7 Go-to-Market Lessons from Lightyear’s Path to Enterprise Success

Scaling a B2B company requires more than just a good product – it demands ruthless focus and constant evolution of your go-to-market strategy. In a recent Category Visionaries episode, Lightyear CEO Dennis Thankachan shared hard-won insights from growing his company 30x in just two and a half years. Here are the key lessons that emerged from their journey:

1. Don’t Let Early Success with SMBs Cloud Your Judgment

Sometimes your initial market choice can be wrong, even if you’re seeing some traction. Dennis learned this the hard way: “Initially went after SMB, and I actually think that was a bad decision in retrospect.” The reason? Market dynamics they hadn’t fully appreciated: “Enterprises spend way more money on telecom and they also have way more people allocated to the problem. As a result, a product can drive more surface area of value within an enterprise.”

2. Build Your Marketing Engine Around Purchase Intent

Lightyear’s early success came from a laser focus on high-intent keywords. Dennis explains: “We identified long tail keywords within Google search that correlate to purchasing intent with a high degree of specificity… Not a ton of traffic on that keyword, but it’s likely that a large percentage of the traffic around that keyword is a person that is a buyer.”

3. Recognize the Limits of Your Current GTM Motion

Even successful strategies hit scaling limits. While Lightyear still benefits from their inbound engine, Dennis acknowledges its constraints: “We still have a wonderful inbound funnel, but there are caps on how far that’ll scale.” This realization led them to build “something that looks more like the way that a ServiceNow would go to market.”

4. Embrace the Art-to-Science Evolution

Enterprise GTM typically evolves through two phases. Dennis describes the first as “this art period of really determining what the buyer wants, how to price, how to message it, who I should go after.” Only after this experimentation can you “put business model and unit economics around that” and transition to a more systematic approach.

5. Let Constraints Drive Better Decision-Making

Counter-intuitively, having too much capital can hurt growth. Dennis notes they’re “growing faster at bigger numbers with the constraints in place, because we’re operating as if that next dollar is not necessarily guaranteed.” This mindset forces better decisions and more efficient operations.

6. Resist the Temptation to Expand Too Broadly

Despite pressure to diversify, maintaining focus is crucial. As Dennis puts it: “The market is so large, there can feel pressure to like, oh, focus on something outside of telecom, do this, that and the other. I’m very much focused on depth over breadth.”

7. Build Systems That Scale Beyond Founder Involvement

True enterprise success requires moving beyond founder-led sales. Dennis emphasizes the importance of “building a system that’s unit economic, profitable from a quota perspective. You need to think about if you’re going to have a rep, how are you going to keep that rep fed with leads… in a way that generates more money than you spend on the team.”

The results speak for themselves: Lightyear now has 275+ customers managing “deep into the tens of millions of dollars of telecom spend.” Their evolution from SMB-focused startup to enterprise software company offers a blueprint for founders navigating similar transitions.

But perhaps the most important lesson is the value of being willing to change course when data suggests your initial strategy isn’t optimal. As Dennis’s experience shows, sometimes the fastest path to growth requires admitting your first approach was wrong and rebuilding your GTM from the ground up.

This systematic approach to finding and scaling what works, rather than sticking to initial assumptions, has enabled Lightyear to build a repeatable enterprise sales motion that continues to accelerate their growth. For B2B founders, it’s a powerful reminder that success often comes not from following conventional wisdom, but from being willing to learn and adapt based on market realities.
