Most GTM stacks don't behave like a system

Your team bought Clay, Gong, Apollo. But leads still leak, data doesn't sync, and AI tools sit unused.

Adding AI to broken infrastructure makes problems worse, faster. The constraint isn't technology. It's the plumbing connecting it.

The infrastructure layer

  • Data Scraping, enrichment, normalization, scoring
  • Routing Assignment rules, ownership, SLAs, triggers
  • Execution Tasks, sequences, follow-ups, playbooks
  • Visibility KPI dashboards, operating metrics, pipeline reports
  • Reliability Documented workflows, ready for handoff
  • Optimization Stack consolidation, cost reduction

Clean pipelines your AI tools can use. Workflows that run on their own. Systems your next hire inherits.

What changes after ATL

Before
  • Lead assignment takes hours, deals slip through
  • Reps ask "what do I do next?" every time
  • Forecasts built on guesswork from stale data
  • New hires spend months figuring out fragmented systems
  • AI tools sit unused because the data is too messy
After
  • Sub-5 minute routing, zero leakage
  • Automated playbooks trigger by deal stage
  • Real-time dashboards with reconciled forecasts
  • New hires inherit documented, working workflows
  • AI integrates with clean, structured data

What a sprint typically ships

In a sprint we deliver 3–6 production workflows from this menu, tailored to your stack and priorities.

Lead Lifecycle & Routing

Enrichment, deduplication, owner routing, speed-to-lead alerts, SLA enforcement, source normalization, lead governance.

Meeting to Revenue

Booking triggers, pre-call briefs, follow-up task automation, stage movement rules, post-call summaries with next steps.

Outbound Engagement

List building, scoring, sequencing gates, trigger-based outbound, signal-based personalization at scale.

Pipeline Hygiene & Visibility

Stale opportunity nudges, stage validation, auto-generated weekly KPI packs, executive dashboards.

Reliability & Governance

Workflow mapping, monitoring, documentation, ownership models, handoff playbooks.

Custom Builds

Product signal scoring, multi-product routing, custom data pipelines, competitive intelligence, TAM analysis, attribution.

Low risk start, fast delivery

Two main ways to engage. Both designed so you see progress fast and never feel locked in.

Week 1

Design + Alignment

Map current state, prioritize outcomes, design workflows.

Week 2

First Workflow Live

See real progress. Course-correct early if needed.

Weeks 2–5

Build & Ship

Incremental delivery with weekly check-ins.

Final Week

Handoff

Documentation, training, and a roadmap for what comes next.

Progress, not promises

First workflow ships by week 2. You see real output before you're halfway through the engagement.

Weekly check-ins

Course-correct or stop if it's not working. No six-week reveal where you hope it all came together.

Built for handoff

Every workflow comes with documentation, video walkthroughs, and a trained internal owner. We leave, it keeps running.

Other ways to work together

Not every engagement is a sprint. We flex to what you actually need.

Flexible Hourly Support

Not-to-exceed blocks with weekly priorities. Good for targeted fixes, ongoing tweaks, or when you need a specific workflow built without a full sprint commitment.

Fractional GTM Engineer

1–2 days a week, embedded with your team. Keeps your systems running and evolving until you hire full-time, or alongside your ops team for extra technical depth.

Real outcomes from real engagements

Infrastructure work shows up in the numbers. Here's what it looked like for two recent clients.

Outbound Infrastructure

Gather

Formerly BeHeard Labs. First GTM hire starting. Needed outbound systems operational before validating headcount.

24hr → 4minlead response time
25xdaily personalized emails (200 → 5,000)
1,200qualified leads per month

"Eric and ATL created an incredible infrastructure we are using today to find prospects, enrich contacts, and send personalized emails at scale."

Jay Flaherty, Head of GTM
TAM Analysis + Scoring

Dyneti

Standard databases couldn't capture niche B2B buying signals. Needed custom TAM analysis beyond Apollo and ZoomInfo.

"The mixture of custom scrapers and lead scoring provided the best picture of our market we have seen."

Julia Zheng, CEO

Is this a fit?

Seed – Series B

First sales hire incoming or founder-led sales hitting limits. You need systems before you need headcount.

RevOps / GTM Leaders

Strategy is clear. Bandwidth or technical depth to build is missing. You know what you want, you need someone to ship it.

Founder + CRO

Revenue growing, team expanding. Current "systems" are spreadsheets and manual processes that won't survive the next hire.

Not a fit: teams without an internal owner, or orgs looking for someone to run their reps or write their messaging.

Common questions

We work with what you have. If we recommend new tools, they'll be the smallest set needed to get the job done. We often reduce spend by consolidating and optimizing underused tools.
We work alongside your team to expand capabilities and ship faster. Not replacing anyone. Augmenting bandwidth and technical depth.
We're not replacing the hire. Hiring and ramping takes 6+ months. We build the foundation in 4–6 weeks so your first RevOps hire inherits working systems instead of starting from zero. Higher success rate, faster impact.
No. We build systems, not fill quota. It's up to your team to maintain and expand the foundation we build, A/B test copy, and continue upskilling reps. Execution support can be scoped separately.
Happy to connect you with previous customers. We currently operate primarily on referrals, and we may ask you to be a reference in the future.
