The property OS

Every property,
one system.

Guest messages from every channel land in one inbox, translated as they arrive. Bookings on Airbnb, Booking.com, and your direct site share one calendar. Short-term lets, long-term tenancies, and corporate stays — all in the same place, finally.

Opening first to a small group of people running mixed portfolios.

The problem

Five logins. Three calendars.
One overstay you heard about too late.

What it is

One calendar, every channel.

Airbnb, Booking.com, Vrbo, direct, corporate — synced both ways. A booking on one closes the dates on all. No double-bookings, no calendar you forgot was out of date.

One inbox, every language.

Every guest message, from every platform, in a single thread — translated as it lands, so you reply in their language without switching apps or copy-pasting into Google Translate.

One system, every property type.

Short-term lets, long-term tenancies, and corporate stays all in the same place. You shouldn't need different software every time the rental type changes.

A few quick questions and we'll point you to the right starting point.

Question 1 of 5

What do you rent out?
The threshold

Light under a door. The moment of arrival the whole system is built around.

What it replaces

Everything your stack does.
In one system.

Most tools do one thing well and stop there. Seraia runs the whole operation from a single place — and covers the ground the others leave bare.

  • Channel sync & calendar

    Two-way sync across Airbnb, Booking.com, Vrbo, Expedia & direct — one source of truth

    • A booking on Airbnb closes the date everywhere else, instantly.
    • Set rate rules and minimum stays once — they apply across every channel.
    • No more apologising for a double-booking you didn't see coming.
  • Direct booking site

    Your own commission-free booking site, branded and live

    • Every booking through your own site puts the OTA commission back in your pocket.
    • Branded site, custom domain — looks like yours, not a third-party widget.
    • Direct bookers tend to book longer and cancel less.
  • Guest messaging & round-the-clock concierge

    Every channel, every language, one inbox

    • Messages from Airbnb, WhatsApp, SMS and email land in one thread — no tab-switching.
    • Overnight check-in questions get answered in the guest's language while you sleep.
    • You only step in when a human touch genuinely matters.
  • Smart access & physical intelligenceThe moat

    Time-boxed codes, arrival and overstay sensing

    • Lock codes activate at check-in and expire at checkout — no manual rekeying.
    • Know a guest overstayed before your cleaner walks into a still-occupied flat.
    • Privacy-first — decibel signals at the threshold, never cameras indoors.
  • Trust, verification & fraud protectionPrivacy-first

    Know who you're letting in, before they arrive

    • ID verification and risk signals surface before you approve a booking.
    • Unusual reservations get flagged early — not after the damage is done.
    • Deposits and damage protection handled in the same flow as the booking.
  • Operations & housekeeping

    Turnovers, cleaners and contractors, auto-scheduled

    • Every checkout triggers a turnover job — no chasing your cleaner to check the diary.
    • Contractors, inspections and maintenance tickets all in one place.
    • Photo checklists mean you know the state of every property before the next guest arrives.
  • Contracts & documents

    Leases, agreements and guest docs, signed and stored

    • Digital leases with e-signature — no printing, scanning, or chasing signatures.
    • Guest, owner and supplier documents in one library, findable in seconds.
    • Compliance records and registry exports ready when you need them.
  • Dynamic pricing & revenue intelligence

    The right rate, set automatically, every night

    • Pricing adjusts to demand across the whole portfolio — not just your busiest property.
    • Occupancy, ADR and RevPAR in a dashboard you can actually read.
    • Forward-looking forecasts tell you where to focus next.
  • Payments & owner finance

    Deposits, payouts and owner statements, one ledger

    • Deposits collected, split payments processed — no copy-pasting into a spreadsheet.
    • Owner statements generate themselves at the end of each month.
    • Reconciliation happens automatically, so the books add up without the manual work.
  • Long-term & tenancy management

    The rentals other tools pretend don't exist

    • Rent collected on a schedule, arrears tracked without a separate system.
    • Renewal reminders, notice periods, and tenant portals built in.
    • Long-term and short-term tenancies run side by side — no switching tools.
  • Analytics, reporting & portfolio advice

    The whole portfolio, in numbers you trust

    • One dashboard across every property type — short-term, long-term, corporate.
    • Owner-ready reports generated in a click, not an afternoon.
    • Plain-language recommendations on what to fix and what's working.
  • Reviews & reputation

    Reviews and guest reputation across all channels, in one place

    • Review requests go out automatically after every checkout — nothing slips through.
    • Respond to every platform from one inbox without logging in five times.
    • Your reputation score tracked and benchmarked, so you know where you stand.

