What Slido does

Slido is a Bratislava-headquartered audience interaction platform founded in 2012 that enables live polls, Q&A, quizzes, word clouds, and surveys for meetings and events. Participants join via a link or QR code from any browser without downloads or logins, and hosts can embed Slido natively inside PowerPoint (Windows and macOS), Google Slides, Cisco Webex, Microsoft Teams, and Zoom. The platform supports up to 5,000 participants per session on the Enterprise tier and up to 20,000 on Large Enterprise custom plans, with organization-level analytics, engagement scoring, and Q&A sentiment analysis. Slido is a wholly-owned subsidiary of Cisco Systems (acquired in 2021) and operates as part of the Webex portfolio while retaining its standalone product identity.

The company operates a freemium product-led growth motion layered with an enterprise field sales motion. A free Basic tier is offered with no credit card required, and paid annual tiers are priced at US$210/yr (Engage), US$900/yr (Professional), and US$2,400/yr (Enterprise), plus per-seat member add-ons, an Education tier starting at US$7/month, and one-time event plans from US$60. Enterprise customers receive SSO, SCIM provisioning, Theta Lake compliance integration with EU data residency, HIPAA/BAA support, Spaces, organization analytics, and a dedicated Success Manager. The customer base spans 750K+ organizations including 71% of Fortune 500 companies, with named users across Cisco, Oracle, Booking.com, MongoDB, WebSummit, Continental, Suntory, TomTom, Zapier, Transport for London, the Toronto Transit Commission, and UC Berkeley.

Slido's product surface is increasingly augmented by an in-product AI layer branded 'Slido AI,' which provides generative poll and quiz creation from prompts or slide content, an AI writing assistant for refining poll wording, a Question AI helper for participants, and Q&A sentiment analysis. The platform is available in 32 participant-interface languages, holds ISO 27001, ISO 9001, SOC 2 Type 2, GDPR, and HIPAA certifications, and has earned G2 Leader, Best Usability, and Most Implementable recognition for Winter 2026.

Expansion highlights3 records

Direct peers

• Poll Everywhere: Poll Everywhere provides live audience polling and Q&A integrated into PowerPoint, Google Slides, and Keynote — overlapping directly with Slido's core product positioning, presentation integrations, and education/enterprise use cases.
• AhaSlides: AhaSlides offers interactive polls, quizzes, word clouds, and Q&A for presentations and events. It is a direct competitor in the audience engagement category, especially for teachers, trainers, and event organizers.
• Glisser: Glisser provides live Q&A, polling, and audience engagement tools for conferences and corporate events. It competes directly with Slido in the events and large-meeting segment.
• Vevox: Vevox is an audience interaction platform focused on live polling, Q&A, and surveys for meetings, events, and higher education — a direct competitor in the same category with strong education and enterprise traction.
• Mentimeter: Mentimeter is a direct competitor offering live polls, quizzes, word clouds, and Q&A for meetings, presentations, and events. It targets the same enterprise, education, and event-organizer buyers with a comparable freemium-to-Enterprise SaaS model.

Broad incumbents

• Kahoot!: Kahoot! is a broader learning and engagement platform with live quizzes, polls, and interactive presentations used heavily in education and corporate training — overlapping with Slido's quiz and education use cases but with a much wider learning ecosystem.
• Zoom: Zoom offers native polling, Q&A, and AI Companion features directly within Zoom Meetings and Webinars. As both a Slido integration partner and a free substitute for basic use cases, it is a broad incumbent shaping Slido's competitive landscape.
• Microsoft Teams: Microsoft Teams includes native Forms-based polls and Q&A in meetings and has its own AI features (Copilot). As a major Slido integration partner and a free substitute, Teams represents a broad incumbent whose platform decisions materially affect Slido's reach.

Emerging players

• Quizizz: Quizizz is an interactive learning platform with live quizzes, polls, and lessons primarily for K-12 and increasingly for corporate training — overlapping with Slido's Education solution in formative assessment and live quizzes.

Others

• Cisco Webex: Cisco Webex is both Slido's parent platform and an integration channel. While Webex has native polling, Slido's 'most powerful integration' status makes Webex a deeply intertwined counterpart rather than a pure competitor, but its native capabilities are a strategic risk factor.
