They don’t have to balance community and customers. </p> <p>If you’re building an open source company, those are among your core strategic challenges. OSFS is a no-bullshit place where founders of open source companies can learn from and collaborate with each other to build more successful individual businesses and a stronger ecosystem of open source companies.</p> <p><a href="/about">About</a></p> </section> <section class="growth"> <h2>How will <a href="https://www.linkedin.com/company/open-source-founders-summit">#05F525</a> help your business grow?</h2> <h3>Get feedback, be inspired, meet your peers, and get unstuck.</h3> <p><strong>Benchmark your performance:</strong> See how your company’s stats measure up, which metrics to pay attention to, and how to make those metrics move in the right direction. </p> <p><strong>Gain new skills:</strong> Get concrete strategies and tactics to try out in your business.</p> <p><strong>Form lasting connections:</strong> Build relationships with industry leaders and peers.</p> <p><strong>Get unstuck:</strong> Workshop your specific challenges; get inspired by others’ approaches to similar challenges.</p> <p><a href="https://05f5.com/schedule">Browse the Schedule</a></p> </section> </div> <div class="container clearfix"> <section class="participants"> <h2>Who is participating?</h2> <h3>The event is for founders of open source companies, big or small.</h3> <ul class="avatars clearfix"> <div class="avatar"> <a href="https://05f5.com/participants/frank-karlitschek"> <img src="https://05f5.com/assets/img/participants/frank-karlitschek.png" alt="Frank Karlitschek ()"> </a> </div> <div class="avatar"> <a href="https://05f5.com/participants/amandine-le-pape"> <img src="https://05f5.com/assets/img/participants/amandine-le-pape.png" alt="Amandine Le Pape ()"> </a> </div> <div class="avatar"> <a href="https://05f5.com/participants/adam-jacob"> <img src="https://05f5.com/assets/img/participants/adam-jacob.png" alt="Adam Jacob ()"> </a> </div> <div class="avatar"> <a href="https://05f5.com/participants/john-o-nolan"> <img src="https://05f5.com/assets/img/participants/john-o-nolan.png" alt="John O'Nolan ()"> </a> </div> <div class="avatar"> <a href="https://05f5.com/participants/jonathan-ellis"> <img src="https://05f5.com/assets/img/participants/jonathan-ellis.png" alt="Jonathan Ellis ()"> </a> </div> <div class="avatar"> <a href="https://05f5.com/participants/peter-zaitsev"> <img src="https://05f5.com/assets/img/participants/peter-zaitsev.png" alt="Peter Zaitsev ()"> </a> </div> <div class="avatar"> <a href="https://05f5.com/participants/thomas-di-giacomo"> <img src="https://05f5.com/assets/img/participants/thomas-di-giacomo.png" alt="Thomas di Giacomo ()"> </a> </div> </ul> <p> Some of the speakers include: <a href="https://05f5.com/participants/frank-karlitschek">Frank Karlitschek</a> (NextCloud), <a href="https://05f5.com/participants/amandine-le-pape">Amandine le Pape </a> (Element), <a href="https://05f5.com/participants/adam-jacob">Adam Jacob</a> (System Initiative), <a href="https://05f5.com/participants/john-o-nolan">John O'Nolan</a> (Ghost), <a href="https://05f5.com/participants/johnatan-ellis">Johnatan Ellis</a> (Datastax), and workshop faciliatators such as <a href="https://05f5.com/participants/peter-zaitsev">Peter Zaitsev</a> (Percona), <a href="https://05f5.com/participants/kevin-muller">Kevin Muller</a> (Passbolt), <a href="https://05f5.com/participants/thomas-di-giacomo">Thomas Di Giacomo</a> (Suse)! </p><p> Expect conversations and workshops with leaders from open source organizations such as Suse, Kiwi TCMS, Matomo, Open Social, Eclipse Foundation, Mailvelope, Passbolt, Gatling, Zulip, XWiki, Packagist, Dolicloud, :Probabl, FerretDB, YottaDB & <a href="/participants">more</a>... </p> <a class="cta" href="https://05f5.com/request-invite">Get tickets</a> </section> <section class="where"> <h2>Where?</h2> <h3>La Rotonde Stalingrad, Paris</h3> <p>6,8 place de la bataille de Stalingrad, 75019 Paris, France.
