Ask someone what Blackstone does and most people say buyouts: leverage, exits, the largest private equity firm in the world. That description stopped being complete some time ago, and most applicants never find out.
At 30 June 2026, Blackstone's largest business by assets was not private equity. It was credit and insurance — a division most candidates have never heard called by its own name, because for most of its life it did not have one.
Blackstone Credit & Insurance at a glance
| Formed | 13 September 2023, merging corporate credit, asset-based finance and insurance |
| Predecessor | Blackstone Credit, renamed from GSO on 9 November 2020 |
| GSO's origin | Founded 2005; acquired by Blackstone in March 2008 for roughly $1bn |
| BXCI assets | $469.3bn at 30 June 2026, Blackstone's largest of four segments |
| Fee-earning AUM | $318.2bn, 33% of Blackstone's firmwide fee-earning AUM |
| Global Head | Gilles Dellaert, since BXCI's formation |
| Head of International | Dan Leiter, appointed April 2024, based in London |
| Structure | Corporate credit and direct lending, Infrastructure & Asset Based Credit, Liquid Credit Strategies/CLOs, and insurance |

Every figure above comes from Blackstone's own filings and press releases, dated because each will move.
The angle: the arm is now the body
Most candidates arrive expecting a buyout-first firm with a credit arm attached. By assets, the arm is now the largest of the four.
Private equity is still the business Blackstone is famous for. Credit and insurance is now the business it is largest in, on both total assets and the share of assets that actually generate fees: 33% of the firm's fee-earning AUM sits inside BXCI, more than any other segment.
That ordering is not a rounding error. It is the reason a lending seat at Blackstone is a seat inside the firm's biggest engine, not its side business — and it is the single most useful fact to have ready when a fit round asks why credit rather than the private equity job everyone else is chasing.

Never write GSO
This is the fastest way to sound out of date in the room, and it is an easy mistake to avoid once the timeline is straight.
GSO (dead since 2020)
- Independent-feeling credit boutique, founded 2005
- Named for founders Goodman, Smith and Ostrover
- Corporate credit only, roughly $9.6bn at acquisition
- All three founders have since left the firm
Blackstone Credit & Insurance (today)
- Fully integrated Blackstone division
- Sole Global Head: Gilles Dellaert
- Corporate credit, asset-based finance and insurance combined
- $469.3bn at 30 June 2026, Blackstone’s largest segment
The chain runs in three clean steps:
- 2005 — Bennett Goodman, Tripp Smith and Doug Ostrover, formerly of leveraged finance at Donaldson, Lufkin & Jenrette and then Credit Suisse First Boston, found GSO Capital Partners.
- March 2008 — Blackstone acquires GSO for roughly $1bn. At the time it manages $9.6bn and employs fewer than 150 people.
- 9 November 2020 — GSO is retired as a name. The unit becomes Blackstone Credit, by then $135bn and 350-plus people.
- 13 September 2023 — Blackstone Credit merges with the firm's asset-based finance and insurance groups to form BXCI.
All three GSO founders are gone. Smith left in 2018 to pursue other opportunities, and Ostrover had already left in 2015 to go on and co-found what is now Blue Owl Capital, a large, listed direct lender in its own right. Goodman, the last to remain, retired at the end of 2019.
Neither GSO nor Blackstone Credit describes anything current, and a candidate who uses either has said something about how recently they researched the firm.
From a credit boutique to Blackstone's biggest segment
Combined credit and insurance assets at formation against the same measure at 30 June 2026. Both figures are Blackstone's own.
At formation, Blackstone described credit and insurance as its fastest-growing segment, having more than doubled over the prior three years. That framing held for a while and then stopped being quite true: by the second quarter of 2026, multi-asset investing was growing faster in percentage terms (21% year over year against BXCI's 15%), even though BXCI remains far larger in dollars. Growth rate and scale are different questions, and a candidate who conflates them will get corrected by an interviewer.
The more durable fact is inflows. BXCI took in $31.0bn in the second quarter of 2026 alone, and carried roughly $84bn of dry powder against future deployment — capital raised and waiting, which is a better read on near-term hiring than any single quarter's growth percentage.

