Private Equity Firms Greenwich CT: Top Firms in 2026

Key Facts

• Fund sizes range from $152 million (Peloton Equity Fund II) to $37 billion, spanning lower-middle-market growth equity to mega-fund consumer buyouts.
• Sector coverage is unusually concentrated: consumer brands, healthcare, financial services, industrials, and lower-middle-market business services each have dedicated specialists headquartered in Greenwich.
• Peloton Equity's portfolio company AeroCare was acquired by AdaptHealth for approximately $1.1 billion in 2021, one of the most significant Greenwich PE exits in recent years.
• Capital is currently concentrating in healthcare services fragmentation, AI-enabled healthcare technology, and lower-middle-market first-institutional-capital opportunities.
• Greenwich firms hold a structural cost advantage: proximity to New York City deal flow and banking relationships combined with operating costs substantially below Manhattan.

Greenwich as a PE Hub: Market Context and Geography

Greenwich, Connecticut sits roughly 45 minutes from Midtown Manhattan, close enough to access the city's deal flow, banking relationships, and limited partner (LP) base without paying Manhattan's cost premium. That combination has made the town one of the densest concentrations of institutional capital outside New York City, hosting both private equity firms and hedge funds such as Viking Global Investors (139 investments, 38 exits) and Lone Pine Capital. The result is a talent ecosystem with unusual depth for a Connecticut suburb.

The Fairfield County ecosystem extends beyond Greenwich proper. Westport-based BHMS Investments targets insurance services platforms in the lower middle market, while firms including Clearview Capital and Heartwood Partners operate from elsewhere in Connecticut. Together, this cluster of 50-plus Connecticut fund managers creates a co-investment and deal-sourcing network that reinforces individual firm activity. KarpReilly and Mill Road Capital, both Greenwich-headquartered, add to the ecosystem at the small-cap end of the market.

Sector concentration is pronounced among leading Greenwich CT private equity firms. Consumer brands dominate the upper tier, anchored by L Catterton's ~$37 billion in AUM. Healthcare growth equity clusters around Peloton Equity and Great Point Partners. Financial services investing is Stone Point Capital's exclusive domain, while industrials and manufacturing are covered by Littlejohn & Co. and Monomoy Capital Partners. Southfield Capital and BHMS fill the lower-middle-market business services and insurance segments.

Top Greenwich CT Private Equity Firms in Detail

L Catterton

The world's largest consumer-focused private equity group, L Catterton manages approximately $37 billion in AUM from its Greenwich headquarters. Its investment thesis spans the full consumer landscape: beauty, food and beverage, retail, fitness, and travel, targeting both middle-market buyouts and emerging high-growth enterprises. Since 1989, the firm has made more than 275 investments and maintains offices in Paris, Singapore, and New York alongside its Greenwich base. It was named Private Equity Firm of the Year five consecutive times from 2015 through 2019. Recent portfolio additions include AmaWaterways (2024) and Alliance Animal Health (2021). Consumer brand founders seeking a capital partner with proven global distribution infrastructure will find no larger dedicated fund in this sector.

Stone Point Capital

Greenwich's financial services specialist manages $35 billion or more in committed capital across its Trident Funds, making it the dominant PE platform for financial services investing in the region. The firm invests exclusively in asset management, insurance, and real estate services companies globally. Its most prominent active holding, Sedgwick, was valued at $13.2 billion when Altas Partners invested alongside Stone Point and Carlyle in September 2024, with Stone Point continuing as an investor. The firm has logged 68 investments and 26 exits, a realization rate that reflects deliberate portfolio construction rather than deal volume. General partners in insurance or asset management seeking a sector-native PE partner with deep industry relationships should treat Stone Point as the benchmark comparison.

Littlejohn & Co.

The strongest operational track record in the Greenwich ecosystem belongs to Littlejohn & Co., which has built its ~$8 billion in regulatory AUM on what it calls an "all-weather" investment strategy: buyouts, carve-outs, special situations, and capital solutions across market cycles. The firm targets North American industrial and services companies and distinguishes itself through an integrated investment-and-operations team with approximately 20-year average partner tenure. Valcourt Building Services completed 10 add-on acquisitions in 15 months under Littlejohn ownership, doubling in size. Kaman Distribution Group's EBITDA grew more than 50% in two and a half years. Two portfolio exits closed in 2025: PlayPower to Platinum Equity and PatientPoint to Advent International.

Alvarez & Marsal Capital

A multi-strategy platform unlike any other in the Greenwich market, A&M Capital deploys $5.9 billion across four distinct vehicles: a $4 billion-plus North American control buyout fund (AMCP), a €650 million European middle-market fund (AMCE), a secondaries vehicle (AMCS), and a co-investment strategy. AMCP targets companies with $20 to $100 million in EBITDA and $150 to $750 million in enterprise value. No other Greenwich firm replicates its structural advantage: direct access to roughly 9,500 professionals at Alvarez & Marsal's global consulting practice. Notable portfolio companies include Allied Universal, ProAmpac, and Crash Champions. ProAmpac entered a $1.51 billion acquisition by TC Transcontinental Packaging announced in December 2025.

