The leading Zoom-based program.
The 4thly Accelerator.
Silicon Valley expertise, with no travel requirements or equity dilution.

Conducted entirely live via Zoom, the 4thly Accelerator is an intensive experience designed to get your startup to the next level.

You keep 100% of your equity.

Unlike most startup accelerators, we do not take equity. Instead, you pay a simple program fee. We’re interested in your success, not taking your equity.

Led by experts.

The program is led by Silicon Valley expert Bret Waters, based on a proven process developed during his experience as a Silicon Valley entrepreneur and his work at Stanford University.

Immersive experience.

You will have Zoom meetings 3x/week with the entire group, plus 1:1 meetings with Bret and his team of experts. This mix of group collaboration plus 1:1 coaching is part of what makes the 4thly experience unique. The program also features expert guest speakers from various disciples.

Cross-pollination is the secret sauce.

The greatest value you get from the program may be from interaction with the other participants. We carefully select participants who we believe will add to the experience for all.

Not just for tech startups.

We always try to admit a balanced cohort consisting of entrepreneurs in many different geographies and sectors.

Demo Day with Venture Capital Investors

On the last day of the program we hold a “Demo Day” where each startup delivers their pitch to an audience that includes Silicon Valley investors, venture capitalists, and executives.

Quotes from previous participants:

“Our experience with 4thly’s cohort was everything we could have hoped for in an accelerator. Not only did we move our idea forward, but we came away with lasting friendships and expanded networks that will continue to pay dividends far into the future”. 

“The 4thly accelerator helped us focus on the Customer Development process, which saved us months of time & thousands of dollars being wasted on the wrong solution. We strongly recommend it for all startups that are trying to get to the next level”. 

“The 4thly accelerator was a great opportunity!! It came at a crucial moment for me and was an experience that will be with me for my whole life. It gave me give confidence that I can and must build great global product!” 

We had been working on our startup for some time, and were nearly ready to launch. But the two months we spent in the 4thly Accelerator, immersed on Zoom with the amazing 4thly team and the other participants, got us over the finish line. We now feel truly prepared for launch, and our startup is ready for success”.

Being a part of the 4thly Accelerator was a truly insightful experience, with all things startup! We learned a great deal from the 4thly team, the guest coaches and a diverse cohort of extremely smart startup founders. I highly recommend it for startups looking for structured accelerated growth.”

The support we received in the 4thly accelerator was amazing.  It felt as if everyone in the 4thly ecosystem — leadership, colleagues, advisors, and even the frequent guest speakers — were all on our team and in our corner helping us to be successful.”.
