How Cozero booked 46 meetings and built $1.2M in pipeline in under 2 months with Amplemarket

Before diving in, hear it directly from Sylvie.

In this short video, she walks through how she evaluated and consolidated Cozero's entire sales stack, why Amplemarket stood apart from a shortlist of six tools, and the results her team achieved in under two months.

The sections below go deeper on each of those moments.

Why Cozero chose Amplemarket

Cozero was founded in 2020 with a clear mission: help the corporate sector shift toward a lower-emission economy. Their Climate Action Platform consolidates greenhouse gas emission data across scopes 1, 2, and 3, enabling enterprises to measure, monitor, and act on their carbon footprint.

Sylvie Cubbage joined Cozero just three months before this conversation. Her background spans business development, sales, enablement, and revenue operations, and at Cozero she covers all of it, supporting a lean team of one head of sales and two account executives, while running the go-to-market engine in the background.

Why did a fragmented tech stack hold Cozero back?

When Sylvie joined Cozero, her first move was an honest audit of the existing tech stack: what they had, how it was being used, where the gaps were, and where the budget could be cut.

What she found was a story she had lived before across her entire career in sales.

"Fragmented systems: this doesn't just apply to Cozero, but my whole career. I've always had at least five to six sales tech tools just to get the job done."

1. A stack built on compromises

Cozero was running HubSpot sequencing as their primary outbound tool, LinkedIn Sales Navigator at the corporate level (~$12,000 for 10 seats), Lusha for data enrichment, Apollo, and Surf.

Each tool addressed one piece of the puzzle without connecting to the rest.

Social activity was tracked manually or simply fell through the cracks, and data from enrichment tools entered HubSpot inconsistently, making reporting unreliable.

2. The cost of running five tools for a small team

For a team of Cozero's size, a multi-tool stack carries a cost far beyond the invoice.

Sylvie describes the training burden, the constant context-switching between platforms, and the hours lost to tasks that should have been automated. She shared how by the time you add enrichment, sequencing, social automation, and outreach on top of HubSpot, the total cost for five people runs over €24,000/year.

Not accounting for the time each rep lost bouncing between platforms every single day.

3. No personalization at scale

Cozero operates in the complex, highly specific vertical of enterprise carbon management, so generic outreach does not work here.

Sylvie needed a way to reach the right people with tailored messaging across multiple channels, at a volume a lean team could sustain. With the existing stack, that combination was simply out of reach.

She qualified it as "impossible. You actually couldn't do it unless you were doing extremely targeted account-based marketing for just one account with 10 to 20 personas. And even that took so much time for just one account."

Why Cozero chose Amplemarket over Honeysales, Outreach, and others

Sylvie ran a structured evaluation before committing to any tool. The shortlist included traditional sequencing platforms like Outreach and Salesloft, social automation tools like HeyReach, and more advanced all-in-one platforms, including Clay, Honeysales, and Amplemarket.

In the video, Sylvie walks through this evaluation, including the exact tools she compared and the moment Amplemarket stood apart. The decision ultimately came down to Amplemarket and Honeysales.

Where Honeysales fell short

Honeysales offered solid intent signals and account targeting, but imposed a strict monthly limit on the accounts and contacts a team could reach. For a small team that needed both quality and volume, that was a dealbreaker.

What pushed Amplemarket to the top

Amplemarket delivered what no other tool on the list could: personalization at scale, combining intent signals, AI-generated sequences, and multichannel outreach in a single platform.

"It came down to this idea of personalization at scale. Being able to integrate all of the signaling, all of the intent, utilizing AI, and pushing it at volume. We can't compromise on scale, but we also don't want to do the traditional spray and pray."

The free trial sealed it, as within two hours, Sylvie had onboarded herself, launched her first sequence, and booked her first meeting within days.

A month later, she had four meetings from her own outreach alone. Two weeks after signing the contract, she had rolled it out to the wider team. Highlighting how "it was a very quick time to value, straight away."

How Amplemarket replaced five tools and transformed daily workflow

After a structured evaluation, Cozero chose Amplemarket's all-in-one AI sales platform to replace their fragmented stack.

The decision was driven by one thing no other tool could offer: the full end-to-end sales workflow, from data and signals to multichannel sequencing and reporting, in a single place.

1. From five tools to one: consolidation that actually sticks

The most immediate change after switching was consolidation. Sylvie's previous stack included HubSpot sequencing, LinkedIn Sales Navigator, Lusha, Apollo, and Surfe.

Today she works out of two tools: Amplemarket and HubSpot as her CRM.

In the video, Sylvie puts it plainly: think of every tool a salesperson needs end-to-end, put them all into one, and have it do each job better than the individual tools did.

The cost impact was equally concrete, as the previous stack was running at over €24,000/year and Amplemarket came in at around €12,700 per seat, cutting total tooling cost by more than half.

But beyond the invoice, the hidden cost that disappeared was the time: no more training reps on five different platforms, no more data falling through the cracks between tools, no more manual cross-referencing just to track a single prospect's activity.

