Overpriced.Just because they are on top of the Google search doesn't necessarily make them the best.You will get a call from US number, california just to impress you and make you believe that you are working with a sophisticated and hifi company.Have been requesting the backup of my website for ages now, no reply received yet.Dont trust them just like that. If possible visit them and meet them.I am in Bangalore and this address is wrong.

I’ve been working with Dinesh and the WebExcellence team for several years now. We run an international leadership programme for high-profile CMOs, and Dinesh is our go-to partner for both our website and educational platform.He has supported us with everything from building and maintaining the platform to integrating livestreamed webinars via YouTube, and he also developed my personal website. Across all of this, his work has been consistently high quality.Dinesh is fast, highly responsive, and reliable, but what truly sets him apart is that he’s also a wonderfully kind and thoughtful human being. It’s rare to find someone who combines technical excellence with such a collaborative and generous approach, and I couldn’t recommend him more highly.

Working with AgileTech has been an amazing experience, especially when it comes to creating a personalized e-learning program for our IT services business. We were pleasantly surprised by how adaptable and scalable the platform developed by the AgileTech Team was. Their proficiency with user-friendly course administration and community participation technologies enabled us to provide a thorough instructional resource catered to our customers' particular requirements. The platform has greatly improved our operational efficiency, and we are amazed by its capacity to manage heavy traffic with ease and offer comprehensive reporting and analytics. The platform remained successful and user-friendly because of the team's dedication to continuous support and their quick response to criticism. For any organization looking to create innovative and reliable digital solutions, we wholeheartedly recommend AgileTech as a partner.

Software Development Review from Preci Capiral
AgileTech provided a superb Learning Management System (LMS) that creatively and precisely addressed the intricate needs of our organization. Within a scalable, completely customizable platform, the LMS made it possible to create comprehensive courses, administer student tests, engage the community, and obtain real-time data insights. AgileTech's modular and agile approach made sure that every component, from the user-friendly course builder to the sophisticated analytics and communication tools, was customized to meet our demands despite the difficulties of developing such a feature-rich system. In order to guarantee perfect scalability and zero downtime, even with high user concurrency, AgileTech used a potent tech stack that included PHP, React, and AWS. Their post-launch assistance, which included frequent training sessions and upgrades, gave our staff the means to fully use the LMS's potential. This project was a testament to AgileTech's technical skill, rapid deployment, and dedication, making them an outstanding choice for educational technology development.

We have been working with Dinarys on our Shopify store for quite some time, and the experience has been great. From the very beginning, communication was clear, efficient, and reliable. The Dinarys team consistently delivered detailed proposals, stuck to agreed timelines, and offered well-structured solutions tailored to our needs. Their technical expertise is impressive, but what really sets them apart is their proactive attitude and genuine commitment to our project. Whenever we had questions or changes, they responded quickly and constructively. Its a true pleasure to work with a partner who feels like an extension of our own team. Highly recommended!

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.

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 levelFrom 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 developmentCommunicates clearly and consistentlyThinks strategically, not just technicallyDelivers high-quality, scalable workI 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

Software Development Review from Amarind Tan
Idea Maker was fantastic to work with. They completed multiple website projects for my virtual assistant agency. Each time they over delivered. Besides that, they helped build some AI automations to help my customer support. That freed me up to focus on expanding my partnerships. I really love the fact that they can do just about anything technically. They truly are my technical back office!

Clayton Hoarell's Review Sourced from Google
AJProTech provided a feasibility study for my fitness startup. The team was responsive, attentive, and easy to reach. Alex is a great leader and pays attention to detail heavily. He stays actively involved in the process and is a pleasure to do projects with. Overall the feasibility study was very well done. They consider all real world factors like cost and mass production. The team also made sure that they were always in alignment with our organization's goals. The actual deliverables that they provided like 3D renders, engineering solutions, industrial design, and overall roadmap to production are very well done. I would highly recommend the firm to anyone looking to develop a product. Alex and the team's real world experience make them world class in delivering results and helping you navigate the complex space of product development.

I've had the pleasure of working with AJProTech for my startup, My Gun’s Been Moved. We initially connected while we were exhibiting at CES, and they immediately stood out for their professionalism and deep understanding of product development.Throughout the process, Alex and the team have been incredibly thorough and accommodating—from the feasibility study to refining our initial product design. They were especially helpful during a critical time when we were locking down our intellectual property, ensuring that our development process remained smooth and aligned with our long-term goals.Their team is genuinely invested in helping founders bring their vision to life. I highly recommend AJProTech to any founder looking for a reliable and innovative hardware development partner. I;ve loved working with them and am excited to go to market with our product!— Kayla Austin, Founder of My Gun’s Been Moved

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.

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.
