Software Development Review from Michael S.
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.

I own a marketing firm in Troy MO and I recently met with Calvin at Sketch Development Services to discuss a software development project I have been thinking about pursuing. He was very nice, easy to speak to and even though his field is a bit out of my knowledge base, he was able to explain things in a way that made perfect sense. I look forward to working with him and his team in the future and recommend anyone looking for a software or app development company to give them a try.

Software Development Review from Claus-Peter Mueller
We have engaged Infinum to develop an app that would digitalise our leasing process. From creating the initial offer through the necessary financing application and client identification to the final signature – all the steps required to successfully lease a vehicle or other object can be performed in-app, freeing the users of friction and having to deal with tedious paperwork.
The app itself in the background has 30+ integrations, while keeping a seamless and quick to follow process on the front for our users. That application is in production and Infinum is responsible for maintaining it and further improving. After the initial development, we have additionally expanded our scope from vehicles to other equipment. They have also developed a Leasing widget, product which enables quick financing model while purchasing a vehicle online on car seller marketplace pages.
At this moment, we are still in partnership with Infinum, and their engagement is mainly focused on localising the app to other countries and supporting us in our further business expansion. The work performed was done in Ruby on Rails and React technology, with support of other services.

We had created a conceptual framework to authenticate and verify the provenance, transaction history, and authorship of blockchain-based NFTs.

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.

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.

I had a great experience working with Tepia. Abraham, the Founder and CEO, was available, helpful, and actively involved throughout every stage of the process. Kimmy, my assigned project manager, was organized, responsive, and clear in her communication from start to finish.

Mobile App Development Review from Robert Beknazarian
Working with Tepia Co has been an exceptional experience from start to finish. They played a critical role in developing our mobile app for RELI, and I can confidently say they exceeded our expectations on every level
From day one, Tepia demonstrated a deep understanding of both the technical and business sides of app development. They didnt just execute tasks they asked the right questions, challenged assumptions when needed, and helped us think through complex workflows in a way that improved the final product. Their team truly operates as a strategic partner, not just a development vendor The communication was excellent throughout the entire process. We always knew where things stood, timelines were clear, and any issues or changes were handled proactively and transparently. For a project as complex as ours involving pricing logic, user flows, financing options, compliance considerations, and scalability this level of clarity and responsiveness made a huge difference.
What really stood out was Tepias attention to detail and commitment to quality. The app they helped build is stable, clean, intuitive, and built with long-term growth in mind. They were thoughtful about architecture, performance, and future enhancements, which is critical for a company like ours that plans to scale aggressively.
They were also extremely flexible and patient as our requirements evolved (which happens in real-world startups). Instead of pushing back, they collaborated with us to find smart, efficient solutions that aligned with our vision and budget.
If youre a founder or business owner looking for a team that:
Truly understands mobile app development
Communicates clearly and consistently
Thinks strategically, not just technically
Delivers high-quality, scalable work
I highly recommend Tepia Co without hesitation. They have been a trusted partner in bringing RELI to life, and we look forward to continuing to work with them as we grow

Translation Services Review from Abhit
They provide consulting services for a healthcare service provider. Sidebench contributed their expertise to a comprehensive mobile application to make sure it would pass Apple Store requirements. Thanks to Sidebench`s input, the application launched on the Apple Store after the first submission. Sidebench`s response times were quick, and they were willing to accommodate a unique working arrangement. The relationship that we had was probably unique; most companies would push to do the development themselves. We only needed Sidebench`s know-how, and they were willing to accommodate us.

I bought a variety pack of protein bites from the Made in Chicago Market. They taste really good and have a nice amount of protein. The chocolate chip cookie dough and fudge brownie are my favorites. The serving size is 3 seperate bites, but I was satisfied after 2. They are a great snack! If I’m just a little hungry and want something a tad sweet it’ll be great to just grab one from the fridge.

denny stearns's Review Sourced from Google
I bought the Carmela the other day. It is smoky, with burnt Carmel, marshmallow taste and smell. This is not my type of whiskey. I like smoke but there was something that disagreed with me. So this line is not my cup of... whiskey. Looking forward to trying their Bourbon and will update my tasting experience. The R6 distillery reached out to me which shows they care about their product. That goes far with me.
Update... I have now tasted the R6 Distillery Bourbon Whiskey. Very pleasant to the nose with light vanilla. Taste is smooth and not sharp. The taste is in my wheelhouse of Bourbons. Sweet, smooth vanilla, light Carmel. I hear you can get a bottle at COSTCO and i saw one on the shelf at the local convenience store in Gundo. I would recommend it.

