We're an agency, so read this knowing that. But we've also watched a lot of brands come to us after a platform campaign didn't work, and a few for whom a platform was genuinely the right call. Here is the difference, as plainly as we can put it.
What a self-serve platform gives you
A database of creators searchable by follower count, niche keywords and price; a messaging tool; sometimes a payment escrow and a basic report. You do the strategy, the casting, the briefing, the chasing and the analysis. Fees are low - typically a subscription or a small percentage per booking.
It works when: your product is simple and visual, you have someone in-house with time to manage 10 to 30 creator conversations, you're seeding for reviews rather than driving a sales target, and you already know which creator archetype works for you.
What an agency gives you
- Knowing who converts. Four years and 1,300+ Singapore creators of post-campaign data: which archetypes deliver in skincare vs furniture vs finance. A platform shows you followers; it can't show you who actually sold.
- Briefs written to convert. A hook, one objection to dismantle, one proof point - per creator. Most platform briefs are "post about our product, tag us".
- Relationships. A campaign manager who has briefed and paid these creators before gets faster replies, better content and fewer no-shows. On a platform you're a stranger.
- The paid layer. Turning the winning posts into ads is where campaigns become profitable (Mom's Cooking 16x return on ad spend). Platforms stop at the organic post.
- Measurement. Landing pages, pixels, per-creator codes and a report against the metric you agreed.
- Time. A 20-creator campaign generates 60+ touchpoints. Either your team handles them or ours does.
Side by side
| Self-serve platform | Agency | |
|---|---|---|
| Upfront cost | Low - subscription or per-booking fee | Higher - minimum engagement covering strategy, casting, management, amplification |
| Your time | High - you run everything | Low - approvals only |
| Casting quality | Keyword and follower-count matching | Human-picked from campaign data and relationships |
| Brief quality | Yours | Conversion-structured per creator |
| Paid amplification | Not included | Built in - winners become ads |
| Reporting | Views and likes | Against the metric you agreed; per-creator cost per result |
| Best for | Simple products, small seeding, in-house capacity | Sales or lead targets, launches, events, multi-market, regulated categories |
When to use which
Use a platform if: you're spending under S$2,000, you want reviews and content more than sales, you have a marketer with 10 hours a week to run it, and you're comfortable that the first round is a learning exercise.
Use an agency if: you have a sales, lead or footfall target; the launch or event has a date; you're in a regulated category (finance, health, alcohol); you're running in more than one market; or you've already tried a platform and the content was fine but nothing sold.
The hybrid nobody talks about: use an agency for the first two campaigns to learn which creators and formats convert for you, then take the shortlist in-house for always-on seeding. We'd rather you do that than never start.
The question to ask any agency
"Which creator archetype converts in my category, and what's your evidence?" If the answer is a media kit or a follower number, it's a platform with a markup. If the answer is "in home and living, mid-tier interior creators drive shares and micro reno-diary creators drive saves - here are two campaigns", you're talking to people with data.
Also ask who picks the creators. If it's an algorithm, you're paying agency fees for platform work. Every creator on our campaigns is hand-picked by a campaign manager; that's the whole point.

Take the 2-minute quizFrequently asked questions
Is a self-serve influencer platform cheaper than an agency?
Upfront, yes. Per result, often not - platforms don't include strategy, conversion-structured briefs or paid amplification, which is where campaigns become profitable. Add your team's time managing 10–30 creator conversations and the gap narrows.
When should a brand use an influencer marketing agency?
When there's a sales, lead or footfall target; a launch or event date; a regulated category; more than one market; or when a platform campaign produced content but no sales. For small seeding with in-house capacity, a platform can be enough.
What does an influencer agency actually do?
Strategy and audience definition, creator casting from campaign data and relationships, conversion-structured briefs, content management and approvals, paid amplification of winning posts, and reporting against an agreed metric.
Do influencer agencies use AI to pick creators?
Many do. Social Jet does not - every creator is hand-picked by a campaign manager who has worked with them before, then approved by the client. AI matching is follower-and-keyword lookup, which is what a self-serve platform already gives you.
