Rejigg has made over 2 million phone calls to business owners on behalf of searchers. Here's what we've learned about what it takes to close a proprietary deal.
Aim for at least 6,500 businesses in your buy box
Roughly 1 in 4,000 contacts results in a closed deal at benchmark conversion rates. At those odds, you need thousands of companies in your universe to have a realistic shot. A buy box with 6,500+ businesses gives you about an 80% chance of closing — below 1,000, you're down around 20% and relying on luck.
Be flexible on at least one dimension
The most successful searchers we've seen are industry-focused and geography-flexible, or geography-focused and industry-flexible. Being restrictive on both industry and geography is the most common reason searches stall.
If the calculator shows a low probability, try adding adjacent industries (e.g., expanding from just HVAC to all home services can 3-4x your universe) or widening your radius.
Plan for 18-24 months, start to finish
At 50 new contacts per week, the ~4,000 contacts a typical close requires is about 18 months of outreach. But you don't need to exhaust the list — you need one deal. The math favors starting with a large enough pool that you find it in the first pass.
Once you connect with an interested owner, expect 6+ months from first meeting through diligence and close — some of which overlaps with your ongoing outreach.
Half the battle is finding contact info
You'll only find good contact information for about 50% of businesses in your buy box. That's the first and biggest haircut to your universe — before you've even picked up the phone. Tools like ZoomInfo, Apollo, and LinkedIn Sales Navigator help, but none cover every small business.
