Part 3: How to Make Your Techstars Application Stand Out

After hundreds of investments, thousands of mentor sessions, and a few hard-won pivots, three Techstars investors sat down to share what consistently separates founders who break out from those who stall.

In our Inside a Techstars Accelerator session, Top 10 Learnings From Working with Techstars Founders, Nick Culbertson (Managing Director, Techstars AI Health Baltimore), Vance Dekker Vargas (Investment Manager, Techstars Anywhere), and Arthur Parens (Investment Analyst, Techstars Future of Food powered by Ecolab) counted down the patterns they see most often.

10. Be Obsessed With the Problem, Not the Solution

Nick set the tone with a familiar founder pitfall. "Founders are frequently really excited about their baby, what they've built. They want to tell you about what they built when you come in and meet a founder for the first time."

His challenge: flip the focus. "Focus on the problem and make sure that you have a real, full understanding of the problem."

Why? Because solutions are often shaped by personal preferences and biases that drift away from real customer needs. "Sometimes the solution that you have built is something that you believe in because of your own personal preference or biases."

Arthur shared a saying his team uses to push founders toward this mindset. "If you're not embarrassed by your first product you put in front of a customer, you've overbuilt."

Vance framed the difference clearly. "The founders that are closest to the market that they're actually addressing are obsessed with the problems of their potential users, rather than kind of what they can do or what they already know how to execute."

9. Be Coachable Without Being a Pushover

The line between confidence and stubbornness gets blurry fast. Arthur described the balance: "Make sure that you have enough conviction in your idea that it can stay the course... but at the same time, being able to take feedback, pattern match, understand."

Vance went further. "A lot of our best founders are stubborn... we want you to be open to hearing new perspectives on your space and what you're building. But at the end of the day, you need to have confidence in what your vision is."

Coachability, he said, is about listening, not about doing whatever you hear. "We're looking for, when we talk about coachability, is really that you're listening and you're paying attention to the feedback you're getting... not necessarily that you're actually executing everything you hear, which is also impossible because you hear so many different things."

Nick illustrated the cost of getting stuck on the wrong thing. One of his portfolio companies had spent eight months on a clinical trial and won a major EHR integration, only to have a massive incumbent announce they were building the same feature. The founders pivoted. "They were not stubborn on the wrong things."

8. High EQ Is Not Optional

Vance said high emotional intelligence shows up everywhere in great founders. "This is something we're always looking for in founders, that they can successfully navigate their own emotions and the emotions of their team. They can manage their egos."

It also matters externally. "You can't get a startup off the ground alone."

Arthur added that this is exactly why team weighs so heavily in the Techstars decision process. "Techstars, we focus on six key things, three of which are all the same: team, team, team."

7. Know Your Real Levers, and Beware Vanity Metrics

Nick called this one obvious in theory and brutal in practice. "Chasing after vanity metrics can actually direct you in the really wrong direction, where you think that you're making progress, but actually you're spinning your wheels because the wrong KPI has been selected."

His simplest test: when in doubt, fall back to two universal metrics. "There's only two metrics that apply to 100% of companies. And one is, how much revenue do you have... And the second is how frequently you're talking to customers."

He also warned about a habit he sees constantly: metric hopping. "I'll check in with founders on a regular basis and they'll say, last month we had 70% increase in monthly active users... And the next month I check in and they say, activation time is down by 15%." The result? "There's no direction in the company. They're fading back and forth."

Another silent vanity metric is fundraising itself. "How much money have you raised or how big your valuation is... that's not an indication that you are solving a problem. That's an indication that you can fundraise really well."

Vance closed the section with a sharp distinction. Internal product KPIs are easy. The real ones are not. "You can build a great product in a vacuum. But unless you really know what tracks for growth, it's not going to be a great startup. It's just going to be kind of a cool technical project."

6. Ruthless Prioritization

Arthur kept this short and tied it back to KPIs. The job is "understanding and not getting distracted by the numerous other ways of potentially getting to a goal." With clear KPIs and OKRs, prioritization becomes a discipline rather than a guessing game.

5. Who, Not How

Vance described one of the hardest skills for founders: knowing when to delegate. "The ability to handle 'how' so that you can focus on the bigger picture as the CEO."

The math is unforgiving. "If you need to micromanage everything, you're just never going to be able to actually build a team and add net value every time you bring on someone new."

4. Practice the Basics, Forever

Nick used willingness to pay as his case study, calling it his favorite three-letter acronym. "Willingness to pay is the first thing you need to prove to get your commercial traction going to market. But it's not the last."

At his previous company, his team built a process around revisiting it. After every closed deal, someone other than the seller would ask the customer why they bought. That insight then drove success metrics tracked over the contract's life. "When we came up for renewal two and a half years later... we would come back and say, remember, you bought us for this reason, and we tracked the success metric, and here's all the success you have... and here's why we're raising your price."

The result: "Net negative revenue churn, which is exactly the goal."

Arthur jumped in with what he called the most important bullet on the slide: communication. Specifically, investor and team updates. "You'd be shocked by how many founders fall off and stop sending company or investor updates on a monthly or quarterly basis. This is the biggest leverage point that you have."

His message to founders who only reach out when things are going wrong: "We can't help you if we don't know what's going on... It doesn't always need to be good updates. Can be bad and lowlights. But if we don't know what's going on, we can't help. And sometimes it's too late."

3. Volume Is Your Friend

Whether it is customers or investors, Arthur said, the math just is what it is. "The likelihood of you having success after 10 conversations is extremely low."

His fundraising rule of thumb: "Expect 99 declines. But in order to fill a round, you're really only going to need three to four investors. So volume is your friend here."

Vance added a process layer: treat your customer discovery as a series of experiments, not opinions. "Having a clear idea of the assumptions you're going in with about your product, and treating those as hypotheses... that's something you actually need to track once you ship the feature."

He warned against leading the witness during discovery. "You're assuming that they understand that problem. You're assuming that they're willing to pay for that problem. Those are all hypotheses... that you need to validate, without serving your answer to the customer. Without telling them, well, isn't this a problem? Because then they're just going to parrot it back to you."

2. Action Leads to Answers

Vance described action as a muscle, not a temperament. "It's not just about working long hours, even though sometimes it means working long hours. It's about doing the hard stuff and building that muscle."

That includes pushing through awkwardness with customers, mentors, and investors. His favorite example was the question most founders are too polite to ask in an investor meeting. "What's your biggest hesitation investing in us based on what you've heard?"

The point, he said, is to "put yourself in uncomfortable situations and collect as much information as you can."

1. Listen to Customers, Deeply

The number one lesson, Nick said, was the throughline of the whole session. "If you don't understand the problem space, if you're not really understanding what is necessary to understand the customer's value proposition that you're delivering and their willingness to pay... You may get customers, but you will lose them."

He shared a personal example that still stings. At his previous company, they instrumented their product with Pendo to see what customers actually used. He discovered that one of the team's most prized features, a sophisticated D3-powered interface, was barely touched. "I was heartbroken to see that the number of times that our customers had selected that feature and used it was like double digits. And I'm talking about six years of customer data."

The feature customers actually loved? A simple PDF generated at the end of a workflow.

His takeaway has stayed with him. "We could have built a lot less and gotten a lot farther if I had really keyed in to the customer's pain points."

The Throughline

One theme keeps surfacing: stay close to the customer, stay honest about what's working, and have the discipline to let go of what is not. Or as Nick put it, the customer is always at the center. The 10 lessons are different angles on the same truth.
