VERDICT

Should I use F6S?

Free network for founders: funding applications, startup deals, recruiting - f6s.com

Worth it. Worth using if you're an early-stage founder applying to accelerators or claiming software perks — it costs nothing. Don't expect the profile itself to deliver funding, users, or enterprise-grade assurances.
