The Top 13F Filing Databases: Whalewisdom vs. Opportunity Hunter vs. SEC-API

If you sell in the RIA channel, you already know that there are no shortage of firms to call on within the United States. However, you probably also know how difficult it is to determine which are the right fit for your firm and your strategy. 

You probably feel like you’re shooting in the dark when you’re doing outreach. We know, we’ve been there too. 

At Dakota, we’ve been fundraising for our partners since 2006, and have raised over $40 billion in that time. We’re no strangers to the RIA channel and the challenges that lie within it. What’s more, we know that knowing who to call on can make or break your outreach strategy. 

However, in that time, we’ve also come to learn that when it comes to RIAs, knowing where they’re investing before you call on them can save your sales team a lot of time. Which is why, in this article, we’re going to outline three of the primary resources for information on 13F filings, which allow your team to know where RIAs are investing. 

We’re going to include our own new, 13F Filing platform at the end of this list as well, but don’t worry, we’re not here to convince you that our product is the only solution for you. Instead, our goal is to give you an overview of all four platforms, so that you can evaluate for yourself which is the best fit for your team

These platforms include:

  • Whalewisdom
  • Broadridge Opportunity Hunter
  • Dakota Marketplace 13F filings

By the end of the article, you’ll have a better idea which platform is right for your firm, so that you can start making more meaningful, targeted outreach to RIAs.



Whalewisdom was founded on the belief that there is value in learning from the “whales” of the stock market. They believe that everyone has something to learn from their peers, and the big firms and players within the industry. 

To that end, Whalewisdom has several options for users to choose from, including a product dedicated to 13F filings. In addition to this, though, they have the Whalescore, which allows users to quickly identify funds with the best chance of outperforming the market in the future, and the Whaleindex, which takes the best funds and creates a portfolio of their most commonly held stocks.

However, for the purposes of this article, we’re going to focus on the 13F Backtester, which allows users to see how cloning a fund or group of fund’s top holdings would have performed in the past, as well as the Excel 13F Holdings Extension

How is the data obtained and managed? SEC filing data collection is done in-house and is entirely automated with little to no human intervention. 

Because of this, there is a margin for error, and Whalewisdom does advise that users take and use the information at their own risk.
