What Stringee does
Stringee is a Communication Platform as a Service (CPaaS) provider founded in 2017 and headquartered in Hanoi, Vietnam, with additional offices in Ho Chi Minh City, Middletown (Delaware, US), and Mumbai (India). The company offers a unified suite of programmable communication APIs — Stringee Call API (voice/video calling), Stringee SMS API, Stringee Chat API, Stringee Video Conference API (beta), and Stringee Programmable Contact Center API — built on WebRTC, SIP, and cloud infrastructure, distributed to developers via SDKs for iOS, Android, JavaScript, React Native, and Flutter, plus GitHub sample repositories and a freemium self-serve console. Above the API layer, Stringee operates StringeeX (stringeex.com), a separate omnichannel contact-center SaaS product that consolidates voice, video, SMS, chat, email, Facebook, and Zalo into a single agent interface with intelligent call routing, queue management, recording, and an affiliate/reseller channel program. Its strategic focus on the Vietnamese market is reinforced by government recognition (Make in Vietnam, Top 10 Sao Khuê 2023, Nhân Tài Đất Việt 2018) and a roster of enterprise customers spanning telecom (Viettel, Mobifone), banking (TP Bank, VietinBank, NCB), securities (VNDirect, Mirae Asset), insurance (Hanwha Life), mobility (Be Group), and technology (FPT, Honda, Golden Gate, Dat Xanh).
Stringee's business model combines usage-based pricing (per-minute voice/video, per-message SMS, separate video-recording fee of $0.018/min) with tiered annual subscriptions (Free with 1,500 minutes and 4 concurrent calls, Standard at $660/yr, Growth at $3,432/yr, and a custom Enterprise tier for accounts exceeding 1M minutes/month) and enterprise multi-year contracts. Go-to-market is hybrid: product-led growth through the self-serve developer console with a 30-day free trial for SMBs and individual developers, paired with direct enterprise field sales and dedicated account managers for larger accounts in Vietnam, the US, and India. The company reports 1,000+ enterprise customers and between 55 million and 70 million end users across all client applications, processing 2.5 million call minutes per day. As of April 2023, Stringee had raised a $2 million Series A led by DAIWA-SSIAM Vietnam Growth Fund II, with prior participation from VinaCapital Ventures, Zone Startups Vietnam, and government support.
The company has 100+ personnel, more than half of whom are IT engineers, and operates under the legal entity Công Ty Cổ Phần Stringee (a Vietnamese joint-stock company). Its compliance posture is narrow: PCI-DSS obligations are delegated to third-party payment processors rather than held directly. The competitive set is dominated by global incumbents (Twilio, Vonage, MessageBird) and regional peers; Stringee's positioning leans on local-language support, government endorsement, regional telco economics, and a Vietnam-led go-to-market as it expands internationally.
