The Lowdown

SubGuru is app-based management software that makes the substitution process easier and more efficient for both Instructors and Studio Managers.

How it Works

Instructors or Studio Managers log into SubGuru, find their class, and select “Request A Sub”. Our system will send a push notification to the designated instructor group assigned. Subs are able to accept or deny a request via the SubGuru app. SubGuru currently links seamlessly with the MindBody Platform and instructor changes are made automatically.

Why it Works

SubGuru fits your business’ workflow. Studio Managers have the option to set a customized Instructor Tier list for each type of class. SubGuru prevents errors by keeping all information and Instructor scheduling changes on one single platform.


Tier System

Select a substitute instructor based on class style, availability and experience level. Pools allow you to select your preferred substitutes and send out the request in a streamlined, systematic order.  

Mindbody Integration

SubGuru seamlessly integrates with MindBody to allow for real-time updates. Owners, Managers, and Members can see all schedule changes as they’re made.

Data Protection

Operate with the peace of mind knowing that your data is safe, secure, and never shared.

Messaging Platform

Streamline and organize your communications through our chat and announcement features. Substitution requests and approvals are done through the app, making the entire process hassle-free. 


Have more than one studio? Even better! Instructors can be requested to substitute a class across multiple locations.

Enhanced Communication

Keep your Team up-to-date with any schedule changes using our push notification feature.

What People are Saying

“There is a lot of guilt having to post on Facebook or send individual texts. Sub Guru eliminated that for me and I feel much better about my job.”


Yoga Instructor

“My favorite feature is the tier option! With this function, I know that the next best instructor is always notified without me stepping in! Sub Guru has also saved me so much time during the week. I no longer need to keep track of text, emails or even face to face conversation about subs! If you are an owner, you need to add Sub Guru to your business tools ASAP!”


Cycle Studio Owner

“My biggest problem BEFORE Sub Guru was communication. Filtering through multiple texts or often teachers not communicating changes to me. Sometimes the teacher would not change the class correctly in Mindbody and students would show to a class without a teacher. The second biggest issue was certain teachers were offered the bulk of classes while other qualified teachers were overlooked. This lead to feelings of favoritism within our organization. Sub Guru manages communication clearly and provides equal opportunities for all qualified teachers to sub. The value of my time has greatly increased and Sub Guru has made my life as a manager easier by streamlining communication while structuring the organization of subbing. I don’t have time to send multiple texts/make multiple calls to find a sub and group texts/emails are often ignored. My time is money. Sub Guru had saved me substantially in both areas. I am so grateful to have Sub Guru, the AMAZING owners who are such a blessing to work with, and a beautiful/seamless product that has saved me daily.”


Yoga Studio Manager

“If you own a yoga studio like me then you understand how frustrating it can be when a teacher cancels on a class with very short notice . This app has been a lifesaver for that. I absolutely love how this company has fixed an issue that has been going on forever. Thank you for allowing my business to run smoother!”


Yoga Studio Owner

“Where do start?! As an instructor in Los Angeles, I’ve had my fair share of issues finding subs for my classes. Some studios have you find your own, while others are left up to management. Using Sub Guru has not only saved me time, but it has taken so much STRESS of my shoulders! I am a PT instructor who also works a 9-5 and my schedule is forever changing! Oh and if you are an instructor reading this, you only get notified for the classes your actually teach! Amazing!”

Sarah Rasby, M.A.

CEO + Co-Founder

Sarah Rasby is no stranger to the fitness instructor substitution process! She is a former co-owner of a Yoga studio based in Lincoln, Nebraska since 2013. During her experience as a Regional Director, she found that quality instruction is the heartbeat of a studio. With the many responsibilities that come along with owning a studio, Sarah desired to build a strong, reliable and intellectual system to find and schedule Substitute Instructors for classes. From all the challenges, mishaps, successes, and mediation, SubGuru was created! Sarah's vision is to build conscious awareness and integrity within the fitness industry, and SubGuru is the management solution to do just that!

Andra Rasby, M.B.A.

COO + Co-Founder

Andra Rasby understands the sports and fitness industry from the inside out. She holds an MBA with a concentration in Sports Business, is a former Division 1 Athlete, and a certified Yoga Instructor. As both a Client and Instructor, Andra is well familiar with Group Fitness and the operations behind the Instructor Substitution process. She recognized a disconnect in finding the most appropriate substitutes for group classes. There were too many steps, lost emails, and last minute requests. With a desire to fix this problem, she teamed up with Sarah to design SubGuru and says, “I want Owners, Managers, and Instructors to spend less time worrying about finding the right Teacher and more on the quality of the class.”

Social Impact

Sub Guru believes that strong communities have the power to make an incredible impact. We are committed to giving back to our collective communities. With every dollar earned, we invest back into the community of Lincoln, Nebraska, where SubGuru was founded. Our current initiative is to support female entrepreneurship, helping them to realize their fullest potential and business aspirations.
