From my initial consultation to the completion of the development process, the entire team at AppStem has been a pleasure to work with. With so many Mobile App Development companies to choose from, it's important to chose one who is willing to understand your needs and clearly outline a game plan before getting into development. If you're looking for more of a partner than just an agency, you're in good hands with AppStem.

Saba Sedighi's Review Sourced from Google
As a marketer its priceless to have a strong, and reliable dev / design agency who can get things done. I’ve worked with Mayven for a few years now and they don’t disappoint. From building microsites to working on marketing creative — they deliver what they promise, and communicate along the way.
Ben Standefer's Review Sourced from Google
At First Round we used Mayven to build out key parts of our app. I trusted Mayven when I founded my own startup, and have referred them to several VPs of Engineering at hypergrowth companies. Thumbs up all around - they’re quick, the code is clean and they’re great communicators.
Adam Hollander's Review Sourced from Google
We used several remote dev shops before Mayven but thank the good lord every day that we found them. If you've ever worked with a remote dev shop you know what a nightmare it can be, not with Mayven though.- outstanding communication and responsiveness- all devs speak excellent English- they can scale up or down your team on demand- founders are hands on- they have their own custom built project management tool that makes keeping tabs on or managing your project a sinchNot mentioning our devs name bc if you take him from our project...well...lets just say I'll find you lol.Highly recommend these guys, they're rockstars! If you're on the fence about working with them shoot me a note and happy to discuss to give you some behind the scenes insights from someone who has worked with them for over a year.

We selected Azumo to develop our software. We transitioned from another development company, so Azumo was initially responsible for migrating our existing code and environments. We are currently still working with Azumo as our nearshore software development team on adding new items to our software.

Azumo helped us migrate our existing UIs into a new framework, creating reusable components and the infrastructure needed for future development. The developer they assigned became a seamless part of our team, always punctual, responsive, and a great fit overall.

Web Design Review from Patrice Archer
They developed a SaaS web platform with smart scheduling and automation tools for us at and built the platform's front- and backend and integrated a custom analytics dashboard and calendar integrations. But to be honest what impressed us most was how deeply they engaged with our vision. They didn't just write code they challenged assumptions, proposed better workflows, and contributed as if they were part of our internal product team. Their ability to think strategically and focus on user experience made them feel more like tech partners than a typical outsourced vendor.

Software Development Review from Anonymous
We had created a conceptual framework to authenticate and verify the provenance, transaction history, and authorship of blockchain-based NFTs. Talentica was brought on board to test and refine the concept from both functional and engineering perspectives, and later to build a Minimum Viable Product (MVP) aligned with the agreed specifications and constraints.
Software Development Review from Anonymous
For several years, the team was composed entirely of Talentica contractors. Since January 2022, I have been directly managing them. The Talentica team handled the admin tooling backend, which included multiple Python Flask services with Postgres and Elasticsearch. These services operated in a service-oriented architecture deployed on Kubernetes, using Istio for service mesh and Spinnaker for deployments.
