FAQ
What types of projects does Superscript specialize in?
We build and maintain the software behind complex money movement: payment integrations, multi-party payouts, KYC flows, and agentic AI for financial operations with human-in-the-loop controls.
What is a Payment Architecture Review?
A fixed-fee, three-week assessment of your payment stack or planned build: integration architecture, payout logic, failure modes, reconciliation gaps, and where agentic automation is safe to add. You leave with a written roadmap you can execute with us or without us.
How does your process ensure quality and reliability?
Every project follows a proven development process with source control, CI/CD, automated testing, and professional QA to ensure stability and scalability.
Are you SOC 2 compliant?
Yes - Superscript is SOC 2 compliant, with security controls and processes in place to protect customer data (access controls, change management, monitoring, incident response). We can share relevant compliance documentation under NDA if needed.
How quickly can you start a new project?
We can typically start within 2–3 weeks after initial discovery. Our process allows us to assemble the right team and begin delivering results fast - without compromising quality.
What makes Superscript different from other dev shops?
Dedicated teams that work together on your product. We build complete platforms end-to-end - not staff augmentation.
What companies do you work with?
We work best with mid-sized companies ($10M-$250M revenue) that need a dedicated development team for 6-18 month projects.
