Background

DataStax is a leading AI agent development platform that helps enterprises scale their generative AI app building with streamlined data integrations. The company thrives on innovation, but when it came to outbound sales, they hit a major roadblock: their existing sales engagement tools weren’t delivering results.

Jackson Reimers, Director of New Enterprise Business for America & Canada, was on a mission to change that. This is the story of how DataStax transformed its outbound sales motion with Amplemarket’s AI copilot — gaining efficiency, control, and real pipeline growth along the way.

‍

The challenge

Back in 2024, Jackson’s team set an ambitious goal to land new enterprise logos at scale. Unfortunately, they were relying on a fragmented and inefficient sales tool stack. The team was stretched between multiple platforms — including ZoomInfo, SalesLoft, and Lusha — to find and engage prospects. The process was clunky, requiring reps to jump between tools, import data manually, and constantly tweak messaging.

To make matters worse, their previous AI sales tool, 11x, had completely missed the mark.

“We didn’t see the level of qualified opportunities we had expected from 11x based on their projections."

‍

The problem? A complete lack of visibility and control. 11x operated as a black box — once their AI agents took over outreach, DataStax had no way to steer or refine 
the messaging. Each week, they had to hop on calls to tweak the value prop, with little tangible improvement
— as Jackson explains:

“I don’t want to get on a call each week and tinker with messaging over and over. That’s not progress.”

DataStax needed a solution that combined AI efficiency with human oversight — something that could automate the grunt work while still giving the team full transparency over their outbound strategy and the ability to refine it along the way.

‍

The solution

In Amplemarket, the DataStax team found the ideal unified AI solution that still gave them the flexibility they needed over their processes.

Instead of juggling multiple prospecting, sequencing, and engagement tools, reps could now manage everything from one place with automation that worked for them, not instead of them. Jackson tells us:

"With Amplemarket, all that busywork is gone. No more pulling leads from ZoomInfo, importing them into Salesforce, and then adding them to SalesLoft. Now, we’re either prospecting inside Amplemarket and dropping leads straight into sequences, or pulling leads from Salesforce and sequencing them in seconds.”

‍

The biggest game-changer for the DataStax team was Amplemarket’s AI-powered Duo Copilot and its always-on autopilot mode, which kept outreach running in the background — even on days when Jackson didn’t actively prospect.

“There are days where I never go into Amplemarket, but I’ll log into LinkedIn and just respond to people who replied to
my autopilot outreach. That’s the dream.”

‍

The results

With Amplemarket, DataStax transformed their outbound performance in less than 5 months:

• 65+ enterprise opportunities generated
• 7+ deals booked and counting
• 19% average reply rate on Duo LinkedIn signals
• 9.5% interested rate on Duo LinkedIn signals
• 3x replies on Duo leads (compared to average across all leads)

‍

Jackson particularly valued Duo’s intelligent prospecting signals, which helped the team target high-intent accounts instead of wasting time on generic lists.

“I love the ability to filter by LinkedIn keywords. Instead of just building a list and guessing, I can now say, ‘Find me every company using Cassandra’ and Duo brings me people who are talking about Cassandra or I find them in the Searcher. That alone has been a game-changer and means we can explain how we differentiate ourselves against our competitors.”

‍

And unlike their experience with 11x’s black-box AI, Amplemarket’s AI copilot worked alongside their team — providing automation without removing human decision-making.

“I like that I can still use my judgment. The AI generates outreach, but I decide what goes out. That level of control is huge.”

‍

On top of these tactical gains, moving to Amplemarket’s all-in-one solution allowed DataStax to eliminate redundancies and cut their total spend on sales engagement tools—without losing functionality.

"Amplemarket isn’t more expensive if you can drop multiple tools. For us, it definitely saved us money. When you add that up across an international sales team, your savings are pretty significant."

‍

Conclusion

For DataStax, the combination of cost savings, automation, and control made Amplemarket a no-brainer—helping them land new enterprise accounts without overspending or overcomplicating their stack.

DataStax wasn’t looking for an AI agent that would replace their sales reps or rob them of their strategic autonomy. 

By replacing a rigid, black-box AI solution with a flexible, transparent AI Copilot, DataStax realized they could maintain control over their messaging while optimizing their tech stack and ensuring every prospecting effort had impact.

"We believe in AI, but we also believe in control. With Amplemarket, we get both — AI that accelerates our work, not one that forces us into a black-box approach."

By embracing AI-driven, signal-based prospecting, DataStax is no longer wasting time on low-quality leads or struggling with scattered sales tools. Instead, they’re running leaner, smarter, and more effective outbound sales, without losing the human element.
