John Haber on the First 30 Days: What Early-Stage Founders Get Wrong (and How to Fix It)
Editor

The first 30 days of building a startup are messy. Founders move fast. Ideas shift daily. Most teams think they are making progress. Many are just adding complexity.
John Haber has spent years working with early-stage founders on exactly this phase. As the founder of a Montreal-based advisory firm focused on product clarity and onboarding, he has seen dozens of startups stall before they ever gain traction. His work centers on one idea: most early problems are not technical, they are about confusion.
“Every founder thinks they need to build more,” he says. “In the first month, they usually need to cut more.”
That mindset shift changes everything.
Mistake #1: Building Before Explaining
Many founders start with features. They jump into product mode. They build dashboards, tools, flows. Then they try to explain it later.
It rarely works.
Data shows that 42% of startups fail because there is no real market need. That problem often starts with unclear thinking, not bad execution.
Haber recalls working with a founder who spent three weeks building a full workflow system for small agencies.
“It had task boards, reporting, notifications,” he says. “I asked him to explain it in one sentence. He couldn’t. That was the issue.”
They paused development. They rewrote the positioning. The product shifted from “workflow system” to “client update tracker for agencies with multiple stakeholders.” The difference was immediate.
Fix:
Write a one-sentence explanation before building anything. If it takes more than 10 seconds to say, it’s too complex. Test that sentence with real people. Watch for confusion.
Mistake #2: Ignoring the “First Win”
Most founders think about long-term value. They talk about what the product will do after weeks or months of use.
Users don’t think that way.
Research shows that 55% of users abandon a product within the first week if they don’t see value quickly.
Haber calls this moment the “first win.”
“It’s the first time a user feels like, ‘Okay, this actually helped me,’” he says. “If that moment doesn’t happen fast, they leave.”
He worked with a startup that required users to set up five steps before doing anything useful. Most never finished setup.
“We cut it down to one action,” he says. “Upload one file. See one result. Retention improved within days.”
Fix:
Design for one simple action that creates value fast. Remove anything that delays that moment. Track how long it takes a new user to reach it.
Mistake #3: Talking to the Wrong People
Founders often ask friends for feedback. Or they talk to people who are not actual users.
The feedback sounds positive. It’s not useful.
“You hear things like ‘This is cool’ or ‘I’d use this,’” Haber says. “Then you launch and nobody shows up.”
He remembers a founder building a scheduling tool for fitness coaches. Early feedback came from other founders and friends.
“We told him to talk to five real coaches,” he says. “Within two conversations, he realized they didn’t need scheduling—they needed client retention tools.”
The product direction changed completely.
Fix:
Talk to real users early. Ask them about their current process. Look for pain points, not compliments. If they don’t care, that’s important data.
Mistake #4: Overloading the Product
There is pressure to impress. Founders think more features make the product stronger.
It often does the opposite.
Studies show that feature-heavy products increase user drop-off during onboarding by up to 30%. More options create more hesitation.
“Founders try to show everything at once,” Haber says. “Users don’t want everything. They want the next step.”
He worked with a team that had built eight core features. New users didn’t know where to start.
“We hid six of them,” he says. “We showed one clear path. Usage went up right away.”
Fix:
Start with one core use case. Hide or remove anything that distracts from it. Add complexity later, once users understand the basics.
Mistake #5: Moving Too Fast Without Direction
Speed feels productive. Founders ship quickly, test constantly, pivot often.
Without direction, chaos ensues.
“Speed without clarity just creates more problems faster,” says John Haber, Montreal, “You end up building three versions of something you didn’t need in the first place.”
He describes working with a team that rebuilt their onboarding flow four times in one month.
“They kept changing it based on opinions,” he says. “No clear goal. No baseline. Just reacting.”
They stopped. Defined one metric: time to first win. Then they tested changes against that.
Fix:
Pick one goal for the first 30 days. Track it closely. Make changes based on results, not opinions.
Mistake #6: Avoiding Simple Messaging
Founders often use complex language. They describe their product in abstract terms.
It sounds impressive. It confuses users.
“There’s a tendency to sound smart instead of being clear,” Haber says. “Clear always wins.”
He shares an example of a startup describing their product as a “collaborative workflow optimization platform.”
“We changed it to ‘a tool that helps teams track client updates in one place,’” he says. “Conversion improved right away.”
Fix:
Use plain language. Describe what the product does, not what it could become. Test messaging with people outside your industry.
What Founders Should Do Instead
The first 30 days are not about scale. They are about understanding.
Focus on:
- Clear positioning
- One simple use case
- Fast user value
- Real conversations with users
- Measurable progress
Everything else can wait.
Haber puts it simply: “If someone can’t understand your product in 15 seconds, they won’t use it for 15 minutes.”
Why the First Month Can Make or Break Everything
Most startups don’t fail because of bad ideas. They fail because they build too much, too fast, without clarity.
The first month sets the tone. It decides whether a product feels simple or confusing.
The founders who get it right don’t rush to impress. They focus on making one thing work well.
“Early on, you’re not building a company,” Haber says. “You’re building understanding. Once that’s clear, everything else gets easier.”
