Hi @collinglass . I think you might want to revisit the premise of your question. Growth hacking should be used to accelerate growth after you have achieve product/market fit. It is a common mistake to try to force growth prematurely. Doing so is frustrating, expensive and unsustainable – killing many startups with otherwise strong potential. I recommend that you read this article I wrote years ago http://www.startup-marketing.com/milestones-to-startup-success/

One exception to this rule is if you have a network effect business. In other words, you require a critical mass of users to validate if you have product/market fit. Here's a presentation that I did years ago to explain what you need to do for this type of business http://www.startup-marketing.com/bringing-a-network-effect-business-to-market/ .

Tons of great resources, thank you all for answering my question!

Not articles but these are a couple of my go-to resources:

I recently came up with an article on product/market fit. I hope this might help you out: http://www.hammadakbar.com/saas/8-practical-steps-measure-product-market-fit-saas-startup/

This isn't an article, but The Product Lunch (webinar series) recently recorded: 'The Elusive "Product-Market Fit": How to get there, and set yourself up to scale' with Dan Olsen. You can watch the reply here :) https://www.crowdcast.io/e/product-market-fit/register

I agree with @Sean on this one. A tough (if not impossible) question to best answer without clarity or purpose behind the combination of those 2 loosely defined and often brutally abused keywords, @collinglass...

For "Growth Hacking" - the best articles would depend on your definition of that term... Andrew Chen, the keyword's inventor, is always a good place to start on this one. If marketing or product launch-related in your purpose, check out Ryan Holliday's "Growth Hacker Marketing" book - http://amzn.to/2ik4odr ...

...and his blog here: http://ryanholiday.net/category/blog/

If "growth hacking" for Product-Market Fit is more product dev in focus - check out Nir Eyal's Book - http://amzn.to/2j85A5e - and his blog... http://www.nirandfar.com/best-of-top-picks

Product Market Fit? Sheezz... tons of experts on that as well, here's an introductory guide (video + checklist) to niche market entry from Ryan Levesque (author of ASK - http://amzn.to/2j88uXt) which covers PMF and niche market entry quite well --> http://unfunnel.com/niche-market-entry-video-checklist
