Zara vs Presto Voice

Presto Voice is a single-purpose operational tool: it answers the speaker post, takes orders, upsells add-ons and specials, and keeps the lane open 24/7. The differentiating pieces are the managed install (Presto says it can deploy at scale without disrupting live drive-thrus), the 'spectrum of voice AI approaches' positioning rather than one model, and ROI reporting on non-intervention, upsell offer rate, and revenue lift. The Toast integration announced Sept. 21, 2026 gives mutual QSR customers a documented order-data path. Presto's own benchmarks — up to 95% non-intervention, up to 88% upsell offer rate, up to 6% monthly incremental revenue — are vendor figures to validate in a pilot.

Zara is a hiring-evaluation product from micro1: it scores candidates on a representative work task instead of resume keywords, with expert human validation of the AI output and a human in the loop before offers. It adds bias/fairness analysis, customizable recruitment workflows, and hiring analytics, and is positioned on the same infrastructure as micro1's Realm and Cortex. Its credibility rests on published benchmarks (LegalReasonBench for long-horizon legal reasoning, CortexRetrievalBench for retrieval ranking, PersonalAgentBench for personal agents) rather than on a documented work-sample product you can deploy this quarter — the description itself points to CodeSignal as the shorter path for that. The two products share zero functional surface.

Both list pricing as 'contact', so there is no sticker number to compare. That's where the similarity ends.

Presto Voice is priced as a managed deployment: you're buying installation, POS/headset integration work, and ongoing vendor support for the speaker post, not a per-seat license. The economics are only legible against your own baseline — Presto publishes up to 6% monthly incremental revenue and up to 88% upsell offer rate as the intended payback levers, so the real cost test is a pilot comparing your current lane throughput, average order value, and headcount against post-deployment numbers. Single-location operators whose volume won't justify a managed rollout are explicitly out of scope, which tells you the deal size starts above that.

Zara is also quote-based, but it's sold into a hiring stack. Its own not-for list is the most useful pricing signal: low-volume hiring where a bespoke evaluation build never pays back, and any buyer who can't supply a domain expert to author the scoring rubric. That means the effective cost includes internal expert time on top of the contract. Companies already buying micro1 Realm or Cortex are the intended buyers, since Zara is a layer on the same stack. On either product, ask for a pilot scope and a written definition of the success metric before signing.
