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
Cold infrastructure — domains and inboxes.
Founders who tried this in-house tell us the same thing: "We don't want to use our own website email." They're right. Sending 50 cold emails a day from a real domain tanks it inside a week. We register 10–100 separate sending domains, redirect them to your main site, and provision 500–5,000 individual inboxes across them.
Each inbox warms for 17 days, sends a maximum of 5 emails per day, and rotates out automatically as it fatigues. Open-rate tracking is disabled — it's been a deliverability killer for five years and your previous vendor was almost certainly still using it. Your real domain stays clean.
Step 02
Prospect sourcing — not Apollo.
"One company was using Apollo. We weren't getting any results from that database." — Dan Demaree. Apollo gets hammered — every agency pulls the same list.
We scrape Google Maps, custom directories, and four other databases most agencies don't touch, then layer hard filters: revenue band, headcount, job title, technographic spend, geography.
Every email gets verified through three independent providers before send. You approve the final list before a single message goes out.
Step 03
Segmented messaging + AI personalization.
We split each campaign by segment (CEO vs. operator vs. controller — they care about different things), then use Clay-based AI to pull each prospect's company description, their ICP, and their named competitor into every email.
Three to five angles run in parallel per segment, all A/B tested. "I'm a cold email snob. I couldn't find anything that was bad about it." — Alex Hively.
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
Each week we pull reply-rate, positive-reply-rate, booking-rate, and show-rate for every angle, segment, and inbox cohort. Angles below the threshold get cut. Winners get cloned into adjacent segments. Inboxes that fatigue get rotated; domains nearing reputation drift get replaced before they ever spam. You get a 10-minute weekly report showing exactly which angles are winning — not a black box.
The same loop that took one client from 3 booked calls a week to 5–6, adding $200K in upfront fees.
I built Jump Zebra because I kept hearing the same story from B2B founders doing $1M+ a year: you paid an agency $5K–$10K a month, signed a six-month contract, and got nothing back you could put on a P&L. Maybe a handful of "interested replies" over six months. Maybe a calendar of tire-kickers who never showed. One founder told me on a discovery call: "five different outbound services over the last two years and none of them worked."
The category is broken on purpose. ListKit, Sales Hive, Abstract Marketing, Vendry, Embrace Benchmark — different logos, same playbook: lock you in, send 1,500 generic emails a month, blame deliverability, keep the retainer. Another founder I spoke with paid four months to ListKit and put it bluntly: "They didn't bring me anything. You didn't hold up your promises."
So we don't do retainers without performance. Month-to-month, you only pay for qualified meetings that actually show. And here's the structural proof — the same cold-email system we use to book your prospects is the one that got you on a call with us. You're seeing it work on yourself right now.
When you book, you talk to me directly. Not an SDR. Not a "growth advisor." Me.
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
Day one: 30-minute onboarding form, one onboarding call. We set up 10–100 alternate domains and 500–5,000 mailboxes — none on your main domain. Warm-up begins immediately.
Weeks 2-3
While inboxes warm, we build your qualified lead list from our own scrapers and custom databases — not Apollo, not ZoomInfo. You see every lead and every email variation before a single send. Anything you want changed gets changed.
Weeks 3-4
On day 18 the campaigns send. Reply handling is live the same morning. First booked meetings typically land in the first week post-launch. You can reject any meeting as unqualified before the call — it never counts as billable.
Month 1+
We cut underperforming angles and double down on winners. We set volume to the number you can fulfill — not the maximum we can produce. Tell us five meetings per week, we run five. Need to slow down? We slow down the same day.
