We design, build, and run AI systems that take real work off your team — agents that handle support and operations, voice agents that answer the phone, and LLM features wired into the tools you already use. Small senior team, production from week one.
Agents that take over the repetitive work — triaging inboxes, qualifying leads, updating the CRM, reconciling data — with a human in the loop where it matters.
Phone agents that answer every call, book appointments, and resolve support questions in natural conversation — built on Retell AI, Vapi, Twilio, or LiveKit.
Search, assistants, document extraction, and copilots added to your product or internal tools — with evals, guardrails, and cost control from day one.
Not sure where AI fits? We map your processes, find the few places it pays off fastest, and hand you a costed plan you can run with us or without us.
Customer calls queued across time zones and the support team was stretched thin. We built a multi-language voice agent that answers instantly, resolves common requests, and logs every call into Salesforce. Wait times dropped by 90% and the team now focuses on the cases that need a human.
A geo-targeted platform built on autonomous agents. We engineered product surfaces on top of the agent layer and shipped them to production, where they run today.
Ads automation for koast.ai — agent-driven tooling that takes repetitive campaign work off the team, so their time goes to strategy instead of dashboards.
A multi-agent system that reads screenshots of inbound messages, checks a wallet's history, and flags scams before the user acts — combining OCR, heuristics, and LLM reasoning. Won Best AI Agent at ETHGlobal Bangkok.
We sit with your team, map the workflow, and agree on the one metric that proves it worked.
A working version on your real data, fast — so you judge results, not slide decks.
Production hardening: integrations, evals, guardrails, monitoring, and handover docs.
We watch the numbers, tune prompts and models, and extend the system as your needs grow.
Tell us what's slowing your team down. We'll tell you honestly whether AI is the right fix and what it would take.
We review your processes and systems, identify the highest-return AI opportunities, and deliver a costed roadmap.
One AI system taken from idea to production — an agent, a voice agent, or an LLM feature — integrated with your stack.
We run and improve your AI systems, ship new automations, and act as your senior AI team on call.
