Expertise:

We Know Code.

Whether you're still experimenting or have found product-market fit, our developers have the experience & expertise to accelerate your engineering output.

Prototyping & MVPs

Don't waste valuable time and money building the wrong thing. Focus is a skill, and we'll help you rapidly test your concept with interactive prototypes, gather user feedback, and de-risk your launch. Your code is guaranteed to work so if something breaks after our contract ends, we will gladly fix it.

Custom Development

We specialize in creating custom applications that are designed to meet your specific requirements and objectives, including MVPs and prototypes, with your customers in mind. Our team is happy to join your customer conversations for a better understanding of the problem.

AI-Enhanced Solutions

We modernize your business with tailored AI solutions powered by leading closed and open-source large language models (GPT, Claude, Llama). Automate tasks, gain data insights, and enhance capabilities with adaptive systems designed specifically for your needs.

Staff Augmentation

Need additional engineering resources that plug seamlessly into your systems and processes? We can provide skilled engineers to augment your team with on-shore and off-shore talent, including options to recruit full-time engineers for your team.

Founding Engineers

Avoid costly hiring mistakes with our Founding Engineers service. Horizon Labs sources, trains, and manages top-tier product developers—handling oversight and delivery for up to 1,000 hours—allowing startups to confidently hire proven talent when they're ready.

Other?

We are great coders. For everything else, we make introductions with people we've worked with. Tell us what you need and we'll be happy to recommend someone from our network of incubators, accelerators, investors, and advisors to get your non-code related problems solved!
