90 Days with Hansel: Lessons from the Frontlines of an Early-Stage AI Startup

 
 

Hansel.ai Has A Vision That Matters

Hansel, an early stay startup, is tackling a timely and urgent crisis: the epidemic of social isolation. Research from experts like Jonathan Haidt, Surgeon General Vivek Murthy, and Casley Killam shows that chronic loneliness is incredibly detrimental to our health, and can be more dangerous than smoking 15 cigarettes a day.

Hansel’s mission is ambitious and deeply human: to deepen real-life social connections through technology. 80% of people who heard even the first 20 seconds of the elevator pitch were wholeheartedly on board with the vision and mission.

At its core, Hansel is building an AI-powered “social secretary”: a lightweight agent that integrates with platforms like iMessage or SMS to help users turn intent into action. Whether it's planning a coffee catch-up or reconnecting with old friends, the agent is designed to make real-life meetups easier and more intentional.

The founder of hansel lives and breathes this mission. She has long rejected the culture of digital distraction, has been off social media for over 10 years, and has built her life around meaningful in-person connection. That ethos gives Hansel’s brand a rare kind of authenticity. Take note, founders!

The business model is equally thoughtful. While the product is intended to be initially free for consumers, Hansel will also eventually offer a B2B solution for teams and employers, basically positioning the tool as a social wellness benefit for workforces. After all, it’s been observed that people who get to know each other personally ultimately have more successful working relationships. A healthcare organization with 500+ employees even signed a letter of intent to pay $50 per seat—a strong signal of demand and viability.


When the Future Comes Too Fast

In Pattern Breakers, investor Mike Maples Jr. writes:

“To start a great company, you must live in the future.”

But many early-stage founders try to live in the future before validating the present.

When I joined Hansel as a product advisor, the tiny and mighty team had already invested in projections, acquisition strategies, and pitch decks. They had run a small survey (~30 responses) and conducted early user interviews that shaped the company’s messaging and made its way into pitch decks. A hard-coded prototype existed, but it was fragile and not yet usable for meaningful testing.

One of my first contributions was helping the founder define the MVP and stand up a knowledge base for a small tech team. We aligned on a product requirements document and a clear feature scope. But much of the company's energy remained focused on theoretical growth—CAC, LTV, waitlist conversions—rather than real product interaction.

As Lean Startup’s Steve Blank said: “No business plan survives first contact with customers.”

Validation doesn’t happen in spreadsheets. It happens through user behavior, feedback (quantitative and qualitative), and iterations.


What Was Missing?

The problem Hansel aims to solve is legitimate. The founder is deeply committed. The opportunity is real.

However, during my eventful and short engagement, the company had yet to build the product infrastructure to support learning or momentum (aka, Product-Led-Growth). A coded demo was built before any UI design work was done. It’s no secret that designs, including high-fidelity mockups, are typically faster, cheaper, and easier to iterate on than code. The founder had worked independently on this demo, and the backend was being hard-coded without prior discussion, in a vacuum, by former engineering colleagues volunteering their time. As new team members joined as partners, this approach felt neither transparent nor collaborative. The key gaps I started observing included:

❌ No testable prototype in the hands of users

❌ No continuous feedback loop

❌ A waitlist campaign without anything to adopt

❌ Conversations around CAC and LTV, but no real usage data

❌ A focus on finding a technical co-founder before defining the technical scope


These missteps are common, especially among founders with strong marketing or brand backgrounds who haven’t fully embraced what top voices and experts in Silicon Valley call the product discovery mindset. It was Marty Cagan who popularized this mindset among larger tech organizations looking to be more product-focused. I’ve seen these missteps occur in an almost repeatable pattern since I first joined a startup back in 2010.

Consider the power and the knowledge that comes from having users get to know your product.

“You can’t validate your idea without a product experience. And you can’t validate a product experience without users.” — Marty Cagan, Inspired

During my time working on Hansel, I was getting considerable pushback about addressing the gaps I mention above, and I actually assumed it was my own blindspots getting in the way. 

I also recruited a senior engineering advisor—a very accomplished individual I had worked with before—who dramatically improved the demo in only a couple of weeks. But his contributions went under-recognized. In retrospect, this reflected a broader challenge: the value of product and technical partners wasn’t yet fully understood.


Key Takeaways for Pre-Seed Founders

Building a startup at the pre-seed stage is an exercise in disciplined exploration. It’s easy to get swept up in the vision, the storytelling, and the strategies about how to acquire customers. But none of that matters without an existing product. What Hansel reminded me is that strong ideas need structure, and passionate founders need partners who can help them turn conviction into an actual product that can help you learn more about what your customers will ultimately need from you. Founders need Product people to remind them of the power of Product-Led-Growth. Here are the lessons I took with me—and the ones I now bring to every early-stage team I work with.

