Frequently Asked Questions
Find quick answers to the most common questions about our services, process and collaboration.
Two things. Client work — websites, mobile apps and UI/UX for businesses — and our own trading products, Nexa Flux for crypto and Nexa Quant for Indian markets. The same engineering team works across both, which is why our client builds tend to be more performance-obsessed than most agency work.
A marketing website runs 3 to 5 weeks. A web application or mobile app is usually 8 to 14 weeks depending on scope. Strategy onboarding for Nexa Flux or Nexa Quant takes 2 to 4 weeks including backtesting and a paper-trading window. You get a dated milestone plan before we start.
AngelOne, Dhan, Fyers, Upstox and Zerodha, through their official APIs. You create the API keys on your own broker account and we configure them — your funds never leave your broker.
No. Nexa Flux and Nexa Quant are software. Orders are placed into your own broker or exchange account using your own API keys, and you can revoke those keys at any time.
Through PayU, which supports UPI, net banking, credit and debit cards, EMI and wallets. On the payment page, choose your plan, enter the amount and apply a discount code if you have one. You are redirected to PayU's secure page to complete the payment.
Most of our clients are elsewhere — Delhi NCR, Bengaluru, Mumbai and a few overseas. Work runs on a shared board with weekly calls, so distance makes very little difference.
