Arch Raises $52M In Series B Funding Round Led By Oak HC/FT

Arch was co-founded by Ryan Eisenman, Joel Stein, and Jason Trigg to address the administrative inefficiencies in private investments, such as manual data collection from disparate fund portals. The platform aggregates communications, documents, and data into a unified view, enabling stakeholders—investors, advisors, accountants, and allocators—to focus on strategy rather than operations. It supports private equity, hedge funds, venture capital, real estate, and direct holdings, with features like AI-powered summaries of investor letters and portfolio look-throughs for underlying assets (e.g., exposure to companies like Stripe or SpaceX).

The company’s growth has been fueled by the expansion of alternative investments, which now represent trillions in assets under management globally. Arch’s open API allows integration with existing wealth management systems, differentiating it from competitors like CAIS or iCapital, which focus more on asset origination rather than end-to-end administration.

Details of the Latest Series B Round: Arch closed a $52 million Series B funding round, its largest to date. This brings the company’s total funding to over $77 million. The round was led by Oak HC/FT, a $5.3 billion venture firm focused on healthcare and fintech, with participation from existing investors Menlo Ventures, Craft Ventures, and Quiet Capital, as well as other undisclosed backers.

Valuation and Terms: Specific valuation details were not disclosed in announcements, but the round’s size—more than double the prior Series A—signals a premium on Arch’s growth trajectory. It was structured as traditional equity financing, emphasizing product development over rapid scaling.

Lead Investor Perspective: Matt Streisfeld, partner at Oak HC/FT, highlighted Arch’s “consumerized feel” in a market where private investments often involve fragmented portals and manual processes. He noted the platform’s appeal as private markets attract new entrants, including retail-adjacent wealth advisors, amid assets swelling to tens of trillions.

Use of Proceeds: The capital will primarily fund product enhancements and team expansion. Key priorities include:

• Developing tools for capital calls, distributions, and secondary market transactions to create a “Schwab for private markets.”
• Scaling institutional-grade features like real-time fraud detection and advanced analytics for family offices and private banks.
• Supporting global growth, with a focus on integrating with more fund administrators and GP portals.

This aligns with Arch’s post-Series A momentum, where assets under platform grew from $60 billion in 2023 to over $250 billion by mid-2025, a 4x increase in 14 months.

Previous Funding Rounds

Arch’s funding path demonstrates consistent traction in a competitive fintech landscape.

• Seed Round (December 2021): $5.5 million led by Craft Ventures, with participation from Animal Capital, Good Friends (founders of Warby Parker, Harry’s, and Allbirds), Vine Ventures, Soma Capital, Henry Ward (Carta CEO), and over 25 early clients. The funds supported initial platform build-out, API integrations (e.g., Addepar), and hiring in engineering and operations. At the time, Arch tracked $10 billion in assets and reported 1,100% annualized recurring revenue growth.
• Series A Round (November 2023): $20 million led by Menlo Ventures, with follow-on from Craft Ventures and Quiet Capital, plus new investors like Carta, Citi Ventures, GPS Investment Partners, and Focus Financial Partners. Individual backers included founders of Altruist, Vanilla, Aduro Advisors, Equi, and Sydecar, as well as Gary Cohn (IBM vice chairman) and Scott Prince (Merchant executive chairman). Proceeds expanded the team from 5 to 60 employees and added AI summaries and tax validation features. Post-round, assets hit $100 billion by July 2024.

Investor Landscape and Strategic Backing

Arch’s investors blend fintech specialists, wealth management incumbents, and tech entrepreneurs, providing both capital and strategic value:

• Oak HC/FT (Series B lead): Focuses on fintech scaling; sees Arch as key to democratizing alts for advisors.
• Menlo Ventures (Series A lead): Emphasized Arch’s data infrastructure for upstream integration with GPs.
• Craft Ventures and Quiet Capital: Early believers in operational automation for high-net-worth clients.
• Corporate and Strategic Investors: Carta (equity management), Citi Ventures (banking tech), Focus Financial (RIA aggregator), and GPS Investment Partners (wealth advisory) bring domain expertise.
• Angel and Founder Backers: Ties to fintech successes (e.g., Altruist for custody, Sydecar for syndicates) validate Arch’s workflow focus.

No major investor conflicts or controversies were noted; the syndicate reflects broad alignment on private markets’ growth.