🛠 Build Before You Broadcast

This is the most important one. Don't build a funnel or grow a waitlist before you've built something people can actually use.

🎨 Invest in Product & UX Early

Hire someone who can prototype, test, and gather early signals before spending on paid marketing.

💡 Don’t Lead with CAC & LTV

Metrics are useful—but only after real usage exists. Strategy is not a substitute for signal.

🚫 Early Adopters Need Something to Adopt

A compelling vision is a great start, however you need a usable product to convert early interest into real feedback.

📈 Embrace Product-Led Growth

Skip the splashy launch. Focus on getting a few users to love your product and build from there.

👥 You Don’t Need a Technical Co-Founder (Yet)

You need someone technical enough to build, iterate, and learn with you. They should be local or timezone-aligned—not an offshore team taking orders from a non-technical founder.

🚀 VCs Want Proof, Not Promises

Especially in AI, healthtech, and cybersecurity, the bar is high. A beautiful deck won’t beat live user engagement.


Closing Thoughts

Hansel.ai is tackling a meaningful, modern problem with conviction. During my engagement, I saw the message sharpen and the ambition grow. I also witnessed familiar early-stage pitfalls—ones that can be avoided with the right approach to discovery and validation.

If you're building something new:

  • Start small

  • Build something usable

  • Get it into real hands

Live in the future, but validate in the present. That’s a proven way to build something that lasts.

What Is a Product Manager—and Why Your Startup Can’t Thrive Without One

Let’s pretend you’re the star of what critics are already calling the next big blockbuster. You’ve shown up every day: learning your lines, hitting your marks, going full glam in the makeup chair. The cameras are rolling, the lights are on, and the set is buzzing. But then it hits you: You have no idea who’s producing the film? In fact, you’re not sure there even is a producer.

You start to notice that some scenes feel off, others are electric, but no one seems to be steering the ship. No one's capturing what’s working, or fixing what’s not. And just when you think it can’t get more confusing—you realize you don’t even know who’s signing your paycheck.

No ask yourself, what are the chances this movie becomes a hit?

If you're building a startup, chances are you've got vision, grit, and a killer idea. Kind of like a Hollywood producer! You may even have a functioning prototype of your product. But if you’re missing a strong Product Manager (PM), you're likely missing the glue that holds vision and execution together.

Product Managers are the connective tissue between strategy and ship date. They don’t just keep the trains running—they make sure the train is going somewhere worth going, with passengers who actually want to be there.

🎯 Not a Feature Builder—An Ambassador of the Customer

Let’s get this out of the way: great Product Managers do not run feature factories.

They don’t just take orders from stakeholders or chase down every customer request. The most important contributions that PMs can make are customer-focused. PMs are relentless about understanding the customer—what they’re trying to do, what’s getting in the way, and what would make their experience better.

They balance stakeholder input with user research, behavioral data, and market signals. Because if no real customer wants or needs what you're building… what’s the point?

In other words: no viable customer = no viable product.

One of the reasons I love the Product-Led Growth mindset is because PLG turns real user value into your best acquisition engine. Unlike gaming a waitlist or chasing CAC hacks, PLG compounds—every great product moment becomes a marketing moment.

🧩 Alignment Is the Real (Hardest) Job

If there’s one thing PMs must do exceptionally well, it’s driving alignment across a cross-functional team. Getting people to disagree and commit, not by forcing consensus, but by guiding teams to agree to disagree productively, and still move forward.

Thinking back to our Blockbuster hit analogy:


The PM is the producer of your blockbuster product—managing timelines, talent, budget, and creative vision, all while ensuring the audience (or customer) loves the final cut.

🛠️ Translators of Vision to Execution

A great PM speaks both “engineering” and “executive.” They bridge the gap between customer need, business goal, and technical feasibility.

They translate abstract ideas into clear requirements that are influenced by:

  • Customer research and feedback

  • Business KPIs and strategic goals

  • Technical constraints

  • Competitive and market landscape

They don’t micromanage how the solution gets built—but they’re crystal clear on what and why.

📈 They Scale with Purpose

Launching a product is only the beginning. PMs know how to define and deliver an MVP, then scale it with purpose. They track the right signals, instrument the product from day one, and iterate based on real user behavior—not just gut feelings.

Because shipping your MVP and creating buzz don’t define success. Adoption and improvement do.

🧭 Ruthless Prioritization, Strategic Rationale

Every startup has more ideas than time. Product Managers are trained prioritizers—they make tough trade-offs, guided by both data and instinct. As a Product Manager, you need to know when to say “not yet”, “let’s put that on the back burner”, or “no” to features that don’t ladder up to agreed-upon goals. And they say it with empathy, clarity, and a plan forward.

