Our approach
Five stages, paired end-to-end.
Predictable delivery. No black-box sprints.
01
Architect
Design real-time infrastructure — rooms, participants, tracks, and AI agent topology.
02
Build
Develop LiveKit agents with STT-LLM-TTS pipelines and custom business logic.
03
Integrate
Connect to your CRM, knowledge base, and telephony systems via SIP.
04
Deploy
Production deployment with auto-scaling, monitoring, and failover.
05
Optimise
Latency tuning, cost optimisation, and continuous agent improvement.
Customer value
Six places it pays back in the first sprint.
Real outcomes our clients report within the first engagement cycle.
Faster time-to-market
Production-ready teams that ship from week one — no ramp-up lag.
Reduced technical risk
Architecture reviews, code audits, and security scans baked into every sprint.
Measurable velocity
Cycle time, PR throughput, and defect density tracked from day one.
Cost predictability
Fixed-price or capped T&M — no surprise invoices, ever.
Continuous improvement
Retros, post-mortems, and process refinement every sprint.
Knowledge transfer
Your team grows. Documentation, pair programming, and workshops included.

Sub-Second AI Voice
Architecture
Our LiveKit integration services are built around a highly optimized STT-LLM-TTS pipeline. By combining best-in-class AI models over a low-latency WebRTC connection, we build AI agents that respond faster than humanly possible.
1. User Audio
User speaks into browser/app. Audio streams via LiveKit WebRTCat <50ms latency.
2. STT Engine
Streaming Speech-to-Text (e.g., Deepgram) converts audio to text instantly.
3. LLM Logic
LiveKit Agents SDK processes context and streams text responses via OpenAI / Claude.
4. TTS Engine
Text is synthesized into ultra-realistic voice (ElevenLabs) and streamed back.
