SleekFlow AgentFlow

SleekFlow is an omnichannel conversational commerce company launched in 2019 that operates in Hong Kong, Singapore, Malaysia, Indonesia, Brazil and the UAE. It helps brands sell and support customers over WhatsApp, Instagram, Messenger, LINE, WeChat, TikTok, SMS and email from one platform.

AgentFlow, launched in July 2025, adds teams of specialised AI agents built on a multi-agent architecture with a graph database and vector-based retrieval. Agents trained on a company's website and documents can recommend products, book appointments, score leads and resolve tickets, connecting to Shopify and CRMs without code, while a data analyst agent turns conversations into insights. It runs alongside the team inbox, broadcast campaigns, flow builder and payment links used by retail, beauty, education and hospitality brands.

• Multi-agent AI: specialised agents for retrieval, inquiry resolution and lead scoring.
• Knowledge training: learns from websites, spreadsheets, PDFs and visual documents.
• Model selection: uses GPT-4o, GPT-4o-mini and Gemini per task on Azure OpenAI.
• Omnichannel inbox: WhatsApp, Instagram, Messenger, LINE, WeChat, TikTok, SMS and email.
• Automation and campaigns: flow builder, broadcast campaigns, catalogue and payment links.
• Integrations: Shopify, HubSpot, Salesforce, VTEX and Google Sheets.

Beauty clinics and spas in Vietnam can let AI agents book appointments and answer service questions on messaging apps. Fashion and cosmetics retailers can recommend products and send payment links in chat. Language centres can qualify enrolment leads before counsellors call.

Answers product and booking questions on messaging apps around the clock and hands qualified leads to sales staff. Keeps all channels and AI agents in one inbox so teams see full conversation history. The site cites customer results such as 6x conversions at Medilase and 21% more orders at Wear That. Training from existing documents requires no code.

Conversational commerce on messaging apps is a major sales channel across Southeast Asia, and businesses now add AI agents to handle volume outside working hours. Vietnamese retailers, clinics and education providers that sell through chat face the same need to automate replies while keeping a human handover.

SleekFlow has served businesses since 2019 and is led by CEO Henson Tsai. It has raised USD 23.5 million in total, including an additional Series A+ round in June 2025, from Atinum Investment, AEF Greater Bay Area Fund, Moses Tsang and Mars Growth Capital. It is a Meta Business Partner and states ISO/IEC 27001, SOC 2 Type II and GDPR compliance.
