We Build Cold Outreach Systems That Keep Your Calendar Full – in 21 Days or Less.

Your Outbound Isn't Broken. Your Infra Is.
Most teams jump to "send more emails" instead of fixing the foundation. Deliverability, domain setup, data quality, persona fit and tool configuration are 80% of outcome.
Without proper infra, you burn domains, waste money on tools, and think outbound "doesn't work."
of cold emails never reach the inbox when infra isn't set up correctly
higher reply and meeting rates when teams invest in proper infra
stacks are over-tooled and under-designed
The Outbound Stack That Scales With Your ARR.
Choose tools and budget based on your stage – not hype.
Stage 1: 0–$1M ARR – Launch Stack
Budget: $150–$400/month – founder-led, lean and simple.
"Ship campaigns fast, collect signal, don't overbuild or overspend."
Stage 2: $1–$5M ARR – Growth Stack
Budget: $800–$1,500/month – automate repeatable tasks.
"Start layering RevOps and SDRs, centralise data, and scale what already works."
Stage 3: $5–$20M ARR – Scale Stack
Budget: $3,000–$8,000/month – RevOps becomes a team.
"Multi-channel, signal-driven outbound with full GTM visibility and RevOps ownership."
We help you decide what belongs in your stack at your stage – and then we build it.
From Random Tools to a Clean, Modern Outbound Stack.
Grand Slam Tech audits your ARR, motion, ICP and current tools. Then designs a stack mapped to your stage (0-1M, 1-5M, 5-20M) and your buying motion.
Focus is on simplicity, clarity and throughput, not buying every shiny tool.
We don't just recommend tools – we architect systems that create pipeline.
Tech stack selection (email, CRM, data, enrichment, validation, tracking)
Domain and inbox architecture (root + subdomains, DNS, routing)
Warmup and deliverability monitoring
Lead sourcing and enrichment workflows
Sequence frameworks and base messaging (for multiple personas)
CRM + pipeline structure tuned for outbound motions
Dashboards / reports for founders, GTM and RevOps