What's actually inside BXCI
"BXCI" is a banner over four separate businesses, each with its own leadership and its own hiring line. Knowing which one a role sits in matters more here than the umbrella name.
| Business | What it does | Who runs it |
|---|---|---|
| Corporate credit / direct lending | Senior secured loans to sponsor-backed companies, the largest single business | Reports through Dellaert; Dominic Ashcroft heads European origination |
| Infrastructure & Asset Based Credit (IABC) | Asset-based finance, infrastructure credit, residential real estate lending | Robert Horn, Global Head |
| Liquid Credit Strategies (LCS) | Corporate bonds, leveraged loans, CLOs and multi-asset credit, $120bn | Laura Coady, Global Head of CLOs and European Head of LCS |
| Insurance | Investment management for insurance clients, mostly investment-grade private credit | Philip Sherrill, Global Head of Insurance |
Corporate credit is still the core
Direct lending inside BXCI is the business most candidates picture when they think "Blackstone credit": senior secured loans, sponsor relationships, a deal team underwriting a company's ability to service debt. It is the largest of the four, and the one with the deepest bench of London hiring.
The other three are not afterthoughts
Infrastructure and Asset Based Credit is where a lot of the platform's growth is coming from, because it lends against pools of assets — leases, receivables, infrastructure cash flows — rather than corporate earnings, which behaves differently through a cycle.
Liquid Credit Strategies trades rather than originates, and just set a record year for CLO issuance; Laura Coady, who joined in November 2025 to run it in Europe, came from leading international securitised markets and global CLOs at Jefferies. Insurance is neither of those: it manages assets on behalf of insurance clients, which is a relationship business as much as an investing one.
A junior lands inside real institutional weight either way. BXCI investment professionals average more than 20 years of experience, and the wider Blackstone platform gives the business access to over 100 senior advisors and 50 data scientists — resources that ordinarily sit behind a firm's oldest, most established line, not its newest one.

Interview levelInfrastructure and Asset Based Credit sits alongside corporate credit inside BXCI. What actually separates the two?
The insurance leg, and why it isn't a sidecar
Insurance was one of the three businesses folded into BXCI at formation, alongside corporate credit and asset-based finance, and it is easy to underrate because it sounds like the least glamorous of the three.
It should not be underrated. BXCI describes itself as a leading provider of investment management services for insurers, built specifically on investment-grade private credit capabilities — a different skill set from underwriting a leveraged loan, closer to asset-liability matching than deal-by-deal credit selection. A junior who lands here is doing genuinely different work from a junior on the direct lending desk, not a lesser version of the same job.
The insurance relationship also explains part of why BXCI grew so fast after formation: insurers hold long-dated liabilities and want long-dated, investment-grade assets to match them, and a platform BXCI's size can manufacture those assets at scale in a way a smaller manager cannot.
The lending side runs on the same "capital partner, not just capital provider" idea. BXCI's Value Creation Program, which helps portfolio companies with procurement, cybersecurity and operations, delivered over $1bn of value to those companies in 2025 — the third year running it has cleared that mark. It is a detail worth having ready, because it answers a fit question ("what does Blackstone actually do beyond writing a cheque") with something concrete rather than a slogan.
Who runs BXCI now
Leadership changed meaningfully in the two years after formation, and the current picture is worth having straight before a fit conversation.
- Gilles Dellaert — Global Head of BXCI since formation in 2023, previously Global Head of Blackstone Insurance. Joined Blackstone in 2020.
- Dwight Scott — named BXCI's Chairman at formation, after 16 years at Blackstone. Retired in August 2024. No successor chairman has been named; Dellaert now runs BXCI alone.
- Dan Leiter — Head of International since April 2024, reporting to Dellaert, responsible for EMEA and APAC.
- Michael Carruthers — Head of Private Credit in Europe, appointed the same day as Leiter.
- Robert Horn, Laura Coady, Philip Sherrill — global heads of IABC, Liquid Credit Strategies, and Insurance respectively.
- Michael Zawadzki — Global Chief Investment Officer for BXCI, working alongside Kenneth Caplan, Blackstone's firmwide Global Co-Chief Investment Officer.
Scott joined the firm's credit business in 2008, built it through the GSO-to-Blackstone-Credit transition, and became BXCI's chairman at launch — then retired eleven months later. Dellaert has run the combined business alone since, with Leiter's international appointment arriving the same year as the leadership handover.

