Sonder - Key Features and Functionality
Introduction
Sonder, a next-generation hospitality company, integrates advanced technology and AI to enhance the guest experience in several key ways.Automated Check-In and Keyless Access
Sonder utilizes smart locks that connect to a centralized operating system, allowing guests to check in digitally through the Sonder mobile app. This eliminates the need for a front desk, keycards, or physical keys. Guests receive a secure keycode sent to their app, enabling frictionless arrival and contactless check-in.Centralized Guest Management
The Sonder app and its associated technology enable hotel managers to control all aspects of the guest experience, including booking, check-in, guest communication, and check-out, all from a single, centralized platform. This automation allows for remote management of rooms, including setting temperatures and turning on lights before guests arrive, and ensuring rooms are ready for check-in.Enhanced Security
Sonder’s system allows for real-time monitoring and control of room access. Managers can change keycodes and settings instantly to address security concerns, such as suspected unauthorized access. This ensures that housekeeping staff cannot enter rooms when guests are inside, enhancing guest security and privacy.Personalized Guest Experience
The Sonder app provides guests with a personalized portal where they can customize their stay. Guests can request late check-out, contact staff, and access information about the hotel and surrounding area. This app-driven service ensures that guests feel taken care of throughout their stay.AI-Driven Efficiency
While Sonder’s primary focus is on automation and smart technology, the integration of AI is implicit in the efficiency and personalization of the service. AI can be seen in the background processes that analyze guest preferences and behaviors to optimize the guest experience. For example, AI can help in predicting and meeting guest needs, such as pre-setting room conditions or offering relevant recommendations through the app.Streamlined Operations
Sonder’s technology automates many routine tasks, such as staff scheduling and maintenance, allowing staff to focus on more complex and personalized customer needs. This automation reduces labor costs and streamlines hotel management and operations.Integration with Existing Systems
For hotels looking to adopt the Sonder model, solutions like Operto Boost allow existing locks to be upgraded with smart technology, enabling digital check-in without the need for a complete overhaul of the locking system. This makes it easier for hotels to integrate Sonder’s technology into their existing infrastructure.Conclusion
Overall, Sonder’s use of AI and advanced technology focuses on creating a seamless, efficient, and personalized guest experience, while also streamlining operations and enhancing security.
Sonder - Performance and Accuracy
Evaluation of Sonder’s Performance in Travel Tools
To evaluate the performance and accuracy of Sonder in the Travel Tools AI-driven product category, we can look at several key aspects of their implementation, particularly in relation to their fraud detection and booking process automation.
Automation and Efficiency
Sonder has significantly improved its booking process efficiency by implementing a machine learning-powered monitoring system in partnership with Persona. This system automates the review of bookings, reducing the manual review time by 75%. This automation allows Sonder to approve around 85% of bookings automatically, while flagging potentially risky bookings for human review. This approach has streamlined the process, reducing the cost associated with each booking and enhancing the overall guest experience.
Accuracy and Factual Relevance
The machine learning model used by Sonder incorporates over 50 distinct signals, including guest data, booking information, and other relevant factors. This nuanced approach helps in identifying fraudulent bookings more accurately than a manual review process. The system assesses various signals to make informed decisions, ensuring that the outputs align with the actual risk profiles of the bookings. For instance, the model can compare the ID used during check-in with the personal information on the booking to catch instances of non-compliance or stolen credit card use.
Limitations and Areas for Improvement
While Sonder’s AI-driven system has shown significant improvements, there are a few areas that require attention:
Continuous Improvement of Fraud Detection
The system relies on continuous data input and feedback to improve its accuracy. As fraud tactics evolve, the model must adapt quickly to new patterns. This requires ongoing updates and refinements to the machine learning algorithms to maintain high levels of accuracy.
Balancing Automation and Human Oversight
While automation has reduced manual review time, there is still a need for human oversight to handle complex or borderline cases. Ensuring that the balance between automation and manual review is maintained is crucial for optimal performance.
Data Privacy and Security
As with any AI system that relies heavily on user data, ensuring the privacy and security of this data is a significant concern. Sonder must adhere to global privacy regulations, such as GDPR, to protect user information and maintain trust.
Engagement and User Experience
The implementation of the AI-driven booking monitoring system has led to a better guest experience. Guests now receive quicker responses regarding the status of their bookings, which has contributed to an increase in Sonder’s Net Promoter Score (NPS). This faster and more efficient process reduces friction for both guests and Sonder’s Trust and Safety team.
In summary, Sonder’s AI-driven product has demonstrated high performance and accuracy in automating and optimizing the booking process, particularly in fraud detection. However, ongoing improvements in adapting to new fraud patterns, balancing automation with human oversight, and ensuring data privacy are essential for maintaining and enhancing the system’s effectiveness.

