Pipeline without the headcount.AI-native growth systems for startups and venture programs.
GTM Stacker is the growth-systems practice of Theo Popov: enrichment, outbound, content engines and the internal tooling behind them — researched deeply, built AI-native, run capital-efficiently.
Documented delivery for a venture-program client: 170+ founder calls booked in one contract quarter.

Proof, not promises
Three bodies of work. Every number traces to source records.
A venture program’s national growth hub
~2,585 founders reached, 170+ founder calls, 101 long-form pieces against a 60-piece KPI, 1.74M+ ad impressions — delivered in one contract quarter by one operator with AI-built tooling.
Read the case studyAn 11-site business run on custom ops systems
Co-founded and scaled a hospitality group to 11 locations on a two-warehouse ERP model: stock variance 4–7% → ~0%, reporting lag 17 days → 1 day, related payroll cut ~14%.
Read the case studyAn agent-native registry built for AI search
A machine-readable media property — llms.txt, OpenAPI, MCP server, JSON-LD, IndexNow — verified by 2,793 automated consumer checks. Live on this domain.

Not an agency with layers of account managers, and not an AI tool you still have to drive. GTM Stacker is a hands-on practice: deep research, AI-native builds and direct delivery — systems you own, at a fraction of the usual SaaS and headcount cost.
Three kinds of systems, one principle: small teams should be able to generate pipeline without proportional headcount.
Enrichment & outbound systems
The pipeline engineICP research, waterfall enrichment and multi-channel sequencing — the machinery that reached ~2,585 founders and booked 170+ calls for a venture program in one quarter.
AI-built internal tooling
The cost leverCustom workflows, scrapers and dashboards built by directing AI coding agents, with deliberate multi-model routing to minimise cost per outcome — replacing $2–7k/mo of commercial GTM SaaS.
Content engines
The authority layerResearch-heavy long-form content and custom visuals, engineered to convert — 101 long-form pieces and 61 graphics delivered against a 60-piece contract KPI.
Every system ships with documentation and reporting. You own all of it.
From first call to a running system
You spend 30 minutes. I handle the rest.
Scoping call
30-min callYou explain the product, the market and what a win looks like. I map where the pipeline actually leaks — top of funnel, conversion, data or reporting.
Deep research
2–3 daysYour niche, buyers, competitors and existing stack. What problems your market searches for, what language it uses, and what your current tooling really costs.
System design
Async reviewA concrete build plan: what to build, what to buy, and the cost per outcome of each option. You approve the design before anything is built.
Build & launch
Days, not monthsI build the system — enrichment, outbound, content engine, dashboards — using AI coding agents where they beat off-the-shelf SaaS on speed and cost.
Operate & compound
OngoingI run the system or hand it over — with documentation, reporting and optimisation based on what actually converts, not what gets likes.
Systems ship in days, not quarters — and everything I build stays with you.
