Software Development Review from Slava Berkovich
SapientPro consistently delivers high-quality work that aligns with project requirements. The team demonstrates strong expertise in Angular, TypeScript, and JavaScript. Their project management and communication practices are highly effective, with weekly client meetings held to provide updates on progress and ensure alignment.
Software Development Review from Jeremy Ott
This team was extremely responsive from the start. They pulled together a comprehensive quote for my MVP and have delivered on all of the requirements. The daily updates from the product/project manager are extremely helpful and it’s clear that the team cares about the quality of work they deliver. The engineers working on the product are always willing to make recommendations and go above and beyond to make the experience and underlying infrastructure that much better.
eCommerce Development Review from Luc Vlekken
We've had the pleasure of working closely with this development team on several projects, and the experience has been consistently excellent. Not only are they highly skilled developers, but they also think along with us both from a technical and a product/customer perspective. Their proactive attitude, reliability, and ability to translate complex requirements into elegant solutions make them a true partner rather than just a supplier. Highly recommended.

Alexandra and GroupBWT did great job! Provided us with the detailed audit for our system, specified how it can be improved, what should be paid attention to during the re-design and provided the best practices we can utilize. Also they formed clear and detailed scope of work for the further re-design. They definitely know how audit should be performed and the deliverable was even beyond my expectations. Strongly recommend Alexandra and GroupBWT team!

eCommerce Development Review from Derek Ching
I had the pleasure of working with the Ebizon Digital team on our Klaviyo email marketing, Meta (Facebook) campaigns, and Google Ads and I can honestly say they've been outstanding.They are incredibly responsive, proactive, and reliable, keeping our project on schedule while delivering wonderful ad creatives for our Hawaiis Choice brand. After working with many digital marketers over the years, Ebizon truly stands out with their great communication and consistency.As someone who isnt very web or tech savvy, I especially appreciated how they took on the heavy lifting with programming, patiently explained their process, and followed through on every promise. The results in email and paid media performance speak for themselves.I look forward to a long-lasting partnership with Ebizon as we continue building our marketing and sales for Yick Lung Hawaiis Choice, sharing our snacks with customers around the world.

SoftDoes Reviews & Testimonials
Yuliia Ten's Review Sourced from Google
I started working with SoftDoes when our product had already grown beyond the point where small fixes were enough. We needed to rethink several parts of the system and make sure the next stage of growth would not create even more technical debt.The team got into the project fast. Within the first few weeks, they helped us identify the main bottlenecks, clean up several fragile integrations, and improve the parts of the platform that were slowing us down the most.One practical result was that a key operation that used to take around 4-5 minutes now takes less than a minute. I also saw a noticeable drop in recurring technical issues after the release.What I liked most was the way they worked with us. Very little ceremony, clear communication, good technical judgment, and a strong sense of ownership.I’d be happy to work with SoftDoes again on another complex software project.
Ryder Mackey's Review Sourced from Google
My experience with SoftDoes has been extremely disappointing. Their communication is terrible, the people I dealt with were highly unprofessional, and their pricing is absolutely outrageous compared to the value of the work being delivered.One of my biggest concerns is the company’s lack of transparency. From what I’ve observed, their development work appears to be outsourced to people in Ukraine through another company called Come Back Agency. Even when I searched for SoftDoes online, its website appeared to redirect to Come Back Agency.Take a look at their LinkedIn yourself. They present themselves as a Kansas City-based company, yet I couldn’t find a single employee listed as being based in Kansas City. That raises serious questions about their business structure, where their team actually operates, and who you’re really paying to develop your software.My interactions with the CEO, Orest, were particularly unpleasant. I found him extremely arrogant, dismissive, and condescending. He speaks to customers as though they’re beneath him. Rather than addressing legitimate concerns professionally, his attitude made an already frustrating experience even worse.Their Google reviews also raised serious red flags for me. Several reviewer profiles appeared to have AI-generated profile pictures, and the reviews themselves read as though they were written by ChatGPT rather than genuine customers. Many of these accounts had only ever reviewed SoftDoes.After I confronted them about these concerns, I noticed that some profile pictures had been changed to what appeared to be stock images, and the accounts had gained an additional review of random places. I cannot independently verify who operates these accounts, but the timing and patterns made me seriously question the authenticity of their online reputation.Nothing about my experience with SoftDoes has inspired trust. If you’re looking for custom software development, do yourself a favor and look elsewhere. Verify who you’re actually doing business with, who will be developing your software, and what you’re paying for.
Kevin Parker's Review Sourced from Google
We had been running a large part of our business through spreadsheets and a mix of different tools for years. We've grown past spreadsheets now. SoftDoes built a custom platform around the way our team actually works. That's probably what we appreciated most about working with them.

