A unified messaging API (SMS/WhatsApp/RCS) built for AI-native products, now a licensed US carrier
Last verified August 17, 2026 · Updated daily
What Sent is building
Sent is a single API that lets a company reach any user over SMS, WhatsApp, or RCS through one integration. Its platform automatically routes each message to the channel most likely to deliver — handling content formatting, carrier complexity, and compliance across 75+ carrier integrations. The bet: as AI agents start sending more messages than humans ('agentic messaging'), the legacy A2P messaging stack isn't built for it. Per Sent's own release, 'the global A2P messaging market is worth approximately $100 billion and dominated by legacy vendors like Twilio, Sinch and Infobip,' which it argues are 'unprepared for the wave of agentic messaging.' Crucially, Sent became an FCC-licensed telecom carrier, moving from a software layer on top of carriers to owning the infrastructure — which its investors call real distance from the incumbents.
Why this matters
Companyon has led every round in Sent's history and is 'tripling down,' with Bessemer and UIF following on — a strong repeat-investor conviction signal at Series A. The FCC carrier license is the differentiator: most 'better Twilio' pitches never get regulatory standing. The idea came to CEO Daniel Vataj in 2023 when his bank's SMS authentication code failed while he traveled abroad.

How to actually get hired at Sent
Why applying the normal way doesn't work
There's an ATS, but at Sent, referrals get priority. Your cold application competes with sourced candidates and internal recommendations.
Who to contact at Sent
What to show them
Show low-level messaging/telecom experience — SMPP, carrier integrations, SMS/RCS/WhatsApp Business API, deliverability optimization, or building high-throughput routing systems. Having worked at a CPaaS (Twilio, Sinch, Bandwidth) or on carrier-grade infra is gold.
A cold email that works at Sent
What Sent screens for
Referencing the move from software vendor to licensed carrier, and understanding RCS and cross-carrier deliverability/compliance, shows you did real homework. Knowing the engineering team is in Albania (co-founder Betim Drenica's base) signals you looked past the press release.
A tailored CV beats a generic one. Use Sent's job description language to clear filters.
Don't make these mistakes
Don't pitch Sent as 'just another Twilio wrapper' — the FCC carrier license and direct carrier relationships are the whole point; showing you understand A2P/telecom regulation and deliverability beats a generic API-integration resume. Don't ignore the 'agentic messaging' thesis.
Mistakes that kill Sent applications
A recycled CV gets rejected fast at Sent ( people). They notice.
Don't open with what you want. Open with what Sent is dealing with right now — Companyon has led every round in Sent's history and is 'tripling down,' with Bessemer and UIF following on — a strong repeat-investor conviction signal at Series A, and what you'd do about it.
The wait-and-hope strategy fails. Follow up on day five — response rates roughly double.
