Elle is a back-end engineer with more than 15 years of consulting experience, leading projects and teams for many technology organisations. Elle recently completed a post-grad certificate in Psychology for Business and Management at Curtin University, learning new ways to help people improve how they work. She was part of the Victorian Government's Industry Advisory Panel to help assess digital skills training courses for the new Digital Skills and Jobs Program. Elle ran two 6-month apprenticeship engineering academies for Qantas Hotels and Disco Labs. At Blackmill, she advises executives and engineers in effective management practices so that they become engaging, thoughtful and inclusive leaders.
In 2014, Elle organised Rails Girls events in Sydney, RubyConfAU 2014, and was a member of the Ruby Australia committee. In 2015, she co-organised Gotham Ruby Conference (GORUCO) in New York City, and started a monthly work jelly for women in tech. In 2016, she co-organised Rails Camp USA East Coast in the Catskills, NY with Lachlan, and once again co-organised GORUCO X. In 2018, she was an advisor to the last GORUCO conference.
Lachlan has over 20 years of industry experience and knowledge as a developer, leader, and speaker.
Before Blackmill, Lachlan worked with some of the world's renowned companies including GitHub, Neo, Microsoft, Bigpond, Ninefold, Atlassian, and News Digital Media.
He loves attention to detail, efficiency, and quality that only a care for your craft can produce. His work ethic, empathy, and ability to adapt to various roles has enabled him to bring big picture thinking to many of our clients' projects to deliver sustainable quality outcomes.
Lachlan has been a speaker at many conferences since 2007. His latest talks include Re-imagining the Hiring Process at the Bifrost Tech Leadership Conference in Toronto in 2018 and Developer Culture that Doesn’t Suck at ManhattanJS in 2015.
He went to Sydney’s first Ruby on Rails meet up in 2006 and has been an active member of the Australian Ruby community ever since. He is also a habitual starter of community events, such as the long defunct industry demo night, Webjam; Australia's longest running startup meetup (probably), Silicon Beach Australia; and the only Sydney web industry social event held in a tequila bar, Friday at 4 (or most likely at 5).
He also founded and ran a coworking space called The Workbench in Sydney and helped organise the Sydney JS meetups. While living in New York City, he co-organised Rails Camp USA East Coast 2016 with Elle.
If he offers you a cocktail, or a meal, expect the best he has learned to make, with a healthy dose of experimentation to keep on learning.

Sebastian is an experienced engineering leader with over 15 years in the industry. As an alumni of Australian start-up and scale-up successes Culture Amp and Envato, as well as other companies, he has led teams small and large. Most recently as VP of Engineering at Culture Amp, he was responsible for a 150-person engineering organisation and was involved in cross-cutting organisational initiatives and acquisitions.
While Sebastian has broad knowledge of and interest in product and technical strategy, software architecture, and business processes, he always comes back to people leadership as his foundation. He believes that culture, feedback, and communication are the root causes—and solutions!—to most organisational issues. He loves working with people, and applies his curiosity and experience in helping others help themselves.
Sebastian was a founding committee member of Ruby Australia, where he has tenures as President and Treasurer. He organised RubyConfAU 2015, and Railscamp 10 in Adelaide, SA and 21 in Darwin, NT. He was a director of the Founder Institute's Melbourne chapter, and continues to advise start-ups on a broad range of issues.
On the speaking circuit, Sebastian has travelled internationally and all over Australia to give talks on organisational culture, software architecture, as well as engineering practices and processes. In particular, he's known for giving long (but somewhat entertaining) presentations about Event Sourcing, including this often-linked-to talk in Singapore.
Outside of work, Sebastian enjoys ice hockey, video games, collecting and cataloguing wine, and doting on his two cats. Ask him about his cats. He has a lot of pictures of his cats.
A Swede by birth and upbringing, Sebastian now lives in Melbourne, Australia. It was about the last place he ever thought he'd visit, yet alone live, but he found himself moving here in 2009. He has no plans to leave—at least not until he actually sees a snake.
Choosing the right name for a company is always hard. And then people ask for the story. Here is ours:
In Sydney, at the western end of what is now known as the Anzac Bridge sits what looks like a huge abandoned factory. Due to the flat terrain of the waterfront and parklands, and the sweep of the bridge, its silhouette dominates the horizon as you approach the area. A literal black mill.
Lachlan has always been fascinated by it and began to dream about how he might be able to re-purpose the building and grounds as a modern technology and community space.
The building is actually the White Bay Power Station which ceased operation in 1983. The NSW government has also had ideas about a technology precinct on the site, but is having difficulties making progress.
