I help small companies validate product ideas and build reliable software.

Shipping software requires multiple skill sets, across research, design, and development. When your time and budget are limited, you need to focus on high-leverage work that delivers value quickly. You need to get your product out there so that you can learn from your users and start iterating.

I work with startups and small teams to launch new apps and grow existing products. My experience with full-stack development and product management means I can support you through the entire project lifecycle. I'll help you design a minimum viable product that will allow you to ship quickly and learn about your market. And when your needs grow, I can help you find, hire, and train great employees.

If you're looking to get your software project launched or unstuck, I would love to talk. We'd start with a brief call to discuss your vision and see if we might be a good fit for each other. If you'd like to set up an introductory chat, email me at hello@kofigumbs.com.
