We present the results of calculations of the in situ accretion of planets on sub-Au scales, for a range of disk masses. We show that massive planetesimal disks can reproduce the properties of observed Hot Neptune systems, suggesting that migration is not required to produce large core, gaseous envelope planets on small scales. For lower mass planetesimal disks, rocky planets are more common, and are compared to the emerging Kepler results.
