Know your target companies and know when they’re in market with Harpoons
Reach out at the right time
Enterprise sales is about timing. Harpoons shows you who to prioritize and why.
Ongoing monitoring
Our systems scan and assess each prospect in your list to find out when their business circumstances or needs change.
Prioritized for you
We develop a custom prioritization matrix for each client so our system can calculate which prospects you should reach out to right now.
See the future
Know what your prospects want at the earliest moment.
Know when strategy is changing
If they’re entering a new market or they’ve acquired a new company, you might need to know about it. We monitor big strategic movements and interpret how it could impact you.
Be ready when competition shifts
Does one of your prospects use your competitor? Swoop in after a price increase or unpopular update. React when your prospects are open to a switch.
When people change, deals do too
Keep informed of hiring data and trends. Have they hired new leadership? Or opened a new team? The arrival of new people is a strong opportunity to open a new deal.
Sell with the full context
You want to know:
- 01who they are
- 02what they’re doing
- 03when to contact
- 04why you’re contacting
- 05where to reach them
- 06how to open.
Harpoons AI does it all
Spray and pray sales strategies burn a short list. When you’re selling big-ticket to a limited market of a few thousand buyers, you can’t waste trust blasting poorly automated emails. You need to reach out with context. We built Harpoons AI to help you talk to the right people at the right time - for you, and for them.
Every account is custom
Every onboarding comes with a strategy meeting of up to 90 minutes to determine the factors and signals that matter to you.
We make sure that you surface opportunities, not just people.
