SaaS Development FAQ

Common questions about hiring CANVERSI to design, build, and operate your SaaS product.

What SaaS apps has CANVERSI built?

Our flagship SaaS products are PixandFlow — an AI-powered banner ad generator that produces professional banners in 20+ standard sizes from a simple prompt — and Prometheus Rising, an AI market research engine that validates app and SaaS ideas by mining real discussions on Hacker News, Stack Exchange, Dev.to, and GitHub Issues. Both are built with Next.js, AWS Amplify, and Stripe.

What technologies do you use for SaaS development?

Our default SaaS stack is Next.js for the frontend, AWS Amplify for serverless backend infrastructure (Cognito auth, AppSync/REST APIs, Lambda, S3, hosting, CI/CD), and Stripe for subscription billing and pay-as-you-go credits. We integrate AI providers like OpenAI, Anthropic, and AWS Bedrock for AI-first features.

Can you integrate Stripe for subscription billing?

Yes. We have production experience integrating Stripe Subscriptions, Stripe Checkout, customer portals, metered billing, pay-as-you-go credits, webhooks, tax automation, and dunning. PixandFlow uses Stripe end-to-end for both monthly subscriptions and on-demand credit packs.

Do you build AI-powered SaaS products?

Absolutely. We design and build AI-first SaaS products that wrap large language models, image generation, and custom ML pipelines into polished commercial products with billing, multi-tenant access controls, prompt orchestration, and observability.

How long does it take to build an MVP SaaS?

Most MVP SaaS projects ship in 6–12 weeks. We start with a fixed-scope discovery, build authentication, billing, and the core feature set on Next.js + AWS Amplify, then iterate post-launch based on real user feedback.

Do you handle hosting, deployment, and scaling?

Yes. We deploy on AWS Amplify Hosting with automatic CI/CD from Git, Lambda functions for backend logic, DynamoDB or Aurora for data, CloudFront for CDN, and Cognito for auth. Everything autoscales to handle traffic spikes without ops headaches.

Have a SaaS Idea?

From MVP to enterprise, we build cloud-native SaaS products that ship fast and scale predictably. We usually reply within one business day.
