How ColdSpark works

Four steps. Zero babysitting.

01

Research

ColdSpark crawls LinkedIn, company websites, news, and funding data to build deep prospect profiles. It knows what your target cares about before the first email is sent.

02

Personalize

Every message is crafted for a specific person. Not mail-merge tokens. Real references to their work, their company's challenges, their recent activity. Messages that feel written by a human who did their homework.

03

Engage

Multi-touch sequences across email and LinkedIn. Smart follow-ups that adapt based on opens, clicks, and replies. ColdSpark knows when to push and when to pause.

04

Book

Qualified prospects get routed straight to your calendar. ColdSpark handles the back-and-forth on scheduling, timezone coordination, and meeting prep. You just show up.

What outbound teams are saying

"We generated 47 replies in the first week. I'd given up on cold email as a channel — it was embarrassing sending generic templates. ColdSpark changed that. My open rate went from 8% to 34%."
MC
Marcus Chen
Co-founder & CEO, Apex Growth
"Reply rate jumped from 1.1% to 8.4% in month one. I'm not an SDR — I'm a founder who was doing this manually and badly. The follow-up sequences alone have booked 12 calls I would have missed."
SO
Sarah Okafor
Founder, Stackwave
"Setup took 20 minutes. My first campaign was done by lunch. By Friday I had 8 qualified replies for a product that didn't exist a month ago. If you're still writing cold emails manually, you're working 10x harder than you need to."

The last SDR you'll ever need to hire

Sales teams are drowning in tools that require more work to manage than they save. ColdSpark is the opposite. It's an employee, not a platform. Point it at your market, and it goes to work. Every morning your inbox has new qualified meetings from prospects who actually want to talk to you.