Warm-upDwight Scott was named BXCI's chairman when it launched in 2023. What is true of BXCI's leadership today?
The London push
Leiter's appointment is the detail worth remembering, because it tells you where BXCI is trying to grow. His mandate, reporting directly to Dellaert, covers Europe, the Middle East and Asia-Pacific specifically — a dedicated international leadership layer that did not exist before April 2024.
Two things follow from that for a London-based candidate:
- International is a genuine growth priority, not a satellite office. A named head reporting to the global head is a structural signal, not a press-release courtesy.
- The Europe appointment went to an internal promotion, not an outside hire. Michael Carruthers, named Head of Private Credit in Europe the same day as Leiter, had already been co-chief investment officer of BXCI's European and APAC private credit businesses — continuity in the team running the desk, change only at the top.
- Coady's arrival in November 2025 reinforced the same pattern. She joined specifically to expand the CLO franchise across Europe, on top of an LCS business already managing $120bn globally.
London is where a junior candidate should expect the platform to keep adding seats, and it lines up with what the job postings actually show.
Where the junior seats actually are
At the time of this research, BXCI had at least three distinct live 2027 Summer Analyst requisitions in London, each a separate ten-week programme rather than a single generic "credit" internship:
- Private Credit Strategies — the direct lending desk, European transactions, portfolio analysis.
- Infrastructure and Asset Based Credit — the asset-based finance and infrastructure business Robert Horn leads globally.
- Quant and Portfolio Analytics — a programming- and modelling-heavy seat, distinct from the deal-team roles above.
Additional 2027 BXCI Summer Analyst reqs sit in New York, spanning insurance, the Chief Investment Office, and Liquid Credit Strategies — a reminder that "which team" is a real early question everywhere in BXCI, not just in London.
Eligibility is standard across the London programmes: current undergraduate or master's enrolment, an anticipated graduation date of Summer 2027 or 2028, and a CV submitted directly through the posting rather than forwarded from a generic recruiter inbox.
The process: pymetrics, a video round, and the maths of 0.3%
This is the part of BXCI's hiring that catches credit candidates off guard, because it front-loads two automated stages before anyone reads a resume closely.
What comes before a human interview
Blackstone's own materials describe the sequence plainly: a resume, then a pymetrics assessment of twelve short games measuring traits like risk tolerance and decision-making, then a short pre-recorded video interview. Only after both of those does a live conversation happen. Candidates describe this sequence applying across Blackstone's analyst and associate pipelines, credit included, ahead of a multi-interview Superday whose length and structure vary by team.
That is an unusually mechanical front end for a credit seat, where the eventual job is reading term sheets and judging management teams — not playing games. The practical implication is straightforward: the first real signal a candidate sends Blackstone is behavioral and automated, so treating the pymetrics stage as a formality is the most common early mistake.
Candidates who make it through both automated stages describe a Superday: several back-to-back interviews in one day, mixing motivation questions with technical ones. Length and format are reported to vary by team — one credit candidate described a roughly four-hour block, against a shorter, more rounds-based format described for other business lines. Treat that variation as normal rather than as a signal something has gone wrong.
The number worth getting right
Blackstone itself has stated a first-year analyst acceptance rate below 0.3%, drawn from a year in which 169 positions were filled from 62,000 applicants. It is worth being precise about what that number covers: it is a firm-wide analyst figure, not something specific to credit or to BXCI. No BXCI-specific rate has ever been published.
Test yourself
Interview levelA candidate says "0.3% is BXCI's acceptance rate for credit hires." What is the precise problem with that claim?
What a junior actually does
The honest answer depends entirely on which of the four businesses a candidate lands in, which is why asking "which team" early is worth more than any amount of general BXCI trivia.
On the corporate credit desk, the work is underwriting and monitoring: building the model, reading the credit agreement, sitting in on diligence calls, then tracking covenant compliance on a book of borrowers once the deal closes. On IABC, the unit is underwriting a pool of assets rather than a single company, so the analysis leans on collateral performance data more than management interviews.
On Liquid Credit Strategies, the rhythm is closer to trading: relative value across instruments that already exist in the market. On insurance, the work is closer to asset allocation against long-dated liabilities than to deal-by-deal credit picking.
- Corporate credit: model-building, covenant analysis, deal diligence, ongoing monitoring.
- IABC: collateral and cash-flow structuring across asset pools rather than single companies.
- Liquid Credit Strategies: relative value, CLO structuring, market technicals.
- Insurance: portfolio construction against long-dated liabilities, less deal-driven.
Monitoring is worth taking seriously rather than skipping past in an answer. A book of borrowers needs quarterly covenant checks long after a deal closes, and it is where a junior actually learns what breaks a credit — the same instinct behind the Value Creation Program's procurement and operations work, which only makes sense once a loan has already been made and the relationship keeps going.
How to prepare for BXCI specifically
- Get the naming history right. GSO, then Blackstone Credit, then BXCI — say the current name and know why the older ones are wrong.
- Pick a business and be able to defend it. "I want to work in Blackstone credit" is not an answer when there are four distinct businesses under that banner.
- Treat pymetrics and the video round as real stages, not formalities to click through, since they filter before any human reads a full application.
- Know the AUM ordering. Credit & Insurance is Blackstone's largest segment, ahead of private equity — the single most surprising true fact available to open with.
- Have a view on where BXCI is growing. International, under Dan Leiter, and asset-based finance, under Robert Horn, are the two clearest expansion stories to reference.
- Use the 0.3% figure precisely. It is a firmwide analyst statistic, not a BXCI-specific one, and saying so correctly is itself a small signal of care.
Test yourself
Warm-upA candidate answers "why BXCI" with "it's the biggest name in credit." Why is that a weak answer?
The bottom line
The opening fact carries the whole guide: the business Blackstone doesn't lead with in conversation is the one it is now largest in. BXCI got there by merging three businesses in 2023, shedding a name most candidates still reach for by habit, and adding international leadership within a year of a chairman's departure.
None of that shows up if a candidate walks in describing GSO, or treating BXCI as a single credit desk, or reciting 0.3% as though it were a credit-specific figure. Get the naming, the structure and the scope of that number right, and the rest of the preparation is standard credit ground: pick a business, know why, and be ready to defend it.
