Built for businesses like yours

  • Restaurants and takeout

    Take orders through the dinner rush without putting anyone on hold. Sempera knows your menu, your prices, and how long a pickup takes.

  • Clinics and dental

    Book, move, and confirm appointments straight into your calendar, so your front desk can look after the people standing in front of them.

  • Salons and spas

    Fill the chair that just opened up. Sempera books by service and by stylist, and answers the price question before it becomes a missed call.

  • HVAC and plumbing

    The no-heat call at two in the morning gets answered, triaged, and put on tomorrow's board before you wake up.

  • Electricians and contractors

    You cannot answer with your hands in a panel. Sempera takes the job, the address, and the callback time while you keep working.

  • Law firms

    Intake without the interruption. Sempera captures the matter, the parties, and the deadline, and flags a conflict before you call back.

  • Real estate

    Every listing enquiry answered while you are at a showing, with the viewing booked and the details texted to you.

  • Property management

    Maintenance requests logged with the unit, the issue, and the urgency, and the real emergencies put straight through to you.

  • Accounting and bookkeeping

    Answer the same five filing questions without losing an afternoon, and put the callers who actually need you into a real slot.

  • After-hours and overflow

    Start with only the calls you are already missing: nights, weekends, and the ones that come in while you are on the other line.

Frequently asked questions

Sempera answers your business phone. It picks up every call, answers questions about your hours, services, and prices, books appointments straight into your calendar, and texts you a summary afterwards. It works nights, weekends, and while you are already on the other line.

Plans run from $129 to $599 a month and each includes a set number of call minutes. Go over and the extra minutes are billed at a flat rate rather than your agent being cut off mid-call. If you go over every month we will move you to the plan that costs you less. No setup fee, and you can cancel any time.

Most businesses are answering calls the same day. Sempera reads your website to learn your hours, services, and prices, you check what it got right and correct anything it did not, then you forward your number. There is no build phase and no engineer to schedule.

Every call is recorded and transcribed, and those recordings are yours: read them, export them, or delete them whenever you want. Sempera runs on infrastructure certified to SOC 2 Type II and PCI DSS, encrypted in transit and at rest. Those certifications cover the platform Sempera runs on.

Yes. You keep your number and forward it to Sempera, either all the time or only when nobody picks up. Nothing changes for the people calling you, and you can switch forwarding off whenever you want.

Yes, and most businesses start exactly there. Forward only the calls nobody picks up, or only the ones that come in outside your hours. Once you have listened to a few weeks of them, send it more.

It transfers the caller to you, or takes a message, whichever you set for that situation. It does not guess and it does not invent an answer. Either way you get the recording, the transcript, and a text summary.

Yes. Agents handle English and French, including switching mid-call when a caller does. More than forty other languages are available if you need them.

Never miss another call.
