Frequently Asked Questions
Common questions from California companies before a first call.
How much do software development services in California cost?

Larger platforms with integrations and compliance requirements usually range from $120,000 to $400,000. After the free call, we give you a written estimate with a range for each phase.

Our engineers are based in the US and work Pacific Time hours. For discovery workshops and launches, we meet on-site in the Bay Area, Los Angeles and San Diego.

How long does it take to build an MVP or a mobile app?

Do you build software that complies with HIPAA and the CCPA?

Do you offer AI and generative AI development in California?
Yes. We build AI agents, chatbots, voice agents, document processing and predictive models, connect them to your existing data, and plan for California bot disclosure and AI transparency rules.
What makes TechRev a different software development company in California?
