K21 Academy provides great support
K21 Academy provides exceptional support throughout the learning journey. I received great technical assistance from Sahid, who was always responsive and helped clarify my doubts with clear explanations. The mentors offer strong technical guidance and ensure learners feel supported at every step. The courses are hands‑on, practical, and beginner‑friendly, covering in‑demand skills like Cloud, AI/ML, and DevOps through real‑world labs and projects. Additionally, the career-focused support such as mock interviews and job preparation sessions helps learners gain confidence and become truly job-ready.

Joining K21 Academy is one of the best IT Teaching Platforms
Joining the Azure Job Oriented course at K21 Academy is one of the best decisions I made this 2026. My only regret is that I didn’t find K21Academy sooner but that is okay, because even now I am happy and feeling confident with the learning process because k21 Academy has quite an elaborate warehouse of learning resources, with step by step guides on hands on and projects on real world scenarios for practice plus an amazing team of trainers/instructors who take their time to explain concepts and make sure no trainee leaves any live sessions with any queries unanswered. The support system is well structured. There is constant followup from the team , to check on the progress of each trainee. Every individual here supports learners in achieving their goals. It is hard to single people out, but I must mention Manish,Richa, Malika, Gracy and others along with Atul Kumar, who have contacted me on how I am doing with my studies and if I have any queries and also the importance of updating my resume and linkedIn profile and start applying for jobs even if I am still studying.
I am confident that I will land a great position very soon, and this will be thanks to the entire team at K21. A big shout out to the entire team @ K21 Academy

DP-100 exam passed
Happy to share that I’ve cleared the DP‑100: Azure Data Scientist Associate exam. This is another big step in my AI journey, and I want to thank K21 Academy for helping me get here.
K21 has been a solid starting point for me in AI. The explanations were clear, the structure was easy to follow, and the hands‑on labs made all the difference. Working through real Azure ML scenarios — training models, creating pipelines, deploying them — helped me build confidence for both the exam and real projects.
The support, the community, and the practical approach at K21 played a huge role in helping me stay consistent and finally clear this certification.

Dear Yussuph,
We take every review seriously. Let me properly outline the history of your case for transparency, so everyone can see the details from day one:
January 9th: You purchased our course, accepting all terms and conditions.
January 10th: We shared the proper pathway and access with you via our official support channel, but we did not receive any response.
January 12th: We shared the necessary job support materials with you via our support channel, but again, there was no response from you.
January 13th: You mentioned that you did not want to continue, and we tried to reach out. After that, you became unresponsive.
January 15th: Without connecting with us to discuss the refund policy or explore potential solutions, you directly raised the dispute under the wrong category, leading the bank to hold your transaction for investigation. On the same day, we informed you about the dispute, but we did not receive a response.
The bank took over 25 days to thoroughly investigate your case, gathering all necessary details, reviewing our website, and examining the terms and conditions, which clearly demonstrate the transparency of our policies. Based on this investigation, the bank closed the dispute in our favor.
We are still committed to honoring our refund policy. To clarify, our refund policy allows you to request a refund within 6 months of purchase, provided you show that the program hasn’t provided value. This means that if you complete the work, finish the labs, and demonstrate progress, we will assess your results. If the program hasn’t met your expectations, we can then offer a refund.
K21 Academy has been in the market for over a decade, supporting over 45,000 professionals globally and helping learners transition into Cloud, DevOps, AI, and other in-demand technology roles. Our results are reflected in numerous verified success stories and video testimonials from learners who actively engage with the program. You can view some of these success stories here:
👉 https://k21academy.com/success-stories/
We are still open to helping you and providing support, and we encourage you to follow the policy to continue progressing with the program.
Sincerely,
K21Academy
K21Academy's been a great experience
Love K21Academy. The instructors are great, training material relevant to what is needed in the market, and is very thorough, but above all, the job search guidance is spot on. You just have to make sure to follow the guidance. Trust the process and you'd be surprised by what you can achieve.

Game Changer in AI/ML world
Big thanks to K21 Academy for powering my AI/ML journey!
The sessions made even complex ML and Generative AI topics easy to grasp through hands-on labs and real-world use cases.
Special shout-outs to Sahid for his deep knowledge and professionalism in guiding students, and Alman from the support team for his prompt and friendly help!
The real highlight? When I asked Atul (Founder)about practical GenAI and Agentic AI use cases for Product Owners, he didn’t just answer—
👉 He launched two new, architecture-focused courses!
That kind of learner-first dedication is truly inspiring.
Highly recommend K21 Academy to anyone serious about mastering AI, ML, and Cloud from both technical and leadership perspectives.

