Silicon Valley’s leading Zoom-native startup accelerator.

While I had high expectations going into the program, the 4thly team collectively and individually exceeded them with ease. The passion for assembling a great accelerator program and giving back via knowledge and valuable insights, mentors, and coaches was really tremendous”. -Fintech Founder NYC (raised $3M after program)

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 the 4thly 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 disciplines.

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 investorss

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.
