Profile introduction
Source excerptLinkedIn [2]

At this+that we're building AI that reads your inbox and does the work hiding there. It drafts replies, routes content to the right place (invoices → finance), creates digests to save you from reading things as they arrive and runs workflows you describe in plain English. It's like an enterprise/team version of OpenClaw. We just relaunched in beta and we're onboarding design partners. If you spend too much time each day in email/Slack/Teams, feel like your inbox runs (ruins?) your life and want to influence what gets built next, I'd love to talk. You get white-glove onboarding, a direct line…