Deceptive, Fake “Live” Webinar & Manipulative Sales Tac
Do NOT trust a single word K21Academy says.
I signed up for their so-called “FREE LIVE Masterclass” after seeing nonstop ads on Instagram, Facebook, and other social media platforms. They explicitly advertise it as a live session with interaction and Q&A.
That is a complete lie.
The moment I joined, it was obvious that the entire session was a pre-recorded video playing on a loop. There was nothing live about it.
What makes this worse:
• The “live chat” is clearly fake or bot-driven
• Messages look scripted and timed
• When you try to ask a real question, you’re either ignored or get a generic, automated response
• No actual trainer responds in real time
This is not just misleading — it’s insulting to people’s intelligence.
If a company is willing to lie so blatantly about something as basic as whether a session is live, it seriously makes you question:
• The honesty of their course content
• The credibility of their success stories
• The truth behind their so-called job guarantees
By the end, it becomes obvious what this really is:
A 90-minute sales pitch disguised as a “masterclass”, filled with fake urgency, countdown timers, and pressure tactics to make you spend thousands of pounds/dollars.
Atul Kumar and his team may be marketing geniuses, but they are not behaving like educators. Education starts with trust — and this experience destroys it in the first interaction itself.
There is absolutely nothing wrong with pre-recorded content. The problem is lying about it.
Final advice to anyone considering K21Academy:
Go in knowing this is not live, not transparent, and heavily sales-driven. Better yet, stay far away and look for platforms that respect your time and intelligence.
Very disappointing and dishonest first impression.

Hello,
Thank you for sharing your feedback. We have carefully reviewed our internal records but were unable to locate any enrollment, payment, or participation details matching your name or the context described in your review.
Additionally, the language and framing of the feedback do not align with typical learner experiences we receive and, unfortunately, resemble patterns commonly seen in competitor-driven or non-customer commentary rather than genuine user feedback.
We strongly encourage transparency and welcome authentic reviews from verified learners. If you have genuinely enrolled with K21Academy, we request you to contact us directly with your registered email ID or order details so we can investigate and address your concerns appropriately.
Until then, we remain committed to supporting our real learners and maintaining the integrity of our platform.

I worked as their sales associate so if you are a customer who's reading this and on the verge of wasting your money, STOP AND READ THIS....
I worked as a Sales Associate with this company. My role was to speak with innocent learners who were looking for career growth, first understand their pain points, and then manipulate those pain points to convince them to pay a hefty amount—around $4,800—for a poor-quality online training program taught by underqualified professionals. The company claims that they will place you in a $200k job role in Cloud/AI-ML within 3–4 months and that your money will be refunded if you don’t get results. But in reality, there is no refund at all. It is a clear instruction from the CEO, Atul Kumar, that no refunds should be given—not even the $200 booking amount. The company operates on a WFH model, and the CEO dictates everything from London. They hire capable sales professionals and then ruin their careers. Employees are removed without notice by simply disabling their Google accounts and removing them from WhatsApp groups. They exploit their employees and put extreme pressure on them to generate revenue at any cost. I had a power cut issue in my area, and although I informed the company via email, it was delayed by one hour due to the outage. For this, the so-called CEO fired me immediately. This alone is enough to understand what kind of company this is. The CEO believes he can do anything because he is making huge money sitting in the UK, while his hardworking inside sales associates stay awake all night to generate revenue for him. If any sales associate from K21 Academy who worked with me is reading this—please resign and find a better company. Do not waste your valuable time here. Atul does not care about your career or the effort you are putting in. I feel sorry for myself and for all the learners I onboarded during my 7 months of tenure at this company. I generated an overall revenue of $93,000 in just 6 months. My advice to every learner reading this: DO NOT FALL FOR THIS SCAM COMPANY. YOU WILL WASTE YOUR HARD-EARNED MONEY.
they have not paid my pending incentives and 1 month of salary which they are legally bound to pay since they terminated me.
CEO ATUL KUMAR ( +44-7352344266) HAS BLOCKED MY NUMBER AFTER THREATENING ME ON CALL THAT HE WILL COME AND BEAT ME IN GURUGRAM. I HAVE ALL THE PROOFS WITH ME.
I FEEL INTIMIDATED WITH THE WAY OF HIS COMMUNICATION ON THE LAST CALL. THIS GUY THINKS HE CAN DO ANYTHING BECAUSE HE HAS MONEY !! THE MONEY HE GATHERED BY SCAMMING AT LEAST 4000-5000 LEARNERS !!

