-focused products, a proven, stable stack is often the smartest choice.
5. Momentum One: gym management SaaS
What it is: A multi-tenant SaaS that manages facilities, trainers, schedules and member access. Stack: Next.js, Supabase, Expo
Lesson: If you're building SaaS for many businesses, design for multi-tenancy from the start. Retrofitting tenant separation later is one of the most expensive mistakes in SaaS.
6. BrokerBuddy: real estate CRM
What it is: A multi-tenant CRM for listings, automatic lead matching and team management, on both web and mobile. Stack: Next.js, React Native, Supabase
BrokerBuddy was built in 16 weeks.
Lesson: Pairing Next.js on the web with React Native on mobile lets teams share knowledge and logic across platforms. It's a big advantage when a small team has to ship both.
The patterns across all six
Looking back across these builds, a few principles keep repeating:
Match the stack to the problem. Ionic and Firebase suited real-time valet. Laravel and Vue suited civic reporting. Next.js and Supabase suited multi-tenant SaaS. Different problems, different tools.
Managed backends speed up MVPs. Firebase and Supabase appear again and again because they remove weeks of backend setup.
Plan for scale in the structure, not the infrastructure. Multi-tenancy, roles and permissions belong in the design from day one. Heavy infrastructure can wait.
Real timelines are measured in weeks. Our case studies show 16 weeks for BrokerBuddy and 19 weeks to production for Ringlyn. A focused MVP should take months, not years.
Founders should own their code. At Divtechnosoft, code ownership transfers on milestone payment, with an NDA from day one. Whoever you build with, make sure you're never locked in.
Wrapping up
The right stack is the one that gets a real product in front of real users quickly, and keeps working as the business grows. That's what we aim for with every founder we work with.
