Posha began with a robotic arm that looked ready to take over the kitchen. Its useful invention came when the founders asked what people actually wanted at dinner: a machine that could stay on the counter and mind the pan.
The Cambridge startup spent a decade turning a four-zone, $1,200 contraption into a smaller two-zone system sold from $149 with a meal commitment. Its useful lesson is less about robots than about finding the one household job automation can actually own: making dinner wait for you.