Dear Salil,
We are aware of the allegations you have recently made regarding your experience working with our organisation.
As employees, we believe in maintaining transparency, professionalism, and fairness, and therefore, we would like to present the facts from the company’s perspective.
First things first, K21Academy is committed to providing results to all its learners, and the fact that we are currently serving more than 45,000+ trainees and maintaining a 4.8-star rating shows the quality and the results we deliver.
All our Success Stories can be accessed here: https://k21academy.com/success-stories/
Having said that, the Refund policy you mention is conditional and requires the customers to work to get results, and the customer is mandated to read the policy properly before enrolling on any of our programs. (You also attended sales training covering the same and were asked to communicate this in writing over email. Check the sample mail below.
As for clients who pay the booking amount, they pay the booking amount to reserve a seat in the program, and they are clearly told that it is a non-refundable booking fee for blocking the seat for them and the same is communicated to them via email before charging the booking fee
As for you, from the day you joined, the company extended full flexibility and support expected in a work-from-home environment. However, throughout your tenure, there were consistent concerns raised by multiple managers regarding your work ethic, communication practices, and adherence to basic operational processes.
Despite repeated reminders and guidance, the following issues continued to occur:
Frequent non-attendance or delayed attendance in important team meetings.
Repeated failure to submit mandatory End-of-Day (EOD) and End-of-Week (EOW) reports.
Lack of clarity about your start time, break time, and log-out time, even after multiple reminders.
Unresponsiveness during working hours requires your managers to reach out repeatedly to confirm your availability.
As an organisation, we made several efforts to support your performance and well-being:
Your reporting structure was changed multiple times to give you a more comfortable and supportive supervisory environment.
We approved all your medical leaves and provided flexibility whenever you requested it.
You were supposed to join from 1st December, but you joined from 2nd, and we understand delays happen, and we welcomed you back to the organisation.
We unfortunately had to make the decision to let you go when we saw that just after 2 days, you again faced an electricity issue, which you failed to inform till your start time and disclosed it only after we reached out to you after waiting for you for almost an hour.
Our decisions have never been based on any personal bias.
We maintain a strict policy of equal respect, equal opportunity, and equal treatment for all employees.
Every individual working here is expected to fulfil standard professional responsibilities, including maintaining communication, completing mandatory reports, and giving eight hours of accountable work requirements that apply uniformly across the organisation.
On your last working day as well, you remained unresponsive and did not inform your manager about your unavailability.
This was not an isolated incident; it was part of a long pattern of similar behaviour.
This decision was not a reaction to a single day’s event but the outcome of several months of documented concerns and discussions.
We remain committed to integrity, fairness, and the well-being of every employee who is part of our organisation.

Hey Naga,
We tried searching for your details in our system but couldn’t locate your profile. If you are an enrolled trainee, please share your registered email so we can assist you personally.
Regarding the program pricing — our courses are indeed premium, and the reason is simple: we provide far more value, support, and real outcomes than standard low-cost platforms.
Just like every four-wheeler can be called a car, but a Rolls-Royce stands apart — not because it looks different, but because of the quality, experience, and commitment behind it.
That is exactly what reflects in our training as well.
We’re trusted by 45,000+ trainees globally because we consistently deliver:
Expert-led, real-time mentorship
Hands-on labs and project support
A structured step-by-step learning path
Dedicated success coaches
Interview preparation & job assistance
Reliable, human support whenever needed
Please Check our Success Stories- https://k21academy.com/success-stories/
These are the reasons we have countless genuine success stories and continue to grow every day.
If you need help or have any concerns, we’re here for you — just let us know.

Dear K21 Academy Team,
Dear K21 Academy Team,
I wanted to take a moment to express my sincere gratitude for the outstanding support I’ve received from the K21 Academy community since 2022 starting from my Cloud DevOps Engineer journey and now transitioning into Data Engineering, which has been the most exciting and rewarding phase so far.
Recently, while preparing for my Azure Data Fundamentals Exam, I reached out for help and I’m deeply thankful to Richa and Shubhangi (please excuse the earlier misspelling of your name in my first post!) for going above and beyond to share their support, configuration steps, and encouragement, which truly boosted my confidence.
And of course, a big thanks goes to Aman -the GOAT -for always bringing clarity, energy, and motivation to every session.
The passion, expertise, and consistency your team brings to every session are truly inspiring. I’m genuinely proud to be part of the K21 Academy community and thankful for how much I’ve grown through your guidance and mentorship.
Warm regards,
Bill Eson
