Siro records in-person sales conversations, analyzes them, and automates the CRM work afterward, and in 2026 added Halftime, live AI coaching during the call. As of July 2026 its site does not feature a roleplay or practice product.
So this is not a close call on what each one is for. Siro is built to observe the appointment. ColdOpen is built so the rep walks into it having already had that conversation ten times, against an AI buyer who objects like the real thing and scores them on it. Nothing real is captured, which also means there is nothing to disclose.

The bottom line
Siro is a capable set of eyes on appointments that have already happened. If reps are losing doors because they are not ready, more visibility into the losses does not fix it. ColdOpen builds the readiness first, records nobody, and starts free.

Not as far as we can tell. As of July 2026 Siro's own site leads on recording, transcription and Halftime live in-call coaching, and does not feature a roleplay or practice product. Confirm with Siro directly, since products change. ColdOpen is practice-first: full voice roleplay with difficulty dials, before any call happens.
Siro publishes no public pricing. Third-party guides estimate roughly $30,000 to $40,000 per year for a 10-person team (about $3,000+ per user) plus setup. ColdOpen uses pooled team minutes and starts free. Confirm current Siro pricing with Siro.
Yes. Recording in-person conversations is core to Siro, which publishes a recording-adoption guide. ColdOpen never records a customer, so there is no consent rollout.
Yes: ColdOpen. Reps practice out loud against an AI buyer and are scored against a rubric, and no real customer is ever recorded.
