The app has had 20,000 downloads over a period of nine months. Stakk is accommodating to timelines and communicates via weekly Zoom meetings, phone calls, and emails. ""Stakk has been flawless from start to finish."" **BACKGROUND** Introduce your business and what you do there.I'm the founder of a startup that offers an education-based application. **OPPORTUNITY / CHALLENGE** What challenge were you trying to address with Stakk?I needed support to develop our mobile app since I was starting my company. **SOLUTION** What was the scope of their involvement?Stakk has designed the entire app along with myself. The team has created and continuously tested all the UI designs and prototypes. Stakk has taken about nine months to release the first beta version of the app and launched the official app within a year of starting our engagement. The app includes different functionalities, including custom flashcards, support videos, and a two-way payment mechanism where students can pay, and we can also pay our tutors for their work. Stakk has also designed custom whiteboard technology that allows users to write on the phone with their fingers. The app is compatible with iOS and Android devices, including phones and tablets. What is the team composition?My main point of contact is Girish (Senior Product Lead), and I also work with a team of 5–6 developers based in India, although my interactions with them are limited. I also interact with a lead developer.How did you come to work with Stakk?I don't have a technical background, so I started searching for companies on Google and found Stakk's profile on Clutch. I found the reviews valuable, especially for professionals who are working in app development for the first time. We approached 5–6 development companies and selected Stakk because they offered the lowest budget for the same scope of work. How much have you invested with them?We've spent around £60,000–£70,000 (approximately $79,000–$92,000 USD) so far, and we plan to spend another £20,000–£30,000 (approximately $26,000–$40,000 USD).What is the status of this engagement?We began working with Stakk in September 2022 and launched the official app in September 2023, when the school year started. Since then, we've had about 20 builds continuously growing throughout the year, and we're now embarking on a new round of development. **RESULTS & FEEDBACK** What evidence can you share that demonstrates the impact of the engagement?Between September 2023–June 2024, we had about 20,000 downloads without paying any marketing ads. These metrics show that Stakk did a great job in creating an app clean design and friendly functionality for the user. We have around 4,000 monthly users and a score rating of 4.8 stars on the App Store. The team has been great and flexible throughout the project. Developing an app requires a lot of revisions and changes I didn't foresee when we started, and Stakk has been adaptable and kept the same price, which is a significant aspect of my startup. We've needed a lot of changes and new features, and Stakk has done all the work within the original scope. In hindsight, Stakk was the best company we could've picked because it's good to work with a team that is so accommodating and doesn't charge extra for revisions. How did Stakk perform from a project management standpoint?Stakk's project management has been the best part of our engagement. When I receive investments, I need to work quickly, and the team has accommodated that. Stakk offers many monthly plans that include maintenance and development hours, and if I need extra hours in a certain month, the team makes it work for me, which is great. Stakk lets me test something if I need to and fixes issues reported by users.We meet with Stakk via Zoom for half an hour each week to have an update on their development progress. When we have large-scale development, Stakk is available for a phone call whenever we need to reach them. The team is also responsive via email and responds within half an hour, even if we need them to fix a bug or an issue; Stakk usually has a solution within half an hour. Girish is my main point of contact for timelines and feedback. All my interactions with the team have been significant, and they're always available when I email them and respond to me quickly. Are there any employees from the service provider's team that you would like to give a shout-out to in this review?Girish is very easy to communicate with and understands both my and the developers' points of view. Having Girish as a middle contact is easy, and he tries to be as accommodating as possible. What did you find most impressive about them?Stakk has been flawless from start to finish in terms of price, offering good value for money. The quote offered by Stakk compared to other providers I talked to was around 50% cheaper, and I have primary contact with the co-founder. Girish cares about the company, and dealing with the company founder instead of an employee makes a huge difference in quality and how much they try to keep customers happy. Although this is my first time working with a development company, I've talked to other colleagues who have had a variety of positive and bad experiences working with development teams. I've heard experiences ranging from having major issues with development teams to not fulfilling the required development and having huge price increases for specific requests. I'm grateful because I haven't had bad experiences with Stakk.  Are there any areas they could improve?I haven't seen anything Stakk can improve. Do you have any advice for future clients of theirs?I suggest considering the entire UX when you first design the app because that will help Stakk provide a more accurate price. It's not necessarily something all clients think about at the start of development, but it will avoid adding extra work later in the project.  --- ## Portfolio & Awards ### MyCoach MyCoach is a fitness app designed to cut through the toxic side of the industry, offering personalised training, expert coaching, and a supportive community.

