When a business owner says they're interested, Sandbox's reps know within seconds, and the lead lands in their Slack and CRM.
Five short examples. AI prospecting: asked to find local businesses, the AI finds three, then each one's decision maker, then verifies their emails. AI copy: the AI writes a whole short personal email, subject and all, then it is ready to send. AI replies: one lead asks about price, the AI asks how big their sales team is and books a call; another lead has no team or budget yet, so the AI closes it out politely as not a fit. Follow-ups go out on days 1, 4 and 9 until the lead replies. Booked calls fill the week.
Every send, reply and booked call lands in one live dashboard. Our AI watches it around the clock, so problems get fixed before you'd ever notice them.
If thousands of companies could buy what you sell, we can fill your calendar.
If you sell a B2B service and thousands of companies could buy it, yes. If your whole market is a few dozen named accounts, cold email at our scale isn't the right tool, and we'll tell you that on the call.
We're your AI-forward outbound team. We build the lead list, write the emails, send them, answer the replies with AI, and book the sales calls onto your calendar.
Each client gets its own brain: your offer, your pricing, your proof and your tone. Replies draw from it and are written to read like you typed them yourself.
Yes. Replies can wait for your approval, or send on their own once you trust them. You choose, and you can change your mind any time.
Named decision-makers who match the buyer you describe. Every email address is checked before anything is sent to it.
Yes, many of our clients are agencies. Each of your clients gets a separate workspace with its own lists, copy and inboxes.
Book a short intro call. We'll look at your offer and your market and tell you straight whether it's a fit.
