B2B outbound starts with finding the right accounts. That hunt eats the week, then comes a first email and luck. WindowIsOpen is OSINT AI that cuts the research. It reads public company changes against what you sell. One question: is there a window here now? A company hiring engineers may be busy. That doesn't mean it's your window. Pick what you sell, run Suggested, or paste domains you know. Not a lead list. Not a mail writer. Free during launch.
