Testimonials
What clients say
I have long donated 10 % of my net income to charity. The donation advising made me think about giving from a new perspective: it makes sense to give where the money can achieve the most. That is not always a familiar Finnish organization, because a euro can achieve much more elsewhere than in Finland.
In Karla's donation advising we went through my plans and thought together about how I could help as much as possible with my money. Thanks to Karla's broad knowledge, I got new perspectives on what kind of impact my donations could have. I especially liked how broadly the advising covered the different areas of giving.
I made a large anonymous one-time donation and Karla helped me decide how to allocate it. It was valuable to me that she took care of the decision-making process. The most important things were covered and the decision was made on time, even though my other commitments almost got in the way.
I know Karla has been familiar with the questions of effective giving for years, so it was easy to trust her advice and answers. Getting her view also reduced my worry about whether I was making the right decision. I also found it valuable that she gathered information from the organizations themselves and from other charity evaluators.
Why effective giving
Giving effectively makes your money go further
You surely want your donation to have the greatest possible impact on the cause you care about.
There is a plethora of different charities to give to. Fortunately it's possible to evaluate their impact. By choosing the charities with care, you can multiply the benefit of your donation.
In donation advising, I rely on research produced by evaluators including:

Karla Still
Former Director, Effective Altruism Finland · has personally donated over €10,000
When I discovered research on effective giving, it changed how I think about donations as a tool for social change.
Since 2020, I've spent hundreds of hours reading research on the most effective giving opportunities and thinking about where my own money would do the most good. So far I've personally donated over €10,000 — I wouldn't have, if I didn't believe the money was going to the best possible use.
I want to pass on what I've learned.
I served as Executive Director of Effective Altruism Finland for three years, and I'm currently studying sustainable entrepreneurship at Aalto University.
I don't receive compensation from any organization I recommend. When needed, I consult experts who research the most effective giving opportunities for different causes.

FAQ
Questions and answers
What topics do you know best?
Global poverty and health, animal welfare, and climate change. I try to be transparent about what I do and don't know, and I'll tell you honestly if an area isn't my strength.
How do I know your advice is unbiased?
I don't receive compensation from any organization I recommend. I rely on publicly available research, which you're welcome to check yourself. My knowledge is based on the work of research and evaluation organizations including GiveWell, Happier Lives Institute, Giving Green, Founders Pledge, Rethink Priorities, Coefficient Giving, Giving What We Can, Power for Democracies, and Animal Charity Evaluators.
I'm not sure I donate enough for this to be worth your time.
All amounts are welcome, whether you donate €200 or €20,000. The key question is usually not how much you give, but where. In global health, the best charities are up to 100 times more cost-effective than the average — so choosing a good cause increases your impact far more than giving a larger amount.
How much does the advising cost?
Advising is free by default. If you find the conversation valuable and want to support the growth of Lahjoita tehokkaasti, you can make an optional payment after the call. About half of clients pay. As a rough guide, I suggest €50–100 per conversation for monthly donors. For major donors, I suggest about two percent of the donation if the advising included separate research.
What if the conversation isn't useful to me?
Advising is free, so you have nothing to lose: payment is optional, and you only decide after the call. €0 is fine too.
How is my privacy protected?
All our conversations are confidential. If I ever share information about the service (e.g. in an annual report), it's always anonymized, and only if there are enough clients that individuals can't be identified. See the privacy policy for more.
Is this official financial advice?
No. This is a conversation about giving, not investment, tax, or legal advice. Decisions about your money are always yours to make. That said, I've thought a lot about balancing giving and saving myself, so we can discuss that too if it's relevant to you.
