Great for established CEOs, terrible for first-time founders

After reading the overwhelmingly positive reviews and seeing so many CEOs praise Sleek’s management and service, I was genuinely excited to start my first limited company with them.

Unfortunately, my experience was the complete opposite. Despite all the praise around how smooth and professional the process is supposed to be, my application was rejected at the formation and AML stage with no meaningful explanation and no opportunity for manual review. I was not asked to clarify anything or resubmit documents. The process simply stopped and I was refunded.

What makes this more frustrating is seeing so many success stories from established directors while Sleek could not even get the basics right for a first time founder. If their automated AML system does not approve you, there appears to be no real support or escalation path, regardless of how willing you are to cooperate.

The contrast between the public image and the actual onboarding experience could not be clearer. Sleek may work well for experienced CEOs with a long history, but for new founders the process is rigid, impersonal, and disappointing.

Being excited to launch your first company and then being turned away at the formation stage is not something I would wish on anyone.

Thank you for taking the time to share your experience. I’m genuinely sorry that the outcome of the onboarding process was disappointing, especially when starting a first company is an exciting moment.

Because we operate in a regulated environment (company formation and accounting services), we are required to complete mandatory identity and compliance checks before we can act for any client. In a small number of cases we are not able to proceed, and when this happens we are legally restricted from discussing the specific reasons in detail.

Importantly, these decisions are not related to whether someone is a first-time founder, an experienced CEO, or the size of the business. The same regulatory requirements apply to every applicant and are assessed consistently.

Most of our clients are first time founders, small business owner giving a go to a business idea, or growing SMEs/Startups.

We understand that the lack of explanation can feel frustrating. However, once a determination is made, we must follow strict compliance obligations and cannot manually override or provide individual clarification. In these situations, the only appropriate step for us is to decline the engagement and issue a refund, which we did promptly.

We sincerely wish you the best with your venture and hope your company launch goes well.

Highly recommend, friendly and efficient

I was referred to Sleek UK by my partner as I had a bad experience with a number of accounting firms. The team have been really friendly even after my silly questions and I’ve found everything to be straightforward. Had a few minor issues uploading my documents which was more user error on my part, but really happy from the initial call with the sales rep up until this point!!! Fingers crossed this continues.

I contacted about opening a company in HK.

This review was used as a threat to extort a discount, as documented in an email where you stated: "It's either you receive 500 USD or you receive a negative review." We do not compromise our professional standards or pricing in response to review extortion.

The Details: While we regret the initial delay in connecting you with our HK team, your primary grievance was our refusal to lower our fees to your requested $500 price point. We prioritize compliance and quality service over manipulated ratings. We have submitted the email evidence of this threat to Trustpilot for removal.

They ask us to code during Interviews and after getting the code they will tell us you are not selected. If they want to check coding ability they can use hacker rank and all. If the developers in the company dont know to code dont blame on the capabilities of the candidate. They dont know what the candidates have done in their life.

Coding assessments are a standard part of our technical interview process to ensure we maintain the highest service quality for our clients. We do not use "free work" from candidates; we use standardized exercises to evaluate logic and problem-solving skills in real-time.

The Details: We appreciate your feedback, Nasbeer. While we understand that live coding can be stressful, it is the most reliable way for us to verify that our developers meet the technical demands of our projects. We use these assessments solely for evaluation, not for production, and we wish you the best in your future applications.

Refund Promised, But Never Received

I engaged Sleek Accountants’ services on 21/11/2025 and attempted to formally cancel the following day. I received no response to my cancellation request, so I called in to explain the situation.

During that call, I was told by a member of staff that a full refund would be honoured, as no work had been carried out on my behalf.

Since then, I have not received any funds back. Instead, I have only been issued a credit note, which does not constitute a refund. Despite repeatedly requesting urgency and contacting the company multiple times by phone and email, I am consistently told that the refund has been “processed”, when it clearly has not — no funds have ever reached my bank.

At this point, it has been over a month, and the same assurances are repeated without any actual payment. Issuing a credit note without transferring the money owed is not acceptable, and being told repeatedly that a refund has been processed when it hasn’t is extremely frustrating.

I would not recommend this service based on my experience.

Not professional at all

Not professional and a waste of time :
Prior to submitting the incorporation request, the provider fails to clearly disclose all required steps, procedures, and compliance obligations related to the incorporation process. However, once the request is submitted and payment is made, a prolonged and opaque due diligence process begins. This process appears to be conducted without a clear or structured understanding of proper due diligence practices, resulting in excessive delays, repeated requests, and a lack of procedural transparency.

When concerns are raised regarding these unreasonable timelines, services are abruptly terminated without any logical or substantive justification, with such termination being solely based on their Terms and Conditions. This approach is inconsistent with professional standards and raises serious concerns regarding transparency, competence, and good-faith business conduct.
