Flyaps Reviews & Testimonials
Andrew Stetsenko
Founder at GlossaryTech, backed by Dice
5.0★
Python Django Review from Andrew Stetsenko
We partnered with Flyaps to build the GlossaryTech Chrome Extension from scratch, including the backend for tech terminology analysis.
The goal was to help recruiters, sales professionals, and other non-technical specialists in IT quickly understand the technical terms they encounter every day.
The first release shipped back in 2017, long before today's AI tools were available off the shelf. Flyaps built a custom tokenization layer on top of NLTK library to resolve the ambiguity problem - distinguishing "Go" the language from "go to the shop," or "Swift" the framework from the adjective, while also correctly recognizing multi-token terms like "Ruby on Rails" or "Amazon Web Services".
It was a pragmatic, precise solution that made the extension genuinely usable from day one.
The outcomes have validated that early bet. GlossaryTech now holds "Featured" status in the Chrome Web Store, has passed 25,000 downloads, and consistently serves 10,000+ weekly active users and 2,000+ daily active users. For a niche professional tool, that level of organic, sustained engagement is rare - and it traces directly back to the technical foundation Flyaps put in place.
Beyond the engineering, what stood out was how Flyaps engaged with the product itself. They contributed to architecture decisions, flagged edge cases early, and treated scope conversations with honesty rather than upsell. Communication was straightforward throughout, deadlines were met, and the codebase has held up well as we've extended the product over time.
I'd recommend Flyaps to anyone looking for a partner who combines solid engineering with genuine product thinking. They've been central to GlossaryTech's success and continue to be a team we trust.

Software Development Review from Dariia Ryzhova
Our collaboration with Flyaps has lasted for several major projects, of which I personally worked with them on two.
I am very satisfied with the level of expertise (both technical and domain), the involvement and responsibility of the teams, and the quality of delivery.
We successfully brought 2 major products to life together.
Flyaps teams have diverse specializations, so I had the opportunity to attract consultants from different fields: software developers, including high-level architects, DevOps, QA, and business analysts.
The teams have a modern technology stack and are experienced in Agile development. This allowed for smooth integration with internal teams and processes.
It is also important to note that Flyaps provides technical consulting on demand, and this was very valuable service as well. Overall, I can recommend working with Flyaps as a reliable and high-quality partner.

ТОВ ХОТНАЙТС's Review Sourced from Google
Flyaps delivered outstanding results for our e-commerce store! They built a visually stunning and high-performing website that perfectly captures our brand. Since launching, our site speed has improved by over 60%, and we've seen a noticeable increase in our conversion rate. Their team's technical expertise is top-notch, and the new admin panel they created has made managing our operations so much easier. I am happy to recommend this team of professionals.

AI Development Review from Oleg Sotnikov
Diffco built a complex, production-grade AI agentic system and backend for our client's fintech platform owning architecture, AI/ML components, and AI agents in a security- and compliance-sensitive environment. They delivered on time and within budget, communicated proactively, and operated like part of our own team, taking ownership and suggesting better solutions throughout. Deep AI/ML and senior backend expertise. We'd happily work with them again.

Mobile App Development Review from Julia Platova
We partnered with Diffco for a comprehensive software development project aimed at delivering a mobile application and backend system for our client.
The goal was to create a seamless, secure, and scalable solution within a 4-month timeline and $50k-$200k budget.
Diffcos team was highly professional from start to finish. They handled everything: UI/UX design, backend architecture, API integration, and deployment.
After the launch, they continued to support us with maintenance and performance optimization.
The application received positive feedback and has proven stable and scalable.
Were highly satisfied with Diffcos expertise, commitment, and ability to deliver real results.

Rick Tomsic
Founder and Chief Executive Officer at Tradovate, LLC
5.0★
Software Development Review from Rick Tomsic
Global business segment growth is requiring technology to keep up with the increase. Our platform is designed to be scalable and able to be implemented across several nations. We collaborated with Closeloop Technologies to work with our staff in order to scale up the programme.
An whole agile team is provided by Closeloop Technologies to participate in our programme. At first, we gave them the data in hopes that they would aid in our execution. They have combined Spring Boot, JavaScript, and AWS cloud technologies.
The platform is a value stream and full-suite insurance lifecycle. It is an internal iterative software programme.
Working with Closeloop Technologies is simple. They pick up new roles rapidly and possess agile team abilities that are industry standard. The staff not only fits right in, but they also contribute their knowledge and perspectives, making them a vital component of the programme.
Henrique Dubugras
Founder and Co-CEO at Brex
5.0★
Software Development Review from Henrique Dubugras
Services that had been slow or unavailable for weeks had to be brought back up. We must bring back our vital business role. After learning about our issue, the Closeloop project manager assigned a senior database specialist to address it. Our main programmer had a direct conversation with the database specialist of Closeloop after they listened to our problem and asked some follow-up questions. Within less than two hours, the solution to our issue had been verified and implemented.
Bill Rogers
Chairman and CEO at Truist
5.0★
Software Development Review from Bill Rogers
We occasionally utilize outsourced resources to increase our team's ability to satisfy the commercial demands of our clients. This time, my goal was to create and enhance the products we were providing to clients. Their engineers joined our own team to work on the project, creating MetaTrader-based software for our traders. They assisted us in creating and refining a suite of services that give our clients more functionality; up until that point, the solution had been erratic and unconventional. Their most recent endeavor was the development of an income trading module. We employed a scrum methodology with sprint deliverables and agile planning. Along with narrative points, we also used our in-house bug tracking application for project and task management. Everything was really accurate.

