The moment we started treating customers as collaborators instead of just end users, everything got sharper — messaging, product, direction.
When you start a company, everyone talks about the wins. But the real breakthroughs come from the mistakes you make along the way. Here are five lessons I learned the hard way, but wouldn’t change for anything: 1) Start before you’re ready. If you wait for the perfect moment, you’re already too late. The only way to figure out what works is by launching, learning, and iterating in real time. 2) Sell before the product is “done.” Your product will never be truly "ready." The best way to build something people actually want is to put it in their hands early and shape it with their feedback. 3) Your customers aren’t just clients, they’re partners. The best insights don’t come from internal brainstorms. They come from sitting down with customers, understanding their pain points, and building with them. Because if you're not in constant conversation with them, you're missing out on your biggest growth lever. 4) Not being the top user of your product. If you wouldn’t use your own product daily, why should anyone else? The best salespeople are the ones who believe in and live the product themselves. 5) Not thinking like a founder. Founders don’t wait for permission. They sell vision before a product exists, turn feedback into features, and thrive in ambiguity. Everyone at an early-stage startup needs to think this way. These lessons shaped Kalder from day one. If you’re building, scaling, or just figuring things out, lean into the mistakes. They might just be your biggest advantage. What’s a risk you took that paid off?
