Modernizing Campaign Management with a Scalable, Multi-Brand SaaS Platform

When most companies think about modernizing, they picture a visual upgrade — maybe a cleaner UI, a smoother dashboard, or faster load times.

But true modernization goes deeper.

It’s about building a system that evolves with your business, supports scale, adapts to real-world workflows, and can embed intelligence at the core. This is what we call AI-ready architecture — and it’s what most teams miss.

The transformation we delivered for Nexta, a fast-growing SaaS advertising platform from Denmark, is a perfect example of what smart modernization actually looks like in practice.

When Nexta approached us, they had a vision:
Replace a bloated, fragmented legacy system with something modern, modular, and built for scale — without losing the campaign logic and user familiarity they’d built over time.

But they weren’t looking for a flashy rebuild.
They needed a business-ready platform in under 3 months. That meant balancing:

• Complex workflows across 100+ active accounts
• Multi-role permissions and brand-specific customizations
• Real-time media planning, analytics, and creative approvals

And doing it all without breaking what already worked.

At Jazzy, we approached the challenge in phases — designed not just to replace, but to rethink how the platform could operate smarter in the long run.

• Workshops & Discovery

  We started with deep-dive UX workshops to uncover friction points in the legacy system. We mapped workflows across marketing teams, designers, and admins to define real business goals.

• Information Architecture & Wireframes

  Over 100 wireframes were created to align views with user roles, streamline navigation, and reduce unnecessary steps — making space for intelligent triggers in future iterations.

• Modular, SSR-Ready Frontend

  We delivered a fully server-side rendered app (React + Next.js), designed for speed, security, and SEO. The frontend was flexible enough to support future AI-layer components without a full rewrite.

• Campaign Manager & Preview System

  We built a realistic ad preview module — a crucial feature that reduced errors and feedback cycles. Teams could now see what would go live, in context, across different brands and campaigns.

• Role-Based Admin Panel with GDPR Controls

  Multi-level access was implemented for editors, admins, clients, and reviewers — ensuring control and compliance across accounts.

The results? Immediate and long-term.

• Faster campaign cycles

  Thanks to the new UX and collaborative workflows, creative approvals and onboarding time dropped significantly.

• Increased platform adoption

  A more intuitive UI led to a measurable uptick in user activity — with praise from internal teams and clients alike.

• Scalable foundation for growth

  The architecture now supports new features, brands, and markets — without expensive rework.

• Higher client satisfaction

  Better previews, fewer errors, faster approvals — all leading to improved outcomes for publishers and marketers.
