About David & Goliath
How we work
David & Goliath is an Australian AI consulting firm that builds intelligent operating systems for lean teams with 10 to 500 employees. Rather than offering isolated tools or channel-specific services, the firm deploys three interconnected systems: the AI Growth Engine for automated revenue infrastructure including pipeline generation and outbound systems, Employee Amplification Systems for augmenting team output and reducing reliance on headcount growth, and the Secure AI Brain for protected organisational intelligence with secure, scalable AI deployment. Every engagement follows an embedded operating partner model on a fixed monthly retainer, with first systems typically live in 4 to 8 weeks.
About Megaphone Marketing
How Megaphone works
Megaphone Marketing is one of Australia's largest performance marketing agencies, founded in 2013 and now employing over 120 specialists across Melbourne, Sydney, and Brisbane. In 2024, Megaphone was acquired by Pixis, a $214 million funded AI-native advertising platform with over 200 proprietary AI models. This gives Megaphone access to advanced campaign optimisation, audience targeting, and creative generation capabilities. Their client base is predominantly B2C ecommerce, with an impressive roster including lululemon, F45, and Puma. They report a 9x average ROAS and 96% client retention. The Pixis acquisition positions Megaphone as an AI-enhanced agency, though the AI is used to improve campaign performance internally rather than offered as a standalone service to clients.
Core Differences
What sets us apart
Acquired AI vs Built-in AI
Megaphone gained AI capability through the Pixis acquisition in 2024. David & Goliath builds AI systems from the ground up for each client's specific context. The distinction matters: acquired AI enhances existing workflows, while purpose-built AI can reshape them entirely.
Channel Optimisation vs Organisational Transformation
Megaphone uses AI to make advertising campaigns perform better. David & Goliath uses AI to make entire businesses operate differently. One optimises spend, the other restructures how revenue is generated, knowledge is managed, and decisions are made.
AI as Internal Tool vs AI as Client Asset
Pixis AI powers Megaphone's campaign management behind the scenes. Clients benefit from improved results but do not own or access the technology. David & Goliath builds systems that clients own, operate, and compound value from over time.
Scale through Headcount vs Scale through Systems
Megaphone scales by growing their 120+ person team. David & Goliath scales by building systems that multiply the output of your existing team. One adds external capacity, the other amplifies internal capability through Employee Amplification Systems.
Key Questions
Common questions answered
Does Megaphone offer AI consulting or AI strategy services?
No. Megaphone uses AI internally through the Pixis platform to improve campaign performance, but they do not offer AI consulting, AI strategy, or AI implementation as a service. If you need AI systems built into your business operations, that falls outside their scope.
How does the Pixis acquisition change what Megaphone offers?
The Pixis acquisition gives Megaphone access to over 200 proprietary AI models for campaign optimisation, audience targeting, bid management, and creative generation. This makes their advertising execution more sophisticated, but the service offering remains performance marketing. Clients benefit from better results, not from AI capabilities they can use elsewhere in their business.
Can David & Goliath manage our ad campaigns like Megaphone does?
David & Goliath does not manage paid media campaigns. If you need hands-on PPC, paid social, or programmatic management, Megaphone or a similar performance agency is the right fit. David & Goliath builds the AI infrastructure that sits around and above your marketing, connecting revenue systems, automating workflows, and making your team more effective across the entire business.
Could we use both Megaphone and David & Goliath?
Yes, and this combination can be powerful. Megaphone handles performance marketing execution with AI-enhanced campaign management, while David & Goliath builds AI systems across the rest of your operations. The AI Growth Engine can integrate with your marketing data to create a unified revenue intelligence layer.
When to Choose Megaphone
Where Megaphone may be the better fit

When to Choose David & Goliath
Where David & Goliath may be the better fit
- ✓Lean teams that need AI woven into their daily operations, not just their ad campaigns
- ✓Businesses where the bottleneck is operational: manual processes, siloed knowledge, disconnected systems
- ✓Organisations that want to own their AI systems and compound intelligence over time
- ✓Companies seeking a strategic AI partner embedded in their business, not a channel execution agency
- ✓B2B or B2C businesses ready for organisation-wide transformation, not just campaign-level improvement
Industry Landscape
Understanding the AI consulting landscape
The Australian marketing agency landscape is shifting as AI capabilities become a competitive differentiator. Megaphone's acquisition by Pixis represents one path: bolting advanced AI onto an established agency model to enhance campaign performance. David & Goliath represents another: building AI-native operating systems that change how businesses function. Both are legitimate approaches to different problems.
Market Context
Where this comparison fits in the market
Performance marketing agencies are increasingly integrating AI into their campaign management workflows, driven by platform complexity and the volume of data required for effective optimisation. The Pixis acquisition of Megaphone signals that AI-powered campaign intelligence is becoming table stakes for top-tier agencies. However, this trend addresses only one slice of business operations. For organisations where growth is constrained by internal processes, knowledge management, or team capacity rather than ad performance alone, AI consulting firms address a fundamentally different layer.
