Thanks, Jono. Starting with Q1, not only did we generate over $1.3 billion of net inflows across the firm with nearly 3x as many funds inflowing and outflowing, but our inflows outpaced negative markets and our AUM grew quarter-over-quarter to new record highs. And this strength has continued in April with net flows of nearly $1.7 billion, taking our global AUM over $80 billion for the first time. And as Jono has already highlighted, a large part of today's success has been the work and investment that has taken place over the past several years.
Starting with Europe, back in early 2018, we closed the ETF Securities transaction. With it, we acquired a commodities franchise and AUM diversity that even today remains largely uncorrelated to the rest of our global product suite. We also got distribution pipes into the relatively walled garden of European wealth management, which is a tough nut to crack from the outside. Post acquisition, with $19 billion of AUM in Europe, we got to work. We invested in team. We improved product structures and pricing, and we purged over 200 subscale funds that were a drag on profitability.
At the same time, we leveraged WisdomTree core competencies to launch new funds and to create new products like UCITS and crypto, which have accounted for all of the organic growth in the European franchise since. All told, we took what could have been merely an accretive deal and we grew it to the over $30 billion in AUM it is today and turn it into a launch pad for future European and global growth.
And at the same time, we were transforming the U.S. business into a broader and more diverse growth engine, making it stronger today than it has been at any other time in our history. We invested in our people to build a best-in-class team across sales, marketing, research, product, operations and corporate functions. We adopted a more robust product innovation process to better define product market fit and increase the odds of a successful traction from new launches. And we launched the WisdomTree managed models initiative that has grown to the point where roughly 12% of flows into U.S. ETFs today come from managed models.
Like our experience in Europe, hard work and investment are paying off, with momentum increasing in 21 of the past 22 months generating inflows. Taken all together, actions we have taken over the last several years have diversified the business and positioned us for long-term organic growth in both the U.S. and Europe. Six straight quarters of firm-wide organic growth and nearly $3 billion of inflows year-to-date would not have been possible without this concerted effort to innovate and improve.
So where do we go from here? I fully expect a continuation of organic growth trends and think we will see accelerated growth for 3 key reasons. First, our product positioning and performance have never been better. Current AUM is levered to investment themes that are flowing and products that are performing. Second, our managed models franchise is entering its third year and its impact on flows is growing. And third, we are first mover in digital assets, which is a natural extension of our core business and has a massive addressable market.
Digging a little further into each. First, our product positioning and performance is outstanding. Over 2/3 of our AUM is currently levered to themes like inflation hedging, rising rates and the rotation from growth to value. Add to that, nearly 80% of our U.S. AUM is in the top 2 quartiles of performance relative to Morningstar benchmarks. With broad and deep inflows and solid momentum, we feel our flows are sustainable and that 2022 could show even better growth than last year.
Second, our managed models franchise continues to gain significant traction. We built this business from scratch with near 0 assets in 2020. Today and very early into our third year, we have over $2 billion in managed model AUM with roughly 12% of our U.S. ETF flows being driven by managed model strategies, which is up from the 10% we reported last year. Here, we have momentum with big partners like Merrill Lynch and Morgan Stanley, and we have won 2 material mandates already this year with others in the pipeline.
On the other end of the spectrum, we also launched WisdomTree Portfolio and Growth Solutions on April 18, which includes customized model construction services in addition to model trading services that will help us grow model flows in the mid- and small RIA market. Overall, we are very excited about the trajectory of our models franchise and we see a long and lucrative growth runway ahead, with the beauty of the models business being that once you win advisor mind share, flows are recurring in nature and stackable on top of our current inflow profile.
Finally, and before I turn it back to Jono, I want to discuss our digital assets opportunity. Jargon like blockchain, crypto, neobank and digital wallets can sometimes be confusing, but our strategy is simple. First, it is to bring crypto exposures into the mainstream financial ecosystem through ETPs and separate accounts. And second, it is to bring mainstream financial assets onto the blockchain and into the digital ecosystem through blockchain-enabled funds and tokenized assets.
Looked at this way, digital assets are a natural extension of what we do, delivering to our clients best structured access to various asset classes. On the first part of our digital asset strategy, bringing crypto exposures to clients in the mainstream wealth ecosystem, we've launched several new crypto ETPs in Europe, including both single exposures as well as baskets. Despite the challenging crypto market, we've continued to see very strong 40% annualized organic growth year-to-date.
While the outlook for a Bitcoin ETF in the U.S. remains muted, even though Bloomberg did recently call WisdomTree the dark horse candidate to gain first approval in 2022, we've also successfully launched a separate account strategy for the U.S. wealth channel. How big is that opportunity? Consider that there are $30 trillion in assets in just the U.S. wealth channel alone. So even a 1% allocation to crypto in just the U.S. would yield a $300 billion market opportunity for crypto exposures, and the realistic opportunity could be multiples of that.
With strong client and advisor demand, we have a clear line of sight towards revenue growth in 2022 that will be even more meaningful in 2023. All in all, our product positioning and performance have never been better. Our models business is gaining traction, and we have first mover advantage and opportunity in digital assets. I'm incredibly excited about the quarters and years ahead, but I've only scratched the surface of the future opportunity.
So let me now turn it back to Jono to discuss the second part of the digital strategy in more detail.
