Frequently Asked Questions

Everything you need to know about working with Sigma Intelligence

Most projects range from $40k-100k for the first year, with a total 3-year cost of $100-250k. That's significantly cheaper than building in-house ($800k-1M) while delivering 100% custom solutions vs generic SaaS ($150-200k). We provide detailed ROI projections during your free consultation.

We deliver your first working prototype in 48 hours, and most systems go live within 4-8 weeks. Compare that to 6-12 months for building in-house or the 12+ months it takes to see ROI from generic SaaS tools that don't fit your workflow.

Perfect! Most of our clients aren't technical. We explain everything in plain English, handle all the technical complexity, and train your team to use the systems. You focus on your businessβ€”we handle the AI engineering.

Yes, 100%. Unlike SaaS where you're renting access, you own everything we build. It runs on your infrastructure, you control your data, and there's no vendor lock-in. You can take it anywhere.

Our clients typically see ROI within 2-3 months. Common results: 40+ hours/week saved on manual tasks, 24/7 customer response, real-time business insights, and processes that scale without hiring. Every project includes measurable KPIs so you can track impact.

Unlike hiring an in-house team (expensive 24/7 coverage) or SaaS support (ticket system only), you get dedicated direct access to our engineering team for maintenance, updates, and enhancements. We're your long-term AI partner.
