Why Lefty users switch to Kolsquare

#1

No tracking caps

Lefty prices by the number of tracked talents, with caps per tier. Active teams reportedly hit the ceiling mid-campaign, and large seeding programmes then need extra paid capacity. Kolsquare applies no hard tracking caps. Campaigns scale without the extra cost.

#2

Transparent EMV you can defend

Kolsquare's EMV (Earned Media Value) runs on a transparent, published methodology based on the Ayzenberg Earned Media Value Index, the recognized industry benchmark for valuing social content, applied to continuously refreshed campaign data. Public Lefty reviews note reporting built on estimations rather than actual reach, a gap that matters when you report to clients. A number you can trace back to a published method is a number you can defend.

#3

Analysis and data depth across different verticals

Lefty's strength is concentrated in luxury and beauty. Kolsquare brings the same analysis and data depth across luxury, beauty, fashion, lifestyle, hospitality, DTC, FMCG, and more. Audience credibility scoring, EMV, benchmarking and content analytics work the same whatever the vertical, so multi-brand portfolios do not need one tool per category. Granular local and territorial creator discovery lets teams scout at country, regional and city level, whether the launch is in Paris, Milan or Los Angeles.

FAQs

Is Kolsquare cheaper than Lefty?

At single-licence entry, usually not: Lefty's plans have started around €590 per month for one user, one campaign, and 50 audience reports. The equation changes with scale. Lefty charges by the number of tracked talents, with tier caps, so teams running multiple campaigns and seeding programmes pay for upgrades or extra capacity as they grow. Kolsquare's flat per-seat pricing, with no tracking caps, tends to reach parity or beat it at mid-market and enterprise. Price against your real creator volumes, not the entry-tier plan. For UK teams running always-on influencer programmes, that's a meaningful difference: per-talent tracking caps are still the norm among competitors here.

Which is better for campaigns across Europe and the US?

Both platforms have European roots, so the difference is depth and reach, not geography. Kolsquare provides creator intelligence across more than 180 countries, including the US and Latin America, with particular depth across France, DACH, Iberia, Italy, the UK, Benelux and the Nordics. That includes local-language audience data, granular local and territorial creator discovery, compliance scoring in five markets (FR, DE, ES, IT, UK) and customer success in seven languages. For US brands expanding into Europe, it means one platform that already knows each market's creators, languages and rules. Lefty's centre of gravity is France and the luxury vertical, with support primarily in English. If you scout creators at city or regional level, or run campaigns across several countries, test both on exactly that.

How accurate is the reporting data on each platform?

Ask both vendors to show you actuals versus estimates on a live campaign. Public Lefty reviews note that reporting reflects estimations rather than actual reach and impressions, and that competitive reports are static snapshots. Kolsquare's reporting runs on continuously refreshed data with a transparent, published EMV methodology, and lets you correct or complete any metric manually, so client reporting stays accurate even when networks withhold data.

Can I connect Kolsquare to an AI assistant like Claude?

Yes, and with Kolsquare it works natively. Kolsquare is one of the first influencer marketing platforms to launch a native Model Context Protocol (MCP) connector, letting you query creator and campaign data directly from AI assistants like Claude and other MCP-compatible tools: campaign reporting, creator lookups and Listening summaries, with no exports or rebuilt reports. It launched in beta in July 2026 and runs on Kolsquare's verified data.

Is Kolsquare GDPR compliant?

Yes. Kolsquare is a European company and processes data in line with GDPR. Its creator intelligence is built on publicly available content and official platform APIs, and its responsible influence approach includes compliance scoring in five European markets (FR, DE, ES, IT, UK). Lefty, also headquartered in Europe, operates under the same regulation. Whichever platform you evaluate, ask how audience data is sourced, where it is processed, and how creator consent is handled. For UK teams, that includes compliance scoring built around UK GDPR and ASA disclosure rules specifically, not just the wider EU standard.
