Key takeaways from 2 million+ calls to owners

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.

Don't want to make the calls yourself? Rejigg does the outreach for you — we've made 2 million+ calls to business owners so you don't have to. Want a dedicated team running your search? Rejigg Concierge pairs you with a deal team that sources, screens, and introduces you to owners who are ready to sell.

FAQ

The US has roughly 6 million employer firms (businesses with at least one employee). We use 2 million as the baseline for "acquirable small businesses" — filtering out sole proprietorships, very large firms, and businesses that are too small to be realistic acquisition targets.
The default rates come from Rejigg's actual data across 2 million+ calls to business owners. Your results will vary based on industry, geography, and outreach quality — use the sliders to model different scenarios.
It's the statistical likelihood that at least one business in your buy box results in a closed deal, given the conversion rates at each funnel stage. We calculate this using binomial probability — the same math used in any pass/fail scenario with many independent attempts.
Rejigg reaches out to hundreds of thousands of business owners every year. We identify owners who are open to a conversation and connect them with qualified buyers on our platform. Instead of cold-calling thousands of businesses yourself, you can focus on meeting owners who are already interested.
