Month Engagements

Real Results, Real Companies, Real Revenue

These case studies represent actual engagements with real companies, generating real pipeline and real revenue. Company names and specific identifying details are anonymized to protect client confidentiality, but every metric—pipeline value, timeframe, conversion rate, cost per meeting—is based on proven, measurable results.

The pattern is consistent across all engagements: identify the biggest GTM infrastructure blocker (broken CRM, no enrichment, manual chaos, poor targeting), build the system, train the team, and hand it off. Pipeline and productivity compound from there.

These aren't hypothetical case studies or best practices from a textbook. They're what happens when a GTM engineer gets hands-on access to your sales stack, your team, and your GTM motion for 90 days.

Rebuilding a Broken CRM and Outbound Stack

Company Type

Series A SaaS (Post-Acquisition)

Stage

Post-M&A integration

Setup

30 employees, $2M ARR, had invested $200K in sales stack that was broken and unusable

The Challenge

  • CRM (Salesforce) was a mess: 2000+ duplicate records, bad data, unusable
  • Had spent $200K on HubSpot, Salesloft, Apollo, and other tools that weren't integrated
  • Email deliverability was only 65% (domains blacklisted, poor infrastructure)
  • SDRs spending 80% of time on manual data entry and CRM cleanup instead of selling
  • Sales team had lost trust in tools after previous failed implementation
  • Leadership questioning ROI on sales stack (wanted to pull the plug)

The Solution

  • CRM audit and rebuild: cleaned up Salesforce, deduped records, rebuilt account hierarchies and deal stages
  • Deliverability remediation: domain reputation repair, authentication setup (SPF/DKIM/DMARC), email provider migration
  • Rationalized tech stack: eliminated duplicate tools, integrated remaining tools (Apollo → Salesforce → email → reporting)
  • Built automation layer: eliminated 80% of manual data entry through Salesforce workflows and integrations
  • Implemented data governance: processes to prevent future data decay
  • Trained sales team on new system and workflows
  • Established SDR productivity metrics and success dashboards

Timeline & Execution

Month 1: Audit and Foundation

  • Comprehensive CRM audit (data quality, record structure, automation)
  • Salesforce deduplication campaign (2000+ duplicate records merged)
  • Email deliverability audit (domain reputation, authentication setup)
  • Tech stack rationalization (identified redundant/unused tools)
  • Sales process mapping (account stage, deal stage, qualification)

Month 2: Build and Implement

  • CRM rebuild: account hierarchies, deal stages, custom fields for pipeline management
  • Salesforce workflow automation (auto-task creation, lead scoring, routing)
  • Email deliverability fix: domain setup, authentication, email provider migration
  • API integrations: Apollo → Salesforce, Salesloft → Salesforce
  • SDR training on new system and data entry standards

Month 3: Handoff and Scale

  • Deliver CRM documentation and playbooks
  • Productivity dashboards live (meetings, response rates, deal velocity)
  • Weekly cadence calls to monitor metrics and iterate
  • Scale prospecting campaigns across cleaned data
  • Sales leadership reporting on new metrics (previously impossible)

Tools & Platform Stack

Salesforce CRM (core system)Apollo (enrichment - integrated)Salesloft (sequencing - integrated)Google Workspace (email with proper auth)Zapier (workflow integrations)Custom Salesforce dashboards (reporting)

Key Insight

A broken CRM is worse than no CRM. It destroys team morale and makes data-driven decisions impossible. Rebuilding was expensive ($12K investment) but freed up 25+ hours per week of SDR time and doubled meetings per month. The team went from avoiding the CRM to trusting it because the data was finally clean and useful.

Common Patterns Across All Engagements

Infrastructure Always Comes First

No amount of cold outreach will scale if your CRM is broken, your data is messy, and your tools aren't integrated. Every engagement starts with infrastructure: CRM architecture, data quality, enrichment pipelines, and workflow automation. Only then do we scale volume.

Automation Compounds

The first month saves 5 hours per week of manual research. The second month saves another 5 hours as you automate follow-ups and data entry. By month 3, you've freed up 25+ hours per week that your team redeploys to relationship-building and closing. That's 100+ hours per person per year.

Quality Beats Volume

Every case study started with better targeting (ICP, signals, intent) before volume. The result: 2-3x the reply rates and 2-3x the conversion rates of standard outreach. Reaching fewer, better-qualified prospects generates more pipeline than reaching thousands of random contacts.

Deliverability Is Non-Negotiable

If your emails land in spam, volume doesn't matter. Every engagement audits domain reputation, authentication (SPF/DKIM/DMARC), and email sending practices. Fixing deliverability from 65% to 97% alone can double pipeline.

Founder Leverage Is the Real Win

Case Study 3 freed up 30+ hours per week of founder time. Case Study 1 freed up the founder from manual outreach entirely. Every engagement is designed to free up your highest-leverage person—usually the founder—to focus on closing deals and building product, not running GTM.

Data Drives Iteration

Every campaign produces a trove of data: reply rates by message type, conversion rates by company size, best response times. Using this data to iterate weekly compounds results. Case Study 2 went from 12% to 24% reply rates by analyzing what worked and optimizing messaging.

The Typical Engagement Timeline

What you can expect from week 1 through ongoing support. Every engagement follows this pattern: audit → foundation → execution → handoff.

