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, plus a roleplay that practices a single objection seeded from one of the rep's own recorded calls. That roleplay is a step inside the recording workflow, not a standalone practice product, and it cannot run until your team has recorded real appointments.
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 built from your business who objects like the real thing, with an optional live coach during practice and a score on every call. 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 deals because they are not ready, more visibility into the losses does not fix it. ColdOpen builds the readiness first, shows managers who has it, records nobody, and starts with 10 free minutes.

Yes, a limited one. Siro's site describes a roleplay that practices a single objection using context from one of the rep's own recorded calls, tucked into its Prepare step, per its site in August 2026. It needs a recorded call to seed it, so it only activates after your team records real appointments, and the product still leads on recording and Halftime live in-call coaching. ColdOpen is practice-first: full voice roleplay against four buyers, each pushing back in its own way, with an optional live coach, before any real 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 or more per user per year) plus setup. ColdOpen publishes its prices: Team is $249 a month ($2,988 a year) for 1,400 minutes the whole team shares, Solo is $29 a month, and every account starts with 10 free minutes. Confirm current Siro pricing with Siro.
