What we give

One of our values is that we involve people we love. To us, this means spending time with our families, and investing in our communities. We participate and contribute where we can, to our communities, to events, and with donations.



As long-time members of the global and Australian Ruby, JavaScript, and web standards communities, we have a long history of participation in those communities. Elle has run multiple Ruby Conferences and Rails Camps, and served as a member of Ruby Australia. Lachlan has also served on the Ruby Australia committee, as Vice-President and as a general member. Together, they ran USA Rails Camp East in 2016.

In 2018, they served as advisors to the organisers of the inaugural Levels Conf. Australia’s first conference dedicated to supporting software developers new to the industry.

In 2020, Elle served as Treasurer of Maribyrnong Kinder .


Elle and Lachlan ran pizza-making workshops at Ruby Conf Australia 2019 , Rails Camp South 2019. , and Elixir Camp 2019 . They also cooked homemade pizza for the children and staff at a local daycare centre in Footscray, Melbourne, twice. And host a regular open house pizza event that anyone is welcome to join: Pizza Friday. During the COVID-19 pandemic, Pizza Friday has become a regular virtual event.


Each week, Blackmill hosts a book club to explore with others concepts that intersect with our work. It’s a friendly conversation over lunch about software, leadership, and engineering practices. Everyone is welcome.

We state in our values that we share our profits with charities we believe in. We commit 1% of last year's revenue to be distributed on a quarterly basis.

Financial Year 2021

Most asylum seekers in Australia are not eligible for any form of government support, including JobSeeker, or any of the COVID-19 relief schemes.

The Australian Literacy and Numeracy Foundation (ALNF) is dedicated to raising language, literacy and numeracy standards in Australia, and raises funds to develop, implement and sustain innovative projects for individuals, families and communities.

Each member of the team received $100 to donate via Good Thnx . The remainder of our 1% revenue commitment was distributed evenly amongst four organisations: Asylum Seeker Resource Centre , Kids Under Cover , Stars Foundation and The Australian Literacy and Numeracy Foundation (ALNF) .

Financial Year 2020

Stars provides a holistic program that supports Indigenous girls and young women to attend and remain engaged at school, complete Year 12, and move into full-time work or further study.

Greening Australia works on restoring Australia’s fragile and diverse ecosystems and habitat. By doing so, they restore local economies with them, and help to create healthy, productive landscapes where people and nature can thrive.

WIRES' mission is to actively rehabilitate and preserve Australian wildlife and inspire others to do the same.

Each member of the team received $100 to donate via Good Thnx . The remainder of our 1% revenue commitment was distributed evenly amongst four organisations: Stars Foundation , Kids Under Cover , Greening Australia and WIRES .

Financial Year 2019

One woman in Australia is murdered by her current or former partner every week, on average. One in every five women over the age of 15 in Australia has experienced sexual violence. These are horrifying statistics. The numbers are difficult to even contemplate, let alone the individual realities behind them.

It is not enough, but in our second year of operation, we contributed 5% of our profits to the White Ribbon Campaign.

Financial Year 2018

Kids Under Cover builds relocatable 1-2 bedroom studios, with a bathroom, in the backyard of a family or carer’s home to provide vulnerable young people at risk of homelessness with a secure and stable environment. They also offer scholarships for education or job training, offsetting basic education costs to empower young people to achieve their goals. These scholarships are not just for the people in their accommodation, but also their siblings in the main home — helping to break the cycle of poverty and disadvantage.

Our first year of operation, we contributed 1% of our profits to Kids Under Cover. A 30 year old not-for-profit that started here in Melbourne, we have a lot of admiration for both their mission and their approach to solving it.
