FAQ · San Francisco

Questions from teams in San Francisco.

Something we haven't covered? Write to info@kurchu.com — a senior person replies within one working day.

Yes, remotely from Lahore, Pakistan. An 8:00–10:00 call in San Francisco is 21:00–23:00 in Lahore in winter and 20:00–22:00 in summer, after which we keep building while you sleep. For a startup that turns a 24-hour clock into a feature: you review in the morning, we ship overnight, and the loop runs every day.

With us, focused MVPs typically start in the mid five figures, while full platforms with several apps and an admin panel run into six. If your MVP includes AI features, budget for ongoing model usage as well as the build — we set per-user cost caps and choose between hosted and on-device models so usage costs stay predictable. The first phase is a fixed USD price, agreed after a short discovery call.

Yes. We build features such as chat assistants, search over your own content, summarisation and image understanding, using hosted models from OpenAI or Anthropic, or on-device models when privacy or cost matters. We design for failure too: rate limits, fallbacks, cost caps and evaluation tests, so the feature behaves predictably for real users, not just in a demo.

Most MVPs take 12–16 weeks from discovery to store launch. If a raise is planned, we work back from the date: the first installable build arrives early, analytics are in from the first release, and the scope is cut to what proves your core metric. Investors see a live product with real usage data, not a prototype.
