The MVP In A Day program has been a game changer for me. As a non-technical founder, I built my prototype with Claude Code but my backend was all wrong. During the MVP In A Day session, Igor not only built out a structurally sound backend, but also taught me about the architecture along the way. I was building along with him rather than just handing everything off to a dev shop and hoping for the best. Since the first day, I've come back for a few more sessions to build new features with Igor. I feel confident that I can get a lot done on my own with Claude, but for the more complicated builds, it's awesome to have a trusted CTO for a few hours to hammer it out. I highly recommend FastCTO! It is perfect for non-technical founders utilizing AI coding tools to build their MVPS. You'll understand why architecture decisions are being made and level-up your own "coding" skills along the way.

Working with FastCTO and Igor has been an incredibly positive experience. Form the start, Igor took the time to truly understand the purpose behind what I'm building, not just the technical requirements. That made a huge difference in how clear and grounded the entire process felt. What really sets FastCTO apart is the honesty and transparency. There was no overpromising - just thoughtful guidance, clear tradeoffs, and decisions made with long-term scalability in mind. Igor felt less like a vendor and more like a true partner who genuinely cared about protecting the vision and avoiding costly mistakes. I highly recommend FastCTO to founders who want a trusted CTO relationship and a clear, realistic path from idea to execution.

I’m the founder of Corval.ai, where we’re building a SaaS platform for service contractors. I actually found FastCTO on my own — it wasn’t through a recommendation — and after interviewing a few similar firms, it quickly became clear that Igor and his team were the right fit. They matched me with a Senior Developer named Max, and I honestly couldn’t be happier. Coming from a finance background, I had built the foundation of my product from scratch, but I knew I needed experienced technical leadership to take it further. What I’ve received from Max and Igor has been incredibly valuable — not just in expertise, but in genuine support and guidance. I can’t imagine moving forward without them.

I had a lot of trepidation prior to working with Igor and the broader FastCTO team. My biggest concern was whether they’d care about building this product as much as I did. Just as important, I wanted to actually learn through the process , i.e. I wanted Igor to be patient with me as we built an MVP together - and he did just that... he was transparent in his process and his explanations from the start. Perhaps the best part was that he took complete ownership of driving to our outcome of building a functional MVP. We initially agreed on one session, but when it was clear he needed more time, he spent his time after-hours to continue the build and "hold up his end of the bargain", too often this type of experience as a customer goes overlooked, I was and remain super appreciative of him. I have a working MVP, a better understanding of the architecture, and a path forward, all because of Igor. I wouldn't hesitate to recommend working with Igor and or the broader FastCTO team.

Working with FastCTO has been transformative for our business. Igor's boundless energy and positive attitude are matched only by his candid, insightful analysis. For anyone considering a startup, I highly recommend investing time with Igor and his team to validate and refine your ideation process. His expertise has been invaluable, and I enthusiastically recommend his services to any entrepreneur looking to strengthen their technological foundation.

I cannot recommend FastCTO highly enough! In my conversations with Igor, it’s clear that he operates with a rare combination of deep technical expertise and genuine kindness. Igor doesn’t just offer advice—he shares practical, actionable insights grounded in what he knows has worked (and what hasn’t). His approach is refreshingly pragmatic, cutting through the noise to help founders implement technical capabilities in cost-efficient ways. This guidance is invaluable for early-stage founders who often spend countless hours and dollars on things they think they need for product validation. What sets Igor apart is how he creates a safe, judgment-free space for founders to voice their concerns. He is incredibly generous with his time and truly invested in helping others succeed. For anyone looking for not just exceptional technical advisors but all-around advisors who have your best interests at heart, FastCTO should be your first stop.

The FastCTO team has been awesome since Day 1. Our CTO dove deep into our current systems and products to help align us as a team internally alongside FastCTO's developer and software consultants, and continue our path towards total synchronization of all our products, from codebase to cloud platforms. As a result, we have both improved already some of our current products, built new ones, and moved to better technical practices for the type of data we process & disseminate. Previous companies were more involved with up-front planning, gave us the schematics, but not the tools nor resources to implement. FastCTO is with us every step of the way and actively involved throughout the process, from planning to deployment & continuing maintenance. The engineers we have hired from FastCTO are competent, proficient, and hard-workers. They are true, valued members of our development team, and not simply "consultants". I would recommend FastCTO for any company who was not originally a tech-based company looking to keep up with the ever increasing demands of a tech world at an incredibly affordable price with an ethical business model. While FastCTO may not always have all the answers at the drop of a dime, they have been fabulous connecting us with other resources or searching for the appropriate consultant with the necessary background to help solve a niche problem. Not to mention team members take it as a learning experience and work to become experts on that topic - a true win-win.