As a general guide, a simple app or MVP typically takes 2 to 4 months, a moderately complex app takes 4 to 6 months, and a full enterprise application can take 6 to 12 months or more. Every project begins with a Discovery phase where we define your requirements and map out a realistic timeline. From there, you'll have complete visibility at every stage, with a dedicated team working to hit every milestone. We pride ourselves on delivering on time and often ahead of schedule. Get in touch and we can give you a more precise timeframe based on your specific project. **How many clients do you work with at a time?** We work with a select number of clients at any one time to ensure every project receives direct attention from our directors. You will always have a senior, hands-on team behind your project rather than being passed down the chain. **How do you measure success?** Success for us goes beyond simply delivering a product on time and on budget. We measure it by the real world impact our work has on your business, whether that is increased user engagement, revenue growth, or a product that your customers genuinely love. From the outset we set clear goals and measurable outcomes with you during our Discovery phase, so everyone is aligned on what success looks like before a single line of code is written. Throughout the project our directors remain closely involved, ensuring quality is never compromised and that every decision is driven by your objectives. Ultimately, we consider a project a success when our clients come back to build the next thing with us and many of them do. **What is your team's process like for onboarding new clients?** We make onboarding as smooth and straightforward as possible. From your very first conversation with us, you will have direct access to our directors who will take the time to properly understand your business, your goals and your vision before anything else. From there we move into our Discovery phase, where we work closely with you to define your product, map out user journeys and identify exactly what success looks like. This is the most important part of the process and we never rush it, because getting this right sets the foundation for everything that follows. Once Discovery is complete you will have a dedicated team in place, a clear project timeline and full visibility of every stage from design through to development, quality assurance and launch. Throughout the entire journey you will have a named point of contact and direct access to the people actually building your product, not just an account manager relaying messages. We have refined this process across 120 projects and over 10 years, so you are in experienced hands from day one. **How do you typically collaborate with clients?** We believe the best products are built together, not handed over at the end. From day one you are an active part of the process, not a bystander waiting for updates. Our directors are involved throughout, giving you direct access to senior decision makers at every stage. You will have a dedicated point of contact, regular check-ins and full transparency on progress, so you always know exactly where your project stands. We use a combination of collaborative tools to keep communication clear and efficient, adapting to whatever works best for you and your team. Whether that is weekly video calls, shared project boards or direct messaging, we fit around you rather than the other way around. We don't just build what you ask for. We challenge, refine and improve your ideas along the way, bringing over 10 years of expertise and 120+ completed projects to every conversation. Our clients tend to think of us less as a supplier and more as an extension of their own team. ## Verification Premier Verified means Clutch independently confirmed Stakk is a legally registered business, financially sound (Creditsafe: Very Low Risk), and backed by 27 verified client reviews averaging 4.9 stars. - Verified Client Reviews: 27 - Overall Review Rating: 4.9 Last Updated: 2026-08-18T08:52:19Z ### Business Entity - Business Entity Name: Stakk Limited - Source: Companies House - Jurisdiction of Formation: United Kingdom - Date of Formation: February 12, 2020 - Status: Active - Last Updated: June 7, 2022 - ID: 12458461 ### Credit Report Results - International Credit Risk Assessment: Very Low Risk - Source: Creditsafe - Last Updated: January 1, 2022 ## Locations (5) ### London, England (Headquarters) - 37 Lombard Street, 6th Floor, London, EC3V 9BQ - London EC3V 9BQ - England - 10 - 15 employees - Phone: 02033144040 ### Wilmington, DE - 2664, 1007 N Orange St. 4th Floor , Wilmington, DE, US, 19801 - Wilmington, DE 19801 - United States - 1 employees - Phone: +1 646 741 2226 ### Amsterdam, Netherlands - 165 Albert Cuypstraat - Amsterdam 1073 BC - Netherlands - 1 employees - Phone: +44 020 3314 4040 ### Orlando, FL - 750 North Orange Avenue, Apt 4205 - Orlando, FL 32801 - United States - 2 - 5 employees - Phone: +1 646 741 2226 ### London, England - 8 Devonshire Square - London EC2M 4PL - England - 2 - 5 employees - Phone: 020 3314 4040 ## Contact Stakk [Send a message](https://clutch.co/profile/stakk) ### Connect on Social - [LinkedIn](https://www.linkedin.com/company/stakk) - [Instagram](https://www.instagram.com/stakkhq/)
