We build your commercial stack. You hit the targets you promised.

Eight weeks. CRM, reporting, email infrastructure, lifecycle automation, and a 90-day GTM playbook - built and handed over before your first growth hire arrives.

The right growth engine for your model

Before we build anything, we identify which channel fits how your customers actually buy. Most startups get this wrong and spend six months finding out.

Commercial stack built in 8 weeks

CRM, reporting, lifecycle flows, and email infrastructure - live and working before you hire your first growth person.

Investor-ready reporting from day one

CAC by channel, funnel conversion, retention cohorts. Pull it up in 30 seconds. Walk into any board meeting with confidence.

Lifecycle emails that actually land

Sending infrastructure warmed, DNS verified, flows deployed. Open rates that reflect your product - not your spam score.

First we find your growth engine. Then we build the infrastructure to run it.

Most startups default to the wrong channel. We identify the growth motion that fits your business model before we build a single workflow.

01AI-assisted

Data and reporting

GA4, CRM, ad accounts and Stripe wired into a single Looker Studio dashboard. Five views: acquisition, funnel, retention, LTV, weekly digest. You know what's working before you spend another pound.

02

CRM and pipeline

HubSpot architecture built to your actual sales motion — marketplace, SaaS, or consumer. Deal stages, contact properties, lead routing, sales sequences, ICP documentation.

03AI-assisted

Lifecycle and retention

4–5 automated email flows live in 8 weeks: onboarding, trial conversion, win-back, referral. Copy generated and QA'd, triggers configured, deployed into warmed infrastructure.

04AI-assisted

Acquisition and GTM

UTM taxonomy, attribution model, channel experiment log, and a 90-day acquisition playbook built around your growth engine — not a generic channel list.

05AI-assisted

Email deliverability and sending infrastructure

Multiple sending domains configured, DNS records verified, inboxes warmed via Smartlead before your first email sends. Your lifecycle flows land in the primary inbox — not spam. Standard on every sprint.

06AI-assisted

SEO and organic growth

Keyword strategy mapped to your ICP's search intent. Site architecture audited. Content framework built so your team can execute. Organic as a compounding channel, not an afterthought.

07AI-assisted

AI adoption and workflow automation

We identify where AI can replace manual work in your commercial operation (outreach, enrichment, reporting, content, customer comms) and build the automations. Clay for enrichment. n8n for workflow orchestration. AI agents for repetitive tasks. Your team spends time on judgment, not admin.

Eight weeks. Everything built. Ready to hand off.

Delivered faster because AI does the heavy lifting.

Most consultants take 12–16 weeks to build what we deliver in 8. The difference is the AI tooling we've built to do in hours what used to take days.

AUDIT

Commercial gap analysis in hours, not days

Your intake data - GA4, CRM status, ad accounts, email platform - runs through our AI audit engine and produces a structured gap analysis before the first strategy session. You get diagnosis on day 1, not week 2.

COPY

Lifecycle email copy generated and QA'd

Every lifecycle flow we build uses AI to generate copy variants matched to your tone of voice and ICP. We edit and approve - you get tested, on-brand emails deployed in days, not weeks of back-and-forth.

REPORTING

Monthly reports auto-generated, not manually built

Your monthly performance report pulls automatically from your Looker Studio dashboard, identifies the top three changes from the prior month, and flags any risks. We add strategic commentary. You get it in your inbox every first Monday.

PLAYBOOK

GTM experiment backlog generated from your product brief

Channel hypotheses, prioritised experiment backlog, and budget allocation model — generated from a structured brief about your product and ICP. What used to take a week of strategy writing takes 48 hours.

The AI handles the production. We handle the judgment. You get both.

All options have their place. Stackd is specifically for the 8 weeks between raising and hiring.

Nine years in the commercial seat.

Stackd is run by Ludo Martin — operator, not advisor.

I've spent nine years as the commercial operator inside high-growth startups — not advising from the outside. First growth hire at marketplace businesses, retention lead at one of Europe's fastest-scaling delivery companies, co-founded my own incubator-backed startup with full P&L ownership, and most recently 600%+ revenue growth at a consumer sports business while opening two US markets.

I've built this stack under pressure, with real consequences. I know exactly what breaks first and why. Stackd is what I wish had existed every time I joined a company with nothing in place.
