📈 A Fundraising Guide for Open-Source Founders
I've heard you loud and clear :)
Today's digest is all about the topic you've been asking for the most!
Since "Raising a Series A for a DevTools Startup" and "Making Money from Open Source" were the most popular topics in my previous digests, I decided to gather the best resources on this topic.
Let’s delve into a two-part series about open-source fundraising:
So How Many Stars Is Enough? A Data-Driven Guide to Fundraising as an Open-Source Founder
Can My Open Source Company Raise Series A?
Let's take a look at the first overview.
1. Overview - So How Many Stars Is Enough? A Data-Driven Guide to Fundraising as an Open-Source Founder?

Open source companies at the earliest stages are viewed like social networks. Building community momentum is the most critical factor for the success of an open source project, and revenue is not necessary if you have the other criteria accounted for.
Many investors will say revenue is one of the most important factors to consider when evaluating an open source company, but in reality, at least 49 of the 69 seed companies in the dataset had no revenue at the time of their financings.
GitHub stars are a controversial open source metric, but VCs do pay some attention to it. The median value of stars for the 54 seed companies in the dataset that had released their open source project at the time of their financing was 2,850. The median star value for the 48 Series A companies was 4,980.
Other factors to evaluate open source investment opportunities include contributors, Slack/Discord, downloads/user growth, quality of design partners/customers and use cases, market and product, and team and storytelling.
Data is imperfect and incomplete, and some stats are from fundraising pitches, while others are from when their fundraising announcements occurred. Thus, the numbers presented are upper bounds of traction as the financings occurred prior to the announcements.
Overall, community momentum is more important than revenue, and stars can pique the interest of the investor but won't land the role. Other factors should be considered when evaluating open source investment opportunities.

Let’s continue the open-source fundraising series with the part 2/
2. Overview - Can My Open Source Company Raise Series A?

Historically, open-source companies could raise Series A and even Series B without a commercial product or strategy, but this has changed.
67% of investors say their view on ARR at Series A has changed over the past few years. At least $100K ARR is required, and while 50% of investors say they're looking for $100K - $500K ARR, more investors may move into the $500K+ ARR range if the macro environment doesn't improve.
The top 5 open source metrics investors care about are:
Users Running the Project in Production (59% of investors want to see 10-50 production users by Series A, while 29% want to see 50-100).
Users from Mid-Market & Enterprise Companies (39% of investors want to see usage by 5-10 mid-market and enterprise users by Series A, while 33% want to see 10-20).
Users in Slack or Discord (67% of investors expect 500-1K members in a project's Slack or Discord by Series A).
Number of GitHub Issues (71% of investors look for 100-300 GitHub issues by Series A).
Number of GitHub Stars (60% of investors expect 3K stars or more at this stage).
Other metrics investors look for include usage and retention of users, unique monthly contributors, diversity of companies using the project, conversion ratios, annual contract value, and NPS of production users.
Remember that metrics alone are only part of the story, and your project's market and the team's expertise are also crucial factors that investors consider when deciding whether to invest in your company.
