Contact me


Got an idea? Have a question? Looking for a mentor? I’d love to learn and share!

I prefer blog comments, Twitter, e-mail, text messages, then phone calls (+1 416 823 2669 – cellphone), in that order. If it’s urgent, call me on my cellphone or send me a text message. There may be a delay for text messages. You can leave voicemail for me at +1 647 547 9436. I check this once a day.

I currently don’t accept advertising, press releases, and other commercial material for my blog. Because this is a personal blog, I rarely accept guest posts (especially not generic ones). If you have something you think really fits my interests, send it to me, explain why it’s a great fit, and we might talk about it.

You can e-mail me at [email protected]. I tend to respond to e-mail weekly.

Interviews and presentations

I’d be happy to help you and your audience learn more about topics of mutual interest. Some of the less-common things I do are:

I’ve made a commitment to openness and scale. This means:

  • If we have a video or audio interview/presentation, I’ll post the recording on my YouTube channel and the resources on my blog. If you’re okay with it, I’d love to open up the interview or presentation to a live audience as well. I can set up and facilitate a Google Hangout on Air.
  • If we conduct the interview by e-mail, I’ll also post the results on my blog.
  • I’ll share any resources I create under the Creative Commons Attribution license. You retain the copyright to anything substantially created by you, and we can negotiate if things are mixed.
  • If you prefer to be unattributed, I can anonymize the names. If you are open to being linked to, I’ll include a link at my discretion.

If your audience is part of an exclusive membership site or you’re interviewing me for something commercial, that’s all right, as long as my part is freely available (at least on my side). You’re welcome to offer that part as a free preview on your side, which may be a good way to market the rest of your paid content. If you charge a fee for access to your content or have sponsors, please disclose that in your request. We can work out suitable arrangements.

I strongly prefer presenting on the Web over travelling to conferences because of the convenience and because more people can access the results. However, I will consider travelling to conferences that strongly appeal to me (ex: Emacs), especially if travel and/or accommodations are covered.

    Hello Sacha. First of all, I would like to say huge thank you for everything you have done so far! I recently learned about your blog and sketchnoting. Since then, I have been searching frantically apps, stylus, and other techniques to practice and develop my sketchnote taking and visual recording skills. I currently own Asus 10.1 tablet (1.5 years old). I recently tried out Artflow free version app with standard stylus (not fine tip) and noticed it did skipping (not drawing a smooth line) quite significantly. I wonder if it’s because my skills are still not equipped, because it’s free version, or because my stylus is not thin enough or my tablet itself is too slow.. I want to ask what your opinion is about that. I’m more towards to either my lack of skill but want to know if there is anything I can do to correct that.

    Thank you so much for your great work!

      It’s great that you’re playing around with that! Yeah, responsiveness is a big deal. I ended up giving up on my Asus Transformer tablet because it was just not as smooth as I wanted. The pro version is probably not going to be more optimized than the free one you have; it likely just has additional brushes or features. I’ve heard lots of people be happy about drawing on iPads, but that’s yet more hardware to try out! Maybe paper for now?

      I use a Lenovo X200 tablet PC because that gives me the smoothest experience (with the slight annoyance that Windows 8.1 means I can’t disable touch, so my palm occasionally messes up the drawing; I miss Windows 7). It’s a bigger machine than most people are looking for, though.

        Thank you very much for such a quick reply! I should have invested more money when I first looking for a tablet to buy, but iPad is such a wonderful device, still to me it is too expensive.. (That’s why I chose Asus 10.1 memopad at first place and it was on sale). For now, I should practice more on paper until I have sufficient money to indulge another gadget. Thank you so much your reply. I hope you keep in touch with you.

    Hi Sacha. I was going through your emacs config file to get started and it turns out the link to the “Emacs-Starter-Kit” is dead now. It can still be found on

    Here you go:

    The link titled “Making the most of my introversion” results in a 404. I’d love to read your writings on that topic.