We received selection of bourbons as a splendid gift from our friend. That was a first time we tried this product. We tested and tested different ones and enjoyed it so much, but did not have even a hint of a headache next morning! Amazing!

Victor Alpha's Review Sourced from Google
Great speakeasy, fine spirits, nice atmosphere. Drawback is licensing restrictions - only one cocktail or 1.5 oz total in spirits. Beers are unlimited. Another flaw is when a private event is scheduled, no notice is posted on the website, meaning if you’re traveling here from afar, you will have to travel right back spiritless and hopless.
Edit: When I checked the website I did not see the notice about the private event. If you say it was posted, then it was my fault for not being thorough. Also, the state did not want your missing stars and I have too many myself. They are all yours. And the gin was delicious. Cheers!

Had such great care here, all of the nurses were kind and friendly, I completely felt safe and listened to by the anesthesiologist and Dr Roost was excellent at explaining my procedure and clearly passionate and skilled in her field. Clearly no none wants to have a colonoscopy but their staff made it as easy and smooth as possible!

I was pleased with the services I received in the Waverley surgery center for my much procrastinated colonoscopy. Everyone was friendly, caring and attentive which made me feel comfortable and relaxed. Everything went smoothly, they gave clear instructions for after procedure and called next day to make sure
everything was all right. I highly recommend it.

Tony Greco
Review from Google
5.0★
Tony Greco's Review Sourced from Google
TDF provided us with product management, development, and strategic consultation. We started to build the product with an individual and had initial wireframes and mock-ups, but the project quickly grew larger than an individual person could handle. TDF evaluated what we had and gave us feedback, then created a plan to replace and fix what had already been done. They started with extensive customer development-- something we missed the first time around-- so their new wireframes and plans were based on what our customers actually wanted. Then, they executed the plan.
In addition to the development work, they also took care of logo and design work. They used Amazon Web Services for our platform. We have multiple features such as an API, database, and an administration tool for our own interface. We have a provider tool for facilities to update their data within the database. People can find resources on our web page, web application, and an iOS and Android app. We continue to work with them and have found it more effective and efficient to use them as a virtual outsourced department.

Tom Goddard's Review Sourced from Google
We are a consulting firm that specializes in working with healthcare organizations who are seeking to become accredited, stay accredited, or are working with particular healthcare legal compliance issues that we specialize in. The management of a typical accreditation process is complex for both the applicants and consultants providing them with help, so we wanted technology to help simplify and clarify that process.
The Development Factory developed and designed two important pieces of software for us that have gone through multiple iterations over the years. The most important is an online project management platform that has all of our resources in one place and allows us to have secure communications with our clients and exchange documents and feedback important to the accreditation process. The platform also provides dashboards for our clients that allow clients to track their process and see how they're doing based on our scoring system that scores any documentation that will be sent to accreditation organizations.
The second piece of software TDF built is a training program called AccrediTrain. We had a training software before, but they built a new self-service version that is completely automated, allowing a client to schedule a training for their employees without having to involve any of my staff.
As a result of the work TDF did for our firm, we are now able to handle a larger number of clients with the same number of staff, helping us to increase our revenues by a factor of four.
Beyond that, the reactions to our platforms have been outstanding. Just recently a new client was having her first experience with Goldfinch and she said it was just amazing. Another client of ours is a competitor and asked us for help on a project. This is an organization that has a particularly sophisticated knowledge about the accreditation process, and their CEO and president was very impressed by our software platforms.
They really listened to our description of what we do and how we do it and then turned that into software that quite beautifully captures what we do and how we do it. They clearly care about us and our satisfaction.

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 sinch
Not 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.

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.

Don't waste your time on them, they are not really hiring, just pretending like they do. Not sure why, maybe to collect some data on potential candidates.

Unprofessional approach to the recruitment process in finance. Watch out just not to waste your time.

Maintaining a website seems like it should be an easy thing, especially if you're using a tool like Wordpress, but it can be a serious pain. Fortunately, Dayspring has worked with our page for years and have made it so easy. They respond quickly to questions, know how to fix just about anything that we have trouble with and overall are very knowledgeable and patient. They're a great team to work with!

Dayspring Studio helped launched Jubilee's website back in 2015 and subsequently provided additional update. I had found Janet and other staff there to be super helpful. They were always responsive to our concerns and input. Everything was done in a timely manner. For someone who was not very tech-savvy, Janet was patient in explaining how Squarespace worked and how to adjust content as needed. We appreciated their thoughtfulness throughout the whole process.

