What we build

Growth systems,
not campaigns.

What you get

Two services. One engine.

Most engagements bundle the campaigns and the infrastructure into a single program. They're also available separately for teams that already own one half.

Outbound engine

01

Cold email campaigns

Multi-channel, hand-tuned, weekly-optimized

We design, deploy, and run multi-step cold email programs that turn cold prospects into qualified meetings. Built around your ICP, written by humans, tuned weekly against live reply data.

Includes

  • ICP research, list build, and audience scoring
  • 1-to-1 personalization at the individual level — no mail merge
  • Multi-step sequences with reply-classification routing
  • Weekly campaign tuning against live performance data
  • Reporting cadence aligned with your sales team

Inbox infrastructure

02

Deliverability engineering

Multi-domain, monitored, reputation-first

The plumbing under every campaign. Multiple sending domains warmed in parallel, authentication tuned for inboxing, and continuous monitoring so a single misfire doesn't burn your reputation.

Includes

  • 6–12 sending domains warmed in parallel from day one
  • DKIM, SPF, and DMARC configured per domain
  • Spam-trap and bounce monitoring with alerting
  • Sending pool management & rotation logic
  • Quarterly deliverability audits

The comparison

GBV vs. the alternatives.

Same outcome, three very different paths. Here's the mechanical difference between building it yourself, hiring an agency, and engaging GBV.

How we work

The engagement model.

How GBV partners with B2B teams. Not a retainer. Not an agency black box. A scoped, documented build with a clean handoff path.

Embedded operators

Every engagement is staffed by a senior outbound operator plus a deliverability engineer. You meet them on kickoff and they stay with you the entire engagement.

Fixed engagement length

We don't sell open-ended retainers. Engagements are scoped at 90 or 180 days. At the end, the system is fully documented and handed to your team — or we keep operating it.

Everything is yours

The data, the workflows, the domains, the sequences, the dashboards. No vendor lock-in. We hand off written runbooks so your team can keep running the engine after we leave.

Fit check

Who this is for.

We're selective about engagements — both because we operate them deeply, and because email infrastructure isn't the right answer for every B2B company.

Built for you if…

  • You have a validated offer with paying customers
  • Your ACV is high enough that one closed deal pays for the engagement
  • Your buyers can be reached over email and LinkedIn
  • You can move on qualified meetings within 48 hours
  • You want infrastructure you own, not a campaign you rent

Not a fit if…

  • You're searching for product-market fit and don't have a defined ICP
  • Your ACV is under $1k with high churn
  • Your buyer is consumer or hyper-local
  • You want a one-month campaign and a pile of leads
  • You're not ready for your sales team to handle 20+ new meetings/mo

Services FAQ

Pricing, scope, and what to expect.

Engagements are scoped as a fixed fee tied to the program (not an hourly retainer). The 90-day engagement includes the full build plus the first weeks of operation; the 180-day engagement extends the operating period. We share the specific number on the strategy call after we understand your ACV, ICP, and goals.
