Stock API Industry Landscape and Platform Strategies

As a financial data API platform, how should Alpha Vantage design its platform strategy that scales and provides sustainable competitive advantage?

Editor’s Note:

Since the publication of the original article, the industry landscape for stock APIs and financial data providers in general have evolved significantly. To better capture the latest trend, we have updated the structure of this review, as detailed below.

In Summer 2017, millions of tech-savvy individual investors around the world realized one ominous fact: The Yahoo Finance API has been deprecated after its parent company had been acquired by Verizon. For more than a decade, the Yahoo Finance API had been the only free data source for global stock and currency markets, while enterprise-level data providers such as Bloomberg and Thomson Reuters charged exorbitant fees for data access. Scrambling for an affordable, high-quality alternative, those “yahoo finance migrants” were pleasantly surprised to find on search engines (Figure 1) that another company – Alpha Vantage –had quietly filled in the institutional void. In this blogpost, we survey the strategy of Alpha Vantage against the industry backdrop of financial market data platforms.

Value Creation

Alpha Vantage is a cloud-based API service that provides a variety of financial market data feeds to any user around the globe who has an internet connection. Its existing portfolio of data feeds include stocks, ETFs, mutual funds, physical currencies, and digital currencies such as Bitcoin (Figure 2). Launched in March 2017, the Alpha Vantage now has around 60,000 registered users, fielding over 200 million daily API requests from a global user base. The API service creates values for two categories of users. For software developers, Alpha Vantage provides an industry-standard RESTful data feed to help the developers integrate any finance/investing-related experiences into their software applications (e.g., a wealth management iOS/Android app, an interactive stock visualization tablet app, etc.). For tech-savvy individual investors, Alpha Vantage provides historical and realtime financial market data for investors to build, test, and simulate their trading strategies. As of February 2018, Alpha Vantage has a roughly 50/50 split in terms of the two user categories described above. Alpha Vantage also has spreadsheet add-ons for Excel and Google Sheet customers.

Value Capture (and its difficulty)

From the outset, Alpha Vantage has been positioned as a developer-first, cloud-first platform that provides the “raw ingredients” for software developers to build compelling financial and trading software applications. Alpha Vantage’s free, high-quality APIs have been well received by the software developer community, as manifested by the backing of vibrant open-source communities on GitHub (Figure 3), StackOverflow, DevPost, and other prominent sites where developers congregate. Unlike other innovation platforms such as iOS or Android, however, Alpha Vantage does not own an “app store” and has limited visibility into the exact types of applications enabled by the API service. Such limitation has exposed Alpha Vantage to the risk of disintermediation, bringing significant friction to the value capturing process.

Open-Source Adoption of Alpha Vantage on GitHub

Figure 3. Alpha Vantage adopts an “open platform” strategy that encourages external software developers to create third-party applications, libraries, and SDKs on top of the Alpha Vantage data feeds. To date, over 70 open-source software applications have emerged on the popular software development website, GitHub. (Editor’s note, as of May 1, 2020, the number of Alpha Vantage-related repos on GitHub has ballooned to 400+). 

Alpha Vantage has experimented with two value capture mechanisms to date. The first mechanism is a SaaS-based freemium subscription model where premium features (e.g., unlimited API calls, exclusive data feeds, etc.) are accessible through a tiered-pricing structure. However, the low multi-homing tendency in the financial data API market, coupled with significant cross-side network effects among application builders and consumers, has bred a competitive dynamic characterized by price under-cutting and excessive marketing spending, both of which are unattractive and unsustainable to a bootstrapped and cash-constrained business. The second value capturing mechanism is the “data play” reminiscent of the Ant Financial case in Digital Innovation and Transformation. Fielding over 200 million API calls on a daily basis, Alpha Vantage has inadvertently become a barometer of financial market sentiments with a growing global user base covering major stock exchanges around the globe. How can Alpha Vantage leverage the streams of data coming into its platform and derive value and insights from its growing data assets? One thing is clear: the “data play” would be capital- and talent-intensive.


Looking forward… 

In February 2018, the founders of Alpha Vantage gathered in the Innovation Lab (iLab) of Harvard Business School to finalize their product roadmap and platform strategy going into the new year. How could Alpha Vantage effectively mitigate the disintermediation risks surrounding their stock API platform? How could they build a competitive “moat” around their core API offerings? What monetization strategy should they choose to scale up the business as the total number of registered API users was expected to reach 100,000 by the Harvard Commencement in May 2018?

  1. Hi Rexxar, what an awesome company you founded, this is really interesting! Congrats on all of the progress that your cofounder and you have made. Verizon acquiring Yahoo and creating the market need for your services is an amazing blessing and should really help you to catapult the growth of your business. In the paragraph about value capture you mention two models that the company has tried so far. In the first one, you refer to low multi-homing costs. I was a little confused by this because I had thought that part of your appeal was that there were no other, credible, free sources. Is that not the case?

    1. Thanks for the encouraging note! Umm… I tend to think that low multi-homing *tendency* (the term used in the blogpost) is equivalent to high multi-homing costs? We are essentially converging on the same concept 🙂

      1. Ahh, thank you for the clarification, that was my confusion! Thanks for explaining!

        1. The pleasure is mine 🙂

  2. Hi Rexxar – Thank you for stepping in and filling a huge void in the finance api world. I am a huge fan of your service and building into an app based on it. The value capture issue (i.e. revenue) is quite important as I would love to see the service continue, and a visible value capture/revenue model would give confidence. I’d certainly be willing to pay for more certainty in the ongoing viability for AV. Do you guys have a timeline for figuring out your business model? Cheers, Steve
