As you say big companies are building these so there's clearly a market need not being met. Cursor, Claude, and other have started getting into it with background agents but they still drive like the local agent just wrapped into the cloud, they still need prodding to get work done. I've been building Gibon (https://gibon.ai) for exactly this to try and hit this market need. We're running a pilot program right now, check out the site and fill out the form if you're interested and we'll be in touch.
