appendTo is owned and operated by DevelopIntelligence. DevelopIntelligence was founded in 2003 and we’ve trained 50,000+ developers across 220+ organizations since then. We are based in the Boulder, Colorado area and are often enjoying the beautiful outdoors in Colorado with our families.

We believe software developers learn best through hands-on expert-led courses. Our instructors are industry-recognized experts in their domains and regularly contribute to open source projects. Every course we give is customized for each specific client, team, stack, and ability level. Tailored, customized, expert-led courses are the best way to give developers the knowledge and ability they need to do their jobs.

We’ve worked with a variety of clients and teams, large and small, including Yahoo, Intuit, Liberty Mutual, SalesForce, Starbucks,, Lenovo, Pearson, VMware, DISH, Ebay, Paypal, and many others.

We give back to our community and the developer community in many ways. We’ve sponsored the GoCode Colorado civic hacking competition every year since it started in 2014. Our instructors volunteer with local high schools programming classes and we’ve volunteered building houses, working in soup kitchens, and have done several other volunteer projects. We also sponsor multiple technical Meetups, including the Boulder Denver Software Club, the Boulder HTML5 users group, and the Boulder/Denver Java Users group.
