I’m on a mission to inspire people to do more of what inspires them. 

None of us are truly self-made, we’re a collection of those who’ve supported and guided us along the way.

At Hubble, we believe one conversation can change everything. That’s why we built a platform where you can book 1:1 calls with the people who’ve actually done it…founders, investors, and operators from the best startups and funds. They share what they’ve learned, what they wish they’d known, and the mistakes you can avoid, so you don’t have to go it alone.

My journey into startups began in 2013, when I caught the entrepreneurial bug while working as a Private Wealth Manager at Wells Fargo Advisors, serving tech entrepreneurs in Silicon Valley. Since then, I’ve been living the founder life…building, scaling, raising capital, and mentoring others along the way.

Before my career in finance and tech, I played wide receiver in the NFL for the Philadelphia Eagles, San Francisco 49ers, and Chicago Bears. That experience taught me resilience, teamwork, and how to perform under pressure, lessons I carry into every startup I build.

When I’m not working, you’ll usually find me on the chessboard. If you’re on Chess.com, send me a challenge: kevj05.

Co-founder & CEO

Building a better way to discover and experience the best bars in San Francisco. Circles combines the best of Google Maps and Waze, providing real-time capacity updates and allowing users to request live video (called vibes) from venues before they arrive. Finding the right place to grab a drink is all about knowing the current atmosphere, that’s where we shine. 

Here are 13 new Angel Investors who just joined Hubble 💸 

If you’re raising your first round, start with angels...not funds. Angels move faster, usually do less diligence, write checks directly from their bank accounts, and back you just as much as the idea.

Everyone wants to be a founder...until they see the bill.

Truths every founder will learn (eventually):

- The first version of your product won’t work
- Your first launch… nobody will care
- Even the best founders are just winging it
- If it’s not a “hell yes,” it’s a no (for hiring)
- Momentum > Perfection...just start
- Funding is not what you need to begin
- If you think you do…you’re being lazy
- Customers will tell you what to build...listen
- A great product without distribution is a hobby
- “Overnight successes” 5+ years in the making
- Most of the journey is brutal...highs are rare
- When they hit, they’re worth everything
- Burnout is real...take a break
- Expect 100 no’s for every yes
- This journey will humble you...get ready
- Startups die before competition even matters
- Startups fail when momentum stops
- Raising money is a tool, not a milestone
- Perseverance is paramount...stay at it.

If you can’t handle this…starting a company isn’t for you. 

If you can...you’ve got a real shot. 💙

In 2023, I took a call with a kid who had nothing but courage and a wild idea.

He was a recent mechanical engineering grad who DM’d me asking if we could chat. He didn’t have a network in tech, didn’t know anyone in SF, and had no clue what the path looked like. He just showed up and asked if I’d talk to him.

A couple weeks later, we hopped on the phone. Over the next year, we probably had a dozen calls. He was living in Nebraska at the time, torn between staying in a stable job or leaving everything he knew to chase this idea he couldn’t shake.

Every time, our conversations circled back to the same thing:

“If you can’t stop thinking about it… that’s your sign. Go all in.”

Eventually, I think I convinced him to leave the Midwest and move to SF.

He left his job, packed his bags, and moved into a cheap Airbnb in East San Jose because he didn’t know the area at all. No glamor. No safety net. Just belief. A few months later he moved up to SF, plugged into the community, and started building momentum.

After two years of calls, we finally met up in SF...full circle moment. (see photo)

And here’s the wild part...the startup he wanted to build wasn’t some simple SaaS tool. It was a nuclear reactor that could power thousands of homes with virtually zero waste. True 24/7 carbon-free power.

I wasn’t sure if he was crazy or brilliant. Probably a little of both and I definitely told him that on a few occasions. 

Fast forward to today...Samuel Gibson and Hadron Energy, Inc. just merged in a deal valuing his company at over $1Billion. 

They’re going public on the Nasdaq in Q1.

Stories like this remind me why I always take the call, why I respond to people who reach out, and why I’ll always believe in betting on yourself. Good things take time. And sometimes they start with a DM from someone you’ve never met.

Proud of you, Sam. Keep going. The world needs what you’re building. 💙

Airbnb’s founders weren’t travel insiders.
Uber’s didn’t come from transportation.
SpaceX’s founders weren’t space engineers.
WhatsApp’s founders weren’t messaging execs.
Dropbox’s founders weren’t cloud vets.
Tesla’s founders weren’t EV incumbents.
Netflix’s founders weren’t media insiders.
Spanx’s founder wasn’t a fashion exec.
Hubble’s founders weren’t marketplace vets.

Startups are launched by generalist risk-takers and scaled by specialists.

Don’t let missing credentials convince you you’re not “ready".

...most founders weren’t.

Raising money isn’t easy. 💸 😤 

And if you only read LinkedIn headlines, you might think everyone else is closing rounds in their sleep.

The truth? Most founders are grinding through one of the toughest fundraising markets we’ve seen. Expectations have never been higher.

At Hubble, we’ll always be founder-first...helping you build, launch, and raise with real support, not vague advice.

So we teamed up with Boardy to bring you something special:

🚀 𝐓𝐡𝐞 𝐀𝐫𝐭 𝐨𝐟 𝐅𝐮𝐧𝐝𝐫𝐚𝐢𝐬𝐢𝐧𝐠 — 𝟐𝟎𝟐𝟔 𝐄𝐝𝐢𝐭𝐢𝐨𝐧

Featuring operators and investors who’ve been in the arena:

1. Bettina Briz — 40 years scaling tech from semiconductors → GoPro. Angel investor + board advisor helping founders raise and win.

2. Olivia O'Sullivan — Partner @ Forum Ventures. Builder of high-trust founder communities and deeply tapped into early-stage investing.

3. Erin O'Keefe Graham — Managing Partner & angel investor who builds high-growth teams from culture → leadership → performance.

4. Judah Longgrear — 3x founder with 2 exits. Now leading North America at Robot.com. Raised $50M+ and knows how to survive a fundraise.

The landscape is shifting...fast.

If you plan to raise in 2026, don’t wait to figure it out. This call gives you the roadmap founders rarely get access to.

And if you show up live…
Let’s just say there may be a few surprises waiting for you.

Cohort 25

People think raising $5M is the finish line. It’s not. It’s the start of a new journey.

I’ve been fortunate to help raise that much and I can tell you, it’s not easy in the slightest.

I still remember being fired up over a $5K check in the early days…that energy never goes away.

Part of that is why every month, we host a free online event with one simple mission. Help founders learn, level up, and keep going...especially when it feels impossible.

This month, we teamed up with Boardy to dig into a topic that’s always on founders’ minds.

🔥 Fundraising. 

What’s actually changing, what investors are thinking, and how to navigate this market with clarity and just a good down to earth real conversation that hopefully is helpful. 

These sessions aren’t about selling anything.
They’re about impact...real and raw conversations and real community.

Because we’ve all been in the desert before…
Trying to build, raise, survive, and somehow keep believing.

If you’re building, this is the room you want to be in.
