This tool has really simplified our onboarding process. We find ourselves using it frequently! Review collected by and hosted on G2.com.

There is no downside, however it would be awesome to keep adding features or being able to completely white label your domain using your branded domain. Review collected by and hosted on G2.com.

I love that Leadsie just works, and every new feature they roll out lifts a weight off our shoulders. They often implement features faster than we can think to use them. They are quick to adapt to updates from Facebook (Meta)'s API and others, eliminating the need for us to worry about these changes.

They are always available for questions and new use cases, constantly adding new functions without us even having to ask (Ok, we do ask sometimes but they listen!)

Their API and Webhook have allowed us to integrate Leadsie directly into our systems, eliminating manual errors and time-costs associated with transferring data from Meta to our systems.

We don’t have to worry about changes in Meta or others when they change their user interfaces, authorization APIs, or access policies. We simply generate a link with the permissions we need to get in Leadsie, send the link, and their webhook alerts our systems as soon as our users grant us access to their pages and assets.

We use this daily and it´s been a big time saver.

It just works! Review collected by and hosted on G2.com.

So far, there is nothing I don’t like.

The only potential downside could be the feeling that we're sometimes moving slowly on some things. Leadsie has already implemented TikTok’s authorization API, for example, but we have yet to acquire clients seeking that service. However, we are working on it.

So easy, so simple, looks good enough to send a Creator Review collected by and hosted on G2.com.

Wish I could whitelabel it from a specific client brand even though it goes to my business manager Review collected by and hosted on G2.com.

What I appreciate most is how easy it is to connect ad accounts—just a single click and everything is set up. This level of convenience really streamlines the process. Review collected by and hosted on G2.com.

Overall I really like Leadsie. The only area I see room for improvement is simplifying a few steps in the workflow. Streamlining those would make an already great tool even more efficient. Review collected by and hosted on G2.com.

Leadsie is an absolute game changer for agency onboarding. It takes all the hassle out of connecting to client ad accounts, pages, and other assets. The process is straightforward for clients – even those who aren’t tech-savvy – and it saves our team a huge amount of back-and-forth. It’s seamlessly integrated into our onboarding flow and has become an essential part of our tech stack. Review collected by and hosted on G2.com.

The only minor issue is the UI, which could be a bit more intuitive in places. There’s also the occasional extra step for clients, such as needing to log in to Meta Business Suite to assign Instagram assets – but to be fair, that’s more of a Meta limitation than Leadsie’s fault. Overall, there’s very little to fault. Review collected by and hosted on G2.com.

It’s the only tool we use where the client has no idea how powerful it is, they just click a link, and everything’s connected. No more chasing logins, 2FA codes, or “can you try it from your desktop?” nonsense. It’s so seamless, it’s become the handover point between our sales and delivery.

Honestly, the only frustration is when a client still manages to mess up the process, which is rare, but it happens. Would love a clearer fallback for when clients decline permissions or use the wrong email. But that’s more a people issue than a product one. Review collected by and hosted on G2.com.

Getting access to our clients’ accounts used to be a major time killer – especially for Meta, Google, or TikTok. It often took days and was prone to errors. Since we started using Leadsie, this process has become simple, fast, and reliable. Clients just click a link, and Leadsie takes care of the rest. Highly recommended for any agency looking to save time and present a more professional onboarding experience. Review collected by and hosted on G2.com.

While Leadsie has streamlined our access workflows significantly, there are still a couple of limitations. We’re currently missing an integration for Microsoft Ads, which would make the tool even more complete. Also, access to Meta ad accounts occasionally doesn’t go through – though we understand this is more of a Meta platform issue than a Leadsie one... Review collected by and hosted on G2.com.

Really useful app, shortcuts a lot of work that used to be manual. Makes quick work of some of the platforms where sharing access can be tricky e.g. Meta Biz manager. Review collected by and hosted on G2.com.

Doesn't fully support all advertising platforms yet. Review collected by and hosted on G2.com.

Honestly, the best part about Leadsie is how it just makes everything smoother for us and our clients. It cuts out that crazy back-and-forth email ping-pong trying to get access to client accounts, chasing logins or resetting passwords. This saves us so much hassle and lets us focus on selling instead of admin headaches. It has been a nice surprise "wow" moment for a number of clients I speak to, impressed at how intuitive and straightforward it is. Some even thanked me for making the process so easy for them!

Our onboarding is equally streamlined. Clients can easily upgrade access to everything we need in just a few clicks.

It's exciting to see the list of integrated platforms growing, and the customer support is first class!

If you want to impress your clients by saving them (and yourself) time and hassle. Get Leadsie. We haven't looked back. Review collected by and hosted on G2.com.

Few downsides. Sometimes I get caught out when I don't realise a token has expired and the client can not share access. Review collected by and hosted on G2.com.

’ve been running agencies for over 25 years, and I can say without hesitation: Leadsie is the single most impactful third-party tool I’ve ever implemented. Before Leadsie, client onboarding could drag out for days—or even weeks—with back-and-forth emails, login requests, and confusion.

With Leadsie, we onboard clients in minutes. Not only has it saved us countless hours, it has also led to happier clients, longer retention, and a smoother experience across the board. That alone would be worth it—but the downstream impact on our ROAS, scalability, and operational efficiency is massive.

If you're not using Leadsie, you're basically running a caveman operation. It’s that essential. Review collected by and hosted on G2.com.

I hope they add ALL the channels and platforms, because it's so easy for the platforms they support today. Review collected by and hosted on G2.com.
