Tenacity

Founded by Devin Tyler

A marketplace where a company describes a piece of work in plain language and gets it done by vetted student freelancers in marketing, business or tech, with the scoping, the contract and the payment handled in between.

Where they are now

Over 100 startups registered.

Updated September 2026.

What they do

Between hiring somebody and signing an agency retainer there's a lot of work that never gets done. Tenacity takes that work, prices it up front and delivers it.

Who it's for

Companies that need discrete projects done without adding headcount. The site names startups, consulting firms, professional services, nonprofits and government contractors.

What's different

The price is fixed before the work starts, which is the opposite of how agencies bill. The site puts it at roughly a third of typical agency cost and says it accepts the top 5% of specialist applicants.


What they've done, with sources
Back a founder

Every Fifth Star company gets the same $25,000 check.

Contributions go into the fund that writes them. If Tenacity exits one day, our share comes back to the fund and goes out again, which is what makes us an evergreen fund.
