VoiceOS

What do they actually do

VoiceOS sells an enterprise SaaS that automates first‑round candidate screening by running voice‑based interviews. Hiring teams connect their ATS, set up interview scripts or decision trees, and VoiceOS automatically schedules and conducts phone interviews with applicants. The platform records audio, generates transcripts, analyzes responses, and surfaces pass/fail signals and analytics so recruiters can review results instead of doing manual phone screens voiceos.com.

Today the company is focused on recruiting teams at mid‑to‑enterprise companies and is running enterprise pilots, including with a Fortune 500 customer, indicating the product has moved beyond prototype into trials with large buyers YC launch post. Near‑term work is about deepening ATS/HR integrations and improving screening quality with analytics and optimization features tied to hiring outcomes voiceos.com.

Who are their target customer(s)

• Enterprise talent‑acquisition leaders at large companies: They face high application volumes and inconsistent manual phone screens that are slow and hard to audit; they want a scalable, repeatable prescreen that plugs into existing ATS workflows YC launch post voiceos.com.
• High‑volume frontline hiring managers (retail, call centers, distribution): They must staff quickly but run into scheduling bottlenecks and high per‑hire screening costs; they need fast, predictable triage that reduces human time on first‑round screens YC launch post voiceos.com.
• Recruiting operations and ATS administrators at mid‑to‑large firms: Fragmented workflows and manual scheduling slow teams down; they want an ATS‑integrated screening tool that automates scheduling and produces transcripts and reports voiceos.com.
• Recruiters and sourcers at mid‑market companies: Back‑and‑forth scheduling and first‑round phone screens reduce hiring velocity; they need an automated prescreen that surfaces qualified candidates with reviewable transcripts voiceos.com.

How would they acquire their first 10, 50, and 100 customers

• First 10: Convert existing pilots and enterprise prospects into paid contracts, starting with the Fortune 500 pilot, and run tightly scoped 30–60 day pilots for 9 more TA leaders sourced via inbound demos and founder/YC introductions, anchored on one ROI metric (time saved per screen or screens/hour) YC launch post voiceos.com.
• First 50: Systematize the pilot playbook for frontline verticals (retail, call centers, distribution), hire 1–2 enterprise reps and an implementation engineer, and drive conversions through ATS integrations/marketplace listings plus a referral incentive for early customers voiceos.com.
• First 100: Formalize ATS partnerships and co‑sell agreements and launch a productized self‑serve pilot for mid‑market to reduce sales touches; expand within accounts via standardized scorecards, compliance controls, and A/B‑testing insights.

What is the rough total addressable market

Top-down context:

The broader talent‑acquisition software market is about USD 10.8B in 2024; within it, ATS is roughly USD 2.7B and interview scheduling/automation is about USD 2.1B, per analyst estimates GMI Insights Market Research Future.

Bottom-up calculation:

VoiceOS competes in the screening/interviewing automation slice, which reasonably sits around USD 2–4B today by triangulating interview scheduling (~USD 2.1B) plus adjacent ATS screening modules and video/voice interviewing, adjusted for overlap GMI Insights Market Research Future.

Assumptions:

• Large enterprises already run ATS platforms, so integrated screening budgets are accessible Jobscan.
• Overlap exists between ATS, scheduling, and interviewing tools, so segment sizes are not simply additive.
• Adoption of AI/automation in interviewing is growing, supporting sustained spend in this slice.
