Stop Overpaying Influencers
Today's featured startup is helping brands uncover audience overlap, cut wasted spend, and scale campaigns based on real incremental reach - not guesswork
Project Overview
Primetag is a platform that helps brands find the right influencers on Instagram and TikTok — fast, accurately, and with full performance analytics.
To make this possible, the startup built a powerful analytics engine that lets advertisers track ROI from influencer campaigns with the same clarity they get inside traditional ad platforms (impressions, clicks, conversions, growth metrics, and more).
The platform continuously gathers data on more than 10 million influencers, allowing brands to search by geography, niche, and even highly specific queries — like “Lady Gaga fans who traveled to Rome.”
Beyond influencer discovery, Primetag lets brands:
Explore high-performing posts by keyword, mentions, or hashtags
Review detailed stats for each influencer (impressions, likes, comments, audience reach, follower growth)
Save influencers to an integrated CRM and track all conversations and campaign history
Connect the platform to their sales system to measure not just clicks, but revenue, conversions, and full ROI
Monitor competitor activity in real time — including which influencers they’re using, content volume, and engagement levels
The company is based in Portugal and has raised €3.5M, bringing total funding to €5M. Customers include global names like Coca-Cola, IKEA, P&G, H&M.
What’s the Gist
Influencer marketing is massive — and still accelerating.
The market grew from $4.6B in 2018 to $16.4B in 2022, and surpassed $21B in 2023.
Naturally, influencer marketplaces began popping up everywhere — Stack Influence, Slice, and others — each adding their own twist to the same core idea.
What makes Primetag stand out?
Its biggest insight: audience overlap kills ad budgets.
Advertisers often assume that hiring two influencers with similar follower counts doubles their reach. In reality, if those creators work in the same niche and country, their audiences overlap — sometimes by 50% or more.
Meaning: the brand pays twice but wastes up to 25% of its budget on duplicated reach.
Primetag solves this by calculating audience overlap and showing:
How much unique reach each new influencer adds
The incremental cost of reaching additional unique users
When it makes sense to stop scaling before ROI collapses
This is something most influencer platforms surprisingly don’t provide — even in 2025.
Another notable insight: although Primetag was founded back in 2016, its latest funding round mentions using the money to “finalize MVP testing.”
A reminder that even 8-year-old startups can keep reinventing themselves and looking for new breakout opportunities.
Key Takeaways
Given the size and growth of influencer marketing, building a niche or specialized marketplace is still a promising direction.
But you need a unique feature — a differentiator. Today’s examples show just a few possibilities:
Stack Influence → barter-based payments with products
Slice → influencer CRM + financial infrastructure
Primetag → deep analytics and audience overlap modeling
That’s just the beginning.
Here’s a simple example of what could become a strong differentiator today:
An AI assistant that generates tailored ad copy for each influencer — based on what their audience reacts to most (phrases, angles, visual patterns, emotional triggers).
The market is still far from saturated.
Think: What feature would make you personally choose a platform to run influencer campaigns?
That’s exactly what’s worth building.
