## The use case: how 2X Solutions deploys Cartesia

2X Solutions runs voice AI agents that handle high-volume outbound and inbound customer calls, including qualifying and booking. It uses Cartesia's streaming text-to-speech and voice cloning for low-latency, natural-sounding voices that keep outbound calls within TCPA compliance limits.

Summary written by usedby from the source page, in English. The figures are those of Cartesia and 2X Solutions, not ours.

> With Cartesia, latency dropped to sub-100ms and the abandoned call rate was slashed from 3.4% to under 1.25%. Cartesia’s low-latency streaming delivers audio the moment a recipient answers, keeping 2X’s platform well within the two-second window at scale

- **sub-100ms**: “Latency reduced from 500-900ms to sub-100ms — providing substantial headroom within the two-second TCPA compliance window”
- **3-5%**: “The result: a 3-5% lift in callback rates across their customer base compared to generic voicemails.”
- **7-15%**: “Combined with a pre-call texting strategy that alerts prospects 3-5 minutes before the call, 2X sees a 7-15% increase in connected calls overall.”
- **10%**: “2X handles approximately 130,000 calls per day — nearly 3 million per month — and is growing at 10% monthly.”

> When we switched to Cartesia, we were below the TCPA 3% fairly substantially — we were at like one and a quarter percent.