Company Growth and Market Impact

Since the Series A, Arch has achieved key milestones:

• Asset Growth: From $100 billion (2024) to $250 billion (2025), serving 450+ clients including four major private banks and seven of the top 25 accounting firms.
• Client Base: Expanded to RIAs, family offices, institutions, and UHNW individuals; partnerships with RSM US (tax/consulting), Masttro (wealth visualization), and Ultimus LeverPoint (data management).
• Product Innovations: AI-driven insights, portfolio look-throughs, Arch Search (document querying), and capital workflow engines. These reduce manual time by up to 35%, per client feedback.
• Market Context: Alternatives now comprise 20-30% of advisor portfolios, but admin burdens persist. Arch’s neutral aggregator model (capturing any GP/LP structure) positions it against TAMPs like eMoney or SEI’s new alts marketplace.

Challenges include data privacy in private markets and integration with legacy systems, but Arch’s API-first approach mitigates these. CEO Ryan Eisenman describes the platform as automating “everything except advice,” enabling advisors to scale without hiring.

With the Series B, Arch aims to evolve into a full-service private markets hub, potentially adding secondary trading and advanced AI for predictive analytics. Research suggests continued VC interest in alts tech, with 2025 funding up 15% year-over-year amid interest rate stabilization. However, the evidence leans toward moderated growth if economic volatility persists, as institutional allocators prioritize liquidity. Arch’s trajectory seems likely to solidify its role in a market projected to reach $20 trillion by 2030, though competition from incumbents like BlackRock’s alts tools could intensify.

Arch operates as a comprehensive digital platform designed to streamline the administration of private alternative investments, a sector characterized by fragmented data sources and manual processes. Founded in 2018 by Ryan Eisenman (CEO), Joel Stein, and Jason Trigg—drawing from Eisenman’s experience as an investment advisor and the co-founders’ engineering backgrounds—the company addresses core pain points for limited partners (LPs), general partners (GPs), advisors, and service providers. These include collecting K-1 tax forms, managing capital calls and distributions, tracking performance metrics, and aggregating unstructured data from PDFs and portals.

The platform’s core value proposition lies in its ability to standardize communications, documents, and data across investments in private equity, hedge funds, venture capital, real estate, and direct private holdings. By pulling data from fund administrator portals, GP systems, and emails into a single dashboard, Arch enables users to view structured insights—such as cash flows, unfunded commitments, and underlying portfolio exposures—without logging into multiple sites. Features like AI-generated summaries of lengthy investor letters, EIN tax validation, and portfolio look-throughs (e.g., aggregated exposure to unicorns like SpaceX across funds) empower strategic decision-making. Curated permissions ensure secure collaboration among stakeholders, including accountants and allocators, while reducing fraud risks through automated validation.

Arch’s growth has been propelled by the explosive rise of alternative assets, which have outpaced public markets for over a decade, now comprising tens of trillions in global AUM. Investors, particularly high-net-worth individuals and institutions, face increasing complexity as alts allocations grow to 20-30% of portfolios. Traditional tools like Excel or siloed portals fall short, leading to 35% time savings for users, per internal metrics. The platform integrates with leading systems like Addepar, Black Diamond, and APX for reporting, and its open API facilitates embedding into wealth management stacks, distinguishing it from origination-focused platforms like CAIS or iCapital.

Evolution of Funding Strategy

Arch’s funding journey reflects a deliberate progression from product validation to market dominance in alts administration.

Seed Round (December 2021: $5.5 Million): This initial raise, led by Craft Ventures (founded by David Sacks of PayPal and Yammer fame), validated Arch’s MVP amid the post-pandemic alts boom. Participants included Animal Capital (animal welfare-focused VC), Good Friends (a syndicate of Warby Parker, Harry’s, and Allbirds founders), Vine Ventures, Soma Capital, and Carta CEO Henry Ward, alongside 25+ early clients who provided both capital and beta testing. The round emphasized engineering hires to build API connectivity and data aggregation, targeting a lean team of 10. At launch, Arch managed company updates, taxes, capital calls, and statements for a dashboard view, achieving 2,300% growth in private assets tracked and 1,100% ARR increase within months. Plans included expanding to institutional clients like endowments and pensions.

