The classic tension between Sales and Marketing teams makes each view the other as putting the cart before the horse that’s them. But if all you have is a hammer, which is all that a startup does, just nail a horseshoe and ride the horse yourself.
At early stages, you don’t have the luxury of large budgets, siloed teams, or seasoned experts specialising in narrow roles. This is the reality for early-stage B2B startups. Messy, unorganised and far more interesting. You don’t have the luxury to choose one over the other. Instead, you need a composite machine which brings them together. A lean, high-performance engine that generates revenue, informs product development and delights early customers.
This is where the lines blur—between sales, marketing, customer success, and even product—and where founders need to think differently.
The Unified Revenue Engine
In any startup, Sales, Marketing and Customer Success begin as an integrated function with two simple goals. Revenue and Product Market Fit.
Clubbing these functions together isn’t purely driven by resource constraint, but by a natural relationship they enjoy because of an overlap between their tasks and outcomes, and the way each feeds into the other.
Product teams, while often treated as separate, are deeply intertwined. In fact, your early sales and marketing activity is your product research. Every conversation with a customer should influence the roadmap.
Let’s take a quick look at the traditional roles of Sales and Marketing and where they now overlap in a startup context:
Sales vs. Marketing in Startups: A Quick Comparison
| Function | Marketing | Sales | Overlap |
| Outreach | Campaigns (email, social, ads) to drive top-of-funnel awareness | Direct emails, cold calls, prospecting | Messaging, audience targeting |
| Leads | Attracts leads through content, SEO, webinars, etc. | Converts leads into opportunities and customers | Qualification criteria, ICP discovery |
| Frontline | Engages prospects through content, brand presence | Engages prospects through 1:1 conversations | Customer engagement |
| Narrative | Develops brand, voice, positioning | Tailors pitch and objection handling based on real-time feedback | Messaging alignment |
| Revenue | Indirect driver: creates demand | Direct driver: closes deals | Attribution and performance tracking |
| Budget | Spends on tools, campaigns, and creatives | Spends on reps, CRM, commissions | ROI analysis |
| Feedback Loop | Captures top-funnel feedback on content and channels | Captures mid-to-bottom funnel feedback on objections, pricing, etc. | Insight to product and positioning |
| Human Touch | Scaled via content and automation | High-touch human interaction | Personalization at different stages |
Building a Lean Revenue Engine
Instead of obsessing over where sales ends and marketing begins, focus on building a single, agile system that loops together learning, revenue, and product validation.
Here’s how:
1. Evaluate Your Goals
Start by defining what success means right now. Is it validating your ICP? Booking 10 discovery calls a week? Converting your first 10 paying customers? Avoid vanity metrics—focus on learnings and traction.
2. Build Processes Around Those Goals
Design simple, repeatable workflows: outreach cadences, demo scripts, onboarding templates. Don’t over-engineer. You’re aiming for speed, not scale—yet.
3. Run Small Experiments
Test different value propositions, channels (LinkedIn, cold email, webinars), pricing models, or onboarding flows. Keep each experiment focused, and short in duration.
4. Evaluate Success and Enable Automation
Did the cold outreach campaign convert? Did your webinar generate leads? Automate what works—email sequences, follow-ups, qualification criteria—so you can double down.
5. Develop Process Around Success
Once something works, build a lightweight process or playbook around it. This is the start of your scalable GTM motion.
Early Revenue Experiments: What to Focus On
Your first sales and marketing efforts should focus on three core outcomes:
- ICP (Ideal Customer Profile): Who is your buyer? What are their pain points, job titles, and industries? How do they describe their challenges?
- Product Feedback: What features matter most? Where does the pricing feel off? What objections keep coming up?
- Sales Cycle Mechanics: What’s working in outreach? What messaging resonates? How long does it take to go from conversation to conversion?
Treat each of these as a mini-research project. Every response, rejection, or closed deal is data.
Make Feedback Loops Your Superpower
What binds Sales, Marketing, CS, and Product together isn’t headcount—it’s feedback. Every customer touchpoint is an opportunity to learn:
- Marketing sees what brings attention
- Sales hears what makes people buy (or not)
- CS hears what makes customers stay (or churn)
- Product builds what solves the actual problem
The real power is when these learnings are shared across the team in real time. That’s your startup’s competitive advantage.
Final Thoughts: Embrace the Blur
As a founder, your job isn’t to draw hard lines between departments. Your job is to build the revenue engine that informs product, builds brand, and closes deals. This engine thrives on overlap, feedback, and iteration.
So embrace the blur. That’s where your growth lies.
