Happy AI Hump Day - It's a Use Case Wednesday

Published 14 days ago • 1 min read

Wednesday · April 1, 2026 · Issue #008

Every Wednesday I break down a real AI use case — a specific business problem, the tools that solved it, and the numbers that prove it worked.

Today: how a mid-size B2B company replaced $180,000/year in sales and marketing consulting with an AI stack that costs less than $700/month.
🎯 The Problem

A 45-person B2B software company was spending $15,000/month on a sales and marketing agency. The deliverables: a weekly content calendar, monthly lead prospecting lists, ad creative updates, and a quarterly sales strategy review. Response times were slow. The content never quite sounded like them. And the lead lists were stale by the time they arrived.

The VP of Sales gave the team 90 days to build an internal AI stack that could match or beat the agency's output. Here's what they built.
🤖 The AI Stack They Built

🚀 Apollo.io — $49/mo ✦ Partner

Replaced the agency's monthly lead prospecting. The sales team now pulls a fresh, hyper-filtered list of 500 qualified prospects every week using Apollo's 275M+ contact database. Each contact has verified email, phone, and LinkedIn. What took the agency 3 weeks now takes 20 minutes.

📢 AdCreative.ai — $29/mo ✦ Partner

Replaced the agency's ad creative production. The marketing team generates 30 on-brand ad variants per campaign in under 15 minutes. Previously the agency delivered 5 variants every 3 weeks. Performance-optimized output at 1/10th the cost.

✍️ Jasper AI — $49/mo

Replaced the agency's weekly content calendar. One content manager now produces 12 pieces of long-form content per month — blogs, LinkedIn posts, email sequences — in the company's brand voice. The agency was producing 4.

✨ Gamma — $15/mo ✦ Partner

Replaced the agency's quarterly strategy decks. Any team member can now build a fully designed, executive-quality presentation in under 20 minutes. What used to take the agency two weeks and a revision cycle now happens same-day.

Tuesday · April 15, 2026 · Issue #017 Stop downloading tools.Start hiring agents. Most AI tools do one thing. You open them, tell them what to do, get an output, and close them.

Monday · April 14, 2026 · Issue #016 You don't have an AI problem.You have a decision problem. There are 50,000+ AI tools in the market right now. That number grows by hundreds every month. And what we're hearing from business professionals everywhere — on LinkedIn, in Slack channels, in boardrooms — is not excitement. It's exhaustion. The tools aren't the problem. The signal-to-noise ratio is the problem. Nobody has time to evaluate 50,000 options. Nobody should have to. That is exactly why...
