Every business on this list has the same leak: it pays to generate visits and calls, and most of that demand leaves without a name. The usual fix is a tool per channel, each with its own tag, contract, and copy of your customers, so the same person gets paid for again and again. Bituser resolves each person once, into a graph you own, and reuses that resolution everywhere. The return compounds: every channel you add starts with people you already know.
