In this episode of Beyond One Million, Parna Sarkar-Basu speaks with John Harthorne, founder and managing director of Two Lanterns Venture Capital and founder of MassChallenge on what investors really look for, why resilience matters and how founders can scale beyond $1 million.
“Reaching $1 million in revenue is a milestone. Staying on a growth path after that is the harder test.”
Harthorne has seen startup growth as a founder who helped build one of the most recognized startup accelerators and as an investor evaluating early-stage companies. His advice to founders is direct: the product matters, but the team, the market and the ability to keep learning matter more.
For founders trying to move from $1 million to $5 million, that distinction can determine whether early traction becomes scalable growth.
Key Takeaways
Entrepreneurship Starts with the Need to Build: Harthorne’s path to entrepreneurship was not a straight line. He had side gigs in high school, resisted traditional career paths and felt drawn to creating things on his own. A conventional career track felt too narrow. Entrepreneurship offered something different: autonomy, learning, community and the ability to solve meaningful problems. That desire to build became the throughline. For Harthorne, startups are powerful because they give people a way to turn ideas into impact. The best founders are not simply chasing a company. They are trying to solve something that matters.
Impact Has to Become a Business Model: Harthorne makes a clear distinction between solving an important problem and building a business that can sustain itself. A founder may have a mission that matters, but that mission still has to translate into value creation, revenue and execution. A company has to solve a real problem for a real customer. Then it has to capture enough value to keep growing. That is where many founders, especially mission-driven founders, can get stuck. Good intentions may inspire people, but they do not automatically create customer demand.
“Tech for good” still has to be good business. Purpose creates the reason to exist. The business model creates the ability to scale.
Investors Bet on the Team First: At the early stage, Harthorne says investors are not primarily betting on the product. They are betting on the founders. For pre-seed and seed-stage companies, he described the investor lens this way:
- 70% team
- 20% market
- 10% product and traction
The logic is simple. Early products change. Business models evolve. Startups pivot. The first version of the company is rarely the final version. That makes the founding team the most important variable. Investors want to know whether the team can learn, adapt, sell, build and stay focused when the original plan changes. The product still matters, but mainly because it shows whether the team can execute. Has the team identified a customer? Built something useful? Found a market with enough room to grow? Taken action instead of staying theoretical?
“A pitch should not be only a product demo. It should show why the team is capable of navigating uncertainty and building a company that can evolve.”
Resilience Is More Than Grit: Harthorne places heavy emphasis on resilience because startup life brings repeated failure. Founders may lose more days than they win in the first several years. They still have to get up, return to the market and keep trying. But resilience is not the same as pretending everything is fine. He also looks for honesty. Founders who tell investors, advisors and stakeholders that everything is working perfectly make it harder for anyone to help. Strong founders can say what they know, what they do not know and where they need support. That candor becomes a leadership signal.
“Resilience is not blind optimism. It is the ability to keep moving while being honest about what is broken.”
What Gets You to $1 Million May Not Get You to $5 Million: The skills that help a founder get from zero to one are not always the skills that help the company grow from one to ten. In the early days, the founder can carry the company. Sales may come from personal relationships. Culture is informal. The team is small. Everyone is close to the mission. Growth changes the job.
As the company scales, founders have to hire people they may not know personally. Sales can no longer depend on one person’s network. The company needs systems, managers, processes, customer infrastructure and a way to translate the founder’s vision through other people. The original challenges do not disappear. New ones get added.
Fundraising, team management and vision still matter. But now founders may also face larger customers, stronger competitors, media scrutiny, operational costs and internal complexity.
“The company does not get easier after early traction. It gets more complex. Founders have to keep learning as the business changes around them.”
Customer Understanding Is the Real Growth Engine: Founders need to understand customers better than customers understand themselves. That means going beyond surface-level pain points and learning how customers make decisions. What are their budgets? What are their success metrics? What are their fears? What internal pressures shape the buying decision? Which customers are worth growing with?
Which customers will cost more than they create?
Harthorne’s advice is: early customer conversations should be 80% listening and 20% talking. Customers do not buy elegance. They buy a solution to a problem.
“The best founders do not just explain the product better. They understand the customer better.”
AI Startups Need More Than an AI Label: Harthorne also addressed one of the biggest questions in today’s startup market: what actually counts as AI value? As an investor in AI startups, he sees many companies pitch themselves as AI companies when they are primarily using existing models through a user interface. In some cases, they are what he called AI wrappers: companies calling tools like Gemini, OpenAI or Claude to do the core work without building differentiated AI capabilities of their own.
The opportunity is still significant, but the bar is higher. Enterprise customers are not ready to hand over full control of their business processes to autonomous systems. The near-term opportunity is more practical: AI that improves workflows, supports decisions, keeps humans in the loop and removes low-value work. The strongest AI companies are not just selling the category. They are selling a business outcome customers are ready to buy today.
“AI is not a positioning shortcut. Founders need to show where the company creates differentiated value and how that value improves the customer’s business.”
The Bottom Line
For founders trying to scale beyond $1 million, Harthorne’s message is clear: early traction is not enough. The next stage requires a stronger team, a sharper understanding of the customer, a market with room to grow and the resilience to keep learning when the business becomes harder to manage. The companies that scale are not always the ones with the most elegant products or the flashiest pitch decks. They are the companies that keep adapting, keep listening and keep building the operating muscle needed for the next stage of growth.
The first million proves the company has a chance. What happens next proves whether it can scale.
