At Synexus, we're helping advertisers rethink how they show up in the news ecosystem. After a successful investment round, we are now in the process of launching a new brand and product to the Ad tech market.

Today, blunt keyword blocking causes brands to avoid entire news sites — even when the content is high-quality, balanced, and aligned with their values. It’s like tossing out a whole basket of fruit just because one apple has a bruise.

Our technology changes that. Instead of just scanning keywords, Synexus analyzes how topics are being discussed. This allows advertisers to safely reintroduce premium journalism into their media plans — driving better reach, performance, and efficiency without added risk.

At Synexus, you’ll be surrounded by people who want to improve everything and support everyone around them. Our team is passionate about our mission, are experts in their fields and are collaborative problem solvers.

We model the following behaviors across the organisation:

Positivity - We approach challenges with optimism, realism, and a focus on progress.

Respect - We create an environment where everyone feels heard, valued, and safe to contribute.

Accountability - We take responsibility, keep our commitments, and support each other in delivering results.

Outcomes Focus - We prioritise impact over process, keeping customers, employees, and shareholders at the heart of what we do.
