Sinch is messagingassembledWe're one platform from day one.
Sinch is a global messaging powerhouse stitched together from acquisitions — Wavy (2020, LATAM), Inteliquent (2021, $1.14B for US voice), CLX heritage, and Sinch Engage on top. Twiching is one Singapore-founded platform with voice, messaging, AI and contact-centre on the same console.
The architecture difference
7 products on Sinch is one product on Twiching.
The same capabilities exist on both sides. The difference is how many things you integrate, monitor and reason about to get them to work together.

What ships in the box
Four things Sinch doesn't include.
Capabilities most teams burn a quarter rebuilding on Sinch — already part of Twiching the moment your account is provisioned.
Day-one parity, by default.
Every paid Twiching plan opens with the four items on the right pre-wired.
One platform, one product family
PlatformTwiching is one Singapore-founded platform. Sinch's voice (Inteliquent), messaging (CLX heritage + Wavy) and engagement tooling (Sinch Engage) live across stacks bolted together over years.
AI receptionist as a packaged preset
AITwiching ships a deployable AI receptionist on every paid plan with tiered free monthly minutes. Sinch's surface is mostly messaging APIs — no equivalent packaged voice-agent product.
Contact-centre on the same console
CCaaSQueues, supervisor tools, dialers and the omnichannel inbox sit in the platform. Sinch routes messages but doesn't ship an agent app for the contact centre.
Compliance baseline
TrustSTIR/SHAKEN, SOC 2 Type II (Pro+), written 99.99% SLA. Sinch publishes a 99.95% SMS SLA on enterprise contracts.

Buyer-first honesty
We don't win every round. Here's the balance, both ways.
One platform from day one
Twiching wasn't assembled from acquisitions — voice, messaging, AI and CC share a data model.
AI receptionist as a packaged product
Sinch is messaging-first; it doesn't ship a turnkey AI voice receptionist.
Contact-centre on the same console
Twiching ships an agent app, queues and supervisor tools. Sinch routes traffic; the app layer is yours.
Written 99.99% / 99.999% SLA
Twiching commits 99.99% on the platform and 99.999% on SIP termination. Sinch publishes 99.95% on SMS.
Singapore-anchored APAC presence
Founded in Singapore (2019). Sinch is Stockholm-headquartered with global presence.
RCS Business Messaging maturity
Sinch is one of the most credible RCS providers globally — particularly for rich-media campaigns.
Global SMS scale
Carrier relationships across LATAM (Wavy), US (Inteliquent) and EMEA (CLX) at hyperscale volumes.
Multi-channel Conversation API
Unified API across SMS, RCS, WhatsApp, Messenger and Viber for engineering-led messaging programs.
Mature enterprise messaging product
Decades of carrier-grade messaging engineering and an established compliance posture.
