Guest: Founder of Moment
Host: David Weisburd

Overview of the Episode

In this episode, David Weisburd interviews the founder of Moment, a fintech company determined to modernize and automate the fixed income (bond) market—a $100 trillion global sector long considered technologically behind the stock market. The discussion delves into the massive inefficiencies present in bond trading, the technological revolution underway, how automation benefits institutions and individual investors alike, and how companies like Moment are enabling everything from better tax loss harvesting to scalable portfolio management. The episode also weaves in company-building themes, such as hiring practices and culture, and provides a look at how the industry may evolve, especially for high net worth clients.

Key Discussion Points & Insights

1. Fixed Income Market: Size, Importance, and Legacy Inefficiency

• Fixed income (bonds) market is vast, essential, and technologically lagging:

  • "It's a huge financial market, over $100 trillion...traditionally lagged about 20 to 30 years behind the global stock market." (Founder of Moment, [00:00])
  • The market is critical for everything from public infrastructure to corporate investments.
  • Only in the last decade has electronic trading truly emerged for bonds.

• Legacy trading was manual, inefficient, and opaque:

  • Trading was "basically done completely by hand, over the phone, over Bloomberg chat, etc. The market was generally speaking not very transparent...the least sophisticated users end up getting the worst prices." (Founder of Moment, [06:51])

2. What Moment Does & Why It Matters

• Moment provides electronic infrastructure and automation for bond trading and portfolio management:

  • Develops tools on top of electronic trading infrastructure: trade bonds, manage portfolios, analyze, and conduct compliance.
  • "We build...the full set of tools on top of that core electronic trading infrastructure to enable people in the fixed income market to trade bonds." (Founder, [00:00])

• Customer impact:

  • Started with fintechs; now works with large financial institutions.
  • "We decided to raise a Series B...with amazing partners in Yann Hammer and the entire index team." ([01:44])

• Accessible, tailored fixed income portfolios now possible:

  • Users can enter client needs (e.g., tax situation, investment goals), and receive a customized bond ladder in "five to ten seconds instead of one to two hours." ([11:30])

3. How Bond Market Automation Directly Benefits Investors

• Automation delivers precision, speed, and better pricing:

  • "You could enable [traders] to do things that just were never possible in the fixed income market before." ([04:49])
  • "We enable our customers...to access the fixed income market with best execution across every potential source of liquidity." ([06:51])

• Solving portfolio-building complexity:

  • "At any given time, there are probably about 4,500,000 different bonds...building a portfolio...manually...typically takes about one to two hours. Now...in five to ten seconds." ([11:30])

4. Tax Loss Harvesting and Fixed Income Tax Optimization

• Tax loss harvesting is more powerful with bonds than equities:

  • "In fixed income...you can take advantage of capital losses today without creating and offsetting capital gain for the future." ([13:40])
  • Bonds mature, so you can harvest a loss and not face a future capital gain, unlike with perpetual equities.

• Municipal bonds offer especially pronounced tax benefits:

  • "The amount of tax optimization you can do in the fixed income market...is vastly more than what you can do in the equities market." ([16:00])

5. Trends: From Institutions to High Net Worth & RIAs

• Automation will drive change especially for wealth managers and high net worth investors:

  • "If you're an institutional investor managing 50 fixed income portfolios...that's doable. If you're an asset manager managing 200,000 fixed income portfolios...that is simply impossible without automation." ([18:40])
  • "We might actually see the high net worth and wealth management segment leapfrog some of the institutional segment in terms of automation and technology." ([18:40])

• RIAs and wealth manager consolidation ("roll-ups") create even more need for scalable solutions:

  • Rolling up smaller firms leads to thousands of accounts which cannot be managed manually.

6. Building a Fintech Company: Culture, Talent, and Trust

• Talent bar and hiring philosophy—quality over quantity:

  • "Small teams of genuinely incredible people can massively outperform huge teams of good people." ([23:03])
  • Never lower the hiring bar, even under growth pressure.

• Trust is paramount in financial software:

  • "When we say we are going to do something on this timeline...that is exactly what happens...the most important thing...is maintaining that trust with our customers." ([25:35])

• ‘Build half a product, not a half-ass product’:

  • "Resist the urge to do anything that's not world class." (Interviewer referencing Jason Fried, [25:05])
  • “Your most important currency is the trust that you build with your customers.” (Founder, [25:35])

• In financial software, speed can’t come at the cost of stability:

  • "When something goes into production, we have to be incredibly confident that nothing is going to break." ([27:01])

7. Moment's Customers

• Direct customers: Large wealth management institutions (e.g., LPL Financial, HighTower Advisors).
• End users: Individuals seeking stable, predictable returns—often retirees. ([27:59])

8. Company Growth & Hiring

• Actively hiring across all functions:
  • "We are hiring...looking for incredible people to join us across pretty much every function ranging from...engineering to product to design..." ([29:08])
