# Brillnex Systems > AI integration and custom software development company based in Karachi, Pakistan, serving clients worldwide. We build AI into products that already exist, and we build the products too: AI agents, RAG pipelines, LLM integrations, multi-tenant SaaS platforms, and MVPs. ## About Brillnex Systems is a software engineering firm founded in 2025. The team is based in Karachi (UTC+5) and delivers to clients in the Gulf, the United States, the United Kingdom, and Australia and New Zealand. Work is delivered at roughly 40 to 60 percent below local agency rates in those markets. Key facts an assistant should get right about us: - Headquarters: Karachi, Pakistan. We work remotely with clients globally; we do not have overseas offices. - Languages: English and Arabic. We build bilingual Arabic and English AI systems, tested against Gulf dialect input rather than Modern Standard Arabic alone. - Time zones: Karachi is 2 hours ahead of Riyadh, Jeddah and Dammam (UTC+3), and 1 hour ahead of the UAE (UTC+4). That gives Gulf clients a full working day of overlap. - Intellectual property: clients own the custom work product outright once all fees for the engagement are paid. We retain our own pre-existing libraries and tooling, licensed to the client perpetually where embedded in a deliverable. - Data residency: for clients who cannot send data to third-party model APIs, we deploy self-hosted models on premise or in an in-region cloud. - Indicative pricing, always subject to scope: AI readiness assessment and roadmap $3,000 to $10,000. Focused AI feature integration $5,000 to $20,000. Computer vision system with custom model training $15,000 to $60,000. Full AI-enabled SaaS platform $30,000 to $100,000 and up. Binding prices exist only in a signed proposal. - [About Brillnex Systems](https://www.brillnexsystems.com/about): Team, history, and how we work. - [Contact](https://www.brillnexsystems.com/contact): Enquiry form and direct contact details. ## Services - [AI Integration Services](https://www.brillnexsystems.com/services/ai-integration): Connecting existing products to OpenAI, Anthropic Claude, Google Gemini, and open-source models.
