frequently asked questions

Why work with an agile AI startup instead of a traditional software agency?

Traditional agencies carry bloated legacy overhead and slow processes. As a modern AI engineering startup, we are native to the new era of autonomous agents, foundation models, and vector architectures. You work directly with hands-on AI builders and founders — moving from idea to working AI MVP in 2 to 4 weeks with zero bureaucratic delays and flexible, startup-friendly pricing.

What AI solutions and products does Qubartech build?

We specialize in end-to-end AI engineering: Autonomous AI Multi-Agent Workflows (LangGraph, CrewAI), Zero-Hallucination Enterprise RAG over private knowledge bases, Custom LLM Fine-Tuning (Llama 3.3, DeepSeek, Mistral), Computer Vision & Document OCR Extraction (IDP), Predictive ML, and Full-Stack AI-Native Web & Mobile SaaS applications.

How do you protect our proprietary data and prevent AI training leakage?

Data confidentiality is our highest priority. We architect strictly isolated, zero-data-retention AI pipelines. When using commercial models (OpenAI, Anthropic, Gemini), we enforce enterprise zero-retention API policies. For sensitive healthcare (HIPAA), financial, or proprietary workflows, we deploy self-hosted models (Llama 3, DeepSeek) inside your private cloud VPC (AWS, GCP, Azure) with zero external data exposure.

How fast can we launch an AI MVP from concept to production?

We follow rapid agile sprints. An AI Proof of Concept (PoC) or initial MVP typically ships within 2 to 4 weeks. Full-scale multi-agent systems and private fine-tuned platforms are delivered and hardened for production in 4 to 8 weeks, complete with observability, CI/CD, and robust evaluation benchmarks.

What are your engagement models for startups and growing businesses?

We offer founder-friendly, transparent pricing: (1) Fixed-Scope AI MVP Sprints for fast launches, (2) Dedicated AI Engineering Pods (hands-on AI/ML engineers embedded with your team), and (3) Fractional AI CTO & Architecture consulting. Use our interactive AI Calculator on this page for instant estimates.

Do you provide post-launch AI monitoring, evaluation, and fine-tuning?

Yes! AI models require active observability. We integrate comprehensive telemetry, token usage tracking, latency monitoring, and automated eval suites (using tools like LangSmith and custom test harnesses) to ensure your AI maintains 99%+ accuracy as your data evolves.
