What is Seiza?

Seiza is a Paris-based social recruiting platform that helps employers run job ads on Facebook, Instagram, Snapchat and TikTok and collect the resulting applications. According to industry profiles, the company was founded in 2010 as Work4 Labs and renamed Seiza in 2022. In November 2024, the job search engine Adzuna announced its acquisition of Seiza.

According to the acquisition press release, Seiza serves more than 400 clients, including McDonald's, Sysco, Ecolab and Veolia. That makes it one of the largest established social recruiting providers in high-volume hiring.

Who is Seiza for?

Seiza targets employers with many locations and recurring hiring needs. According to industry profiles, the sectors include hospitality, logistics, agri-food, retail, healthcare, staffing and construction. The client list points to a focus on large groups and multi-site chains.

It is a weaker fit for small and mid-sized businesses with only a few roles, because prices are not public and the target group is high-volume. A reusable contact pool owned by the employer is not described as a core element in public descriptions.

Core features

• Social campaigns: job ads on Facebook, Instagram, Snapchat and TikTok with targeted delivery.
• Automation: according to the press release, recurring recruiting tasks in high-volume hiring are automated.
• ATS connection: applications are handed to the client's applicant tracking system.
• Recruiter platform: a tool for handling applicants day to day, alongside employer branding elements according to industry profiles.
• Provider-reported metrics: the acquisition announcement cites a 65% reduction in time-to-fill and a 50% decrease in candidate processing. These figures are self-reported and not independently verified.

Pricing

Seiza does not publish prices. Based on public information, as of October 2026, pricing is individual and depends on scope and budget, which is common for enterprise providers. Buyers who want to compare need to request a quote and clarify how media budget, platform fee and any service fees are combined.

Reviews

There are no reliable review figures on the main review portals that could be cited here. An independent assessment therefore relies mostly on industry profiles, the acquisition press release and the client list. Anyone evaluating Seiza should ask for references in their own segment.

Strengths

• Long track record since 2010 and large enterprise clients.
• Multiple channels, including Snapchat and TikTok alongside Meta.
• Part of the Adzuna group with its own job search engine, which may widen reach.
• Built for high-volume hiring with location logic.

Limitations

• No public prices; quotes on request only.
• Geared towards large accounts, probably oversized for small employers.
• Few independent reviews.
• After the Adzuna acquisition, product scope and pricing may change; current details should be requested directly.

For an assessment of Seiza, this means the platform is an established large provider, but the publicly verifiable information is limited to self-descriptions, press releases and industry profiles. Concrete cost per application, terms and contract conditions cannot be checked from the outside and have to be requested in a sales conversation. Treat all efficiency claims as hypotheses to test in a pilot, not as benchmarks.

What buyers should check with Seiza

With any social recruiting provider, a few points deserve a look before you sign, even though brochures rarely put them first. The following list applies to Seiza as much as to any alternative.

• Separate media budget from service fee: ask which share of your budget actually goes into Facebook and Instagram ads and which share stays with the provider.
• Ownership of contacts: clarify whether applicants land in your own company account or in the provider's platform, and whether you can take the data with you if you switch.
• Meta's Employment ad category: job ads face targeting restrictions, for example on age, gender and postal code. The provider should be able to explain how it handles them and state the current rules per region.
• GDPR and data processing: applicant data needs a data processing agreement, a clear statement on storage location and retention periods.
• Measurement: ask for metrics per role, namely cost per application, share of qualified applicants and time to first conversation, and ask for references from your industry.
• Term and cancellation: check minimum terms, notice periods and what happens to running campaigns.

Applicants from social media ads are often not actively job hunting and respond best to a short mobile application and a quick reply. How well a provider supports this flow shows less in the ad creative than in the time to the first response. With Seiza, ask in addition about the product roadmap after the Adzuna acquisition, data handling and the pricing model for your company size.

Alternatives

Comparable social recruiting providers are Wonderkind, Boostpoint, TalentBait, HeyJobs, Talentsconnect and jobtastic. Teams that want to pay for reach once and keep applicants in their own talent pool can look at tools with an employer-owned pool.
