the review
The client submitted this review online.
Please describe your company and your position there.
I’m the CEO of a data gathering platform, and we provide a one-stop platform to search over all of your information in social services like Youtube, Medium, Instagram, and many others
For what projects/services did your company hire Ptolemay?
As one of our values is saving users’ time we wanted to move from a web app to a mobile app that is faster, and more user-friendly.
What were your goals for this project?
Get 10,000 WAU, with 3.5% conversion, and attract round A.
How did you select Ptolemay?
A friend of mine recommended them back at the beginning of 2020 when we first come up with a concept.
Describe the project in detail.
Thanks to direct integration with services like Instagram, Facebook, Youtube, Medium once you like or bookmark something from there - information instantly reflects on Savenger and available for search, tagging and editing. So now all your data becomes organized and packed in one place.
What was the team composition?
The team consists of a Project manager, a Product manager with experience in 2 own startups, Flutter developer, a back-end developer, UX/UI designer, and QA-engineer. CEO has also actively participated - he helped us outline our vision and shared his experience in business process management.
Can you share any outcomes from the project that demonstrate progress or success?
Currently, we have about 500 WAU in our private-beta, refine the application and add more integrations with social services.
How effective was the workflow between your team and theirs?
They do usually reply very quickly, part of the team was also available every weekend when it was crucial for me. That’s the thing I really appreciate and can’t express how it was important for Savenger and our users.
What did you find most impressive about this company?
They are product builders. I don’t know the story of each of them, but the guys who were working with me suggested a lot of fresh ideas, brainstormed them over the call, and even helped me form interview questions to validate them.
Are there any areas for improvement?
The team is spread around the Globe, and I am really happy that I have a chance to work with them, still there is one thing to improve - English.

Please describe your company and your position there.
Being the CEO of Airmonth.com I would like to launch my startup in 2021Q3. Our service is Uber-like for monthly renting of business-class apartments based in New York.
For what projects/services did your company hire Ptolemay?
Ptolemay already finished the business analytics and UX/UI design phases. We just recently started mobile app development.
What were your goals for this project?
My goal with Ptolemay is pretty straightforward. We need to build a profitable mobile app and start beta testing in 2 months.
How did you select Ptolemay?
Interesting story. We met in NY starbucks 2 years ago and that time just talked about our prospective startups. So here we are, already building my product. We fully trust Ptolemay because they fully covered all our doubts about feature choice, idea validation, a design which to choose, and so on.
Describe the project in detail.
Easy. There are services like Airbnb and Booking which provide only daily renting, but some people would like to have monthly renting with business-class services. I have many friends in networking who will start use my services once I launch closed beta. Ptolemay team helped me to create a detailed technical specification for this project and even did competitor market research. We are creating a mobile app based on flutter.
What was the team composition?
Founders of Ptolemay whom I know personally for already two years. Once we started the project I met their team remotely: product manager and business analyst. I haven’t met with designers and developers, because I think its just a waste of my time.
Can you share any outcomes from the project that demonstrate progress or success?
Sure. You can visit my website airmonth.com We already validated my own idea together with Ptolemay team and started build mobile app right away once we received the first order.
How effective was the workflow between your team and theirs?
With founders I have contact on daily basis. With the team we love zoom calls.
What did you find most impressive about this company?
E2E consulting and support. Starting from business idea and covering even design and tech stack choice. They are successful startupers so they have good product management experience that was really relevant for me. I feel they are like my own team.
Are there any areas for improvement?
Yes. I think their services should be more expensive, but I hope it will not effect me :)
