Upstream Ag designs and manufactures tools for the small vegetable farm in Burlington Vermont. We are connected to Pitchfork Farm, a 16-acre commercial vegetable farm located in an urban setting on the Intervale in Burlington, where we rigorously test all of our products (as well as grow veggies for the community!).

We also take on custom fabrication work and repairs. Contact us for more info at

Follow us on Instagram to have a peak at the latest prototypes coming out of the shop! 


Rob Rock has been growing vegetables commercially since 2002, and working in design & fabrication shops in the off-season since 2006 - including working for artists and sculptors, industrial crane builders, and high end industrial design firms.