We first worked with FastCTO in the early days at Compt. I had them come in and do a full tech review to ensure we were architecting the platform in a scalable way. From there we leveraged their team to coach and support our growing engineering team as they upskilled. They have been instrumental in supporting our growth over time. I highly recommend them for new companies, scaling companies, or just anyone who needs some additional coaching or guidance!

FastCTO's Ukrainian dev program is a game-changer. The junior engineers I've had the privilege of hiring are smart and ambitious. It’s a pleasure to watch them grow and learn on the job, and I greatly appreciate all we've been able to accomplish together.

At Venture Lane we support a network of 1,000+ startups, including a portfolio of investments, and ultimately measure our success on theirs. This means that we look for partners that we can count on, and FastCTO has proven to be one of the best. They’ve worked with a large number of the startups in our B2B tech community, and the feedback has been consistently and overwhelmingly positive. We’re very intentional in selecting just one service provider in each category as the go-to for our startups. We focus on finding partners who are genuinely committed to founder success and have a community-oriented approach, and FastCTO made that decision easy. Igor, Charlie, Tanya, and Olha are a fantastic team. They spend a lot of their time getting to know the founders in our network, giving no-strings-attached advice, and consistently delivering top-notch results. Their network of in-house CTOs is also well-regarded, giving our founders access to incredible talent. What makes FastCTO stand out is their dedication to building real, long-term relationships based on trust. Unlike others in the industry who chase high margins and quick wins, FastCTO focuses on creating value while keeping their margins low, which ensures startups get the best service without cutting corners. When early-stage startups tell me about their product development plans, I can’t help but rave about FastCTO—and usually, they get on board too once they see the difference for themselves. When managing a community and portfolio of startups, results matter most, but it sure is a bonus that working with FastCTO is also a genuinely enjoyable experience. They bring enthusiasm and energy to every interaction, making the entire process a positive one. If you’re looking for a partner who’s fully invested in helping startups succeed, FastCTO is the clear choice and an integral part of supporting our ecosystem.

I chatted with Igor during a CTO on the Run event he held while he trained in Barcelona. It was a great conversation where I learned from him, and the fellow attendee. The length and setting of the conversation led to a deeper dive into concepts than I would otherwise expect. It was honestly quite good, and I've mentioned it to at least 10 people since then. The running & talking format is particular good for longer strategic discussions where screens aren't involved. BTW - He stopped a few times to share views of city - it was a treat. Thanks!

I learned more in 20 minutes talking to Igor than in 2 weeks talking to everyone else in the industry. Super helpful and saved me a lot of time and money.

I want to start by saying that FastCTO truly transformed my startup. We initially built our MVP using an offshore dev shop, and while it "worked," it felt like it was held together with duct tape and band-aids. From the moment we began working with Igor and his team, the energy shifted, and our product reflected that change. They seamlessly integrated into our team and became trusted partners. As a non-technical founder, I’ve appreciated how our CTO has gone above and beyond—not only to keep things running smoothly but also to take the time to teach me along the way. I can't thank them enough for all their hard work and dedication!

As a small startup in the medical software industry, it's tough to adapt quickly to software engineering needs. Hiring is a lot of work, so once you determine that you need another software engineer, it can be daunting to do the hiring yourself. Then you need to plan for 1-3 months of searching, scheduling, interviewing, etc. With FastCTO, it's been a huge time-saver for our small team. Out of the 3 full-time software/ML engineer hires, we interviewed a total of 3 people. FastCTO does the hard work of finding you the best person for your role and budget, so by the time they share a candidate with you, they are highly likely to be a good fit for your team. With the time we've saved, we have been able to focus on planning and executing on our software. If you are short on time but still want high quality engineering team members, I highly recommend working with FastCTO.

Vlada has been an invaluable asset to our team, stepping up to tackle anything we throw her way. She quickly contributed to backend API updates, frontend changes on the dashboard, and enhancements to the marketing website on Webflow. She has seamlessly taken over primary QA responsibilities, demonstrating a keen eye for identifying issues. Whether it's manual or automated testing, Vlada excels in both. Beyond finding bugs, she consistently offers thoughtful suggestions to improve the user experience from a customer perspective. Her strong soft skills and readiness to help whenever needed make her a standout team member.

