Leadsie Reviews & Product Details

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.

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.

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.

The simplicity. Leadsie has removed all the friction from onboarding clients. Instead of lengthy email chains or messy how to guides, I just send a Leadsie link and clients can securely share access to their Meta, Google, or TikTok assets in seconds. It's fast, professional, and makes our agency look super organized. Review collected by and hosted on G2.com.

Honestly, not much. If I had to nitpick, I'd say I’d love to see even more integrations in the future, but they’re already expanding rapidly. Review collected by and hosted on G2.com.

They reached out to us years ago when they were just getting started and offered the tool for us to test. Within days, I knew this was it. No question, it’s been a core part of our agency’s toolkit ever since, and we’ll happily stay with them for the long run. Once you make the switch, there’s simply no easier way to get accounts connected in seconds. Review collected by and hosted on G2.com.

Nothing, they continually are pushing boundaries to make more connections - simplified. Review collected by and hosted on G2.com.

Leadsie has been an absolute game changer for our agency's client onboarding process. The platform's ability to simplify access to clients’ Meta, Google, and TikTok accounts with just a single, secure link has saved us countless hours of back and forth emails and confusing instructions. Review collected by and hosted on G2.com.

What used to take days chasing logins, guiding clients through complex steps, or dealing with Meta’s ever changing UI, now happens in minutes. Our clients love how seamless and professional the process feels, which sets a fantastic tone for our relationship from the start. Review collected by and hosted on G2.com.

Leadsie eliminates the back-and-forth nonsense of requesting access to client assets. Instead of walking clients through complex instructions, I just send them a link. They click, approve, done. It streamlines onboarding and makes us look more professional and organized. Review collected by and hosted on G2.com.

The ability to request access to Google Ads, GA4, Search Console, Meta, and more in one shot is a game changer. Clients don’t need to fumble through settings—they just log in and Leadsie handles the rest. It also tracks status, so I know exactly who has or hasn’t completed the request.