Software Development Review from Vladyslav Sorochan
A true tech partner who just gets it! Aqe has brought our rough software concept to life and turned it into a smart platform. The project covered everything from custom development to AI features and some pretty advanced data engineering. From the beginning, their team really took the time to understand what we were trying to achieve. They started with a clear discovery phase and built a solution that checked all the boxes in terms of functionality and ease of use.It is easy to work with their team, not only in terms of technical skills but also in how responsive and collaborative they are. They regularly improved features based on our feedback as we moved along and were always available when we needed support, even after the post-launch. Having that kind of ongoing help made a big difference.The results were a bit better than we expected. We saw a noticeable drop in manual work, smoother internal operations, and improved decision-making through real-time data.Overall, Aqe and their team really delivered what they promised, on time and within our budget. The whole experience was smooth, professional, and well-managed. Wed happily recommend working with them.

Steve Fecske's Review Sourced from Google
Internet Soft stepped in as my development team providing their team of programmers to my platform. They are a group of talented, skilled, and conscientious in everything they do, assigning the best people they have to the various types of technology I needed from UI/UX, php, API, and database. They adopted my platform as theirs and immersed themselves to learn the processes, concepts, and workflows needed to fulfill the promise of our platform's services. They apply their technical skills to understand and write the necessary algorithms. They work hard and diligently to get projects fully defined before undertaking, and then get it done on time. They test their work, present it to our marketing team, then tweak, then provide public testing, and only when ready, open full access to the target audience and advertising. They are well organized to execute our needs by providing a project manager and project leader who communicate with me as to what I want, select the right development talent, and then present it to them so they understand what is required. They have also given me direct access to the developers to further ensure they understand my vision and needs. I have enjoyed their hard work and we have endured the details. I look forward to the results, and proudly recommend Internet Soft for your technology.
Jenya Babadzhanova's Review Sourced from Google
Internet Soft is a great company with managers and employees that are motivated, reliable, and persistent in whatever they do.

i hired this company for three months to do some SEO work. About two weeks in I realized how poorly things were worded and just corny and sales-y the language was. I told them to change it over and over and they couldnt do it.I told them I wanted to cancel and go our separate ways. Now they are currently holding my money and will not give it back.

