Company profile

researched Aug 2026

{"summary_one_liner":"Supahost builds agentic AI that handles guest messaging and operations for short-term rental hosts and property managers.","detailed_description":"Supahost (branded Supahost AI) is an AI property management assistant aimed at short-term rental hosts, property managers and hotels. Its core product is a unified inbox that consolidates guest conversations from channels such as Airbnb, Booking.com, Vrbo, Gmail, WhatsApp and SMS, combined with AI agents that draft or autonomously send replies in the host's own tone, learned from property details and past conversations. The company markets support for 150+ languages and 60+ tools, and states that most hosts complete onboarding in under 15 minutes by importing properties, bookings and message history from existing platforms.\n\nBeyond messaging, the platform advertises a set of task-specific agents β€” inquiry, guest AI, CRM, cleaner, reviews, escalation, guest journey and marketing (listed as coming soon) β€” that cover cleaner coordination and scheduling, smart-lock/door-code issuance, scheduled guest journey messages (check-in instructions, mid-stay checks, checkout reminders, review requests), owner reporting and escalation of sensitive or low-confidence conversations to a human queue. Higher tiers add a voice AI phone line answering guest calls, a website AI booking widget, and a branded guest app. Add-on modules cover smart locks, automated police guest registration and electronic invoicing, reflecting compliance requirements in European rental markets.\n\nA mobile app, published under the developer name Apmi Inc. (Dover, Delaware, United States), is available on Google Play in the Productivity category with 10+ downloads recorded and a listing update dated 2026-08-19. The company also runs a blog on Ghost covering AI phone agents, escalation handling, multilingual replies, WhatsApp Business integration and Spanish short-term-rental registration rules.","business_model":"Subscription SaaS sold directly to hosts and property managers, priced per active property per month with a perpetual free tier, 14-day trials on paid tiers, and paid add-on modules.","revenue_model":"Tiered per-property subscriptions: Free (up to 10 properties, ~30 AI copilot drafts/month, one channel connection, one seat), Starter at EUR 3.69 per active property/month, Pro at EUR 9.24 per active property/month, and Scale at EUR 15.40 per active property/month; properties with no bookings in a month are billed EUR 1 while retaining full functionality. Annual billing is discounted 12% and a 30% discount is indicated for customers who already have a PMS. Add-ons are priced at EUR 5/lock/month for smart locks, EUR 4/property/month for police check-in registration and EUR 3/property/month for e-invoices. Payments are processed through Stripe.","target_customers":"Short-term rental hosts and Airbnb superhosts, professional property managers with portfolios ranging from a few boutique units to dozens of apartments across multiple countries, plus hotel and mid-term rental operators addressed by dedicated pricing modes.","go_to_market":"Self-serve product-led motion: a free, no-credit-card plan and 14-day trials on paid tiers, one-click import of listings and message history, and integrations with OTAs and 40+ property management systems (including Guesty, Hostaway and Lodgify) as distribution and onboarding channels. Sales-assisted options exist for the Scale tier and enterprise/custom plans (contact us, emailed quotes, scheduled calls). A content blog and a Google Play mobile app support acquisition.","technology":"LLM-based agents that learn a host's tone, house rules and edge cases and store them as reusable \"AI Memory\" applied to each reply. The system operates in two modes β€” Copilot (AI drafts for human approval) and Autopilot (AI sends automatically) β€” with confidence-based escalation and topic-based escalation routing to a \"needs your attention\" queue. Additional components include automatic translation across 150+ languages, channel-manager synchronization of availability, rates and messages, smart-lock control and automatic door-code generation, cleaning-gap detection and cleaner scheduling, and a voice AI phone agent that answers guest calls in 30+ languages using booking context and can transfer to the host.","market_position":"Positioned as an agentic AI operations layer for hospitality rather than a general property management system, working alongside existing PMS and OTA tools; a third-party startup directory classifies it as a seed-stage Real Estate & PropTech company. Site claims include being \"rated #1 for AI messaging,\" which is self-reported and unverified.","differentiation":"Emphasis on autonomous execution of operational tasks (cleaner rescheduling, lock/access handling, scheduled guest journey messaging) rather than reply drafting alone; replies tuned to each host's voice from property data and prior conversations; unified cross-channel inbox; broad language coverage; per-active-property billing that drops to EUR 1 for idle listings; and compliance add-ons for Spanish/EU registration and invoicing requirements.","traction":"Public claims are limited and self-reported: \"trusted by superhosts managing 1M+ messages,\" over 250 five-star Airbnb reviews attributed to customers, and 99% of guests rating communication five stars. Named reference customers on the site include Polina (4bedsandmore.com, 25 apartments, Vienna), Ethan (3 units, Paris), Everlease (45 apartments across 5 countries) and Maria (24 units, Madrid). The Android app shows 10+ downloads. A directory lists the team at 1-10 employees.","geographic_footprint":"European focus with customer references in Spain (Madrid, Barcelona, Tarragona), France (Paris), Austria (Vienna) and Andorra, and Spanish-market regulatory content (SES.Hospedajes, Madrid VUT licensing). One directory lists the company's location as Spain; the Google Play developer address is in Dover, Delaware, United States.","founding_story">"According to a startup directory profile, the founders grew up in a family of property managers and built the product in response to after-hours guest issues and turnover-day operations, describing existing tools as clunky and requiring constant supervision; the team combines hospitality background with engineering experience from Google, Wise, Accenture and MongoDB.","company_history":"Founded in 2025 and listed as seed stage by a startup directory. Product content published through 2026 documents successive capability launches, including escalation handling, multilingual replies, WhatsApp Business number integration, configurable AI Memory for house rules, and an AI phone agent for inbound and outbound guest calls. A mobile app is distributed on Google Play under developer Apmi Inc.","latest_developments":"Blog posts in mid-2026 describe an AI phone agent answering guest calls 24/7 in 30+ languages from live booking data and ringing the host when needed (2026-07-17), guidance on Madrid short-term rental registration (2026-07-16), an AI Memory feature for teaching house rules and tone (2026-07-02), AI replies on a host's existing WhatsApp Business number (2026-06-25), automatic multilingual replies (2026-06-24), and configurable escalation with a needs-attention queue (2026-06-23). The Android app listing was updated 2026-08-19.","risks_controversies":"Nearly all available information is self-published by the company (website, pricing page, blog, app store listing); traction metrics such as \"1M+ messages\" and \"#1 for AI messaging\" are unverified. The Google Play listing shows only 10+ downloads and states the app may collect location, personal information and eight other data types. Operating in short-term rental markets exposes the company to local registration and licensing regimes (e.g., Spain's SES.Hospedajes and Madrid VUT), and the product depends on continued access to third-party OTA and PMS platforms. A separate UK web-hosting business also uses the Supahost name, creating brand ambiguity."}
