Based on the most helpful WSO content, here's a breakdown of what you should know about these direct lending firms:

1. Culture

  • Sixth Street: Known for being highly competitive and intense, with a strong focus on performance. The culture leans towards being more institutional and fast-paced, given its size and reputation.
  • Golub Capital: Generally regarded as having a collaborative and professional culture. It's a well-established player in the direct lending space, and the environment is often described as more balanced compared to some of the larger, more aggressive firms.
  • Whitehorse: As part of H.I.G. Capital, the culture can vary by team, but it’s often described as entrepreneurial and hands-on. It’s a smaller platform compared to Golub or Sixth Street, which can mean more responsibility but also potentially less structure.
  • Twin Brook: Known for its middle-market focus, the culture is often described as collegial and team-oriented. It’s a smaller shop compared to the others, which can mean a more tight-knit environment.

2. Compensation

  • Sixth Street: Compensation is typically at the higher end of the spectrum, especially for top performers. Expect competitive base salaries and bonuses, often rivaling private equity pay.
  • Golub Capital: Solid compensation, though slightly below the top-tier firms like Sixth Street. Bonuses are performance-driven and can be lucrative for high performers.
  • Whitehorse: Compensation is generally competitive but may not match the larger players like Sixth Street or Golub. However, the entrepreneurial nature of the firm can lead to unique upside opportunities.
  • Twin Brook: Compensation is solid for the middle-market space, with a focus on work-life balance. It may not match the larger players in absolute terms but is often considered fair for the lifestyle.

3. Strategy

  • Sixth Street: Focuses on opportunistic and flexible capital solutions across the capital structure. They are known for taking on complex, bespoke deals and have a reputation for being aggressive in their approach.
  • Golub Capital: Primarily focused on middle-market direct lending, with a strong emphasis on sponsor-backed transactions. They are a leader in this space and have a well-established platform.
  • Whitehorse: Focuses on middle-market and lower-middle-market lending, often targeting more niche or opportunistic deals. They are known for being flexible and creative in structuring transactions.
  • Twin Brook: Specializes in middle-market sponsor-backed lending, with a strong focus on building long-term relationships with private equity firms. Their strategy is more relationship-driven and less opportunistic compared to Sixth Street.

Final Thoughts

  • If you're looking for a high-intensity, high-reward environment, Sixth Street might be the best fit.
  • For a more balanced culture with strong middle-market exposure, Golub Capital is a great option.
  • If you prefer a more entrepreneurial and hands-on approach, Whitehorse could be appealing.
  • For a collegial, middle-market-focused environment with a better work-life balance, Twin Brook is worth considering.

Each firm has its strengths, so your choice should align with your career goals, risk tolerance, and preferred work environment.

Obligatory I have never worked at any of these firms, nor have I ever worked in lending. 

With that said, Golub has one of the highest satisfaction rates of any company ever. I believe last year they literally had 99% satisfaction, and iirc, all employees have to fill out the survey. I think they also have some insane metrics like no employee turnover in the last 6 months. They are also known for outpaying their competition. Golub is the #1 private credit firm in the world from a market share perspective. If you have traction there, I would encourage you to explore it. 

Someone I know very closely works there, and wont leave until they retire.

Re-reading my comment, I should have noted the person I know there is not in their traditional finance or investing arm (they are middle office). With that said, it doesnt change any of the above. Relatedly, I actually remember being a student and listening to a 2 hour presentation from someone in their lending team, and they spoke extremely highly of the firm and opportunity, going above and beyond what they were expected to say (i.e., they actually appeared to mean it). 

Golub is an extremely private company and I want to be careful not to share too much, but when you work for a private company it is very easy to pay above market comp if you excel at what you do. The culture is also pretty strong. People are intelligent and kind. And the leadership is brilliant. So the business performs. Consistently. 

I know this is rather vague but when a company 1. Pays above market, 2. Develops a unique and strong culture and keeps the assholes out, and 3. Outperforms the market, that is usually a great place to work. Further, don't underestimate the value in working for truly brilliant minds. They are a market leader for a good reason. 

Do some digging into the Golub founders (two brothers), and much of what I said above should easily be validated. 

Great private companies look to fly below the radar in many senses, Golub looks to prioritize discretion over "prestige". I find tremendous value in this approach as I work for an organization that has a very similar approach. Private companies that become market leaders are unicorns, and there is always something special about it. In a world where private equity wants to get their grubby disgusting fingers on every single high performing asset, to work for a company that generates billions at high margins while still remaining truly independent is no small thing. 

 

Agree that WhiteHorse is a sweatshop. While they do look at harder deals (which could be fun), that doesn't mean they are good deals; just pull up a stock price comparison of GBDC, TSLX, and WHF.

I'd probably go Sixth Street if you want best blend of intellectually challenging / skill development while still getting paid well, and Golub if you want more vanilla but market leader / giant in the space with good culture and top of market pay

 

I would pump the breaks on the above regarding golub. Good pay yes, but historically it was known to be sweaty from the investment team side with lots of analysis, only to then turnaround and bend over to give sponsors 10x ebitda leverage at all time tights for anything remotely touching enterprise software up until last year. My example is tongue in cheek, but you get the point. Lots of analysis to put out market clearing paper with docs that have gaping holes in them like most mid-large cap sponsor deals these days. Golub has also been adding new titles and role, delaying career progression (they have senior associates, AVP’s, vice presidents, senior vice presidents and principals)

Sixth street is known to be sweaty as well, but they will do interesting deals that others will shy away from given the complexity. If you go here would be easier to lateral to other places given the depth of training / experience you’d get.

Whitehorse tries to play in this same camp as sixth street as well, but they have a worse reputation in the street in terms of ability to execute. Seen them do some questionable things in the name of deployment.

Twinbrook is below all of the above for the prior mentioned reasons in this thread.

 

Having actually worked at one or more of the firms listed, here are a few insights:

  • None of these 4 are "sweatshops." If you are coming from banking, you would see an improvement in hours at each one of these firms.  Now, there may be a ramp up period where you are "drinking from the firehose," but once that subsides it will be a much better balance.  Not a cake walk, some weeks will be tough, but overall a marked improvement.  I think I have been at a happy hour before where there was someone from all four of these firms!
  • There is generally a trade off between pay and career advancement opportunities. Golub has the best pay but narrowest path up the chain, exact opposite for Twinbrook.  WhiteHorse and SS are in the middle.
  • HIG WhiteHorse and Sixth Street you will have a much more diverse and interesting set of deals, including some middle of the fairway stuff and more opportunistic stuff.  You'll develop a very good skill set. Both are very well respected.  
  • Golub will be much more vanilla deals, but you'll have a top brand. It is highly respected in PC.  
  • Twinbrook is changing a little post-TPG, so may be getting more diverse.  Brand appears to be improving.  
  • BDC performance is not indicative of portfolio health. That said, do ask questions about the platform. None of these 4 strike me as being TMT overweight, but i know Golub does a lot in the space but is probably well-diversified. Do your diligence people!