Sonder - Pros and Cons
Advantages
Consistent Experience
Sonder offers a consistent and reliable experience, similar to traditional hotels, but with the comfort and authenticity of a home-away-from-home. This includes hotel-style amenities like bathroom supplies and coffee, which are standard across all Sonder properties.
Streamlined Check-in
Sonder provides a frictionless, contactless check-in process using secure keycodes sent via their mobile app. This eliminates the need to wait at a front desk or deal with physical keys or keycards.
Enhanced Security
Sonder emphasizes security with features like doormen in some locations and contactless check-in, ensuring guests feel safe and secure during their stay. The use of smart locks and centralized management also allows for real-time monitoring and immediate response to security concerns.
24/7 Customer Support
Sonder offers 24/7 customer support through their app, and in-person attendants are available if virtual communication is insufficient. This ensures that guests can get help whenever they need it.
Automated Processes
Sonder’s use of technology automates many processes, such as check-in, guest communication, and room preparation. This can include setting the temperature and turning on lights before guests arrive, enhancing the overall guest experience.
Disadvantages
Limited Geographic Reach
Unlike Airbnb, which has listings in almost every country, Sonder is currently available in over 40 cities globally. This limits the options for travelers looking for accommodations in more remote or exotic locations.
Only Entire Units Available
Sonder only offers entire units for booking, which may not be suitable for travelers on a tighter budget or those who prefer shared accommodations.
Higher Costs
While Sonder sets a fixed price per listing with only taxes added, the overall cost can be higher compared to some Airbnb options, especially for shorter stays or more budget-conscious travelers.
Limited Flexibility in Booking Options
Sonder primarily caters to short-term stays and does not offer the same variety of rental types as Airbnb, such as shared rooms or long-term rentals.
Dependence on Technology
While the automated processes are a significant advantage, they also mean that guests are heavily reliant on technology for their stay. This can sometimes lead to issues if the technology fails or if guests prefer a more traditional, human-interacted experience.
By weighing these pros and cons, travelers can make an informed decision about whether Sonder aligns with their travel needs and preferences.

Alternatives and Competitors
Airbnb

AI-Driven Travel Platforms
Platforms like Expedia, Kayak, and HomeToGo are integrating AI into their travel booking processes but focus more on the planning and booking stages rather than the accommodation experience itself.
- Expedia’s Romie: Expedia has introduced Romie, an AI-powered travel assistant that helps with inspiration, planning, booking, and customer service. Romie can suggest alternatives in case of travel disruptions and provides AI-generated review summaries.
- Kayak’s Ask Kayak: Kayak’s tool allows users to input prompts about specific destinations and receives AI-generated information about flights, lodging, and car rentals. However, this tool is more about planning and booking rather than the accommodation experience.
- HomeToGo’s Super AI Sunny: HomeToGo is developing an AI tool to assist with search and booking, but it does not directly compete with Sonder’s focus on short-term rental properties and hotel-style amenities.
Conclusion
Sonder stands out for its technology-enabled, contactless service and consistent, hotel-style amenities. While other platforms like Airbnb offer a broader range of listings and AI-driven travel planning tools like Expedia and Kayak enhance the planning process, Sonder’s unique features make it a strong option for those seeking a seamless, secure, and amenity-rich short-term stay experience in major cities.
