How DataStax replaced 11x.ai, ZoomInfo & Salesloft with Amplemarket to close 7+ enterprise deals in 5 months

DataStax is a leading AI agent development platform, helping enterprises scale generative AI app development with streamlined data integrations. The company thrives on innovation, but when it came to outbound sales, their existing 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 motion with Amplemarket’s Duo Copilot, gaining efficiency, control, and real pipeline growth along the way.

Back in 2024, Jackson’s team set an ambitious goal: land new enterprise logos at scale. But they were stuck with a fragmented, inefficient sales tool stack.

The team was stretched across 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 AI SDR tool, 11x.ai, had completely missed the mark.

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

The problem was a complete lack of visibility and control. 11x operated like 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 get on calls to adjust the value proposition, 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 into their outbound strategy and the ability to refine it along the way.

In Amplemarket, the DataStax team found a unified AI solution that still gave them the flexibility they needed to stay in control of their process.

Instead of juggling multiple tools for prospecting, sequencing, and engagement, reps could now manage everything from one place.

"With Amplemarket, all that busywork is gone. No more pulling leads from ZoomInfo, importing them into Salesforce, and then adding them to Salesloft. Now everything’s inside Amplemarket, or we pull leads from Salesforce and sequence them instantly."

The biggest game-changer for the DataStax team was Amplemarket’s Duo Copilot, a suite of AI agents that proactively find exclusive buying signals, research prospects in depth, and generate personalized multichannel sequences ready to send with no typing required.

With Duo's autopilot mode, outreach kept running in the background, even on days when Jackson wasn’t actively prospecting.

“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.”

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

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

"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."

Jackson further explains:

“That alone has been a game-changer and means we can explain how we differentiate ourselves against our competitors”

Unlike their experience with 11x's black-box AI, Amplemarket’s AI agents worked alongside their team by providing automation while keeping human decision-making in control.

“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.”

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

DataStax wasn’t looking for an AI tool to replace their sales reps or take away their strategic autonomy.

Instead, they chose to replace a rigid, black-box AI solution with a flexible, transparent AI Copilot that lets them maintain control over their messaging while optimizing their tech stack and ensuring every prospecting effort has real 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-recommended, signal-based prospecting, DataStax no longer wastes time on low-quality leads or struggles with scattered sales tools. Instead, they run leaner, smarter, and more effective outbound sales while keeping the human element.

If you’re wary of black-box AI tools that take away control but tired of juggling a bloated sales tech stack, Amplemarket can help.
