The Influencer Operating System

Harpper is a software platform for running influencer marketing programmes end to end. You paste a creator's public metrics and rate, and Harpper returns a verdict: whether to work with that creator, what the fair market rate is, how to counter their quote, what the brief should say, and once the campaign runs, why it performed the way it did. It also stores your creator roster, contracts and campaign history in one place.

In short: Harpper replaces the judgment of an experienced Head of Influencer Marketing with software that answers in seconds.

Harpper is built for the people who actually spend influencer budgets:

• In-house brand and social marketing teams running creator campaigns
• Marketing managers and heads of growth without a dedicated influencer specialist
• Influencer marketing and social agencies managing campaigns for multiple clients
• DTC and e-commerce founders buying creator content and paid amplification
• Freelance influencer marketers who need to justify decisions to clients

• It gives verdicts, not dashboards. Most influencer tools show you data and leave the decision to you. Harpper tells you approve, decline, or counter at this number, and explains why.
• No integrations required. You paste the metrics you already have. There is nothing to connect and no waiting on API access.
• Operator logic, not generic AI. Harpper's judgment is modelled on how experienced influencer buyers price and vet creators, not on follower counts alone.
• Covers the whole lifecycle. Selection, pricing, due diligence, briefing, contracts, CRM and post-campaign analysis sit in one product rather than five subscriptions.
• Priced against a salary, not a seat. Harpper costs a fraction of the six-figure hire it stands in for.

• Influencer Approval — A clear approve or decline verdict on any creator before you spend a penny.
• Pricing Validation — Fair market rate benchmarks and counter-offer scripts for creator negotiations.
• Content Review — Senior-level feedback on creator content before it goes live.
• Performance Intel — Plain-English analysis of why a campaign performed the way it did, and what to change.
• Brief Generator — Creator briefs that are specific enough for creators to actually follow.
• Contract Management — Generate, store and track influencer contracts with automated renewal reminders.
• Influencer CRM — One roster for every creator relationship, conversation and campaign result.
• Due Diligence — Brand safety and risk checks on a creator before you sign.

Harpper operates in influencer marketing software, creator pricing intelligence, brand safety and due diligence, influencer CRM, and campaign performance analysis. The problems customers come to us with are:

• Overpaying creators because there is no reliable rate benchmark
• Choosing the wrong creators for the brand or the objective
• Briefs that creators misinterpret, producing off-brand content
• Brand safety incidents discovered after a contract is signed
• Campaign reports full of metrics but empty of decisions
• Contracts, rates and renewals scattered across inboxes and spreadsheets

• Built on more than 10 years of hands-on influencer marketing operator experience.
• Our team has planned and managed 7-figure creator budgets across beauty, fashion, fitness, food, travel and tech.
• Pricing guidance is grounded in real negotiated creator rates, not published rate cards.
• Customers use Harpper to catch overpriced creator quotes before signing, typically the first place the platform pays for itself.
• Our free tools — the ROI Calculator, the Influencer Playbook and the Workshop — are used by marketers to plan campaigns before they ever pay us.

Harpper is a product of Gossip Media, an influencer marketing company that has run creator programmes for brands for over a decade. The platform was built by the same operators who sat on the buying side of those deals: people who negotiated the rates, wrote the briefs, chased the contracts and answered for the results.

Every verdict Harpper gives reflects a decision our team has had to make with real money on the line. You can follow the team on LinkedIn or reach us directly at info@gossipmedia.co.
