What we do
3DGE builds and operates B2B customer proof programs designed to shorten sales cycles and increase win rates. The core deliverable is not a collection of individual case studies but an end-to-end proof infrastructure. encompassing content strategy, case study production, sales enablement activation, and ongoing program management. that compounds in value as the client's customer base grows.
Engagements follow a structured three-phase model. The Audit (from €950) is a diagnostic engagement that maps a client's existing proof assets against their ICP segments, identifies gaps, and produces a prioritised action plan. The Sprint (from €4,500) is an intensive build phase that delivers interview frameworks, an operating system, tooling configuration, and an activation playbook. the complete engine required to run a repeatable proof program. The Retainer (from €1,500/month) keeps the engine running: monthly case study production, proof asset activation, program management, and continuous improvement, with every new customer win layering onto an expanding sales-ready library. On-demand case study production (from €800) is also available for one-off needs without a full program commitment.
Content production spans written case studies and derivative assets (social snippets, one-pagers, email proof points) structured and tagged for sales team retrieval. Sales enablement is embedded throughout. assets are built to be found and used by sales at the right moment in the buyer journey, addressing the common failure mode where proof exists but is never deployed. The team model is lean by design: clients work directly with the founder, supported by a vetted network of specialist case study writers and program managers brought in as needed.
Our approach
Three-phase proof program methodology: Audit (map proof gaps and ICP alignment), Sprint (build the proof infrastructure, interview frameworks, operating system, tooling, activation playbook), Retainer (run and compound, ongoing production, program management, sales activation). Designed to be repeatable, scalable, and compounding over time.
How we work
Retainer
Ongoing monthly engagement with fixed scope and regular delivery. Typically minimum 3 months.
Project-based
Fixed-scope, fixed-fee engagement with defined deliverables and timeline.
Workshop or sprint
Intensive short-format engagement — typically 1 to 5 days — producing a specific output.
Hybrid
Combination of engagement models — typically a project fee plus ongoing retainer.
Consulting day rate
Advisory engagement billed per day or hour. Flexible scope and timing.

B2B companies have happy customers but no structured system to capture and activate proof for sales.
A repeatable proof program is built that compounds with each new customer win and shortens sales cycles.
Marketing teams produce case study assets that sales teams never use, wasting effort and budget.
Proof assets are structured and activated so sales teams can deploy them effectively in deals.
Competitors with inferior solutions are winning deals by presenting stronger, clearer proof.
B2B companies gain a structured proof program that closes the proof gap and improves win rates.
Proof programs exist on paper but in practice consist of only a few assets sitting unused in a shared folder.
A scalable proof infrastructure is built with strategy, interview frameworks, tooling, and activation playbooks.
Who we work with best
B2B companies, from early-stage founders with a handful of customers to growth-stage marketing leaders and CMOs, who struggle to capture, structure, and activate customer proof in a way that supports the sales process. Particularly relevant to lean marketing teams where proof assets exist but are unused by sales.