🚀 It’s Not Just About Shipping—It’s About Launching and Landing

PMs are deeply involved in go-to-market strategy. They collaborate with marketing, sales, and customer success to make sure the product not only ships—but lands well. PMs should be conversations discussing the Go To Market plan. Why? Because they will need to align internal teams, craft clear messaging, and ensure feedback loops are tight so the product continues to evolve. Because success isn’t just usage—it’s engagement, love, and longevity.

So… Why Does This Matter for You?

If you’re a VC, technical co-founder, or visionary founder wondering why a product isn’t gaining traction, ask yourself:

👉 Do we have strong Product leadership?

Because tech without product is potential without a plan.
And vision without product is a great idea that no one ever uses.

Bottom line, if you want your startup to scale with clarity, speed, and customer love, then don’t build without Product.

My Top 10 Book Recommendations for Startups and Product Leaders

📚 Influential Reads to Help You Build Smarter, More Person-Centered Products

During my nearly ten years working at startups—ranging from seed to Series B—I hardly made time to read career books. After long hours at my computer or talking with colleagues in conference rooms, I usually chose to unwind with a good Pandora station or Spotify playlist. Eventually, I got into podcasts during my San Francisco commutes. But in hindsight, I wish I had spent more time with the books written by the people who shaped our industry.

There’s no better way to reset your mindset, unlock powerful insights, and find inspiration than by reading. Whether you're launching your first MVP, scaling a team, or trying to crack Product-Market Fit, the right advice at the right time can change everything.

As a product advisor and fractional CPO, here’s a stack of books I return to again and again—for myself, for my clients, and for anyone trying to build meaningful, successful digital products.

1. The Lean Startup by Eric Ries

I had the fortune and honor of having Eric’s team come to LendingClub and run workshops during my time as a Director of Product for platform services. The lean startup methodologies are timeless. This is the modern classic that introduced validated learning, the Build-Measure-Learn loop, and lean experimentation to a generation of founders and a massive generation of enterprises undergoing digital transformation. Still one of the best frameworks for reducing waste and building something people actually want—especially when resources are tight.

Great for: Founders, first-time builders, and anyone iterating on an MVP—even inside a Fortune 500.

2. Product is Hard by Marty Cagan

Silicon Valley Product Group hosted workshops for our leadership team at LendingClub in 2017, and I still refer back to those notebooks. This book is a no-fluff, candid set of essays from the legendary product thinker behind Inspired and Empowered.

Great for: Product leaders, startup execs, and founders scaling product teams.

3. Continuous Discovery Habits by Teresa Torres

Teresa Torres is a national treasure. Her book is a must-read for embedding discovery into your organizations. Torres makes a strong case for weekly touch-points with customers and shows us how to turn insights into actionable outcomes through one of my favorite topics to teach on:, the OST: Opportunity Solution Trees. I referenced many of Teresa Torres’ principles and teachings in my own lectures and workshops at Product School.

Great for: PMs, researchers, and cross-functional teams focused on learning and iterating.

4. Pattern Breakers by Mike Maples Jr. and Peter Ziebelman

I learned about this book at a Floodgate Ventures event. It’s a deep dive into how “thunder lizard” startups—those that fundamentally reshape industries—are built. My favorite takeaway? The concept of finding your co-conspirators who share your mission to reshape the future.

Great for: Visionary founders, early-stage investors, and product leaders building category-defining companies.

5. The Elements of User Experience by Jesse James Garrett

I often use this book in coaching sessions and UX workshops. It introduces the five planes of UX—from strategy to surface—and remains relevant across web, mobile, and AI-based experiences.

Great for: Product professionals collaborating with design or anyone needing a strong UX foundation.

6. The Field Guide to Human-Centered Design by IDEO.org

My introduction to IDEO's approach began back in 2009 at Tellme Networks. Their book and workshop materials were everywhere in the office and many of their principles guided the building and deployment of cutting-edge IVR technology that we were developing at the time for Microsoft. More than a book—it’s a hands-on, step-by-step toolkit for applying human-centered design in the field. It’s especially useful for teams doing discovery in complex systems, underserved markets, or social impact spaces.

Great for: Teams doing discovery in complex systems or building for social impact.

7. Fire: Inexpensive, Restrained, and Elegant Methods Ignite Innovation by Dan Ward

This is a favorite among scrappy product builders. Ward’s FIRE method—Fast, Inexpensive, Restrained, Elegant—challenges the idea that more time and money always lead to better products.

Great for: Lean startup teams, innovation leads, and anyone operating under tight constraints.

8. Bonus: Listen While You Work

If you're like me, juggling meetings, workshops, and long walks with the dog—consider grabbing the audiobook or Kindle versions. Many of these titles are available in both formats, so you can absorb wisdom while you're on the move.
