255labs
255labs is two brothers, Martyn and Mikkel Garcia: senior engineers who have built software together since 2012 and now focus on AI. We build our own AI products, maintain open source like HyperGAN, co-run Differential AI Lab, and help startups design, build and ship AI agents, pipelines and MVPs.
LLM agents connected to your real systems and data, engineered with tool guardrails to hold up in production, not just in a demo.
AI agents →Proofs of concept, investor demos and first versions of your product, built directly by the two engineers you talk to.
MVP development →Data and inference pipelines, LoRA fine-tuning for LLMs and diffusion models, and the infrastructure to run them.
AI pipelines →Also: rapid prototyping, APIs & integrations, architecture, DevOps and ML infrastructure.
Products, research labs and platforms we built and run ourselves.
Our four-person applied AI research and consulting lab with Gabe and Lee: AI software factories, organizational AI transformation, and agentic boundary enforcement.
AI-powered executive decision-making for SMBs and startups. Generate custom AI executives tailored to your business.
Backdrop Build V4, V5 & V6 finalist
Create text-to-image LoRAs from words alone, no dataset required, or merge LoRAs together. Over 1,000 LoRAs and DoRAs trained, with more than 5 million uses and downloads.
A collection of apps on the Wix platform that we have built, supported and maintained for over a decade.
Serves thousands of businesses
A choose-your-own-adventure story project with huge amounts of AI-generated content. We engineered the inference to scale to massive levels of interactive content.
An unlimited stream of AI-generated music, from lyrics to finished songs.
Add actions to your custom GPTs. Create APIs or use ones that others have built.
Backdrop Build V2 finalist
Create a course on anything using AI. Built with Amazon Bedrock and Anthropic Claude.
Denver Startup Week 2023 hackathon winner
An NFT collectible card game on the NEAR blockchain, with open source Rust contracts.
BOSHacks 2023, 2nd place

Our open source lives in five GitHub organizations: 255BITS (our company account; 255labs is our trade name), HyperGAN, Differential AI Lab (difflab.ai) (which we run with Gabe and Lee), nanoodle (nanoodle.com), and NTCAI (ntcai.xyz), plus a few more on our personal accounts. Stars and activity come straight from GitHub.