Most tools sit on top of a PMS. Seraia replaces it.

The moat, quietly

Know who arrived. Know when they should leave. Without a single camera indoors.

Seraia senses arrivals and overstays at the threshold using decibel signals and non-camera occupancy detection — disclosed to guests at booking, never surveillance.

The Signature Collection

More than management.
The parts no one else is building.

The everyday operation is the floor, not the ceiling. These are being built into Seraia now — named parts of the system, held to one premium standard. Early-cohort operators get them first, as each one ships.

  • Flagship · in early access

    Encore

    The second revenue moment, at every checkout.

    Guests book extras — a late check-out, a spa slot, a delivery — in one tap, at exactly the moment they're most likely to say yes. Encore closes the loop on the ancillary revenue that otherwise walks out the door with every checkout.

    • Set your offers once; the system surfaces them before arrival, mid-stay, and at checkout.
    • Anything a guest doesn't take is re-offered — but only when a slot is genuinely free.
    • A rating prompt follows each experience; anything short of glowing routes straight to you.
  • Being built

    Maître

    A concierge that answers at midnight, in the guest's own language.

    Maître handles the routine — early check-in questions, local recommendations, comfort on request, delivery coordination — around the clock, without the host lifting a finger. It escalates to you only when a human is genuinely needed.

    • Sits inside the unified inbox, keeping a full record of every conversation.
    • Answers in the guest's own language while you sleep — you stay out of it.
    • Hands over cleanly the moment something needs a person.
  • At onboarding

    Seraia Studio

    Your listing, shot right — before your first booking.

    Professional property photography with computer-vision cleanup and virtual staging, coordinated through onboarding at a partner rate no competitor matches. A property that looks right from day one earns more from day one.

    • A professional shoot booked as part of onboarding — not an afterthought.
    • Computer-vision retouching clears cables and clutter; staging added where a listing needs it.
    • Offered only to Seraia operators, through a vetted media network.

Named, and built to one standard. This is what comes next.

Why Seraia

Everything your stack does — in one system.

The point tools each do one slice well. Seraia matches what the category leaders offer, then goes further: it replaces the PMS layer entirely, senses what's happening at the property, and handles long-term tenancies the others quietly ignore.

Built for the whole portfolio
Built with real portfolios, not for a pitch deck

We're building Seraia alongside people running real mixed portfolios.

  • First access

    Early operators get on before the public waitlist opens.

  • Founding terms

    Pricing and terms that reflect your role in building Seraia with us.

We're working directly with operators running real mixed portfolios to build Seraia from the ground up. Quotes, case studies, and metrics will appear here as our early partners go live.

Questions

The things people ask first.

Does Seraia replace my PMS, or sit on top of it?
Seraia is the system of record — it replaces the PMS layer rather than bolting on top of one. During early access you can run it alongside your current tools and switch modules on one at a time as we open them.
Is the arrival and occupancy sensing camera-free and compliant?
Yes. Indoor sensing is privacy-first by design — decibel-level signals and non-camera occupancy detection, never cameras inside a property. It is disclosed to guests at booking and built to comply with region-by-region privacy law, including GDPR.
Which channels, locks and tools does it connect to?
The major booking channels (Airbnb, Booking.com, Vrbo, Expedia, direct), common smart-lock brands, and the messaging channels your guests actually use. We're expanding integrations with our early-access cohort.
When does access open, and what does it cost?
We're opening first to a small group of people running mixed portfolios — early access is invite-led, not a self-serve sign-up. The first 100 founders start with months free (up to 3, depending on plan) and lock in 25% off for life, a rate that holds while standard pricing rises. Join the list and we'll be in touch when your spot opens.
What does 'mixed portfolio' mean — do I need multiple property types?
Not necessarily. It means running more than one type of rental, or managing properties across more than one channel — a combination that today forces you to juggle several disconnected tools. If that's your situation, Seraia is built for you.
