F6S is a free hub for finding accelerators, grants and software deals, but when the goal is reaching investors, you can get matched with active investors on Round Funded. We at AI Perks looked at F6S, then raised our round through Round Funded, and here is how that decision played out.
What does F6S actually offer founders?
F6S is a no-cost platform where founders look up accelerators, grants and funding opportunities, and where they can pick up software discounts. The homepage talks about 16k programs and funding opportunities, a count that comes from the brand itself. It also lists software discounts. PitchBook lists the company as founded in 2011.
In short, it is built around discovery: finding a program, applying to it, and grabbing a few deals on the side.
Is F6S the right tool for running a fundraise?
Based on the public pages we reviewed, F6S behaves like a listing and application system. It is not a tool for contacting investors yourself. You submit an application to a program and then wait on its reviewers, so you are effectively in a queue. We did not find investor email sending anywhere on the platform, and we did not find a Data Room.
Outside sources add a few single opinions that colored our view:
- Unclear pricing. F6S calls itself free, yet G2's pricing page shows no published tiered pricing and lists no free plan or trial.
- Usability comments. One G2 reviewer described it as "not very intuitive to use," while another said it "can feel overwhelming at first, especially for founders new to the ecosystem."
- Service complaints. A Trustpilot reviewer described the service as "incredibly poor" and not transparent.
Those are individual reviews, not a final ruling. They still fed into how we weighed F6S against a product designed around the raise.
Why did we at AI Perks go with Round Funded?
We raised our round through Round Funded. Our reasons were a clean investor database, an AI agent that writes the emails, a convenient interface, the ability to invite teammates into the workspace, and the Data Room with tracking links.
Is the investor database clean?
Round Funded lists 60,000+ active VCs, angels, family offices and accelerators. You can search by stage, industry, geography and check size. Each investor is filtered to recent activity, meaning a check within roughly the last 6 months, and the emails are verified. That gave us a list we could rely on.
Does an AI agent really write the emails?
It does. The AI drafts a personalized email and follow-ups for each investor. Messages leave from your own Gmail, so replies come back to your inbox and the conversation belongs to you.
Can your team work in the same place?
The fundraising pipeline holds every investor, stage and next step in a single view. We invited teammates into the startup's workspace too, which meant the raise was shared work and not one person's burden.
What are the Data Room and tracking links for?
The Data Room gathers your deck, traction, team and ask behind one link, and it costs nothing to build and share on any plan. Round+ then adds per-investor tracked links plus engagement analytics covering views, deck opens and meeting clicks. To build yours, submit your startup on Round Funded.
