Founder · Repath ‘Ray’ Khan
One founder.
Many models.
One mission.
Repath Khan — publicly credited as “Ray” on most posts — is the Waterford-based founder of the Leemer Group. He started LeemerChat in 2023 as a resilience layer against model outages. Three years later it is a full workspace, an infrastructure company, a custom-model foundry, an agentic platform, and a code review product.

Short bio
Repath studied at the University of Limerick and founded Repath Enterprises Ltd before incubating LeemerChat. He is deliberately an Ireland-based builder: LeemerLabs operates out of Waterford with failover in Dublin, and almost all engineering decisions are made with European compliance posture as a non-negotiable input.
He is not a “prompt engineer” founder. Since LLaMA-1 he has fine-tuned Qwen, LLaMA, Gemma, Mistral, Mixtral, and a list of smaller models; built bilingual Bengali/English distillations; and designed orchestrator → worker chains inside LeemerChat before agents were fashionable. He tends to talk about models from the inside.
The through-line across everything he ships is the same argument: a single opaque API is the wrong abstraction for serious work, coordination beats raw scale, and open weights inside a European stack are how real organisations should operate. LeemerLabs is that argument, made as infrastructure.
In his own words
“The future of AI is not a single super-intelligence. It is systems that coordinate intelligence well.”
“If an AI system cannot reason reliably without tools, giving it tools will not make it safer. It will just make it louder.”
“Your data. Your model. Our GPUs. Built in Waterford, scaling globally.”
“We eat our own cooking. Every system we offer a client, we've already built for ourselves.”
What he's built
Seven shipped products.
Not a roadmap. Not a pitch deck. A list of products that have processed real user traffic — typically before the rest of the market knew they were supposed to exist.
01
LeemerChat
2023 — present
The flagship multi-model workspace. Over 1B tokens processed through real user traffic. Codebase chat, background agents, PDF/research flows, 50+ models.
02
LeemerLabs
2025 — present
The research and infrastructure arm. Hosts the public inference gateway, Model Foundry, and the engineering behind everything the Leemer Group ships.
03
KingLeemer
2026
Multi-model consensus protocol. V1 reasoning council, V2 autonomous tool loops. The argument that coordination beats a bigger model.
04
Mission Control
2026
Agentic execution platform. "Drop a mission. Get intelligence." Cortex orchestrator, sandboxed workers, artifact-first output.
05
Critique.sh
2026
GitHub-native AI code review built on a sandbox-native architecture. Newest product in the Group.
06
Foundry
2025 — present
Custom LLM studio. Ireland's first Tinker partner. Fine-tunes 1B → 235B MoE models with exportable weights.
07
Warren.wiki · ExamMate · HeyCouncil · DeepThis
2024 — present
Domain-specific deployments in finance, education, civic, and research — built on the same infrastructure sold to clients.
Timeline
Shipping since 2023.
2023
LeemerChat starts as a resilience layer against model outages — a backup for when GPT-4 went down. Turns into something bigger.
2024
Workspace era. Research mode, writer, podcast flows, sharing. The product becomes a daily driver.
2025
Sprint year. v4.5 research and automation, v4.8 durable generation, LeemerLite on Groq, v4.9 PowerCode + LeemerGLM. November: LeemerLabs Model Foundry launches. Ireland's first Tinker beta partner.
2026
KingLeemer (Feb). Blackbox + Cursor Cloud integrations (Feb). Tinker goes GA, Foundry Report publishes (Feb). Mission Control (Mar). Critique.sh releases v3.1 on a 48-hour cadence. LeemerLabs opens its public inference gateway.
