Funding alerts can help you waste less founder time, but they do not create demand by themselves. The useful signal is not "this company has money." The useful signal is "this company is likely changing in a way that makes our problem more urgent."
For first customers, that distinction matters. Founder-led prospecting works best when the message is grounded in a visible customer reality: a team is hiring, a function is forming, a process is breaking, a market is expanding, or a buyer now has a reason to care. A funding event can point you toward that reality, but it cannot replace research.
The mistake to avoid is building a giant recently funded company list and calling it traction work. A smaller list with clear ICP fit, trigger timing, buyer logic, and disqualification rules will usually teach you more than a large export full of companies you cannot credibly help.