Data quality also improved across the board. Sylvie was direct in her assessment:

“Data quality is better than Lusha, ZoomInfo, and any other enrichment sequencing. It's way more powerful than any other sequencing tool out there. It's crazy, really.”

{{testimonial-person}}

Amplemarket's native B2B database outperformed every enrichment tool she had used throughout her career. Bounce rate dropped from 7.51% to 0.6%, and email open rate jumped from 29.41% to 66%, both measured against Cozero's previous performance in HubSpot sequencing.

2. Social selling, finally integrated

Social channels are where Cozero's enterprise buyers are active, and before Amplemarket, social outreach was either handled manually or through standalone tools like HeyReach.

The core problem with those tools: they did not connect to anything else. Social activity went unlogged, required manual cross-referencing with the rest of the stack, and routinely fell through the cracks.

"I would always have to cross-reference and bounce back and forth. And usually, LinkedIn was the first to get lost. How do you even keep track of that activity? You actually couldn't. You had to do it completely manually", Sylvie shared.

Amplemarket made social a native channel within sequences, alongside email and phone, with streamlined connection requests, messages, profile visits, AI voice notes, and conditional logic all built in.

The conditional logic was a specific highlight for Sylvie: being able to set rules directly inside a sequence meant she no longer had to manually decide what to do when a prospect did not respond on one channel, as the sequence handled it automatically.

3. Duo Copilot: signals and personalization at scale

Sylvie starts every working day with slight variations of the same flow: signals, tasks, Unibox.

Duo surfaces buying intent signals from over 100 sources and, critically, generates a tailored multichannel sequence automatically based on each signal.

This is what separates it from every standalone intent tool Sylvie had encountered before: the signal and the sequence are connected, not two separate steps across two separate tools.

"Being able to take it to the next step and already have the sequence there, this is insane. That saves me at least an hour per person. And you can do 15 of those a day per rep. That's already 15 hours saved, just on the signals alone."

{{testimonial-person}}

Her process adds another layer of precision on top.

Before building a sequence, Sylvie creates a messaging matrix: segmented by industry, by persona, by challenge and value proposition.

She feeds that structure into Amplemarket's AI-assisted sequence builder, cross-references the output with Claude, and uses the result as a scalable template baseline. What would have taken days of individual copy work per account now runs as a repeatable daily system.

“I'm still using Claude to build sequences, and being able to push that directly and analyze performance from Amplemarket directly in Claude, it's incredible. So many use cases.”

4. Reporting that outperforms HubSpot

One benefit Sylvie did not anticipate: Amplemarket's analytics dashboard is cleaner and more reliable than what Cozero currently has in HubSpot.

For a team rebuilding their outbound baseline from scratch, this matters more than it might seem.

Before Amplemarket, fragmented reporting across tools made it genuinely hard to know how many meetings were being booked, what qualified as an opportunity, or whether pipeline numbers reflected reality. Fields in HubSpot were not aligned, quota did not exist, and unqualified deals were inflating the numbers.

"The dashboard I have here with the breakdowns is much cleaner than what we even have in HubSpot right now.”

{{testimonial-person}}

With Amplemarket's unified analytics, Sylvie now checks performance daily: her own numbers and the wider team's, all in one place. It gave Cozero the clean baseline they had never had before, and the visibility to actually improve on it.

What does Amplemarket ROI look like for a small sales team?

In under two months of using Amplemarket across a team of three reps, Cozero went from a fragmented, baseline-less outbound operation to one of the clearest ROI stories in the stack.

{{results-cards}}

These numbers carry extra weight given the context that Cozero had no reliable outbound baseline before Amplemarket.

"In just the last two months, we have 46 meetings booked, which is really amazing, and a huge step up from where we were."

{{testimonial-person}}

The email deliverability improvement tells its own story:

• Bounce rate dropped from 7.51% to 0.6%
• Open rate jumped from 29.41% to 66%

Both measured against Cozero's previous performance in HubSpot sequencing.

These aren't vanity metrics: they protect domain reputation, improve inbox placement, and compound over time.

Paired with an open rate that jumped from 29.41% to 66%, Cozero's outbound emails are now reaching and resonating with the right people at a rate that most sales teams never achieve.

The $1.2M in pipeline from 46 meetings, at a 50% meeting-to-opportunity conversion rate, gives Cozero a clear and repeatable foundation to build on. With a target conversion rate of 60-70% ahead, the trajectory points firmly upward.

When Sylvie Cubbage joined Cozero, the outbound engine was effectively starting from scratch.

The tech stack was fragmented across five-plus tools, social activity was untracked, and there was no reliable baseline from which to measure progress. The budget was being consumed by tools that each solved one piece of the puzzle without connecting to the rest.

Within two months of switching to Amplemarket, the picture looks entirely different:

• Email open rates more than doubled
• Bounce rates dropped by over 90%
• 46 meetings were booked, generating over $1.2M in pipeline.

The entire outbound operation now runs from a single platform, at less than half the cost of the old stack.

"Think of every tool end-to-end: prospecting, sourcing, enrichment, outreach, intent, signals, automation. Think of all of that, which is always a baseline of five to six tools. Amplemarket can do everything in one. And it's AI-driven. That's how powerful it is."
