Every number below is verifiable. We work with clients who give us full access to their data — and data doesn't lie. No case study with numbers rounded "to look credible": what you're reading is real data, with the exact reporting period.
An active e-commerce store with decent organic traffic but a conversion rate under 1.2% — average for the sector, but well below its potential. The problem wasn't traffic: it was what happened after the click. We completely redesigned the mobile UX (which drove 82% of traffic), implemented email marketing with behavioural segmentation on Klaviyo, and restructured Meta Ads with a full-funnel approach — top, mid and bottom of funnel with dedicated creative for each stage. In 9 months: +262% revenue, CPA down 34%, conversion rate up from 1.2% to 2.27%.
A professional firm with zero digital presence, relying entirely on word of mouth for client acquisition. We built an acquisition funnel on Google Ads with very high-intent keywords, A/B-tested landing pages (11 variants over 6 months) and automated nurturing on HubSpot with behavioural scoring. Result: 3× qualified monthly leads, CPL down 48%, close rate up 22% thanks to pre-call nurturing.
A SaaS startup with a strong product and a serious problem: CAC too high relative to LTV, with an LTV:CAC ratio of 1.8 (the industry target is 3×+). We automated the onboarding funnel with behavioural sequences, integrated CRM and product data to flag early churn signals, and optimised performance campaigns with predictive LTV-based bidding. In 8 months: CAC -40%, activation +31%, monthly churn -18%.
A furniture e-commerce store with a slow site (Core Web Vitals in the red), zero SEO strategy and total reliance on paid advertising for traffic. We ran a full technical migration to an optimised semantic structure, brought mobile LCP under 2 seconds, and produced 40 pillar articles over 6 months with a topic-cluster strategy. Organic revenue: from €0 to €18K/month.
A manufacturing company with 40 hours a week of repeatable manual work: quotes built by hand, order updates by email, semi-manual invoicing and unsystematic post-sale communication. We automated the entire flow — from quote to invoice — with CRM-ERP integration and automated post-sale communication with dynamic personalisation. ROI on the investment: 9 months.
A food brand with tight margins (35%) and a limited ad budget. The goal was to prove TikTok could be profitable on under £2K/month — what bigger agencies call impossible. Native content produced in-house with our strategic briefs, UGC ads with micro/nano creators, weekly optimisation on real ROAS (not platform-reported). Average ROAS achieved: 5.2×. Break-even was 2.86×.
In 9 months we more than tripled our online revenue. Every week the data spoke for itself. A serious team, direct communication, zero fluff. It's the first agency I've worked with that explained the why behind every decision — not just the what.
I worked with three agencies before Nexagen. The difference is they treat your numbers as if they were their own. They build systems that actually work — not presentations that look like they work.
The AI automation completely changed how we operate. 24 hours a week saved means my sales team can focus purely on closing, not paperwork. We saw the ROI within the first quarter.
