Scaling isn’t just about headcount – it’s about keeping performance high while expanding your people, process and platform.

Welcome to the final chapter in our series breaking down Firmable’s recent webinar with David Feinberg (The Growth Factory), focused on building a high-performance SDR engine. In Part 1, we covered how to create a predictable pipeline with SDRs and a clear Ideal Customer Profile (ICP). Part 2 unpacked how to hire and align your SDR team for early momentum.

Now in Part 3, we focus on scale. From 1 rep to 50+ SDRs, David’s experience at Eftsure highlights what it really takes to scale outbound prospecting without losing effectiveness. We’ll also shift gears – instead of repeating why SDR-marketing alignment matters, we’re digging into how to operationalise it at scale through data, tooling, and GTM rituals that keep your pipeline firing.

Scale your SDR team with intention, not just headcount

When your SDRs start consistently booking more meetings than AEs can handle, the instinct is to hire fast. But without the right infrastructure, more reps can mean more chaos – not more pipeline. As David puts it, “Don’t just throw headcount at the wall.”

Instead, scale in phases. Cement a repeatable playbook with your first 2–3 reps – cadences, call scripts, tools, onboarding steps – and expand gradually. Add a team lead once you pass five reps. Introduce structure around coaching and peer learning. At Eftsure, the team didn’t leap from five to 20 reps overnight – they scaled deliberately, ensuring every cohort matched the original bar for quality and training.

Your first few SDRs will define the culture –  so make sure it’s one you want to scale.

Culture and recognition: The fuel behind SDR resilience

Scaling means more volume, more noise, and more rejection. That’s why culture matters more as you grow. Recognition is critical. Celebrate every milestone – first meetings, objection comebacks, deals sourced. Make motivation visible: Slack shout-outs, bells, dashboards, sales floor energy.

Think of it as professional sport – SDRs are in a high-performance environment, and like any athlete, they need coaching, and team wins to stay sharp. David shared how Eftsure introduced micro-progression paths: small promotions, ownership of internal projects, public praise. These built pride and retention without relying solely on title jumps.

And resilience? That’s coached too. Regular stand-ups shared “worst rejection of the week,” and honest conversations about burnout created a feedback loop that kept the team healthy and hungry.

1 + 1 = 3: When SDR and marketing work in sync

Alignment isn’t just a checkbox – when SDRs and Marketing collaborate well, their impact compounds.

For campaigns that we run at Firmable we pair a marketing email drip with targeted SDR follow-up to clickers. The result? Double-digit conversion lifts. Why? Because the SDR calls land in warm territory – the prospect already knows who we were.

David used a boxing metaphor to explain it: marketing is the jab – it gets attention, softens the target. SDR is the cross – it lands the opportunity. You need both.

But that level of orchestration doesn’t happen by accident. It happens when you intentionally connect your GTM engine.

Let’s break down how to do that at scale.

Data and signals integration: Make outreach land on warm ground

As your SDR team grows, so does the volume of outreach. To avoid burning lists and missing timing, you need better signals – and better syncing.

At Firmable, we use AI-powered signals to detect high-signal events (like job changes, funding, or team growth) and surface them directly to our SDRs. Combine that with marketing engagement data (e.g. ad clicks, webinar attendance, or guide downloads), and you’ve got a roadmap for relevance.

For example:

• A CFO downloads your guide → SDR follows up with a personalised angle
• A target account hires in IT → SDR references team growth and tech needs
• A prospect visits your pricing page → SDR calls within the same week

Signals transform cold calls into timely, informed conversations. And at scale, they prevent wasted effort – letting SDRs prioritise the right accounts at the right moment.

Process maturity curve: Scale GTM like a system, not a scramble

What works with 3 SDRs won’t hold at 30.

Once you hit team scale, you need maturity in your go-to-market (GTM) process:

• Playbooks: Centralised documentation that evolves with feedback
• Dashboards: Shared reporting between Sales, Marketing and SDRs
• Feedback loops: Regular insights from SDR calls passed to Marketing

As David puts it: “The best teams aren’t guessing – they’re capturing what works and making it repeatable.”

At Eftsure, GTM maturity meant SDRs could operate autonomously while still staying aligned. New reps weren’t starting from scratch – they were onboarded into a refined machine.

Enablement and tooling: Give reps the system to succeed

Scale breaks process – unless your sales enablement tools are built to flex.

For SDRs, the essential stack includes:

• A single CRM that Marketing, Sales and SDRs can all live in (e.g. HubSpot or Salesforce)
• A sales intelligence tool (like Firmable) for enriched contact data and buying signals
• Sequencing and automation tools to manage outbound at scale

But David’s advice was clear: less is more if the sales enablement tools are connected. Too many disconnected systems lead to lost context and dropped handovers. The best tooling setup supports consistent workflows and shared visibility – not complexity.

Pro tip: SDRs should have visibility into campaign performance and prospect interactions. Marketing should know which outbound pitches are landing. That’s how tools become enablers – not blockers.

Weekly rituals: The 3 meetings that keep teams aligned

Rituals create rhythm – and alignment thrives on rhythm. Once you’re scaling, set recurring syncs between SDRs, Marketing, and Sales.

Here are three that work:

1. Campaign pre-briefs :Before launching any outbound push, bring the teams together. What’s the ICP? Messaging? Offer? Timing?
2. Weekly SDR stand-ups: Cover performance metrics, share call wins/losses, and adjust cadences.
3. Feedback share backs: Marketing joins to hear what’s resonating. SDRs share objection trends and message friction.

These rituals ensure your GTM engine stays coordinated – and your messaging stays sharp.

Conclusion: Scale with intent, win with alignment

Scaling your SDR team isn’t just about increasing activity — it’s about building a repeatable, high-performance sales development motion. The most successful outbound engines combine intentional hiring, a culture of recognition, and well-documented processes that scale.

But to truly unlock predictable pipeline, your SDRs can’t operate in isolation. They need to work in sync with Marketing and Sales through shared tools, shared data, and shared rituals. That’s how you move from one-off wins to a cohesive, scalable go-to-market strategy.

Whether you’re expanding from 3 SDRs to 30 or levelling up an established team, focus on what matters: great people, GTM alignment, and timely outreach powered by buyer intent signals. That’s how you turn effort into efficiency — and outbound into outcomes.
