AI, Web & Mobile App Development Agency — Nexa Innovations

We build AI agents and workflow automation, websites and web apps, native iOS and Android apps, and the backend and cloud infrastructure behind them. We also run SEO, digital marketing and Meta advertising, and handle product design and brand strategy. One team covers the whole thing, so nothing gets lost between agencies.

It depends on scope, but we quote a fixed price before starting rather than billing open-ended hours. Smaller projects typically start around $1,000–$3,000; full products and ongoing marketing retainers run higher. You get the number in writing after a free discovery call, with no obligation to proceed.

Most websites go live in 4–8 weeks and mobile apps in 8–12, depending on complexity. AI automation projects are often faster — many are running within 2–4 weeks. You see working progress from the first week rather than waiting for a reveal at the end.

Yes. We work with clients across the US, UK, UAE, Europe and Australia, and most of our projects are delivered remotely. We keep overlapping hours with your timezone for calls and stay reachable on email and WhatsApp in between.

You do. Code, designs and any ad or analytics accounts we set up are yours, transferred on final payment. We don't hold anything hostage — if you ever want to move on or bring the work in-house, everything goes with you.

An AI agent is software that handles a repetitive job end to end — answering support questions, qualifying leads, updating your CRM — using your own data and rules. It helps most when your team spends hours a week on the same task. On a free call we'll tell you honestly whether it's worth automating in your case.

Paid ads can bring leads within days once tracking and creative are right. SEO is slower and compounds: expect movement in 2–3 months and meaningful traffic by month 4–6. Anyone promising page one in weeks is selling something we wouldn't.

We stay on for the first month at no extra cost to fix anything that surfaces with real traffic. After that, ongoing support and maintenance is optional — some clients keep us on a retainer, others take it in-house with the documentation we hand over.