How to Hire a Software Development Company in California
What can California software developers do for businesses?
When businesses work with California agencies, they get access to a deeper innovation ecosystem, stronger specialized talent, and more experience building innovative solutions for high-growth markets.
California remains the undisputed global leader in software production and talent density.
The state is funding projects for software-defined submetering, managed EV charging, and vehicle-to-everything (V2X) platforms.
One 2025 grant approved $693,611 to fund managed charging analysis, and another state-backed project is developing a software-defined submetering solution for EV site hosts.
That points to real depth in energy software, grid tech, and mobility platforms.
For a business owner, hiring software development companies in California means tapping into the world's most stable and well-funded innovation hub.
As of early 2026, California's tech sector contributes approximately $541 billion to the state's economy annually.
This represents nearly 19% of California's total GDP, providing a level of infrastructure and talent density found nowhere else.
In 2026, California developers will become the first truly AI-native workforce.
San Francisco-based companies alone received 34% of all total U.S. AI funding in recent cycles, ensuring that agencies in this region have early access to the most advanced tools and talent.
For example, in 2025, Bay Area AI companies pulled in roughly 76% of the U.S. AI funding, according to industry reports.
About 93% of developers in the region now use AI coding assistants.
AI tools have reduced the time it takes for new engineers to get up to speed on complex codebases, ensuring that if your project needs to scale quickly, the software company can add talent without a significant productivity dip.
Gartner predicts that 40% of enterprise applications will be integrated with task-specific AI agents by the end of 2026.
Software developers in California build autonomous agents that don't just chat but also execute workflows, such as reconciling accounting books, managing supply chain logistics, or providing first-tier customer support without human intervention.
Early adopters of agentic workflows in California report a 25% reduction in operational overhead within the first year of deployment.
Because of the CCPA and SB 942 (AI Transparency), California agencies build innovative solutions with a Privacy by Design philosophy.
This prevents the compliance tax, i.e., the massive cost of re-coding an app later to meet mandatory state privacy standards.
For every $1 spent on high-end California software development, mid-market California businesses report an average 3.5x return on investment (ROI) within 24 months through operational automation and new revenue streams, according to recent industry analysis.
Why should I hire a California-based agency vs. an out-of-state one?
While out-of-state or offshore agencies offer lower rates, a custom software development company in California can be a stronger choice for your business needs if you want a partner with proven expertise that is closer to the state's talent, capital, and regulatory environment.
California's life sciences sector alone included about 16,000 businesses, 70,000 biotech R&D employees, and $60 billion in private investment in 2023.
If your business operates in healthcare, medtech, biotech, or regulated industries, California firms are more likely to understand those workflows and compliance needs.
In 2025, California partnered with Google, Adobe, IBM, and Microsoft to expand access to AI training for over 2 million students across public schools, community colleges, and California State Universities.
For buyers, that means local agencies are hiring from a workforce pipeline being trained around modern AI tools and workflows.
California has the strictest data and AI laws in the U.S.
Hiring locally means your custom software solutions are built to the highest legal standard from day one.
The state employs over 628,400 software developers, which is more than twice as many as Texas, the next closest state.
In 2026, the state announced a $2.75 million CCPA settlement with Disney, the largest CCPA settlement in California history at the time.
If your product handles consumer data, a software developer in CA is more likely to build software having these rules in mind from day one.
California is home to 33 of the world's 50 leading AI companies.
If your project touches AI development, automation, or data-heavy products, software development companies in California are more likely to work in that ecosystem every day.
In 2024, 15.7% of all U.S. AI job postings were in California, versus 8.8% in Texas and 5.8% in New York.
That makes California the deepest single-state market for AI hiring.
According to CalPrivacy, California's privacy regulator reported a $15.8 million budget in 2025, up from $12.8 million in 2024, and 54 positions in 2025, up from 40 in 2024.
That signals a growing compliance and enforcement environment, which is useful if you want a software engineering partner that takes privacy seriously.
California handles more than $675 billion in two-way trade and is the largest importer among the U.S. states.
Agencies in that environment are more likely to have experience with multilingual, cross-border, compliance-sensitive, and high-volume digital systems.
How do I choose the best software development firm in California?
Follow these steps to ensure you choose the best software development company in California for your business needs:
- Start with product fit
Choose a firm that has already built the kind of product you need: SaaS, internal tools, AI features, healthcare software, fintech, or eCommerce. Ask for 2-3 recent examples that match your exact use case, tech stack, and compliance needs. - Make privacy and compliance a selection filter
A strong software development firm in CA should be able to explain opt-outs of rules and regulations, consent flows, data minimization, and privacy-by-design in plain English before it writes a line of code. - Check whether the firm can scale with you
The best partner should support growth, maintenance, and hiring transitions. Ask how the agency staffs phases 1, 2, and 3 of growth. - Ask who owns the communication and delivery
Some custom software development companies in California sell senior strategy but push execution elsewhere. Require a named product lead, tech lead, and delivery owner in California or your time zone, plus a written cadence for demos, issue tracking, and risk reporting to ensure timely delivery and top technical expertise. - Use a scorecard before you sign
The safest way to choose is to score each firm on relevant case studies, technical depth, privacy/compliance readiness, team seniority, communication model, maintenance support, and commercial fit. A simple weighted scorecard will help you separate polished sales from real delivery capability.

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.
| Project type | Timeline | Key focus area |
| Minimum Viable Product (MVP) | 3-4 months | Core features only; rapid market entry. |
| Medium complexity SaaS | 6-9 months | API integrations, multi-user roles, and scaling |
| Enterprise-grade systems | 9-18+ months | Legacy migration, high security, and deep compliance. |
| AI-native platforms | 12-24 months | 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.
- Criminal Justice: Legal outcomes or profiling.
