GrowthMatic, a mid-market B2B SaaS company, was spending 30+ hours per week manually creating, scheduling, and reporting on marketing campaigns across LinkedIn, email, and Google Ads. Their team of 4 marketers was overwhelmed managing campaigns for 80 active clients, leading to inconsistent output quality, delayed campaign launches, and a 3-month backlog of client requests. The CEO needed to double the client base without doubling headcount.
We built an AI-powered marketing automation platform that generates campaign content using fine-tuned GPT-4o models trained on the client's historical high-performing campaigns, schedules and publishes across all channels via unified API integrations, monitors performance in real-time, and automatically adjusts budgets and targeting based on ML-driven optimisation rules. The platform handles the entire campaign lifecycle from brief to final performance report — with humans approving the strategy and reviewing the output, but no longer doing the execution work.

“We went from a 3-month campaign backlog to same-week delivery. The AI doesn't just automate — it actually improves the quality because it's drawing on every successful campaign we've ever run. We've taken on 60 new clients in 6 months without a single new hire on the marketing team.”
— Sarah Chen, CEO, GrowthMatic
GrowthMatic grew from 80 to 140 active clients within 6 months of launch without expanding their marketing team. Campaign quality scores improved as the AI learned from performance data. The platform has since been white-labelled and sold to two of GrowthMatic's agency partners, creating a new revenue stream worth $40K/month.
