The detail

What each agency actually does

What is SociallyIn

AtlantaFull-service socialIn-house studioSince 2011

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

AmsterdamPlatform and agencySince 2015Campaign management

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.

FAQs

Common questions about SociallyIn and Post For Rent

What is the difference between SociallyIn and Post For Rent?
SociallyIn is an Atlanta full-service social agency running your whole social presence, with an in-house production studio and influencer as one part. Post For Rent is an Amsterdam platform and agency for managing influencer campaigns specifically. One owns social end to end. The other is a focused influencer-campaign tool, so they suit very different briefs.
Does SociallyIn only do influencer marketing?
No. Influencer is one thread inside a broader social program, since SociallyIn manages the whole social presence and produces content in its own studio. A brand that wants only a workflow to run creator campaigns gets more than it needs here. SociallyIn fits when you want social handled end to end, whereas a focused influencer tool like Post For Rent suits a narrower brief.
What does Post For Rent's platform do?
It pairs an influencer campaign-management platform with agency services, so a brand can organise briefs, creators and delivery through the software or lean on the team, from Amsterdam since 2015. Its focus is running influencer work specifically. That is narrower than SociallyIn, which owns a whole social presence and produces content, rather than concentrating on a creator-campaign workflow.
Which suits a brand wanting its whole social run?
SociallyIn, clearly. A brand that wants one team to own strategy, posting, production and influencer across its social channels gets a full-service agency built for that. Post For Rent concentrates on influencer campaign management rather than a whole social presence, so for end-to-end social the agency is the far stronger fit while Post For Rent suits a focused creator brief.
Which suits a team running influencer campaigns?
Post For Rent, since managing creator campaigns is its whole model. A brand or agency coordinating briefs, creators and delivery gets a platform and team built for that. SociallyIn folds influencer into a broader social program rather than offering a dedicated campaign workflow, so for the coordination side Post For Rent is the closer fit while SociallyIn suits full-service social.
How transparent are they to assess?
Neither publishes much. SociallyIn keeps a thin public record behind its full-service positioning, while Post For Rent publishes little with no substantial client list, so both decisions lean on a call and references. For SociallyIn, ask to see produced work from its studio; for Post For Rent, trial the platform and speak to contactable clients before scoping.
How much do they cost?
Neither publishes pricing. SociallyIn quotes a full-service social engagement, while Post For Rent quotes based on platform and agency use. So costs only firm up once each scopes your brief, which makes them hard to compare against each other or against a self-serve tool with published tiers up front.
Is there a software alternative to both?
Yes. Flinque is self-serve software covering discovery and vetting, indexing 10M+ verified creators across 4 platforms with 200 data points per creator reported on each profile. There is no demo and no annual lock-in. The Free Plan is $0, Starter is $49 a month and Enterprise is $150.
