We are Sphyrna Solutions
A team specialised in autonomous AI agents with LangGraph. Python + FastAPI + RAG. No hype, real code.
Our story
We have worked with Python, APIs and backend systems for years. When we started exploring LLMs in 2023, we realised that most "AI solutions" were glorified chatbots with no real ability to reason.
Then we found LangGraph and everything changed: at last we could build agents that make decisions, look up contextual information with RAG, and adapt dynamically. Not if/else scripts dressed up as AI.
Since then we have specialised in cases that need complex reasoning: customer service that escalates intelligently, sales that qualify leads with context, operations that orchestrate multi-step decisions.
Our approach: fast prototypes (1-2 weeks), full transparency (we tell you if it does not apply), and real metrics (no magic promises).
Tech stack
Tools we master and use in every project
Core Stack
- Python (advanced): clean code, type hints
- LangGraph: state machines for complex agents
- LangChain: tools, memory, prompts
- FastAPI: asynchronous, scalable REST APIs
RAG & vectors
- Weaviate: main vector database
- OpenAI / Cohere embeddings
- Semantic chunking and reranking
- Retrieval optimization (recall + precision)
Infrastructure
- Docker + docker-compose
- PostgreSQL / MongoDB depending on the case
- Redis / RabbitMQ for queues
- Railway / Render for deployment

How we work
Non-negotiable principles in every project
Brutal honesty
If your case isn't a fit for an AI agent, we'll tell you. We'd rather lose a project than sell you hype.
Code over slides
Working prototypes fast. No PowerPoints or mockups: real Python code you can try.
Measurable results
If we can't measure the impact, there's no point. A metrics dashboard from day one.
Constant iteration
Agents improve with real feedback. A continuous process, not a finished project left to gather dust.
What we are NOT (important to read)
To avoid misunderstandings, this is what we explicitly are NOT:
We're not a big agency
We're a small, specialised team. We don't have 20 developers. Direct contact, no middlemen.
We don't do every kind of AI
We don't do model fine-tuning, computer vision or classic ML. Only autonomous agents with LLMs.
We don't take on just any project
If you need something urgent in 2 days, or a basic chatbot, there are better options. We work on complex cases that require reasoning.
We don't promise magic ROI
We don't sell a guaranteed 80% cost saving. We show realistic metrics based on similar cases.
Shall we talk about your project?
Tell us about your case. If it fits the way we work, we will give you a free analysis. If not, we will give you honest alternatives.
We reply within 24 hours. No commitment.
