Think of it as a senior marketing strategist built into your business. We install it, trained on your brand and built on 25+ years of B2B and founder expertise. You own it permanently. It runs whether we're involved or not.
Most businesses buy marketing tools.
We give you a marketing mind.
Most AI tools give you a blank slate. ShoestringGPT gives you a strategist.
The name is a deliberate play on ChatGPT - but instead of generic output, it has 25+ collective years of B2B marketing and founder expertise baked into it. It doesn't produce content on demand. It thinks, advises, reviews and coaches. It is the marketing mind at the heart of everything we install for you.
Catches voice drift. Flags anything off-brand. Nothing leaves your marketing mind until it sounds like you.
Before every meeting, it pulls the prospect's profile, surfaces their likely pain points, and tells you exactly how to pitch them.
Reviews your DMs and emails before you send them. Tells you what's landing and what to rewrite.
Tells you what's working, what to fix, and what to prioritise - based on your actual results, not generic best practices.
Every piece of content that flows through your marketing mind is reviewed by ShoestringGPT before it goes anywhere.
Trained on your brand from day one. Every edit, every approved piece, every conversation makes it sharper.
If your marketing stops when someone leaves or your agency churns, you don't have a system. You have a dependency. The worst part isn't the cost - it's knowing you'd have to start from zero if anything changed. We fix that permanently.
"We were paying £3,500 a month for someone to schedule posts and write reports. Shoestring built us an engine that does all of that and more - for a fraction of the ongoing cost."
Early client · B2B Consulting · LondonTraditional agencies bill for hours. When you leave, you leave with nothing - no workflows, no automations, no IP. Just a gap in your budget and a blank slate to start over.
Outreach, content, follow-ups - the moment your team gets busy or your agency drops a ball, everything stalls. There's no engine running in the background. There's just silence.
Anyone can open ChatGPT. What they can't do is get 25+ years of B2B marketing and founder expertise - trained specifically on their brand, clients and voice. That's the gap ShoestringGPT fills. Not generic AI. An opinionated marketing strategist that knows what actually works in B2B.
AI has made content, outreach and reporting ten times faster to produce. Agency retainers haven't moved. You're paying full price for work that now takes a fraction of the effort.

Future-ProofEvery one of these modules runs inside your marketing mind. Choose two to start - or build the full engine. The more modules you install, the more powerful it becomes.
Designed to be low-friction. You don't need to be technical - we handle everything and only pull you in when a decision genuinely needs your input. Minimal meetings, maximum output.
One structured session. We get under the hood of your business - brand voice, ICP, existing tools and goals. No technical knowledge needed from you. We do the mapping; you approve the direction.
We install everything. Every workflow configured, every integration connected, every trigger tested. You get weekly async updates - no meetings unless you want them.
You get everything. A full walkthrough of your marketing mind, a Loom training library, all credentials transferred to your accounts. Everything documented so you can run it confidently from day one - or hand it to someone on your team.
Optional - and popular. We keep an eye on everything: monitoring performance, catching issues early, and optimising systems as your business grows and tools evolve.
At the end of 90 days, your marketing mind is yours. Whether you stay with us for maintenance or not - it runs in your tools, under your credentials, independently of us.
No endless briefing sessions. No chasing updates. No wondering what's happening with your money.
We map your marketing gaps, identify the highest-impact modules and confirm this is the right fit. You'll leave with a clear picture of what your marketing mind would look like - whether you go ahead or not.
Within a week of onboarding, you'll have a clear map of every workflow we're building - the tools involved, the triggers, and the expected outcomes.
Mostly async - we work, you get weekly updates. We only pull you in when a decision genuinely needs your input. No micromanagement required on either side.
Your tools, your accounts, your credentials, your marketing mind. We're on standby if you need us - but you won't have to. That's the point.

"Within three weeks of handover, our review count had tripled. I hadn't done a single thing. The system just ran."
"We were spending $4K a month on an agency and getting maybe three hours of actual work. This gave us a real engine we own outright."
"The handover was the bit I was dreading. But the documentation was so thorough I understood exactly how everything worked on day one."
What is ShoestringGPT?
ShoestringGPT is the AI marketing strategist at the heart of every system we build. The name is a deliberate play on ChatGPT - but instead of generic AI output, it has Shoestring's 25+ collective years of B2B marketing and founder expertise built directly into it. It reviews content before it goes out, preps your sales calls, coaches your outreach, advises on strategy, and runs a quality gate over everything your system produces. It's trained on your brand during onboarding and gets sharper the longer you use it. You own it permanently when your system is handed over.
How is this different from just using ChatGPT or another AI agent?
Anyone can open ChatGPT. What they can't do is access 25+ years of B2B marketing and founder expertise - trained on their specific brand, clients and voice. ShoestringGPT is opinionated: it knows what messaging converts in B2B, how to position a founder, when to push and when to pull back. That knowledge comes from real experience, not internet training data. Most AI tools give you a blank slate. ShoestringGPT gives you a strategist.
Do I need to have Make.com or other tools set up already?
No. Part of onboarding is setting up every account you'll need. We walk you through what's required, what it costs (typically under $100/month in tool fees), and handle all configuration ourselves. You'll finish with a Make.com Toolbox that's yours to keep and run independently.
What happens if something breaks after handover?
Every package includes a 30–60 day post-handover support window - we're there if anything goes sideways during the transition. Clients on a maintenance plan also get ongoing monitoring and proactive fixes before issues surface.
How much of my time does this actually take?
We've designed the build to be deliberately low-friction. Most clients invest 3–5 hours total across the entire project - primarily in the onboarding session and the handover walkthrough. Everything in between is async on our side.
Will the content actually sound like us?
Yes - and this is the part we take most seriously. Onboarding includes a deep-dive into your brand voice, tone, audience language and examples you love. Every AI prompt is trained against this profile before a single piece of output is approved for use.
Can I add modules after the initial build?
Absolutely. Most clients start with 2–4 modules and expand as they see results. Module add-ons after handover are priced individually and integrate cleanly into your existing system - no starting from scratch.
