What each agency actually does
What is SociallyIn
SociallyIn runs the whole of your social presence. An Atlanta agency founded in 2011, it handles social media management with influencer as one part of that, backed by an in-house production studio that makes the content rather than outsourcing it. For a brand that wants a single team to own its social channels end to end, from strategy through to produced posts, that full-service breadth is the appeal: influencer sits inside a broader social program rather than standing alone.
The trade for that breadth is that SociallyIn is not a self-serve tool for running influencer campaigns yourself. It is a managed agency, so you engage a team rather than log in to a platform, with influencer one thread in a wider social remit rather than the entire focus. That suits a brand that wants its social handled as a whole. If your specific need is a workflow to organise and run creator campaigns, a full-service social agency is a broader and different kind of engagement.
What SociallyIn does well
- Manages the whole social presence
- In-house production studio
- Influencer inside a broader program
- Established since 2011
Where it falls short
- Not a self-serve campaign tool
- Influencer is one part, not the focus
- A managed engagement, not a platform
- No published pricing and no self-serve search
What is Post For Rent
Post For Rent is a platform for running influencer campaigns. Founded in Amsterdam in 2015 by Gergo Csiszar, it pairs a campaign-management platform with agency services, so a brand can organise briefs, creators and delivery through the software or lean on the team. Its focus is the running of influencer work specifically rather than a whole social presence. For a brand or agency that wants a dedicated place to coordinate creator campaigns, that focused workflow is the reason to look at Post For Rent over a broad social shop.
The caveat is knowability and remit. Post For Rent publishes little, with no substantial client list to study first, so the read leans on a call and on trialling the platform. It is also not a full-service social agency, since managing influencer campaigns is its focus rather than owning your whole social presence or producing content in a studio. That suits a team whose need is coordinating creator work. If you want your entire social program run and made for you, a campaign platform is answering a narrower brief.
What Post For Rent does well
- Focused influencer campaign management
- Platform with an agency option behind it
- A place to organise briefs and delivery
- Operating since 2015
Where it falls short
- Minimal public data to assess
- Not a full-service social agency
- No in-house production studio
- No published pricing and no self-serve search
SociallyIn vs Post For Rent head to head
The choice is a broad social agency against a focused campaign tool. SociallyIn owns your whole social presence and produces content in-house, with influencer as one part, which suits a brand that wants its social handled end to end. Post For Rent is a platform and team for running influencer campaigns specifically, which suits a brand whose need is coordinating creator work. If you want the whole social program managed and made, the agency fits. If you want a workflow for influencer campaigns, the platform does. They sit at different widths of the same social space.
There is a step that serves the creator part of either, cheaply. Flinque indexes 10M+ verified creators across 4 platforms, each with a fake-follower score and 200 reported data points, at $0 to start and $49 a month after, so you can find and vet creators yourself first, then decide whether you need a full-service social agency or a campaign platform to manage them.
