What Sent does
Sent, Inc. is a unified messaging infrastructure company founded in December 2023 by Daniel Vataj (CEO) and Betim Drenica (CTO) and headquartered in New York. The company operates a single API that abstracts SMS, WhatsApp, and RCS into one integration, with an intelligent routing engine that selects the optimal channel per recipient based on availability, cost, and deliverability, and automatically falls back to alternate channels when primary delivery fails. The platform handles compliance automation (10DLC brand and campaign registration, WhatsApp template approvals, opt-in/opt-out enforcement, GDPR) as a registered carrier with direct interconnects, and exposes unified templates that are transformed per channel at send time. SDKs are available in seven languages (TypeScript, Python, Java, C#, Go, PHP, Ruby), with a sandbox mode for testing and an MCP server for AI coding agents.
Sent monetizes through a usage-based pay-as-you-go model at $0.015 per contact per month with carrier fees passed through at cost, alongside an enterprise tier with custom volume pricing, SLAs, and dedicated support. A free tier (first 10,000 messages and 100 contacts, no credit card required) and self-serve onboarding make the platform developer-first, with enterprise sales layered on for high-volume senders. Target use cases span e-commerce (order/shipping notifications, cart recovery), SaaS (verification, account notifications), fintech (transactional and fraud alerts), healthcare (appointment reminders, patient notifications), and authentication/OTP. The company reports 14,000+ developers and product teams, 550M+ contacts reached, 99.9% uptime SLA, and $5.8M in total funding raised across backers including Andreessen Horowitz, Sequoia, Y Combinator, Bessemer Venture Partners, Companyon Ventures, Urban Innovation Fund, and CP Overture, with a $3.55M Series Seed closed in late 2025 / early 2026.

Sent competitors and assessment
Company assessmentBroad incumbents
- Twilio: Twilio is the dominant CPaaS platform offering SMS, WhatsApp, and voice APIs globally. While much larger and broader than Sent, Twilio's messaging API is the primary alternative for developers Sent targets, and Twilio's pricing and reliability set the benchmark Sent must beat.
- Vonage (Ericsson): Vonage, now part of Ericsson, provides the Vonage Communications API covering SMS, voice, video, and WhatsApp. As an established enterprise-focused CPaaS owned by a major telecom vendor, it is a broad incumbent competitor with deeper enterprise distribution than Sent.
- Sinch: Sinch is a global CPaaS leader offering messaging APIs including SMS and WhatsApp across 200+ countries. As a publicly-traded incumbent with significant carrier relationships, it competes with Sent in multi-channel messaging for enterprise and developer segments.
- Infobip: Infobip is a major CPaaS provider offering SMS, WhatsApp, RCS, and omnichannel messaging platforms. As a global incumbent with strong WhatsApp Business API presence and enterprise focus, it competes directly with Sent for multi-channel messaging customers.
Direct peers
- MessageBird (Bird): Bird (formerly MessageBird) provides multi-channel business messaging including SMS, WhatsApp, and other channels via API. As a direct CPaaS competitor with comparable developer-first positioning and WhatsApp Business API support, it is the closest head-to-head to Sent in the SMB/developer segment.
- Plivo: Plivo offers cloud communications APIs for SMS, voice, and WhatsApp with developer-friendly pricing. As a direct CPaaS competitor targeting developers and product teams with similar self-serve onboarding, it competes with Sent for the same technical buyer.
- Telnyx: Telnyx provides programmable communications including SMS, voice, and messaging APIs with a focus on private network infrastructure and competitive pricing. Its developer-first approach and direct carrier relationships parallel Sent's registered-carrier positioning.
- Bandwidth: Bandwidth provides communications APIs for messaging and voice with its own carrier network. As a CPaaS competitor with direct carrier relationships similar to Sent's registered-carrier status, it offers an alternative for enterprises seeking messaging infrastructure.
Emerging players
- Wati: Wati focuses on WhatsApp Business API for SMBs with a no-code/low-code platform. While more SMB-focused and WhatsApp-centric than Sent, it overlaps in the multi-channel business messaging space, particularly for smaller customers Sent's free tier also targets.
- Respond.io: Respond.io provides a multi-channel messaging platform supporting WhatsApp, SMS, and other channels with developer APIs. As an emerging player with comparable multi-channel positioning and developer focus, it represents an adjacent competitor in Sent's target market.
