Introduction
Infinitus Systems is a San Francisco digital health company founded in 2019 that builds voice artificial intelligence agents to automate phone-based healthcare administrative workflows — benefit verification, prior authorization follow-ups, and payer coordination calls that otherwise consume hours of human staff time per patient. Shyam Rajagopalan co-founded Infinitus and serves as founder and technology lead; Ankit Jain co-founded the company and serves as founder and company lead per Infinitus’s about page reviewed in July 2026.
Infinitus frames its mission around patients who need care most but fall through gaps created by phone hold times, payer call center delays, and specialty pharmacy staff stretched across repetitive administrative tasks. Voice AI here is not a consumer chatbot — it is operational infrastructure for organizations that must complete thousands of outbound and inbound payer calls to unlock treatment access.
What the company does
Infinitus deploys AI voice agents trained for healthcare phone conversations — navigating payer IVR systems, confirming coverage details, checking prior authorization status, and documenting call outcomes in structured formats operations teams can act on. The platform targets workflows where human callers repeat the same script hundreds of times daily, freeing clinical and patient services staff to handle exceptions requiring judgment rather than dial-tone labor.
Unlike general-purpose conversational AI adapted for healthcare, Infinitus emphasizes domain-specific speech models and call-flow logic tuned for payer terminology, HIPAA constraints, and the failure modes of live phone systems — dropped calls, incorrect transfers, and ambiguous benefit language that generic voice bots mishandle.
Infinitus integrates call results into customer operations dashboards so pharmacy hubs, health plans, and pharmaceutical hub services track which patients cleared administrative barriers and which require human escalation — closing the loop between automated calls and care delivery teams.
Who it serves
Infinitus serves specialty pharmacy operations, pharmaceutical patient support programs, health plans, and provider organizations where phone-based payer interactions gate treatment starts. Customers typically measure success by call completion rates, time-to-therapy initiation, and staff hours redirected from repetitive dialing to complex case management.
Organizations with high-cost specialty medications — where a delayed benefit verification directly postpones infusion or injection starts — represent Infinitus’s core buyer profile. Patient services leaders evaluate voice AI on payer coverage breadth and call success rates across major commercial and government plans, not demo conversation quality alone.
Company background
Rajagopalan and Jain founded Infinitus in 2019 in San Francisco, combining Rajagopalan’s technology leadership with Jain’s company-building focus to address phone workflow automation in healthcare — a problem space largely untouched by EHR-embedded AI vendors focused on documentation and imaging. The company raised venture funding and expanded enterprise deployments as prior authorization volume grew industry-wide.
Infinitus’s dual-founder structure — technology lead and company lead — reflects the operational reality that voice AI products require both speech engineering depth and healthcare go-to-market expertise selling into pharmacy and payer operations rather than hospital CIOs alone.
Product and AI capabilities
Infinitus voice agents apply speech recognition, natural language understanding, and call orchestration to navigate live phone systems — a harder engineering problem than text chat because agents must handle hold music, accents, partial information, and payer representative variability. The company’s workforce transformation materials describe AI augmenting healthcare staff by absorbing high-volume call tasks while humans retain oversight for clinical and contractual edge cases.
Call audit trails and structured outcome logging support compliance reviews — essential when automated agents act on behalf of covered entities handling protected health information during payer conversations.
Key developments
2019: Infinitus Systems founded in San Francisco by Shyam Rajagopalan and Ankit Jain. 2025–2026: Infinitus published resources on AI transforming the healthcare workforce via automated phone workflows (infinitus.ai resources, official source). 2026: Infinitus continued enterprise voice AI deployments for specialty pharmacy and payer operations customers.
Infinitus’s official workforce resource page frames the patients who need care most as those falling through administrative phone gaps — messaging consistent with the company’s specialty pharmacy and patient access GTM focus.
Why it matters
Infinitus matters because prior authorization and benefit verification phone work is among the largest hidden labor costs in U.S. healthcare — and most 2026 clinical AI investment flows to documentation and imaging instead. Voice agents that reliably complete payer calls can accelerate time-to-therapy for specialty patients where every delayed day affects outcomes and manufacturer program metrics.
Infinitus complements EHR automation vendors such as Notable Health and clinical documentation platforms — Notable automates digital intake while Infinitus automates the phone calls that still gate authorization after digital forms submit. Health systems and pharma services teams should map both workflow types when measuring access friction.
Sector context
Infinitus belongs in Brel’s AI in healthcare coverage under digital health and administrative automation, related to patient access platforms like Notable and revenue integrity tools like SmarterDx but focused on voice phone workflows rather than EHR documentation or claims appeals. Buyers should evaluate payer coverage maps and call success benchmarks before enterprise rollout.
Specialty pharmacy leaders comparing voice AI vendors should require live payer IVR navigation demos — not scripted sandbox calls — because real-world hold times and transfer logic determine automation ROI.
