Crisphive

Built for pharmacy courier operators

Deterministic scheduling for pharmacy couriers, embedded in the software your drivers already use.

Crisphive sits behind your existing dispatch board, pharmacy system, or AI assistant. When a driver calls in sick at 6:30 or a STAT oncology delivery lands mid-route, it re-cascades cold-chain runs, controlled-substance drops and long-term-care rounds across qualified, nearby drivers in under 3 seconds — without missing a dose window, and without anyone learning a new tool.

Every job inside its window

The day Crisphive protects

  • Refrigerated pharmacy courier van backed up to a pharmacy loading door at dawn, insulated totes stacked on a hand truck

    The route

    40–80 drops a day per van across clinics, care homes and patients' doors. One absent driver is a day of missed doses.

  • Validated cold-chain cooler open on a van floor, gel packs and a temperature data logger showing a reading, sealed medication bags inside

    The cold chain

    Insulin, biologics and vaccines carry excursion limits. Every re-route must respect the time out of refrigeration.

  • Handheld signature device and a sealed tamper-evident pharmacy bag on a long-term-care nurses' station counter

    The chain of custody

    Controlled substances need a trained, background-checked driver and a signature. The solver treats that as a hard constraint, not a note.

The problem is statistical, not occasional

Every week, roughly 1 in 30 of your field crew won't show up as scheduled.

Across transportation and material-moving occupations, 3.4% of full-time workers miss part of any given week — and 1.8% of scheduled hours are simply lost. Illness and injury, not vacations, drive most of it.

  6. Construction industry overall2.3%

U.S. Bureau of Labor Statistics, Current Population Survey Table 47, 2025 annual averages (11-month average, excluding Oct 2025). Construction reads low partly because unpaid hourly absences go unrecorded.

Planning rule of thumb

1 absent tech per 30, every week

At a 2.7–3.4% weekly absence rate and 1.5–1.9% of hours lost, plan for about one absent technician per 30 in any week and 4–5 lost days per technician per year. The CDC puts absenteeism-linked productivity losses at US$225.8B a year — US$1,685 per employee.

In a pharmacy courier operation each no-show is a manual re-plan: dispatch phones around, cold-chain certs get guessed, a hospice med pass slips, controlled drops pile onto one driver, and the patient finds out last. That's the work Crisphive removes — inside the tools you already run.

Pick the surface. The same deterministic solver answers behind all three.

Call the solver from your own backend.

Your dispatch system already owns jobs, techs and contracts. Send Crisphive the delta — "tech 04 is out" or "new urgent stop" — and get back a complete, SLA-valid plan to write wherever you keep schedules. Idempotent, deterministic, versioned.

  • Event in, plan out. One call returns reassignments, new start times and a plain-language reason per move.
  • Webhooks for drift. Traffic, overruns and no-shows trigger re-solves you can accept automatically or review.
  • Nothing to host. Constraints and territories live in your tenant; we never see customer data you don't send.

Every service type carries its own credential, duration and window. The solver knows the difference.

  • Sealed red STAT delivery bag on the passenger seat of a courier car, hospital pharmacy entrance blurred through the windshield

    STAT / same-day clinical

    Oncology, post-discharge and hospice meds. Highest priority, injected into live routes.

Deterministic means the same inputs always give the same plan — auditable, explainable, no surprises at 6:30 AM.

  1. 010.0 s

    Event arrives

    A call-in, an overrun, a STAT oncology run — from your app, a webhook, a voice agent, or a sentence typed to Claude.

  2. 020.1 s

    Constraints load

    Certifications, SLA contract windows, live drive-time matrix, remaining daily capacity and territory rules for the affected day.

  3. 03< 3 s

    Deterministic cascade

    The engine re-sequences the whole connected day, not just the broken slot, and returns one reproducible plan with a reason per move — zero SLA breaches or it says so.

  4. 04you decide

    Preview, approve, write back

    Humans see every move before it lands. On approve, your system of record is updated and technicians and customers are notified.

Hard constraints the solver carries

  • Driver qualification cold-chain, controlled-substance, HIPAA
  • Dose windows med-pass cut-offs, STAT ≤ 2 h
  • Excursion limits time out of 2–8 °C
  • Capacity totes, cooler volume, hours
  • Chain of custody signature and ID rules

2408 jobs a year sit on an absent tech's route. At 85% same-day recovery, Crisphive re-sequences 2047 of them onto certified colleagues instead of a callback queue — plus 129 dispatcher hours not spent phoning around.

Illustrative. Lost tech-days and weekly rates are U.S. benchmarks from the sources above; dispatcher time assumes 45 min of manual re-planning per absent tech-day; recovery rate and ticket size are your inputs. Excludes overtime, backfill and SLA penalties.
