Frequently Asked Questions
How long does it take to build a SaaS application?
A SaaS MVP with core subscription features typically takes 10–14 weeks. A full-featured SaaS platform with all integrations and enterprise features takes 20–30 weeks. We break development into phases so you can launch and start getting paid earlier while we continue building.
Do you handle the cloud infrastructure and DevOps?
Yes. We set up complete cloud infrastructure on AWS or GCP — including auto-scaling, database backups, CDN, SSL, and monitoring. We also configure CI/CD pipelines so every code change is automatically tested and deployed safely.
Can you add AI features to my SaaS product?
Yes. We integrate OpenAI GPT, Claude, or open-source models into SaaS products for features like AI-powered search, content generation, smart recommendations, classification, and NLP-based workflows. We've built multiple AI-enhanced SaaS products.
Will my SaaS be GDPR compliant?
Yes. GDPR compliance is built into our SaaS development process — including data deletion workflows, privacy policy integration, cookie consent, data export, DPA agreements, and audit logging. We can also assist with SOC 2 preparation for enterprise SaaS.
Do you offer equity-for-development arrangements?
We consider equity arrangements case-by-case for very early-stage startups with strong fundamentals. Contact us with your pitch deck and we can discuss a hybrid cash + equity model. We also offer milestone-based billing to ease cash flow pressure.
