Even the most experienced entrepreneurs know that you never reach a stage in your career, or in life for that matter, where you stop learning. The internet gives us access to some of the best tools available to further our learning, often at absolutely no cost.

Some of the best resources for learning about life as a startup founder are the blogs written by venture capitalists. These investors were often entrepreneurs beforehand, and provide key insights to what it takes to successfully run a business.

Here are ten blogs written by VCs that can provide some serious insight for entrepreneurs.

1. FeldThoughts

FeldThoughts is the personal website of Brad Feld, a managing director at Foundry Group in Colorado. Posts on FeldThoughts cover a variety of topics from startup best practices to Feld’s personal life. His archive of posts is well-categorized and tagged, making it easy to find information on a problem you may be having.

2. Tomasz Tunguz

Redpoint VC Tomasz Tunguz maintains a great blog on fundraising and the lifecycle of a startup. Posts are generally data-heavy, including graphs and charts showing trends in a particular market or sector. His insight on startup benchmarks will be particularly helpful for first-time founders.

3. Bothsides of the Table

Mark Suster’s blog Bothsides of the Table delivers on its name in that Suster shares insight from the perspective of both the founder and the investor. Suster also runs an interview show called BothSidesTV that is worth checking out.

4. Ben’s Blog

Ben’s Blog is the blog of Ben Horowitz, the latter half of VC firm Andreessen Horowitz. The blog offers wisdom to entrepreneurs and more traditional professionals as well, plus he starts every post with rap lyrics. Posts are short enough to be easily digestible, but provide serious value.

6. CDixon Blog

Chris Dixon is a partner at Andreessen Horowitz, but before that he founded a few successful startups and operated as personal investor in some of the top tech startups such as Warby Parker, Stripe, and Pinterest. His blog focuses on individual companies and markets, and he has great thoughts on both. He doesn’t post as often as some others on this list, but the post quality makes up for the lack of frequency.

7. For Entrepreneurs

For Entrepreneurs is a blog by David Skok, of Matrix Partners. Skok often posts proprietary industry survey results and provides great details on SaaS startups, especially. Enterprise and general B2B startups should get a lot out of this blog.

9. Open Source Venture Capital

Subtitled “How I learned to stop worrying and love entrepreneurs,” Open Source Venture Capital is the blog of Fred Destin, of Accel in London. While his posts are infrequent, they are often long and very detailed. The posts are great to read on your commute or on a short flight.
