Introduction
House of Marketers and inCast are both managed influencer marketing agencies, so comparing them is a question of focus and region rather than software you sign into. House of Marketers is a TikTok-led agency in London founded by early TikTok staff. inCast is a full-service agency reported to be based in Sao Paulo, Brazil, with work spanning Latin America and the United States. Both run campaigns for you rather than hand you a tool.
This page sets out what each agency does, where it sits and who it has worked with, using only publicly stated detail. Neither publishes a creator database size or a rate card, since both sell done-for-you services rather than self-serve access. Every figure here is reported and worth confirming directly. At the end we cover where Flinque fits as the self-serve software alternative to both.

What House of Marketers is
House of Marketers is a full-service influencer agency in London that leans hard into TikTok. It was founded by early TikTok staff, which is the root of its TikTok-first positioning and its pitch of insider platform knowledge. Its publicly stated clients include Rimmel London and HelloFresh, pointing at consumer brands that want short-form creator campaigns delivered end to end.
Like most agencies the public detail stops there. House of Marketers does not publish a creator database size or a rate card, so you engage it as a service and agree scope in a conversation. That suits a brand that wants hands-on TikTok expertise rather than a platform to operate. It is a weaker fit for a team that would rather run discovery and vetting itself across several networks.

What inCast is
inCast is a full-service influencer marketing agency reported to work out of Sao Paulo, Brazil, running campaigns across Latin America and into the United States. Its publicly stated clients include Heineken, BMW, Amazon and Samsung, a roster that skews toward large multinational brands rather than small teams testing the channel. As a managed agency it owns strategy, creator selection and delivery so nobody on your side operates any software.
Beyond that public detail is thin. inCast does not disclose a creator database size, a feature set or any pricing. Even its base is reported inconsistently since some directories list Los Angeles rather than Brazil. Read it as a done-for-you partner you brief rather than a product you log into. If a LatAm and US influencer push is the goal it has the regional story, though the specifics only surface in a sales call.

Head to head
The choice here is about region and channel, not tooling. House of Marketers is the sharper pick if TikTok is the whole plan and London is a workable base, since its team came out of TikTok itself. inCast is the stronger option if you need influencer reach across Latin America and the US from a partner that works in those markets daily. Both are done-for-you services though, so neither hands your team software to run campaigns without an agency in the loop.
Where each one leaves a gap
The trade-offs are clear.
- House of Marketers keeps the usual agency details private, so there is no public database size, feature list or pricing to weigh before a call. You are buying a service on reputation rather than a spec sheet.
- Its TikTok specialism is also its ceiling. A brand that needs strong reach on Instagram, YouTube or X may find it narrower than a full-service label suggests, so confirm scope before you commit.
- As a managed service it means agency fees and a scoping process rather than a login. That is fine when you want delivery handled though limiting if your team wants to search and vet creators directly.
- inCast publishes very little. Even its headquarters is reported inconsistently between Brazil and Los Angeles, so it is harder to know exactly what you are signing up for before a sales conversation.
- There is no public creator database size or rate card, so you cannot compare it on numbers. The detail arrives only once you are already in a pitch.
- inCast runs campaigns for you, so it does not give an in-house team a tool to find and vet creators on demand. Teams that want that control need software rather than an agency.
Where Flinque fits
Flinque is the self-serve software alternative to both. Instead of hiring a team to run campaigns, you search and vet creators yourself in a platform with a reported 10 million-plus verified creators across Instagram, TikTok, YouTube and X, spanning a reported 25-plus countries. Every profile carries a reported 200 data points and a fake-follower check, with 12 filters across creator and audience data.
If you want a partner to own delivery, House of Marketers and inCast are both credible managed choices depending on whether you lead with TikTok or LatAm reach. But if you would rather find verified creators yourself on four platforms with a price you can see and no demo or annual lock-in, that is what Flinque offers at a flat Free of $0, Starter at $49 a month or Enterprise at $150 a month.
