Looking to build an app like…
Pick a model to see how we’d build itKundli and horoscope engines, live astrologer consultations and per-minute billing, built to handle peak-hour demand and secure transactions.
Apps for the industries people use every day.
Rides, groceries, food, payments, health and learning. Each has its own rules, peaks and edge cases, and we have built for all of them.
AI that ships to production, not to a demo.
We build AI into the products and workflows you already run, with the evaluation, guardrails and cost controls that keep it trustworthy once real users arrive.
Chat and voice assistants inside your app or support desk, grounded in your own data and handing off to humans cleanly.
Search and answers across contracts, manuals and tickets, with sources shown so people can check the answer.
Agents that read, classify, route and act on invoices, emails and forms, with approval steps where it matters.
Classification, forecasting and recommendation models trained on your data when an off-the-shelf model is not enough.
Test sets, accuracy tracking, content filters and PII handling, so you know how it performs before and after launch.
Model selection, caching and hosting on AWS, Azure or GCP that keep per-request cost predictable at scale.
In the room with you.
Workshops before a line of code, demos every two weeks, and training so your team can run the app after launch.
A week with your team to agree what goes in version one and what it costs.
You see the app on your phone at the end of every sprint, not at the end of the project.
Your team learns to run, release and support the app before we step back.

Talk to a solution architect.
Not a sales rep. An architect reads your brief and replies within one business day. NDA available before the first call.
It depends on screens, integrations and platforms. After a short call we send a fixed-scope estimate with a range for each feature, so you can decide what goes into version one.
A focused first version usually takes 10 to 16 weeks after discovery, including backend, admin panel and store release.
Cross-platform suits most products and reaches both stores faster. We recommend native when the app depends on heavy device features or platform-specific performance.
Yes. We handle App Store and Play Store submission from your accounts, and the releases after it.
You do, from the first commit. Repositories, store accounts and infrastructure stay in your name.
