What Graybox does

Graybox (주식회사 그레이박스) is a privately-held Korean software company headquartered in the Gangnam district of Seoul that builds and operates Notifly, a CRM marketing automation platform targeting small and medium-sized online businesses in South Korea. The company was founded in 2023, operates with a 1–10 person team, and is venture-backed, having closed a Pre-Series A financing round in May 2025. Its sole commercial product, Notifly, is positioned as a single-pane engagement platform that unifies multi-channel customer messaging — primarily KakaoTalk (including Kakao Brand Messages) and app push notifications — with real-time, behavior- and journey-based targeting, allowing customers to run CRM campaigns without dedicated marketing personnel.

Technically, Notifly is a cloud-based SaaS platform whose core capabilities center on ingesting user behavior events, segmenting users by journey state, and orchestrating outbound messages across channels from one interface. Differentiated features include real-time behavior-based targeting, a multi-channel messaging hub spanning KakaoTalk and mobile push, and direct sending of Kakao Brand Messages through a partnership-level integration. The platform is also the first Korean marketing automation solution listed on Naver Commerce Solution Market (added December 2024) and integrates with Mixpanel (official partnership announced January 2026) for behavior data flowing into messaging execution. Operating metrics reported by the company as of January 2026 include approximately 143 customer companies, 1.4 billion cumulative messages sent, and 4.6 million average daily messages.

Commercially, Graybox operates a SaaS subscription model with no publicly disclosed pricing; go-to-market combines a product-led growth / self-serve motion through notifly.tech for SMBs, a marketplace listing on Naver Commerce Solution Market, and an emerging enterprise field-sales motion evidenced by an open Business Development Manager role targeting conversion of accounts currently on global CRM solutions. Customer segmentation is horizontal and primarily SMB-focused, with a secondary enterprise segment being actively developed; the only publicly named enterprise reference is OHouse (오늘의집), an e-commerce / home-living platform that deployed Notifly for experimentation and CRM messaging improvements in 2024. The company is single-country (South Korea) with no disclosed geographic expansion plans.

Regional players

• Sendbird: Korean-founded in-app messaging and customer engagement platform with global reach, providing chat, push, and notifications APIs. Comparable channel coverage and Korean-origin DNA to Notifly, though primarily serving enterprise/developer use cases globally.

Others

• Toss (Viva Republica): Korean super-app with its own messaging and notification infrastructure reaching a large user base. Relevant ecosystem comparator in the Korean messaging and consumer-engagement landscape, though primarily a consumer fintech rather than a B2B CRM automation vendor.

Broad incumbents

• Braze: Global cross-channel marketing automation and customer engagement platform supporting email, push, SMS, and in-app messaging. Closely comparable product category to Notifly, but at global enterprise scale with broader channel coverage and deeper analytics.
• Salesforce Marketing Cloud: Enterprise marketing automation, email, mobile messaging, and journey orchestration suite from Salesforce. Notifly explicitly positions against this category for enterprise conversion in Korea, making it the primary incumbent competitor.
• Iterable: Multi-channel customer communication platform for push, email, SMS, and in-app messaging used by mid-market and enterprise brands. Comparable to Notifly's unified messaging hub value proposition, but with a US/global customer base and broader feature set.
• Adobe Marketo Engage: Enterprise B2B/B2C marketing automation and lead management platform from Adobe. Comparable at the automation/workflow level, though Notifly targets a much smaller, Korea-centric customer base.

Direct peers

• Customer.io: Behavior-based messaging automation platform for SaaS and digital businesses, enabling event-triggered email, push, SMS, and in-app messaging. Highly comparable to Notifly's real-time user behavior and journey-based targeting model, serving a similar SMB-to-mid-market segment.
• Channel Corporation (Channel Talk): Korean customer engagement and messaging platform offering chat, CRM, and marketing automation for online businesses. Most directly comparable Korean peer to Notifly, competing for the same SMB e-commerce and online service customers.
• IGAWorks: Korean mobile marketing and analytics platform providing attribution, push messaging, and user engagement tools. Comparable to Notifly on the mobile push and user behavior targeting side, with a stronger attribution/analytics heritage.
• Airship: Mobile-first customer engagement platform specializing in app push, in-app messaging, and journey orchestration. Directly comparable to Notifly's app push and multi-channel messaging capabilities for digital-first brands.
