Gainsty
Gainsty, as it presents itself, is for people who want growth handled for them, with a dedicated account manager on its higher plan.
Flock Social
Flock is for people who want to choose the accounts and hashtags their audience follows, and let automation build a steady base of real followers.
These are Gainsty's own statements, read on its public site on 2026-11-13:
We have not verified these claims. Check its site for current details.
Both services sign in to your account and engage with an audience on your behalf. The difference is in how: Flock is automation you set up yourself, by choosing the accounts and hashtags your audience already follows, with live support 24/7 on both plans and published estimates instead of a guarantee.
Flock finds the audience that fits your account, then engages with those people through automation until a steady follower base builds. Flock engages only with real, active accounts that match your niche, and it never uses bots or fake followers. It never unfollows accounts you followed yourself, and secure multi-proxy login protects your account.
Both plans include follow/unfollow automation, auto-like after follow, real-time growth analytics and weekly Instagram audits; IG Adventurer adds welcome DM automation and the Close Friends auto-adder. Plans start at $69 a month, or $34 a month billed yearly. Plans differ in estimated monthly growth, and those estimates are never a guarantee.
