Lakewave does the research, the stitching and the first draft with AI, so you spend your time selling.
Lakewave tracks raises, new leaders, hiring and filings across your accounts and territory, and tells you the day something changes.
Find the decision makers, get mailbox-verified addresses and an AI draft written for that account, which you review. Send from your own inbox with open and reply tracking and a follow-up sequence.
Which accounts to pursue, why now, who to reach and what to say, matched to your product and the buyers you sell to.
Every address Lakewave gives you is checked against Tempest Therapeutics's mail server before you see it. Guessed addresses bounce, and bounces are what push a sender's domain toward the spam folder, so one bad list can cost a rep weeks of deliverability. Lakewave shows how each address was confirmed and leaves out the ones it cannot verify.
Use it two ways. Look up the verified address you need for a call you are already planning. Or let Lakewave do the whole job: find the accounts with a reason to buy now, the right people and their addresses, and draft a first email for each person, so you are not stitching together data sources and research by hand.
