Introduction

Do you need deep industry experience to build a billion-dollar B2B company? The answer is mixed - both insiders and outsiders can win.

What’s the problem it solves?

People often wonder if only domain experts can build huge B2B companies, or if newcomers with fresh ideas can succeed too. This article looks at real examples to show that both paths can work.

Quick Summary

Some of the most successful founders were seasoned experts. They had decades of industry knowledge before starting their companies, which gave them confidence and insight into real problems. Examples include Eric Yuan at Zoom, who knew video conferencing inside out, and Peter Gassner at Veeva, who spent decades in enterprise software.

Others succeeded with little or no industry background. Instead, they spotted problems as outsiders or built tools for themselves that later became massive businesses. Stewart Butterfield built Slack from a failed game project, and Tobias Lütke turned his personal need for a snowboard store into Shopify. Their advantage was fresh thinking and solving problems that insiders often overlooked.

There’s also a middle group - founders who had some technical or adjacent experience but weren’t full domain experts. HubSpot’s Dharmesh Shah and Brian Halligan, for instance, weren’t marketing veterans but saw that old tactics were failing and introduced “inbound marketing.”

In the end, both approaches can work. Success doesn’t depend only on background but on persistence, hiring strong teams, staying efficient with money, and focusing on real customer problems.

Key Takeaways

• Domain expertise gives focus and credibility but can also create blind spots.
• Outsiders bring fresh thinking and can spot overlooked opportunities.
• Persistence, efficient use of money, and strong hiring matter more than background.
• Customer obsession is the ultimate equalizer - listening to them drives the right product decisions.
• Both insiders and outsiders who succeed keep iterating until people love their product.

What to do

• Don’t overthink your background - focus on solving real customer problems.
• If you’re a domain expert, balance your deep knowledge with outside perspectives.
• If you’re an outsider, lean heavily on customer feedback and hire domain specialists.
• Protect your runway - stay efficient with money while you search for product-market fit.
• Build word-of-mouth by making something people truly want to share.