Great Point Partners

Healthcare is the only sector Great Point Partners touches. Managing more than $1.3 billion in AUM since its 2003 founding, the firm has completed 34 investments and 24 exits across healthcare services, medical devices, and biopharma. That 71% realization rate is among the highest documented for any named Greenwich firm. A recent strategic expansion added a London office to source European healthcare deals, with Lyocontract, a German contract development and manufacturing organization, serving as the inaugural European transaction. Healthcare company management teams and LPs seeking focused sector exposure with a demonstrated exit record should evaluate Great Point as a primary option.

Peloton Equity

Healthcare growth equity at the lower-middle-market stage is Peloton Equity's singular focus. The firm targets companies with $10 to $200 million in revenue and EBITDA ranging from negative $10 million to positive $10 million at investment, a stage most buyout funds treat as too early. Peloton has completed 26 exits including 5 IPOs, with $900 million or more invested across the team's cumulative history. AeroCare sold to AdaptHealth for approximately $1.1 billion in 2021; Arcadia transitioned to Nordic Capital in 2025. The "Peloton Nation" network of 200-plus healthcare leaders contributes to due diligence on every investment, with an average of nine network members engaged per portfolio company. Healthcare founders operating in the post-venture, pre-buyout stage have no more experienced sector partner in Greenwich.

Southfield Capital

Southfield Capital occupies a precisely defined niche: lower-middle-market business services companies with $4 to $20 million in EBITDA that are receiving their first institutional capital. The Greenwich firm has made 80 or more investments since its 2002 founding, deploying more than $1.5 billion across its fund series, and is currently investing from Fund IV. Its portfolio has included Tier One Relocation (2016), Vanguard Dealer Services (2015), and Hallcon Corporation (2011). Southfield's willingness to take minority positions alongside control investments makes it structurally flexible in ways that pure-buyout funds are not. Entrepreneur-founders who want institutional backing without full sale should compare Southfield directly against Clearview Capital and Heartwood Partners, both operating in an adjacent Connecticut ecosystem.

North Castle Partners

Consumer wellness investing is North Castle Partners' only business. Active since 1997, the Greenwich firm focuses on health, wellness, and active living brands spanning beauty, fitness, specialty nutrition, and food and beverage. With 23 completed exits, including the Curves International fitness franchise expansion, the firm has demonstrated a repeatable model for scaling purpose-led consumer brands over more than 25 years. North Castle does not publish AUM, but its exit count reflects consistent fund activity across multiple vintages. Founders of wellness or fitness brands with strong unit economics seeking a capital partner who understands consumer channels will find a more specialized fit here than at a generalist middle-market buyout firm.

Brynwood Partners

Consumer brand revitalization is Brynwood Partners' defining capability. Operating from Greenwich since 1984, the firm acquires well-known consumer brands it considers operationally underperforming and rebuilds them through product line rationalization and distribution improvements. The Sunny Delight transformation is the most frequently cited proof point, demonstrating Brynwood's ability to restore brand equity through operational intervention. Unlike L Catterton's growth-oriented consumer mandate or North Castle's wellness focus, Brynwood targets brands requiring fundamental operational correction. Consumer companies with recognized brand equity but margin erosion represent the primary investment thesis.

Monomoy Capital Partners

Manufacturing, distribution, and services companies with $20 to $200 million or more in EBITDA and $100 million to $2 billion in revenue form Monomoy's stated deal universe. The Greenwich firm targets sectors including aerospace and defense, building products, food and beverage, and industrials, sourcing from family-owned businesses, corporate carve-outs, and take-privates. Monomoy does not publicly disclose AUM, but its sector breadth and EBITDA floor place it in the core middle market alongside Littlejohn and A&M Capital. Industrial and manufacturing business owners evaluating buyout options should compare Monomoy's sector-specific approach against Littlejohn's cross-cycle "all-weather" flexibility and A&M Capital's consulting integration model.

Investment Trends Shaping Greenwich CT Private Equity

Healthcare Data and AI-Enabled Services

AI-powered healthcare administration is drawing concentrated capital from Greenwich-based fund managers. Peloton Equity's investment in OnPoint Healthcare Partners illustrates the direction: the company launched an autonomous AI practice management platform in October 2025, targeting administrative cost reduction rather than headcount growth. The Arcadia healthcare analytics platform received $125 million in growth financing from Vista Credit Partners in 2023 before transitioning to Nordic Capital in 2025.

Healthcare Services Fragmentation and Consolidation

U.S. healthcare services remain highly fragmented, sustaining consistent deal flow for firms with sector expertise. Peloton Equity has backed rehabilitation, home health, and population health management companies, including ClearSky Health's rehabilitation network launch and a $43 million cold chain pharmaceutical logistics financing round for AeroSafe Global in 2023. Great Point Partners expanded into European healthcare with its Lyocontract acquisition, reflecting confidence that fragmentation-driven consolidation plays exist beyond domestic markets.