Empat Reviews & Testimonials
Angie Tromley-Morales, PMP
CEO at House Caddy
5.0★
Mobile App Development Review from Angie Tromley-Morales, PMP
We hired Empat to design and build the MVP of House Caddy, a household management app that keeps receipts, warranties, manuals, and repair history in one place, with reminders for expiring warranties and maintenance. The product also helps homeowners prepare a full digital home history for future property transfers.
Empat delivered end-to-end work: discovery, UX/UI design, Flutter mobile development, and a Python backend. They implemented a clear flow where users first create home appliances/systems and then attach documents and repairs to each item.
A major highlight was Empats AI expertise. AI features simplify the entire user journey by auto-filling appliance details from photos/docs/links, assisting with utility provider setup, and importing contacts to speed up adding contractors. This reduced manual input and made onboarding fast and intuitive.
Communication was excellent, with proactive brainstorming, clear sprint updates, and on-time delivery. The MVP is market-ready, early feedback is very positive, and Empat proved to be a reliable, product-driven partner with strong mobile, backend, and AI capabilities.
Vitalii Drach

Mobile App Development Review from Vitalii Drach
We collaborated with this team to develop custom software for tracking our client base and analyzing performance metrics. The solution allows us to monitor client success in real time, visualize key trends, and make data-driven marketing decisions.
The Empat team was professional, communicative, and highly attentive to our needs. They quickly understood our workflow and created a system thats both intuitive and scalable. Thanks to their work, weve streamlined our internal processes and gained much better visibility into our clients results.
Were very satisfied with the outcome and would definitely recommend Empat to anyone looking for a reliable software development partner.

We confidently recommend this team to anyone seeking a reliable, talented, and forward-thinking development partner.

I've been working with Simform for over six months now.

They've gone the extra mileeven over weekends and public holidaysto help us move faster when needed. Communication and project management have been excellent, with any issues swiftly addressed. It genuinely felt like Simform was invested in our success. Having worked with similar firms throughout my career, I can confidently say Simform stands out and comes highly recommended.

We worked with Simform to hire a front-end engineer for our SaaS platform. The process was well-organized, and their team was professional, responsive, and efficient. They quickly identified a candidate who met our technical requirements and ensured a smooth onboarding process.
Simforms communication and project management were strong throughout the engagement. They were proactive in addressing feedback and remained flexible in adapting to our needs. While there is some room for improvement in developer vetting and quality assurance, their overall service was excellent.
For companies looking to scale their development teams efficiently, Simform is a reliable partner. Their structured approach, responsiveness, and commitment to client satisfaction make them a great choice. We would recommend them without hesitation.

We engaged SolveIt to develop a minimum viable product (MVP) app, including a user-friendly iOS design, an artificial intelligence (AI) model, and a monetization strategy while ensuring General Data Protection Regulation (GDPR) compliance and preparing for future integrations. Despite a tight deadline, SolveIt delivered the app on time and efficiently handled beta-testing within three months, allowing us to gather feedback and launch successfully. We acquired our first 1,000 users within a month of launching the app. SolveIt's team communicated effectively, addressed issues proactively, and maintained a high level of autonomy, bringing diverse expertise that greatly benefited our project. We appreciate the agency's dedication and professionalism.

Aman Setia's Review Sourced from Google
The worst experience with the company. First they will call you and will ask you to go for 2 hours exam just like a half yearly or annual exam conducted during school time. After that they will ask you to wait for long. The interviewer will come and will ask only about your past company to attain it's strategies to move ahead and then they will ask you to go as we have a negative results regarding you. They will make you feel comfortable as if you will be selected and then the interviewer himself will be unsecured after seeing your profile, aa you are going to be a threat to them. As of now, they are not having any urgent requirements but calling you to waste your precious time only. Prefer not to go for an interview over here.

Squareboat has been a special part of my journey as a Mobile Engineer for the past 2 years (and counting). What truly makes it a great place to work is the people. You’re surrounded by incredibly smart driven individuals. That’s what makes showing up to work every day genuinely enjoyable.
From collaborating on diverse, challenging projects to learning from peers across different teams, the experience has been both rewarding and memorable. The culture is relaxed yet focused, and there’s always room to grow, explore, and contribute meaningfully. Highly recommend it for anyone looking to join a solid tech team!

Experience at Square Boat has been awesome! I've felt super welcome from day one. Even though I'm just an intern, I feel like my input matters and I've had chances to develop skills I didn't anticipate.
I'm early in my professional journey, but working at Square Boat has given me a real glimpse of what quality service actually looks like. The dedication to clients is genuinely inspiring.

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.
