Substack Financial Journey

  • Substack statistics state that Substack just crossed a fantastic milestone of 1 million paid subscribers, but still, the profitable level has not been reached.
  • The platform does not reveal its revenue or financial information, and secondary sources help in painting its performance picture.
  • Substack makes a 10% commission on the subscription fees collected by the creators.
  • No official figures on revenue are available, but the company told its investors that it earned US$9 million in revenue in 2021.
  • Since its establishment in 2017, Substack has conducted four rounds of investment involving 15 investors for a total of US$82.4 million.
  • Prominent venture capital Andreessen Horowitz (a16z) marked Series A and Series B investment rounds, injecting a total of US$80.3 million into it.
  • Also, it was part of an incubator program by Y Combinator in which US$120,000 was earmarked for the pre-seed fund.
  • Substack statistics show that in April 2023, Elon Musk made an unexpected offer to buy Substack after he had just taken over Twitter (now X). According to sources familiar with the conversation.
  • Musk reached out to Substack CEO Chris Best with an offer to accelerate paid subscriptions on X-a platform long viewed as a "global town square" for political news and debate-would include him as CEO of the combined company.

Substack Valuation

Substack Valuation(Source: sacra.com)

  • According to Substack statistics, Substack initiated an equity crowdfunding campaign through WeFunder to raise US$5 million at a US$585 million pre-money valuation in March 2023.
  • This valuation represented a 30x multiple on US$20 million of trailing twelve-month (TTM) revenue.
  • It was consistent with a flat valuation from their 2021 Series B round, where Andreessen Horowitz led a US$65 million investment at a 102x revenue multiple, compared with the US$6.41 billion value of the New York Times at a 2.8x multiple on US$2.31 billion revenue.
  • Meanwhile, The Athletic was acquired at US$550 million on US$65 million in revenue in 2021. So, it reflected a multiple of 8.5.
  • For now, it puts Substack between US$29 million at a conservative 1x multiple and US$713 million at an ambitious 25x multiple.
  • This is right on the high end of the recent US$585 million pre-money valuations but is still way below the 102x multiple from the 2021 Series B round.

Substack’s Business Model Faces Several Key Risks

  • For new subscriptions to paid newsletters, on average, churn levels are around 50% a year. That means their income would fluctuate quite a bit, making earning that much tougher for writers.
  • For example, for an annual income of US$50,000 at a US$8 monthly subscription price, a writer would need 900 paid subscribers. Beyond that, a writer must acquire 31 new subscribers every month just to hold his income.
  • There is much pressure to keep producing such high-quality writing at this rate, which leads to burnout. On a grander scale, the kind of mass burnout that can happen among writers can be such that.
  • Substack might end up losing many of these writers from the user base and lose its appeal, too. Substack’s promise also lies in the reputation that generates the fine writing that attracts more writers into its fold.
  • Yet, if the strongest writers – the ones that were mostly raking in the dough and contributing the most in either commissions or revenue to Substack – left this platform for DIY options or other places, it would not be good for Substack acquisition or revenue models. That can really set off a downward spiral for the platform.

  • For Australia, it contributes to traffic by 2.26%, and it has the highest growth rate of 8.80%. On the contrary, India’s share is only 1.91%, showing a minor decline of 1.50%.

Substack Marketing Channels

  • Substack focuses on multiple marketing channels for user acquisition and retention.
  • According to Substack statistics, the most relevant traffic source is direct, accounting for an incredible 60.05% of all visits, as evidenced by a strong user base that accesses the platform directly.
  • The organic search takes up 17.25% and indicates quite a promising visibility of Substack on search engine results.
  • Similarly, social media is quite important, driving 14.79% of traffic. Referrals, by definition, indicate the partnerships or just simply links from another website: they account for 7.72%.
  • Email as a marketing source is more than central to Substack’s product, but only a modest 0.12% traffic source can be linked.
  • Such search and display ads would only contribute to traffic totals of 0.03% and 0.04%, respectively, hence considering that paid advertising does not heavily rely on growth.
