NYC based agent Jesse Miller has been representing Instagram photographers for some time, with Tinker Street Mobile. Collaborating with Instagramers with a large fan base has been one of the most effective ways for a brand to work on the platform, and Miller was quick to recognize the opportunity here. I'll be interested to see how things change now that there are more ways for brands to work with Instagram.
Either way, for agencies looking to engage some great Instagram photographers, their roster is a great place to start. And for creatives looking for inspiration, their commissions page shows off some beautifully executed work that really rings true for the platform.
