Crisphive

Built for plumbing companies

Deterministic scheduling for plumbing companies, embedded in the software your techs already use.

Crisphive sits behind your existing dispatch board, CRM, or AI assistant. When a plumber calls in sick at 6:30 or a burst main lands mid-route, it re-cascades water-heater installs, drain calls and gas work across licensed, nearby plumbers in under 3 seconds — without missing a promised window, and without anyone learning a new tool.

Every job inside its window

The day Crisphive protects

  • Plumbing service van with a pipe rack on the roof and open side door showing fittings bins, parked in a residential driveway

    The route

    6–10 jobs a day per van: drain calls, water heaters, repipes, emergencies. One absent plumber is a day of broken promises.

  • View under a kitchen sink lit by a work light, P-trap half disassembled, open tool bag and towels on the cabinet floor

    The arrival window

    Customers take the morning off for a 2-hour window. Miss it and the review is written before the truck leaves.

  • Manometer clipped to a new gas line during a pressure test, yellow pipe and a shutoff valve in sharp focus

    The licence

    Gas, backflow and medical-gas work only go to techs with the right endorsement. 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 installation, maintenance and repair occupations, 3.2% of full-time workers miss part of any given week — and 1.7% of all 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 plumbing shop each no-show is a manual re-plan: the office phones around, gas endorsements get guessed, a water-heater install slips past the promised window, and the homeowner who took the morning off 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.

Plumbing work, modelled properly — 이 섹션 링크 복사링크가 복사되었습니다

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

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 burst main — 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.

1,204 jobs a year sit on an absent tech's route. At 85% same-day recovery, Crisphive re-sequences 1,023 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.

Runs in shadow mode next to your current planner until you trust it.

Crisphive reads your jobs, techs, certifications and SLA contracts through the connector you choose, proposes plans beside the ones your team makes by hand, and only writes back once you flip it live. Your system of record stays the system of record.

    Connect days

    Point a connector at your jobs, techs, certs and contracts. Read-only.

  2. 2

    Shadow mode weeks

    Crisphive proposes a plan for every real disruption beside the one your dispatchers make by hand. Compare SLA breaches, drive time and wrench time.
