Leadsie: Making Onboarding Slick Since 2020 

Our mission is to eliminate the onboarding headache forever. Thousands of agencies use Leadsie to seamlessly onboard their clients.

Our Story

You spoke. We listened.  

Leadsie started as a lockdown project when we (Robert and Johannes) found ourselves with a little extra time on our hands. 

We wanted to build a tool that marketing agencies truly needed - not just mimic other tools out there that didn’t solve your most pressing problems.

We bounced a few ideas around and built a Facebook audit tool. After showing our prototype to dozens of agency owners, it turned out our hypothesis about what you wanted or needed wasn't correct…🙃

Back to the drawing board. 

After hundreds of conversations with agency owners, we found the most pressing pain point you were experiencing: getting access to clients’ marketing assets and accounts. 

We got to work, building the first-ever tool to make getting asset access painless. We wanted agency owners to say bye to their onboarding headaches. Forever. And so, the current version of Leadsie was born.

We’re in it for the long run. 

Our business is driven by what agencies actually need - not what we think they need. We learned not to make assumptions early on 😉. 

All new features and innovations are brought to life after listening to your most pressing needs. 

Our clients are the only people we answer to and we consistently reinvest into the business so we can build the features you need

Sure, sometimes we get things wrong, but when you tell us how to put it right, we’re there for you. We pride ourselves on customer experience, and you can actually get hold of us for a chat when you need to.

Who are team Leadsie?

We’re a hands-on, small but mighty, steadily growing team. We love solving our customers’ problems so we can make Leadsie as useful as possible.

Oh yeah, did we mention we’re such a tight-knit team that back in 2021, we had a double Leadsie wedding where both co-founders spontaneously married their girlfriends on the same weekend? 😂

Weird or quirky?! We’ll let you decide on that one…


Here's how we do things

Leadsie began after talking to hundreds of marketing agencies. We wanted to build the tool you needed most.

Customer Focus

Chatting to our customers is still how we roll. Johannes and Robert regularly take time to get direct feedback from you.


Leadsie is 100% bootstrapped since day one. We have no investors or lenders,  meaning we're totally focused on delivering value to our customers.


We keep our promises, provide upfront timelines and bring predictability.

A self-confessed marketing geek with a fetish for spreadsheets, Johannes is in his element when solving problems and building systems for solutions.
