Choozle, a programmatic ad platform headquartered in Denver, on Wednesday announced it has raised $4.1 million in a Series A round of funding.

Great Oaks Venture Capital led the round and was joined by others, per Andrew Fischer, Choozle’s co-founder and CEO. “Mostly seasoned individual investors and some family office money,” he added.

The Series A round comes nearly one year after Choozle pulled in $1.8 million in a Series Seed round, which was also led by Great Oaks Venture Capital.

Choozle claims it saw 71% month-over-month growth over the final four months of 2014, and says it now has over 100 clients including Cricket Wireless, Gaiam, SendGrid, Willow Tree and others.

Choozle’s impressive end to 2014 went hand-in-hand with the rise of in-house trading desks -- and it’s no coincidence.

Fischer said in a statement the company’s goals it to bring “programmatic to the people,” and many “people” -- in this case, agencies -- were looking to bring programmatic in-house in 2014. For example, YouConnex, a Choozle client, has built an in-house trading desk using Choozle’s platform.