I enjoyed the call with Igor. The CTO on run is a great initiative and I really appreciated it. Thanks.

FastCTO was incredibly supportive in our search for a new Head of Engineering. They scoured their network and continuously refined the ideal candidate profile based on feedback from our team. Would absolutely recommend, especially vs a traditional staffing or recruitment agency!

Igor just taught me a valuable lesson: simplicity often outshines grandeur. A good idea, when effectively communicated, can surpass even the most intricate concepts. Like a well-crafted symphony—each note precisely placed, resonating with purpose. Igor’s guidance crystallized my vision. In just one hour, he unraveled complexities that would have otherwise consumed months of build and capital. Now, armed with newfound clarity, I can reallocate my time toward a more incisive marketing strategy. Thank you, Igor, for your invaluable insights. I’m already excited to reserve a spot for our next session as soon as more dates are posted :)

I had a great conversation during FastCTO's CTO On The Run call! I left the call with new solutions and action items for a couple of problems my company is facing. I can safely say that FastCTO saved me precious time that I could've spent thinking about the wrong or lesser solutions.

Our company was introduced to FastCTO at a networking event. I was skeptical at first, as it's tough to find quality consultants. The early conversations went very smoothly and easily. After understanding our specific needs, FastCTO team identified and delivered several candidates of impressive quality within a couple of weeks. After hiring the favored candidate, we found him very competent, knowledgeable, hard-working, and with excellent work ethics. Thank you, FastCTO team!

I cannot recommend FastCTO highly enough. We used FastCTO to help us transition away from our original, US-based software development team. Igor provided several CTO candidates for us to interview, all of which were capable, but one had experience that was a perfect fit for us. This CTO has been instrumental in quarterbacking our technological roadmap and managing the software development team that is doing the actual coding. He was also able to identify several issues with our code that would have limited its scalability. I would recommend FastCTO to anyone that is looking for a change from their existing software team and wanting to have a fresh set of eyes review the code and roadmap.

I had the pleasure of engaging with FastCTO as part of the due diligence process for a Private Equity transaction. The project had many challenges - from a tight timeline to very limited information available. Despite these headwinds, the team was able to provide a thorough review that ended up being critical to our investment decision. What really stood out to me was their outstanding communication throughout the entire process, ensuring that we were informed and up-to-date every step of the way. The team also took the time to explain complex concerns in a digestible format. Additionally, the turnaround time of the high quality materials was incredibly fast, which allowed us to move forward with confidence and speed. I would highly recommend the FastCTO team to anyone in need of thorough due diligence support and analysis.

As a client of FastCTO, I have been thoroughly impressed with their technical expertise and their ability to make well-informed decisions that have greatly benefited our business. They took the time to understand our business model and our unique requirements, and used that knowledge to help us make informed and effective technical choices. I was impressed on how some of the key decisions we made either saved us so much time or prevented us from going down a complicated path, while educating us along the way.

Working with the FastCTO team has been absolutely fantastic. As our business has evolved, we have been able to build the team easily, and adjust our team to meet our latest development needs. I would not be able to manage the developers, designers, QA, etc. without the help of our CTO. We could never afford a full-time CTO at this phase. I sincerely think that FastCTO has been our strongest partner and without Igor and team, we wouldn't be the business we are today. Thank you to FastCTO for helping us take our vision and make it reality, actually even better than reality!

FastCTO is fantastic. Igor and his team have helped us build out our platform from nothing. We hope to see continued growth from our partnership, as our app goes live this month!

Working with the FastCTO team has been an invaluable experience for our organization’s growth. Their ability to quickly understand our previous tech stack to create a new roadmap to enhance our product offerings is unmatched. Each member of our developer team brings a wealth of experience and marries quality with meeting customer expectations. I would recommend FastCTO to organizations looking for a partner that values achieving the results that matter. We could not have asked for a better strategic leader than our FastCTO.

I can’t heap enough praise on Yan! He is easily the best devops engineer I've ever worked with! I've worked with some amazing devops engineers over my nearly 30 years in tech, and I’m not exaggerating when I say Yan is the best I’ve worked with! He accomplished what we were previously told was impossible, and he did it with determined resourcefulness! Anyone who gets to work with Yan is going to be delighted with the experience!