Series A Round (November 2023: $20 Million): Led by Menlo Ventures (backers of Uber and Pinterest), this round scaled operations as alts interest surged among RIAs and family offices. Existing investors Craft and Quiet Capital rejoined, joined by Carta (cap table software), Citi Ventures (Citi’s VC arm), GPS Investment Partners (wealth firm), and Focus Financial Partners (RIA platform). Strategic angels included Altruist (custody), Vanilla (brokerage), Aduro Advisors (fund admin), Equi (alts platform), and Sydecar (venture syndicates) founders, plus IBM’s Gary Cohn and Merchant’s Scott Prince. The capital doubled the team to 60, funding AI tools (e.g., document summaries) and fraud prevention. Croom Beatty of Menlo praised Arch’s “digital backbone” for upstream data integration. Post-round, clients grew to 270+, including four of the world’s largest investment banks, with assets hitting $100 billion by July 2024—a milestone announced alongside hires like a new head of product.

Series B Round (September 15, 2025: $52 Million): The latest infusion, led by Oak HC/FT (investors in Toast and Anduril), underscores Arch’s maturity in a maturing alts ecosystem. Menlo, Craft, and Quiet participated again, with additional support from prior backers. No new major names were highlighted, but the syndicate’s continuity signals sustained belief. CEO Eisenman called it fuel for “modern infrastructure private markets deserve,” aiming to handle capital workflows and secondaries. Assets have since quadrupled to $250 billion, serving 450+ allocators globally, including seven of the top 25 accounting firms. Streisfeld of Oak noted the platform’s user-friendly design for onboarding new alts investors.

Total funding now exceeds $77 million, with no debt components reported. Valuations remain undisclosed, but multiples appear stable (e.g., ARR-based at ~50x in analogous fintechs), reflecting prudent scaling over hype-driven growth.

Strategic Investors and Their Rationale

The investor base is a mix of fintech natives and industry incumbents, providing tactical advantages:

• Oak HC/FT: Targets scalable fintech; views Arch as essential for alts’ “democratization” amid advisor adoption.
• Menlo Ventures: Attracted to data infrastructure; Beatty emphasized connecting GPs for real-time insights.
• Craft Ventures: Early anchor; Sacks’ ops expertise aligns with Arch’s automation ethos.
• Quiet Capital: Focuses on enterprise software; supports long-term R&D.
• Carta and Citi Ventures: Bring equity/tech and banking integrations; Carta’s involvement aids cap table syncing.
• Focus Financial and GPS: RIA/wealth ties; Chang of Focus lauded alts efficiency for HNW portfolios.
• Angels: Founders from Altruist et al. offer peer validation; Cohn’s policy/finance background adds credibility.

This syndicate avoids dilution from over-reliance on one firm, fostering diverse partnerships (e.g., RSM for tax, Masttro for visualization).

Operational and Product Milestones

Post-Series A, Arch launched:

• AI Insights: Summarizes investor letters and Q4 reports in daily “Arch Digest” newsletters.
• Portfolio Look-Throughs: Aggregates fund holdings (e.g., Stripe valuations across managers).
• Arch Search: Keyword queries across documents and dashboards.
• Capital Workflow Engine: Automates calls/distributions, reducing errors.
• EIN Validation: Streamlines tax prep, making deadlines “a breeze” per RIA rep Liz.

Client testimonials highlight impact: Family office advisor Brendan noted avoiding two hires; investor Gary called it “extraordinarily liberating.” Partnerships with RSM (integrating into FamilySight) and Ultimus enhance middle-market reach. By 2025, Arch serves thousands of families/institutions, with 175+ RIAs and UHNW users.

Competitive Landscape and Market Dynamics

Arch competes in a crowded alts tech space:

• Direct Rivals: Canoe Intelligence (data extraction), eMoney Advisor (wealth tools with alts add-ons).
• Broader Competitors: SS&C Advent (portfolio mgmt), SEI’s Apex Alts (marketplace), Addepar (reporting, but less admin-focused).
• Differentiation: Neutral aggregator for any private structure; AI for unstructured data; advisor-client dual interface.

The alts market, valued at $13-18 trillion in 2024, grows 10-15% annually, driven by diversification needs. Challenges include regulatory scrutiny (e.g., SEC on alts disclosure) and data silos, but Arch’s API mitigates these. Economic factors like rate cuts could boost inflows, though volatility might temper institutional risk-taking.

Risks and Opportunities

Opportunities abound in alts’ expansion to mass affluent via advisors, with Arch poised for secondary trading features. Risks include integration hurdles with legacy systems and competition from Big Tech (e.g., BlackRock’s alts portal). Balanced views from sources suggest Arch’s focus on admin—vs. origination—insulates it, with evidence leaning toward sustained demand as alts AUM hits $20 trillion by 2030.
In summary, the Series B cements Arch’s leadership in private markets digitization, building on a proven track record of innovation and growth.
