A product with 20% detractors and 40% promoters would have an NPS of 20. That's an average score. Products with an NPS above 50 are considered great, and anything above 80 is world-class. The scale runs from -100 (all detractors) to 100 (all promoters).</p><p>Teams that craft high-NPS products focus on delivering magical and exciting experiences across every touchpoint. Companies that do this consistently don&#8217;t just have customers; they have advocates who drive organic growth across their entire brand portfolio. Some of these companies include Tesla (90s), Costco and Amazon (70s), and Apple (60s).</p><p>High NPS reflects customer trust and love. When products add exceptional value to people&#8217;s lives, customers become walking advertisements, compelled to spread the word. This often foreshadows strong future growth: nothing beats a friend&#8217;s recommendation.</p><p>Since companies exist to serve customers, and NPS directly measures customer satisfaction, NPS is the most important metric.</p>]]></content:encoded></item><item><title><![CDATA[Consistently Delightful]]></title><description><![CDATA[Great products are consistently delightful]]></description><link>https://blog.arieltamayev.com/p/consistently-delightful</link><guid isPermaLink="false">https://blog.arieltamayev.com/p/consistently-delightful</guid><dc:creator><![CDATA[Ariel Tamayev]]></dc:creator><pubDate>Fri, 20 Jun 2025 01:39:48 GMT</pubDate><content:encoded><![CDATA[<p>Delightful products are intuitive to use and easy to explain to friends. They feel whimsical, playful, and powerful.</p><p>Consistent products deliver the same experience each time they&#8217;re used. Most products are either satisfactory, mediocre, or good. Any given product rarely falls into just one of these buckets; sometimes it&#8217;s satisfactory, other times mediocre. Very few products feel consistently delightful.</p><p>Consistently delightful products evoke a deep sense of love from their users. They become evangelists, much like missionaries spread religion. As a result, the best products spread like wildfire, via the most powerful form of advertising: word of mouth. Think about the products you enjoy most - odds are you heard about them from a friend.</p><p>Crafting great products starts with identifying a user&#8217;s pain point or friction, often something they may have already gotten used to, or are unconscious of. Solving a user&#8217;s problem and exceeding their expectations in a first impression is a sign of a delightful product. Consistently impressing that same user means the product is truly special: it&#8217;s consistently delightful. You know you&#8217;ve built a great product when users can&#8217;t get enough of it: a product&#8217;s greatness is highly correlated with how upset users would be if they couldn&#8217;t use it anymore.</p>]]></content:encoded></item><item><title><![CDATA[We're building Pip]]></title><description><![CDATA[I&#8217;m building an educational robot named Pip with @Levi-Sheridan.]]></description><link>https://blog.arieltamayev.com/p/were-building-pip</link><guid isPermaLink="false">https://blog.arieltamayev.com/p/were-building-pip</guid><dc:creator><![CDATA[Ariel Tamayev]]></dc:creator><pubDate>Sun, 12 Jan 2025 04:34:20 GMT</pubDate><enclosure url="https://substack-post-media.s3.amazonaws.com/public/images/6a6f677a-98e0-497e-8d00-65eaffa8cf1a_1678x1186.png" length="0" type="image/jpeg"/><content:encoded><![CDATA[<p>I&#8217;m building an educational robot named Pip with <a href="https://www.linkedin.com/in/levi-sheridan">@Levi-Sheridan</a>.</p><p>The idea for Pip emerged from our personal frustrations: while Duolingo revolutionized language learning and Khan Academy transformed math education, we never had an equivalent platform for hands-on robotics exploration.</p><p>There are two key barriers in robotics education:</p><ol><li><p>Onboarding friction: Even basic projects, like getting an Arduino to blink an LED, can require hours of setup and troubleshooting for newcomers.</p></li><li><p>Static curriculum: Current robotics programs use rigid, age-bracketed learning tracks (e.g. 7-10 years, 11-14 years). Engaged learners quickly outgrow the limited available content.</p></li></ol><p>These issues existed when we were growing up, and they persist today.