Result: Doubled booked calls; $200K in upfront fees
“We pretty much doubled our booked call rate from three a week to about five to six a week. We've added $200K in revenue, and that's just in the upfront fees.”

Performance-based B2B cold email for $1M+ ARR companies. Look at the lead before the call. Skip it, no charge. Month-to-month.

“Just closed a 2.1k/m deal yesterday for copy only.”

“A lot of interested leads and ended up closing a client.”

“Closed my 2 biggest clients this week.”

“We closed 2 clients in the last week.”

“$50k deal closed.”

“We booked over 10 meetings from the first campaign.”

“Booked over 20 sales calls.”

“Literally did 4x booked calls and 3x calls taken.”

“Super knowledgeable on all things cold email. Highly recommend.”
I signed my biggest client last week for google ads. $6k/mo.
Hit my first 5-figure ($10,000) day.
“We pretty much doubled our booked call rate from three a week to about five to six a week. We've added $200K in revenue, and that's just in the upfront fees.”

“Three and a half weeks in, and he's already generated 28 qualified meetings, $130K in pipeline, and 3 closes - all from a vertical we weren't even touching before.”

“Within two weeks, we booked 8 meetings and closed 2. His speed of execution is absolutely unreal.”

“He worked with us very closely. A lot of great guidance. As a result of that, we closed 2 clients in the last week.”

“We must have been trying to get cold email working for three to four months with absolutely no success. We were able to book the same amount of meetings during that entire time just off the back of that first campaign.”

“We were able to generate leads predictably, and it gave us 8 new leads in under just one week. I highly and confidently couldn't recommend his service enough.”

“Thanks to his services, we were able to book an additional 20 booked calls in a month. He was fantastic from start to finish.”

“He helped me with my cold email and come up with a list of six million leads that allowed me to book over twenty sales calls. If you're looking for someone to help you out with cold email, James is definitely the guy.”

For B2B founders over $1M ARR — every single one we talk to is stuck in at least one of them.
You signed a three-month deal, sat through the kickoff, and watched a spray-and-pray campaign push tens of thousands of emails into the void. A trickle of curious replies. A handful of meetings that never closed. A renewal pitch you ignored. The money is gone. The pipeline isn't. "We've tried like five different outbound services over the last two years and none of them worked." — David Kettinger
Reputation built the business. For years, the people you'd worked with kept sending leads — until they retired, switched roles, or simply stopped. Networking has a ceiling, and you've hit it. "We were a referral business, 100% referral business. And that wasn't bad, but it was capped. We could never get bigger." — Paul Sherer
You asked your closers to "fit in" prospecting between deals. You hired one BDR and loaded them with qualification, events, and reporting. You stood up Apollo and capped at 50 sends a day per mailbox. Cold outreach is a volume game, and the people you have can't hit volume. So they don't. "The sales team has their own Apollo instance, but they're limited to like 50 emails a day." — David Kettinger
Fifty leads one month. Ten the next. Thirty after that. Google Ads hit diminishing returns. Meta dropped off the cliff. SEO traffic comes from outside your service area. You can't forecast revenue, you can't hire ahead of demand, and every payroll cycle quietly raises the question of how long this can keep going. "We get 50 leads one month, 10 another, 30 another, 60 another. It was just all over the map." — Sean Archer
Most agencies skip three of these stages. That's why your last vendor failed. Each step is built around a specific reason past programs broke.
Step 01
Your emails land in primary, not spam.
We set up 500-1000 email inboxes for you, so we can send 10,000-150,000 personalized emails to your prospects, on your behalf. This is one way you land in the inbox, instead of spam.
We put these inboxes on domains that are different from your main one, so your main domain stays untouched. Zero risk to your existing email reputation.
Step 02
Clean data, real decision-makers.
We use custom databases and our internal scrapers, not Apollo or ZoomInfo.
We qualify heavily on company job size, company revenue, the prospects job title, and any other relevant metrics that matter for you.
We find their emails, and validate them to be sure they're good to send to.
Step 03
Personalized, not templated.
We write many different messaging angles, to all different segments of your market. CEO's care about different things than HR Directors.
We personalize each email with something relevant - recent company news, hiring data, or anything else relevant.
Step 04
Reply handling & the pre-call reject gate.
This is the part most agencies bury — and it's the single biggest reason past programs felt rigged. When a prospect replies, a trained SDR handles the back-and-forth, answers objections, and books the call. Then, before the meeting happens, we send you the full email thread, the prospect's company data, role, and revenue signals. If it doesn't look right — wrong size, wrong title, wrong fit — you say no and it's cancelled. You aren't billed. The meeting doesn't count. You decide what counts, not us.
Step 05
We look at the messaging and angles that are performing the best. We cut the losers, and we double down on the winners. You continue to see even more qualified sales meetings.
This step alone is where most companies lose 30-50% of their potential meetings.
I built Jump Zebra because everyone is tired of paying marketing agencies $5k-10k per month, while getting locked into a 6 month contract.
That's why we work on a performance basis, and purely month to month.
Plus, the same way you found out about us, is the same way your prospects will find out about you. We take the same system that generated our meeting, and use it to generate meetings for you with your prospects.
You get to see the proof firsthand.
I'm a cold email snob. I couldn't find anything that was bad about it.
You hired a sales team, not another job. Here's exactly what lands on your plate vs. ours.
Here is exactly what happens week by week — what we build, what you approve, and how we throttle volume so the wins don't outrun your capacity.
Week 1
We set up domains and email inboxes for you, then learn about your services & your ideal customers.
Weeks 2-3
We build out qualified lead lists and messaging that will go out to those leads, that you get to approve before launch. Anything that you want changed, is changed.
Weeks 3-4
Campaigns go live on the 18th day. You'll start seeing meetings getting booked in the first week of going live.
Month 1+
We cut the angles that perform the worst, and double down on the angles that perform the best. Optimizing your campaigns even further. And we set the volume to what your team can actually handle — tell us five meetings a week, we run five; tell us to slow down, we slow down the same day.
