AI Agent Development Process
1
Discovery
- Vision Brief
- LLM Strategy
- Roadmap
We begin with a discovery session and brief focused on your core use case, startup roadmap, user base, and target workflows.
We help you select the right LLM platform (OpenAI, Azure, Claude, Llama2) and determine whether you need prompt-based agents or agentic chains.
From triggers and expected responses to fallbacks and actions, we map out the agent’s logic and architecture with startup-grade clarity.

Prompt Design
- Prompt Engineering
- Contextual Awareness
- Safety
We write and test base prompts, system instructions, tone control, and role definitions for predictable, accurate agent behavior.
For smart responses, we connect the agent to vector databases (RAG) or internal APIs so it can retrieve, summarize, and respond dynamically.
We add moderation, safety prompts, and behavioral boundaries to keep responses appropriate and within scope.

Test & Launch
- QA
- Deployment
- Analytics
We simulate hundreds of user prompts, test fallback states, and benchmark the agent’s understanding, tone, and performance.
Whether it’s embedded in your web app, admin panel, or standalone, we host and configure your AI agent for uptime, speed, and control.
Post-launch, we track usage, drop-offs, and feedback — giving you the insights needed to improve and scale your agent.
