As answered by people managing Opalstack and Thayne.app.
Thayne.app's answer:
Most intake tools are forms. Thayne is a real conversation. It adapts to what someone says, follows up when an answer is vague, and produces a brief at the end rather than a spreadsheet of raw responses. The entire conversation is configured by the professional - their opening message, their questions, their voice, their definition of a good fit. It sounds like them at their best, not a generic chatbot.
Thayne.app's answer:
Thayne is the only intake tool built specifically for independent professionals who take inbound enquiries. It does not just collect information - it assesses fit, handles bad fits before they reach your calendar, and tells you exactly what to do with every prospect in a brief you can read in twenty seconds. Setup takes ten minutes and requires no technical knowledge.
Thayne.app's answer:
Independent coaches, consultants, recruiters, and estate agents - professionals who take inbound enquiries and whose time is directly tied to their income. Specifically people who are spending hours every week on discovery calls that go nowhere because qualification happens on the call instead of before it.
Thayne.app's answer:
Thayne was built after speaking to dozens of independent professionals who all described the same problem - they were giving away their best time and thinking to people who were never going to convert. The discovery call was the problem. Not the call itself, but the fact that by the time you know someone is not right for you, you have already spent the time. Thayne was built to move that qualification earlier, before anyone gets on a call.
Thayne.app's answer:
