The CMO investment challenge
Changing marketing priorities from seed to D
There is no one right way to do b2b or b2c tech marketing for start-ups. It depends on your business model, your go-to-market strategy, your route to market and your company’s maturity. Funding round is useful shorthand, but it is not an absolute measure of marketing sophistication. It is simply a broad framing for how much change, structure and marketing architecture a company will often need to build over time.
What usually governs the real shape of the challenge is more specific than funding stage alone:
- ICP clarity and buyer complexity
- ACV and sales motion
- Founder profile and internal capability
- Product complexity and category maturity
- Route to market, including direct, partner and channel-led growth
- Geographic ambition and pace of scale
That is why two businesses at the same funding stage can need very different marketing answers. One may need stronger brand and proposition work. Another may need sharper product marketing, better conversion journeys and sales enablement. A third may need more consistent communications to support investor confidence and market trust.
In the earliest phase, what matters is usually not volume. It is sharpness. You need a flexible, lightweight brand, product and communications framework built around the founders’ vision, with enough clarity to win belief from customers, partners and investors. As the company moves through seed, series A, B and beyond, that framework needs to harden. Not all at once. Not in some bloated corporate form. Just enough to help the business look more credible, move more consistently and convert attention into momentum.
That creates a familiar tension:
- Do too little and you struggle to convince the market
- Do too much too soon and you create a straitjacket for a business that is still learning what it is
- Build the right next layer and you improve credibility, consistency and commercial traction
That is why the job is not to build everything. It is to build the right next layer. For some brands that means tightening brand strategy and proposition. For others it means improving digital journeys through Web + UX development, or raising the sales conversation with The Message Elevator and sales enablement. The path changes. The need for conscious sequencing does not.
The Rubicon Agency works closely with start-ups to develop the optimal brand, marketing and communications strategy for the maturity they are in, and the maturity they want to reach. Our specialist technology marketing expertise is there for ambitious start-ups at every stage of the funding journey.
As a CMO, you face 3 marketing vectors
All need to be underpinned by a mesh of technologies and platforms for control, optimisation and scale. But before that comes something simpler. Clarity.
Brand & product marketing
Create a visual and verbal expression that is right for your business and audience, but flexible enough to let you evolve and grow. That includes the brand system, the proposition, the positioning and the product story. In tech, those things rarely sit far apart. Product marketing is often the mechanism that turns brand intent into commercial relevance, especially when the proposition is complex or the buying group is broad. The Rubicon Agency’s product marketing offer reflects that reality.
Revenue marketing
Give your sales and channel teams the tools, programmes and campaigns they need to hit the targets for the next stage. That might mean lightweight founder-led motion. It might mean digital lead generation, enterprise demand generation, focused account based marketing or partner marketing. It may also mean stronger acquisition journeys, tighter conversion paths, better nurture flows, sharper campaign optimisation and more effective retention support. The important thing is not whether a motion looks early-stage or late-stage on paper. It is whether it matches the economics and route to market of the business.
Marketing communications
Use targeted communications to elevate and amplify your message so it lands with potential customers, partners, influencers and investors. Founder voice usually matters most at the beginning. Over time, the job expands into a more deliberate mix of thought leadership, strategic content and corporate comms. That needs judgement and balance. Stakeholders want substance, not noise. This is where brand awareness, trust and transparency play a bigger role in decision-making – especially in an environment where marketing budgets are reported as flat, and in some cases declining.
The marketing investment maturity path
At all stages of the start-up funding journey, the marketing agendas within each vector will differ as goals become bigger, braver and more commercially demanding. But the path is not fixed. It is not universal. And it is not governed by funding round alone.
Still, broad patterns do exist. Most brands do build layers over time. In most cases, you will see movement like this:
- Brand becomes more deliberate and more consistent
- Product story becomes clearer and more commercially useful
- Demand generation becomes more intentional and better targeted
- Sales enablement becomes more structured
- Communications become more proactive and more confident
- The operating model behind all of it becomes more joined-up
That broad arc is what this piece is trying to capture.
The CMO investment challenge is to recognise the pivots required in the run-up to each raise, then to convince investors and leadership on the genuine must-haves for the next stage. In practical terms, that usually means deciding:
- what must be built now
- what should be strengthened next
- what can stay light for longer
- what would be overkill at the current stage
The backdrop makes those calls harder. 6sense’s Buyer Experience Report shows buyers are doing more of their research independently, SaaS Capital’s 2025 spending benchmarks put median private B2B SaaS marketing spend at 8% of ARR, and WARC’s brand-to-demand work argues that sustainable growth comes from connecting brand and demand rather than treating them as separate worlds.
We call this the marketing investment maturity path because it helps leaders frame what often changes as a company grows. Not because every series‑A brand should look the same. Or every series‑C business should buy the same stack, hire the same roles and run the same programmes.