1

Week 1: Kickoff & Audit

  • Initial call: goals, current stack, team structure, biggest blockers
  • Audit existing CRM, sales process, tech stack, current pipeline
  • Identify quick wins (data cleanup, deliverability fixes, simple automations)
  • Map ICP and target customer profile
  • Deliverable: Audit report and 30/60/90 plan
2

Week 2-3: Foundation

  • CRM architecture design (account structure, deal stages, custom fields, workflows)
  • Enrichment pipeline design (data sources, enrichment order, quality thresholds)
  • Target account list building (100-1000 accounts depending on motion)
  • Email and messaging framework (value props, personalization hooks)
  • Deliverable: All infrastructure diagrams, documentation, initial setup complete
3

Week 4-8: Implementation & Launch

  • CRM configuration and workflow setup (Salesforce/HubSpot)
  • Enrichment automation deployment (Apollo, Clay, n8n)
  • Email sequences and AI personalization live
  • Multi-channel campaigns launching (email, LinkedIn, phone)
  • Team training on new processes and systems
  • Deliverable: First campaigns live, initial data flowing, team trained
4

Week 9-12: Optimization & Handoff

  • Weekly results review: what's working, what needs iteration
  • Message and sequence optimization based on response data
  • Scale campaigns to full prospecting volume (500-5000+ accounts)
  • Build dashboards and reporting (no more manual status updates)
  • Final team training and playbook documentation
  • Deliverable: Fully documented, repeatable system your team owns
5

Month 4+: Optional Ongoing Support

  • Monthly advisory calls to review results and evolve strategy
  • Support for new campaigns, new target segments, or scaling
  • System upgrades (new tools, AI agents, signal-based automation)
  • Quarterly business reviews on pipeline, CAC, and GTM health
  • Transition to embedded or full-time if scaling requires it

Why These Results Compound

Infrastructure Multiplies Leverage

Once systems are in place, every hour invested in prospecting becomes 3-5x more effective. Founder frees up 30+ hours per week. SDRs shift from data entry to relationship building. This multiplier compounds every month.

Quality Targeting Beats Volume

Focusing on high-intent prospects, decision-makers, and companies showing buying signals gets 2-3x the reply rates and conversion. This means you generate more pipeline with fewer touches, not more touches to more people.

Unit Economics Transform

Cost per meeting drops from $1000+ to $100-200. This isn't just nice—it means you can scale profitably. You generate more pipeline, faster, at lower cost. Every additional campaign compounds, not diminishes.

Team Ownership and Scaling

The goal is always handoff. Your team owns the system, understands how it works, and can evolve it. You don't become dependent on external support. The infrastructure becomes your competitive advantage—harder to replicate than any one person.

Frequently Asked Questions

Are these real case studies or examples?

These are real results from actual engagements across 10+ companies generating $100M+ in pipeline. Company names and specific details have been anonymized to protect client confidentiality, but the numbers, timelines, and methodologies are real. Every metric mentioned—pipeline value, conversion rates, cost per meeting, timeline—is based on actual results achieved.

How quickly can I expect to see results?

Most engagements show initial momentum in 30-60 days. The first 30 days focuses on infrastructure setup, CRM architecture, and launching initial enrichment and sequencing. By day 60, you typically have 10-30 qualified opportunities in motion. By day 90, you have a fully documented, repeatable system. Results depend on commitment to implementation, CRM access, team participation, and decision-making velocity.

Do these results apply to my specific industry or company size?

The case studies span pre-Series A startups through Series B companies, bootstrapped operators through well-funded teams, and multiple industries (B2B SaaS, enterprise software, B2B services). The core principles—infrastructure automation, enrichment waterfalls, AI personalization, signal-based targeting—work across all these stages. Your specific results depend on starting point, sales motion, and execution, but the methodology is proven across diverse markets.

What's the biggest challenge most companies face when starting GTM engineering?

Three challenges consistently emerge: First, most founders/sales leaders are buried in manual work and don't have time to build infrastructure. Second, teams lack a clear ICP and targeting strategy, leading to waste. Third, current CRM and tooling is a mess, making data-driven decisions impossible. A GTM engineer fixes all three by building systems that work without constant manual feeding.

How much does a GTM engineer cost versus the results shown?

Fractional GTM engineering costs $3K-$9K per month. In Case Study 1, $2.4M pipeline was generated in 90 days on a Core engagement ($5.5K/mo), so 90 days of cost was roughly $16.5K for $2.4M pipeline—a 145x ROI. In Case Study 2, 3x pipeline scaling on a $9K/mo Embedded engagement generated millions. The infrastructure built compounds over time, multiplying ROI in subsequent months and years.

What happens after the engagement ends?

GTM engineering is designed for handoff. Every engagement produces documented playbooks, architecture diagrams, training sessions, and dashboards so your team owns the system long-term. Most clients either keep the system running independently or maintain a small advisory engagement to evolve the system as the company scales. Some scale to embedded or full-time, but the infrastructure becomes self-service for your team.

Can these results scale to larger enterprise sales teams?

Yes. These case studies start with small teams (8-30 people), but the same infrastructure scales to 50+ person sales organizations. The difference is complexity: larger orgs have multiple segments, longer sales cycles, and more tool integration. A GTM engineer scales the playbook, automates signal-based workflows, and builds AI agents to handle increasing volume without proportional headcount growth.

What's the most important metric in GTM engineering?

Cost per qualified meeting is the north star. Every other metric (pipeline value, reply rate, conversion) is a derivative of this. If you can lower cost per meeting from $1K to $100 while maintaining quality, you've won. That's what the infrastructure does—it automates the expensive manual work (research, list building, enrichment, initial outreach) so your sales team focuses on the human part (discovery, objection handling, closing).

Ready to See These Results for Your Business?

Every company starts with a different challenge, but the approach is the same: audit your current GTM infrastructure, identify the biggest blockers, and build a system that compounds. Let's talk about where you are and what's possible.
