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.

Big thanks to K21 Academy for fueling my AI/ML journey!
The instructors made even the most complex ML and Generative AI topics crystal clear with hands-on labs and real-world use cases.
But 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 level of learner-first commitment is rare and inspiring.
Also, shout-out to their support team—always prompt and helpful.
Highly recommend K21 Academy to anyone serious about mastering AI, ML, and Cloud from both technical and leadership perspectives.

I began my AI transformation journey with a mix of caution and nervousness. Starting with small steps through K21, I quickly gained confidence and soon felt like an emerging expert in the AI space. I look forward to completing this journey and becoming a true champion with K21.

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.

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 !!

SCAM ALERT: AVOID THIS "ACADEMY"
Do not pay them—they are highly selective about who they target for charges. My experience was a series of problems: classes were constantly being changed, and when I encountered an issue, a 'scammer' named Atul advised me to speak to the offline. No guts to handle situation in the class.Every time they simply plugged to some on going class which was irrelevant to me
After the escalation they initially agreed to a repayment after six months, but I received nothing, and there was zero follow-up for subsequent classes. They cleverly handling refund policy to my banker's attempts to help. They offered me three installment payments, yet I was never placed in a class until the total money was collected. Their clear intention is to take your money, not to teach you.
Be very careful. Look for free, quality courses online instead. Beware of the +44 international numbers; they seem focused on targeting US funds. I am not letting this go.
My follow up response on your reply - 5 Dec 2025
The contrast between your pre-payment communication and your post-issue support is unacceptable.
When you were collecting funds/enrollment , your team contacted me every single day. Now that I have reported a significant failure—specifically, your failure to conduct basic training—all communication has stopped, and my direct requests for a refund are completely ignored.
I have an open service ticket and all supporting evidence, including a relevant WhatsApp audio recording from Atul. I have seen reviews indicating a history of refusing refunds, but I have fulfilled my part of the agreement and have not moved out as alleged. What is preventing you from processing the refund for the service you failed to deliver?
I am prepared to upload all documentation if the platform allows it. I expect an immediate response regarding my refund.
I am concerned that you are actively hiding or downplaying similar negative reviews through the use of questionable or potentially paid positive feedback. This lack of transparency is unacceptable, and I require the immediate return of my funds due to service failure.

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

Poor and rude customer service. Money back guarantee is a big lie, job support big lie, 24/7 customer support big lie, they don't even if you're understanding the course or not , just running off , reading through to finishoff , the course provided will get you only job in India. Waste of time and money.

I just wanted to say a big thank you to K21Academy. I signed up last year with the intention of completing my training within that time frame. But due to the birth of my new born, I was unable to set time aside to peruse my studies. After speaking to management and their Customer service team I was given an extension tomorrow my training. Apart from being grateful for the extension, K21Academy is a well recognised platform for all aspects/fields of IT training. I highly recommend them.

Hi I am taking AWS AI/ML course with K21academy. The live sessions are really good. The trainer makes sure to answer all our doubts. Concepts are repeated if not understood and there is alot of material to study and practice which is the best part. Recorded sessions are available immediately with relevant labs to do. Im enjoying learning the course. I am yet to take the job assistance which u believe will also be great.

I only wish I had seen the reviews before applying. It would have saved me from this experience.
Terrible experience with this company. They mislead people, exploit their dreams, and create false hopes. Please avoid at all costs!
I plan to share my experience more widely soon with facts so others are aware and can avoid falling into the same trap.
