TL;DR
One operator, one contract quarter, one national growth hub for a venture program (foundation.ventures) building on a global technology platform. Documented results: ~2,585 founders outreached across two outreach funnels, 170+ founder video calls, 211 long-form content pieces against a 60-piece KPI (a 3.5× over-delivery, plus 61 custom graphics), 1.74M+ ad impressions, and two hackathons drawing 160+ attendees and 84 project submissions in total (48 qualified in the flagship event).
The engagement
foundation.ventures runs venture programs that source and accelerate startup founders for a global technology-platform ecosystem. GTM Stacker was contracted to run its UK growth hub: find founders, get them on calls, move them into the program's funnel, and build the content and event presence around it.
The brief spanned four functions that would usually be four hires — outbound/sourcing, community and calls, content production, and event delivery — on a single-operator contract.
The system
1. Founder sourcing and outbound
- Two parallel outreach funnels with separate ICPs and messaging: an agency-partnership funnel (1,365 founders outreached) and a venture-scout funnel (1,220 founders outreached) — ~2,585 in total.
- Enrichment and prospecting handled by custom AI-built tooling: sourcing, qualification and personalisation at a volume one person could not sustain manually.
- 170+ founder video calls booked and held across the quarter — the pipeline's conversion point.
2. The content engine
- Contract KPI: 60 long-form content pieces for the quarter.
- Delivered: 211 long-form pieces, plus 61 custom graphics, 15 ad creatives, 28 lead magnets and 6 videos.
- Content was fed directly by what the 170+ calls surfaced — real founder questions, objections and language.
3. Paid amplification and the hackathons
- 1.74M+ paid ad impressions across TikTok (~1.38M) and Facebook (~365k) supporting the sourcing funnels.
- Delivered two hackathons for the program: 160+ attendees and 84 project submissions in total, with 48 qualifying in the flagship event's qualification round, followed by national-round selection.
How one operator carried four functions
The multiplier was AI-built internal tooling. Enrichment, outreach orchestration, research briefs and reporting ran on custom workflows built by directing AI coding agents — with model routing chosen per task (high-reasoning models for research and copy, cost-efficient models for bulk steps). That kept the cost per sourced founder far below what a commercial SaaS stack plus an agency team would have charged for the same volume.
Outcome
On the content KPI the engagement over-delivered 3.5× — 211 long-form pieces against a KPI of 60 — with the quarter's work documented line-by-line in a performance sheet shared with the client. The same sourcing-to-content machinery now forms the template for GTM Stacker's startup engagements.
