Frequently Asked Questions
Do you have an office in San Francisco?
We do not have a San Francisco office. We serve Bay Area clients remotely from our India studio, coordinated through our US office in Kirkland, Washington. Our morning shift overlaps your West Coast start of day.
How does your pricing compare to hiring in the Bay Area?
Our AI-accelerated delivery starts around USD 20 per hour, far below Bay Area engineering salaries and agency rates, which lets early-stage teams stretch runway while keeping senior talent on the build.
Can you take a product from MVP to scale?
Yes. We start with a lean, investor-ready MVP and grow it into a production-grade platform as you raise and add users, keeping the same senior team on the codebase throughout.
How real is your AI/ML experience?
We ship LLM and generative AI features, RAG pipelines, chatbots and ML models in production using OpenAI and Python, not just demos. We scope AI work to measurable outcomes, not hype.
How do you handle IP, NDAs and data security?
We sign NDAs before sharing anything, assign full IP and source ownership to you, and follow ISO 9001:2015 controls with secure repositories, managed access and careful data-handling practices.