</p><p>Pip is designed to break down these barriers:</p><ol><li><p>With no assembly needed, Pip is ready to go straight out of the box: connect to Wi-Fi in under a minute and start learning.</p></li><li><p>Integrated with Pip, our web-based curriculum grows with learners: a Duolingo for robotics.</p></li></ol><p>Users first enter the Lab: a self-guided workspace featuring readings, videos, and coding exercises. As they progress, Pip runs their scripts in real-time for an interactive learning experience. Those who want to explore beyond the Lab&#8217;s structured lessons can use the Sandbox, where they&#8217;re granted complete creative control to code up whatever they imagine.</p><p>Pip contains many powerful industry-standard components (time-of-flight distance sensors, a 9-axis IMU [accelerometer, gyroscope, compass], and color and infrared sensors). We&#8217;re doing the heavy lifting of writing the firmware to interface with these sensors, making it easy for our learners to utilize everything via simple drag-and-drop coding blocks.</p><p>We&#8217;re designing Pip to be the tool we wished we had growing up - a platform that welcomes anyone with the curiosity and desire to learn and build.</p><p>We'd love to hear about your experiences with robotics kits/platforms, positive or negative.</p><p>Pip isn't available yet, but you can sign up for updates at the bottom of <a href="https://www.bluedotrobots.com/">our website</a>.</p><p>Thank you</p><p></p>]]></content:encoded></item><item><title><![CDATA[Why I'm starting a Substack]]></title><description><![CDATA[Hello Substack]]></description><link>https://blog.arieltamayev.com/p/why-im-starting-a-substack</link><guid isPermaLink="false">https://blog.arieltamayev.com/p/why-im-starting-a-substack</guid><dc:creator><![CDATA[Ariel Tamayev]]></dc:creator><pubDate>Sat, 04 Jan 2025 20:47:44 GMT</pubDate><enclosure url="https://substack-post-media.s3.amazonaws.com/public/images/e13a9e03-4e1b-4c5a-bca7-39089726e097_1788x1167.png" length="0" type="image/jpeg"/><content:encoded><![CDATA[<p>About a month ago, I posted: &#8220;<a href="https://x.com/actamayev02/status/1863292368465584473">I&#8217;m challenging myself to post daily on X. My goal is to become a more clear, concise, and precise writer, and to think out-loud on the biggest stage: the internet.&#8221;</a></p><p>That challenge has been going well. I&#8217;ve found the character limit to be a great forcing function for concise writing.</p><p>To further develop my writing skills, I&#8217;m going to start publishing long-form content to supplement my X posts. Like posting to X, it&#8217;ll be a good way to time-stamp my  thoughts, so I can see what I thought when and why I thought those things.</p><p>I also want to improve at distilling my thoughts and thinking more deeply and clearly.</p><p>Paul Graham recently published &#8220;<a href="https://paulgraham.com/writes.html">Writes an Write-nots</a>&#8221; where he predicted that &#8220;in a couple decades there won&#8217;t be many people who can write.&#8221; He explains: &#8220;The reason so many people have trouble writing is that it's fundamentally difficult. To write well you have to think clearly, and thinking clearly is hard.&#8221; With AI, &#8220;all pressure to write has dissipated.&#8221; Which will lead to: &#8220;a world divided into writes and write-nots&#8230; a world divided into writes and write-nots is more dangerous than it sounds. It will be a world of thinks and think-nots.&#8221;</p><p>But PG says today&#8217;s &#8220;situation is not unprecedented,&#8221; comparing it to &#8220;preindustrial times,&#8221; when &#8220;most people's jobs made them strong.&#8221; If you want to be strong today, &#8220;you work out&#8230; but only those who choose to.&#8221;</p><p>So this is one way I&#8217;m working out my brain. I&#8217;ve found myself using AI anytime I don&#8217;t want to think deeply about a topic, and I fear I&#8217;ll slowly become a &#8216;think-not.&#8217; I won&#8217;t use AI to write any essays on this blog, with the intent of re-learning how to translate my thoughts and reasoning onto paper without an intermediary.</p><p>Critical feedback appreciated.</p>]]></content:encoded></item></channel></rss>
