211 Startup Tools, Posts & Resources for B2B Entrepreneurs in 2021

There are thousands of startup tools and resources out there, with more coming online every week. As a B2B founder trying to save startup runway and minimize time to product-market fit, it’s sometimes difficult to differentiate what will help from the things that will distract you from your goals.

To help founders get set up with the best startup tools and resources, I put together a list of tried and tested tools, resources, and key posts, categorized by focus areas. You can refer back to this list as your business challenges change and evolve over time. Here it is:

12+ Conferences for B2B Entrepreneurs Looking to Grow Faster in 2018

🆕  A new version of this list is available for 2019. Read: 13 B2B Conferences to Accelerate Your Startup’s Growth in 2019.

It’s often difficult for B2B entrepreneurs to see the forest for the trees. They get consumed by a business problem and can’t seem to find a solution.

Conferences provide a great opportunity to take a step back. Interacting with other B2B entrepreneurs or seasoned executives can help generate fresh B2B business ideas, opportunities and a renewed mindset to accelerate growth.

Sometimes, seeing what’s out there is all you need to find a solution.

To help founders find the best events for their needs, I put together a list of the best conferences in B2B:

General-Topic Conferences for B2B entrepreneurs

  • SaaStr – February 6-8, 2018 / San Francisco
    Founded by Jason Lemkin 4 years ago, SaaStr Annual brings together over 10,000 SaaS Founders, VCs and Executives. It’s a good place to network, strike deals, and discuss SaaS business, fundraising, enterprise sales, customer success and metrics.
  • Dreamforce – September 25-28, 2018 / San Francisco
    Dreamforce is Salesforce’s annual event. It was one of the first B2B conferences and it’s, by far, the largest event with nearly 200,000 participants, 3,000 sessions and a lot of corporate money. It’s a great place to make deals.
  • SaaStock – September 15–17, 2018 / Dublin, Ireland
    The European SaaStr. It covers a lot of the similar topics (Sales, Customer Success, Growth and Funding) with a lot of the same speakers, but it’s an excellent opportunity to get acquainted with the best European founders and investors.
  • Revenue Summit – March 1, 2018 / San Francisco
    Revenue Summit was started by SalesHacker. It focuses on sales, marketing and the intersection between the two disciplines. With a strong emphasis on processes, account management and sales tech, it’s a good place to go a bit deeper into B2B sales.
  • Marketing Nation Summit – April 29-May 2, 2018 / San Francisco
    Marketo’s conference covers all things marketing with a strong focus on the B2B space. It’s an interesting alternative to Salesforce’s conference especially if your startup is selling to marketing executives.
  • Business of Software – October 1-3, 2018 / Boston
    The Business of Software conference focuses on creating quality networking opportunities and teaching participants how to build better products and be better B2C or B2B entrepreneurs. This year, the BoS conference returns for a 12th time.
  • Inbound – September 4-7, 2018 / Boston
    Hubspot’s conference attracts thousands of sales / marketing professionals. It’s a great place to network with almost 20k attendees and learn about content marketing, marketing automation and account-based selling. The conference often features some of the foremost leaders in B2B.
  • B2B Rocks – June 1, 2018 / Paris, France
    B2B Rocks organizes events in Paris, France and Sydney, Australia. It attracts different crowds with strong emphasis on local expertise. At the event in Paris, you’ll learn tactics to grow your B2B SaaS product.
  • Hyper-Growth – September 4 / Boston & September 24, 2018 / San Francisco
    Hyper-Growth is Drift’s conference. The first event is held in Boston the first day of the Inbound conference and the second is held later in San Francisco. Hyper-Growth has a stronger focus on sales and customer-centricity than the Inbound conference.

B2B Conferences Around Specific Challenges

Many B2B companies have created conferences around their customers’ business challenges. If you share these challenges, or wish to dive deeper into topics like customer success or inside sales, great conferences are available for you or the people on your team:

Customer Success

B2B Content Marketing

Industry Events for B2B entrepreneurs

Events and conferences are shortcuts to target markets. To speed up product-market validation or increase your growth rate, you can attend your customers’ events or visit your customers’ watering hole.

It might be the HR Technology Expo if you’re targeting HR professionals or the DIA 2018 Global Annual Meeting if you market to companies in pharma. Networking with your target market is a great way to create new opportunities.

Conferences are all about networking opportunities. By asking yourself, what kind of professionals the event targets and seeing how that fits within your strategy, you’ll make sure to always have a positive return on investment when you attend a conference.

65 VC Firms and SaaS Angel Investors to Fund Your B2B Startup

If you want money, ask for advice, and if you want advice, ask for money. – Unknown

When raising money for your B2B startup, it’s important to realize that, beyond terms, B2B investors won’t all bring the same value to your business.

Some investors will be very involved while others will not. Some will open gates for you, help recruit top employees, show you the ropes, and remain solid partners all throughout the life of your startup. And again, some will not.

In B2B, the best investors understand how B2B and B2C startups differ, they have connections in your industry, and know what it takes to win in B2B. Those investors can significantly improve your odds of success.

To help you find the right partners, I’ve put together a list of SaaS angel investors and partners at leading VC firms actively investing in B2B SaaS companies. This is a list I wish I had when we raising money for Psykler.