Dayspring helped our company with a UX design project and with a rebranding project. They are consummate professionals and amazing designers. Easy to work with: they keep their deadlines and stay in budget. Can't recommend enough.

I am writing this review to express my utmost satisfaction with the exceptional service provided by OSP Labs . I had the opportunity to work with them on the development of a healthcare digital platform, and their level of professionalism and dedication were simply unparalleled.
From the inception of the project, the team demonstrated a comprehensive understanding of our goals and vision. They showed top-tier expertise in healthcare software development, employing innovative strategies to design a platform that was both user-friendly and robust in its functionalities.
One of the most impressive aspects of our collaboration was their commitment to consistent communication and support. The team was always readily available to address any queries or issues that surfaced during the development process. This open line of communication went a long way in ensuring that the project progressed smoothly and efficiently.

6 Frequently Asked Questions About Software Development Companies in California
What services does a software development company in California typically provide?
It offers the following custom software development services:
Custom software development: Designing, building, and deploying software tailored to specific user needs or business requirements.
Mobile app development: Building Android and iOS applications that leverage native device features such as Bluetooth, camera, and GPS for enhanced functionality.
Web app development: Building software that lives on a remote server and is accessed through a web browser rather than being downloaded onto a device's hard drive.
Website development: Designing and developing both the front-end and back-end of a website, with a focus on responsive layouts, intuitive interfaces, and practical features.
Cloud development: Software developers in California craft bespoke programs that run on cloud environments and allow for secure and easy data retrieval and storage, while offering cloud consulting services too.
Quality assurance: Conducting rigorous tests to identify and resolve potential issues and ensure the software solutions meet performance standards, user expectations, and regulatory requirements.
Maintenance and support: Performing software updates to enhance security, functionality, and performance.
How much do these companies charge for software development services?
Software development pricing in California is among the highest in the United States, driven by talent demand in hubs like Silicon Valley, San Jose, and San Francisco. California sits at the top end globally, often 30-70%more expensive than offshore alternatives.
Costs vary widely by experience level, project scope, and specialization.
In top-tier markets, software developers in California charge $160-$275/hr.
Costs by project
Small projects (MVPs, simple apps): $40,000-$80,000
Mid-size platforms: $80,000-$150,000
Complex systems (enterprise, AI, SaaS): $150,000-$300,000+
What is the Privacy by Design requirement in California?
Privacy by Design (PbD) in California is a core regulatory expectation embedded in the California Privacy Rights Act (CPRA) and the California Consumer Privacy Act framework.
Privacy by Design requires software development companies in California to build privacy into systems from the start, not add it later, integrate privacy into software architecture, business processes, and data flows, and consider user privacy at every stage of development and data processing.
This requirement applies to web and mobile applications, data pipelines and analytics systems, and AI and automated decision-making tools.
How long does it take to complete a software development project in California?
The average timeline for a custom software development company in California ranges from 3 to 12 months, depending on the complexity and scope of the project. While AI-augmented development tools have increased coding velocity by nearly 40%, stricter California regulations (like the CCPA and new AI transparency laws) have added mandatory compliance and testing phases that offset those gains.

Model training, ADMT audits, and data lineage.
Can I hire a California agency that uses offshore developers?
Yes, you can. Many top software developers in California use offshore or hybrid teams. In this setup, the agency usually keeps its strategy, design, and project management in California, while teams in Eastern Europe, Latin America, or Southeast Asia handle heavy-duty coding.
While the model is effective, California’s strict laws mean that a software development company in California must be the shield for your business. Even if developers are offshore, they may have access to your users' personal data. Under the 2026 CCPA rules, you must ensure the agency has Data Transfer Agreements in place. The data must be handled as if it never left California.
What is the ADMT regulation?
ADMT stands for Automated Decision-Making Technology. In the context of California law (specifically the CCPA/CPRA), it refers to any technology that uses computation to replace or substantially replace human involvement in making decisions about people.
As of January 1, 2026, new regulations from the California Privacy Protection Agency (CPPA) have officially taken effect, placing strict guardrails on how businesses use these tools. If the software solution you need uses AI to make decisions, a top software development company in California must provide a way for users to opt out and receive an explanation of the logic.
The regulation targets any system, including artificial intelligence, machine learning, and simple algorithms that process personal data to make a significant decision concerning a consumer.
This includes decisions related to:
Employment: Hiring, compensation, or work allocation.
Financial Services: Lending, insurance, or credit.
Essential Services: Housing, healthcare, or education enrollment.
