Co-founder Insights

Transitioning from a mere idea to a functioning SaaS company is often described as building a plane while it’s already in the air. For me, the first twelve months of that journey have been a masterclass in focus, courage, and prioritisation.
Reflecting on a year of rapid growth, here are three pivotal lessons that every early-stage founder should internalise to avoid common pitfalls and accelerate their path to product-market fit. Here is a deeper look at the insights that shaped ProfitPeak’s first year.
Lesson 1, The Quality Trap: Why More Beta Users Isn’t Always Better
In the early days of a startup, it is tempting to equate a high volume of sign-ups with success. However,I believe that product-market fit (PMF) isn't a numbers game; it’s a resonance game. Product-market fit doesn’t come from signing up as many beta users as possible, it comes from working with the right ones.
When you fill your beta programme with users who lack the resources or the genuine motivation to solve the problem your product addresses, you create "feedback drag." These users drain your support time and provide shallow data that can lead your roadmap astray.
Instead, your sales pitch should serve as a filter. By validating that a lead fits your Ideal Customer Profile (ICP) before onboarding them, you ensure that every hour spent on feedback is an hour spent building towards a scalable solution.
Lesson 2, Don’t Fear the "Big Fish"
Many founders suffer from "readiness anxiety"—the belief that their product needs to be polished and perfect before they approach established, sophisticated brands. There is a persistent fear that if you pitch a large client too early and fail, you’ve burnt that bridge forever.
My experience suggests the opposite is true. For us, approaching larger retail customers early in the journey can actually be the catalyst that forces your product to mature. These "sophisticated" users often have the most structured feedback and the most defined needs.
The key is two-way validation. When you find a large partner who has the internal resources to actually use your product and share honest critiques, a unique synergy forms. Their investment in your success creates a shared urgency, pushing your product further and faster than a hundred "casual" users ever could.

Lesson 3, The Framework of Focus: V.E.I.
As a founder, your most scarce resource isn't money—it’s development time. In our profit intelligence platform, every feature request feels urgent, but trying to please everyone is a one-way ticket to a bloated, confusing product.
To combat this, I recommends a simple but rigorous lens for every decision: Validation, Effort, and Impact.
Validation: Does this align with our long-term roadmap? How many customers are actually asking for this?
Effort: What is the "cost of build"? Is this a quick UI tweak or a three-month structural overhaul?
Impact: How much value will this actually deliver to the user’s bottom line?
By filtering every request through this framework, you move away from "reactive building" and towards strategic growth. It allows you to say "no" with confidence so that you can say "yes" to the features that truly move the needle.
The Founder’s North Star: Mindset
Beyond the frameworks and the ICPs, I emphasise that the ultimate driver of success is the collective mindset of the team. Building a SaaS is a marathon of "small wins" that compound over time. Every minor UI improvement and every lesson learnt from a mistake adds up.
Perhaps most importantly, a growth mindset acts as an emotional buffer. There will be "shit days"—that is a guarantee. But by viewing every challenge as a data point for improvement, you keep the momentum moving forward.