Industrial Buy-and-Build Platforms

Littlejohn's Valcourt Building Services completed 10 acquisitions in 15 months, demonstrating how buy-and-build strategies can compound portfolio value faster than organic growth alone. SunSource's expansion under Littlejohn ownership into a North American fluid power leader followed a similar pattern. Monomoy's manufacturing and distribution focus positions it to execute comparable consolidation strategies in aerospace, building products, and food and beverage.

Insurance Services Platform Consolidation

BHMS Investments (Westport, CT) has assembled a lower-middle-market insurance distribution platform through sequential acquisitions: King Risk Partners (July 2021), Innovisk Capital Partners (November 2021), and Boost Insurance (July 2024). The firm raised a new fund in 2024 to continue this strategy. Stone Point Capital addresses the large-cap end of the same structural trend through its Trident Funds, which have made 68 investments in global insurance and financial services.

Lower Middle Market First-Institutional-Capital Opportunities

Southfield Capital's 80-plus investments over 22 years and Clearview Capital's 45 closed deals on Axial demonstrate that entrepreneur-founded, organically grown companies with $4 to $20 million in EBITDA remain an accessible and underserved deal source. Uncommitted capital held by lower-middle-market funds is deploying into business services, specialty distribution, and technology-enabled operations, with multiple Connecticut-based firms actively sourcing in this segment.

How to Evaluate Greenwich CT Private Equity Firms

Match fund size to deal size before any other assessment. Southfield Capital targets $4 to $20 million EBITDA businesses. A&M Capital Partners requires $20 to $100 million EBITDA and $150 to $750 million in enterprise value. Approaching a mid-market buyout fund with a $3 million EBITDA business wastes both parties' time and signals a misunderstanding of how PE funds are sized.

Realized exit track record carries more weight than investment count. Great Point Partners has completed 24 exits from 34 investments. Peloton Equity has 26 exits including 5 IPOs. North Castle Partners has 23 exits. Compare these realization ratios against each firm's current investment count to assess capital recycling velocity and actual portfolio performance rather than stated strategy.

Evaluate operational value-add specificity rather than generic claims. Littlejohn publishes detailed CEO case studies documenting EBITDA growth percentages and acquisition counts. A&M Capital explicitly ties its investment thesis to the A&M consulting platform, providing access to roughly 9,500 professionals. Ask any prospective partner for specific examples of how they improved EBITDA, not just revenue, in portfolio companies.

Verify fund vintage and deployment status when conducting LP due diligence. BHMS raised its most recent fund in 2024 and is actively deploying. Peloton Fund II closed in February 2021. A fund in the middle of its deployment window offers more predictable capital call timing than one approaching the end of its investment period, where uncommitted dry powder may sit idle.

Partner stability matters more in PE than in most institutional asset classes. Littlejohn's approximately 20-year average partner tenure is a meaningful outlier. Key-person risk can significantly affect portfolio performance in middle-market buyout funds where individual partners own deep sector relationships and proprietary deal sources.

Which Firm Fits Your Needs?

Healthcare founders operating at the growth stage, with revenue between $10 million and $200 million and EBITDA near breakeven, should prioritize Peloton Equity and Amulet Capital Partners. Both are Greenwich-headquartered, exclusively focused on healthcare, and experienced with the post-venture, pre-buyout stage that larger buyout funds typically avoid. For healthcare companies already at scale requiring a middle-market buyout partner, Great Point Partners (24 exits from 34 investments, $1.3B+ AUM) is the stronger fit.

Consumer brand operators face a more segmented choice. L Catterton is the right partner for brands targeting global expansion; its 275-plus investments and offices in Paris and Singapore provide distribution infrastructure few PE firms can match. North Castle Partners better serves wellness, fitness, and active living brands seeking a capital partner who understands purpose-led consumer marketing. Brynwood Partners is the specific answer for brand owners whose businesses carry operational inefficiencies obscuring underlying brand equity.

LPs building alternatives portfolios should differentiate by strategy. Stone Point Capital provides concentrated exposure to global financial services, while A&M Capital's four-fund structure offers both North American control buyouts and European middle-market access within a single general partner (GP) relationship. Lower-middle-market allocators should examine Southfield Capital and Clearview Capital, both serving the $4 to $20 million EBITDA segment with 20-plus year track records and active fund deployment.

Industrial and manufacturing business owners considering a sale or recapitalization have three well-resourced options in the Greenwich ecosystem. Littlejohn & Co. is best suited for companies undergoing transformation or corporate carve-outs. Monomoy Capital targets family-owned and take-private situations with $20 million or more in EBITDA. A&M Capital is the strongest fit for businesses where the consulting platform can accelerate margin improvement as part of the investment thesis.
