About
Relay.app is a human-in-the-loop workflow automation platform founded in 2021 in San Francisco. The company was built around the insight that fully automated workflows break down at the edges — when decisions require human judgment, context that only a person has, or approval before an irreversible action. Relay.app's core design principle is that AI agents and humans should collaborate in workflows rather than the AI operating autonomously.\n\nThe platform connects to 100+ applications including Salesforce, HubSpot, Slack, Gmail, Notion, and Airtable, enabling teams to build complex cross-app automations with embedded human checkpoints — approval steps, form fills, and manual decisions that slot naturally into otherwise automated flows. Relay.app's AI agents can draft content, classify data, extract information from documents, and make routing decisions, with humans stepping in only where judgment is needed. Target users are operations, revenue, and customer success teams at mid-market B2B companies.\n\nRelay.app raised a $35 million Series A in March 2025 co-led by Andreessen Horowitz and Khosla Ventures, validating its human-in-the-loop positioning in a market increasingly crowded with fully autonomous automation tools. The funding has accelerated the expansion of its AI agent capabilities and integration library. Relay.app competes with Zapier, Make, and newer AI automation platforms but differentiates through its thoughtful balance between automation efficiency and human oversight.

About
Cvent is an enterprise event management software company founded in 1999 and headquartered in Tysons, Virginia, built to digitize and manage the full lifecycle of corporate meetings, conferences, trade shows, and incentive programs. The company was founded by Reggie Aggarwal after experiencing firsthand the operational chaos of planning corporate events with spreadsheets and phone calls. Cvent's mission is to give event professionals a comprehensive technology platform that manages every dimension of event execution — from venue sourcing and attendee registration to on-site check-in and post-event analytics — at enterprise scale.\n\nCvent's platform encompasses venue sourcing and RFP management through the Cvent Supplier Network, event registration and marketing, mobile event apps, on-site solutions, virtual and hybrid event capabilities, and attendee engagement tools. The company also operates one of the hospitality industry's most important data assets — a database of over 300,000 venue profiles used by meeting planners globally to source and evaluate event spaces. Cvent serves over 24,000 customers ranging from Fortune 500 event teams to professional conference organizers, and its platform sourced $16.5 billion in group business volume through its supplier network. Blackstone acquired Cvent in 2023 following its public market stint.\n\nCvent reported trailing twelve-month revenue of approximately $650 million as of October 2025 and holds approximately 35% market share in the global event management software category. Its combination of deep enterprise penetration, the industry-standard venue sourcing network, and post-pandemic demand for hybrid event capabilities reinforces its position as the dominant platform in corporate event management. Cvent's scale, switching costs, and Blackstone's growth capital create a formidable competitive position in a market undergoing digitization and consolidation.
