Knows where every patient is,
and what's blocking them.

Calvin runs the operational work between a referral arriving and a claim being paid. Work reaches your clinic by fax, portal and phone. Calvin turns each piece into a task carrying an owner, a clock, a blocker and the evidence behind it, acts on it across your systems and the payer's, and escalates to a person when it should.

For clinic owners and multi-site groups where a referral takes weeks to become a visit, and paperwork decides whether you get paid.

The problem

Denials start with paperwork done before the visit.

Front-end work produces denials at clinics of every size. In a 2026 survey of more than 400 revenue-cycle leaders, four in five traced denials to at least one front-end workflow. They named three drivers. Eligibility and benefits verification, authorization and pre-certification, and patient registration and demographic verification.

Registration and identity

Packets arrive by fax, portal and phone with records missing, ten handoffs between arrival and a booked appointment, and the same patient carrying two chart numbers.

Eligibility and benefits

A check gets run, then run again by someone who cannot see the first. What is missed before the visit returns ninety days later as a denial.

Authorization and pre-certification

The authorization lives in one system and the referral that produced it in another. Nobody can list which expire in two weeks with visits already booked.

Inovalon, 2026. Kodiak Solutions put 2025 net revenue lost to final denials and bad debt at $48 billion, up 25%. Identity alone drives 35% of denied claims, $6.7 billion system-wide.

What we found

Twelve weeks inside one specialty group found $3.1M a year of revenue leaking through three workflows.

$3.1M
Where it goes today. Only 53% of referrals convert to a booked appointment, at a median of 33 days. 40% of specialty fills capture contracted margin. Around 80% of their verification-driven aged AR traces to a check that could have been completed before the visit.
Measured against their own referral log, claims and remittance data rather than a benchmark. These are the gaps we are building Calvin to close, and to enable top-line growth and value recovery, with our first design partner.

Who we are

Calvin is spun out of Leapfrogger Labs.

Founded early 2025 as a bridge between frontier AI and regulated industries. We make what works in frontier labs run inside organizations with auditors, legacy systems and compliance officers.

Kishore Bhatia

Built early stage tech startups to scale. 3x CTO and founder, Fortune 500 and corporate ventures, with platform leadership across healthtech, digital identity and fintech at BCG Digital Ventures, Affinidi, CloudBees, BlockApps and JPMC.

We are looking for a small number of US clinics to work with this year.

Best fit: US specialty clinics and MSOs with three or more sites, real referral or prior-authorization volume, and an operational leader accountable for the workflow.

Design partner program

We measure what one workflow costs you, then test what Calvin can take off your team.

We pick one workflow with you, measure what it costs today, deploy alongside your team, and run a controlled pilot against that baseline. You end with a number you own and can act on. Your team works alongside ours from mapping through pilot.

Book a thirty-minute call

What you get

  • A baseline of what the workflow costs you today in time, delay and denied revenue, measured against your own data.
  • One forward-deployed engineer working alongside your operations team for the whole engagement.
  • Implementation support across workflow mapping, configuration, testing, deployment and issue resolution.
  • A controlled pilot with human approval on every action. Nothing reaches a payer without a person releasing it, and nothing runs unattended without acceptance criteria you agreed.
  • We report outcomes against that baseline, with definitions and denominators agreed in advance.
  • Early influence over what we build, and discounted production pricing if you continue past the engagement.

What we need from you

  • An executive sponsor, ideally a CEO, CFO, COO or equivalent operating leader.
  • A named operational owner who coordinates the engagement, makes workflow decisions, and joins mapping sessions, testing and weekly reviews.
  • Access to the staff who do the work across operations, revenue cycle, referral, benefits and chart preparation.
  • Access to the systems and data the workflow depends on, after the security and privacy review, inside permissions you set.
  • Time with your team to measure the current process before the pilot begins.
  • Candid feedback on what works, what fails and what production adoption would require.
How the engagement works

The engagement runs in six steps.

01
Pick one workflow, Appointment Readiness or Benefit Determination and Coverage Monitoring, then define its scope, users, systems and success measures.
02
Map the current state, with every handoff, exception, delay and hour of human effort.
03
Set the baseline before anything changes.
04
Configure and test with the forward-deployed engineer, connecting systems and running representative cases.
05
Run a controlled pilot with human-reviewed actions, clear escalation paths and agreed safety boundaries.
06
Decide together on operational impact, workflow fit, implementation effort and readiness for production.

Before anything connects we sign a BAA and complete your security review. Security and data handling.

Security and data handling

How Calvin handles
your clinic's data.

Last updated September 2026

Business associate agreement

Calvin operates as a business associate under HIPAA. We sign a BAA with your organization before any system connects and before any protected health information moves.

Our standard agreement covers permitted uses and disclosures, required safeguards, subcontractor obligations, breach notification without unreasonable delay and inside the period HIPAA requires, and return or destruction of PHI when the engagement ends. Ask and we will send the current version before your first call.

What Calvin holds

Operational state. Referrals, coverage and eligibility checks, authorizations, appointment readiness, work items, and the source documents those are derived from.

The medical record stays in your EHR. Calvin links to it rather than copying it, and never writes clinically to it.

What we will not do

Your patient data never trains anything outside your clinic. What crosses a clinic boundary is patterns and rules, meaning payer behavior, document structures and workflow configuration. PHI never does.

We do not sell, share or license your data, and we do not use it for any purpose outside the services in the agreement.

Where it runs

US-based cloud infrastructure. Data is encrypted in transit and at rest. Each clinic's data is logically isolated from every other clinic's.

We maintain a current list of subprocessors that may process PHI and share it on request. We give notice before adding one.

Access and audit

Named accounts and least privilege for anyone with production access, with multi-factor authentication on the near-term roadmap. Agents act through the same permissions as a person.

Every action leaves an audit record naming who acted, what changed, which rule they followed and what the system looked at. You can query it.

Human control

Nothing reaches a payer without a person releasing it. Nothing runs unattended without acceptance criteria you agreed in writing. Medical necessity is decided by your clinicians, permanently.

Certifications

We do not hold SOC 2 Type II today. We are building to the control set now and will publish the report date here when we have it. We can complete your security questionnaire and vendor review in the meantime if needed to comply with your requirements.

If the engagement ends

You get your operational data back in a documented export format. We return or destroy PHI as the BAA requires, and confirm it in writing.

Contact

Security questions, questionnaires and BAA requests go to security@leapfrogger.ai. We answer within two business days.

Questions before you connect anything?

Bring your security lead to the first call. We would rather clear the review early than discover it at the end.
