Weekly update: K1x, an AI-native tax data platform for private markets, raised $175M

We’re launching an experiment. We’ve partnered with Rob Saunders, CEO, WhoFiled, to share a weekly update on all material fundraising activity, product launches, and infrastructure developments in the investment tech space. Please share your feedback!

Our coverage definition: U.S. and global investment tech transactions and product activity. We define investment tech as tools, platforms, and infrastructure whose primary buyer is a fund manager, allocator, or financial advisor. This includes deal sourcing and modeling, portfolio analytics, fund administration, LP reporting, compliance and reg-tech, cap table management, alternative data for diligence, and AI tools purpose-built for the investment workflow. Consumer fintech, retail banking, and general SaaS are excluded.

The big theme: private market back-office infrastructure is getting its largest checks yet.

K1x, an AI-native tax data platform for private markets, raised $175M led by Sumeru Equity Partners, with Edison Partners participating for the third time since 2022. Sumeru takes majority ownership. The company automates the extraction, aggregation, and standardization of K-1, K-3, and 1099 data. That sounds mundane until you realize K1x already serves 44 of the 100 largest U.S. institutional investors, 20 of the top 25 accounting firms, and 45 of the largest university endowments. The $27 billion annual burden of private market tax reporting is, as CEO John LaMancuso put it, “no longer seasonal. It’s structural.” The market remains over 90% unserved.

This is the second consecutive week where the largest investment tech raise went to back-office infrastructure rather than front-office tooling. Last week it was GeoWealth ($42.5M from Goldman Sachs for portfolio management and RIA operations). This week it’s K1x ($175M for tax compliance automation). The pattern is clear: the operational layer that most funds still run on spreadsheets and email is where the real money is moving.

Notable investment tech raises

Silk River$1.8MIntelligence layer for financial institutions that coordinates work across existing systemsTargets CIOs and heads of operations. Designed to enhance legacy infrastructure without requiring platform replacement.

On the radar

Beneficient (Nasdaq: BENF) raised $8.75M through a GP Primary Capital transaction, continuing to build out its AltAccess platform for alternative asset liquidity. The public company provides exit opportunities and primary capital solutions to GPs and mid-to-high net worth holders of alternative assets. It operates under a Kansas TEFFI charter (Technology-Enabled Fiduciary Financial Institution), one of the first of its kind. Worth watching as the secondary market for alternative assets matures.

Levelup Intelligence raised $225K for a centralized dashboard that integrates portfolio company financial data from multiple accounting platforms. Early stage, but the problem (scattered financial data across portfolio companies) is universal in PE and VC operations.

Malcolm (aimalcolm.com) also filed this week, building a platform that automates data extraction, reporting, and collaboration for PE, VC, and private credit funds. Another early-stage entrant targeting the same pain point as K1x and Levelup from a different angle. When three companies file in the same week solving variations of the same problem (fund data is fragmented, manual, and hard to report on), the market is telling you something.

The takeaway for your tech stack

K1x’s CEO framed it: “Where tax compliance in public markets runs like a Swiss watch, private markets still run on manual processes, unstructured documents, and fragmented systems that cannot scale.” That’s not just true for tax. It’s true for portfolio reporting, LP communications, fund admin, and compliance. The firms raising the largest rounds right now are all attacking the same gap: the distance between how public market operations work and how private market operations actually run day to day. If your fund’s back office still depends on spreadsheets and email threads, the vendors building the replacement are getting funded at scale. The window to choose is open. It won’t stay that way.

9/19, NYC: Vibe Coding for VCs

Build First and Company Ventures are hosting a half-day, in-person workshop in New York City on Thursday, September 19, from 1–5 p.m. called Vibe Coding for VCs.

This program is designed for venture investors and operating partners who want to get closer to the code behind their portfolio companies and better understand how AI is actually built.

Why attend?

  • AI fluency is a new baseline. Learning AI is less like picking up a new tool and more like acquiring a new language.
  • Hands-on practice. You’ll learn a proven AI design framework (developed with Decoded Futures) that has already been used to build 100+ custom GPTs and 50+ mini-apps.
  • Structured build time. You’ll build something together, then split into an “AI Power Hour” where you’ll create your own faster project, with technical specialists on hand to help troubleshoot.
  • Practical outcomes. You’ll leave with new context on AI architecture, frameworks, and a working build you’ve coded yourself.

Why it matters for VCs
Understanding the builder’s perspective is critical for investors. As AI reshapes how we work, operate, and collaborate, it will also reshape what it means to be a founder—and how VCs assess, support, and fund them. This workshop is a chance to experience that shift firsthand.

Logistics

  • Date/Time: Thursday, Sept. 19, 1–5 p.m.
  • Location: Company Ventures, New York City
  • Hosts: Bethany Crystal (Build First) with Matt Harrigan and Sanice Embleton (Company Ventures)

About the facilitator

The workshop is led by Bethany Crystal, a VC-turned operator with 15 years of experience in tech. She previously worked at Union Square Ventures and Variant Fund, supporting early-stage founders across dozens of portfolio companies. As an operator, she has led strategy, community, and scaling efforts at organizations like the Uniswap Foundation, and Tech:NYC. Today she is the founder of Build First, focused on helping investors and executives gain practical fluency in AI by building.

Registration

You can register through Build First (AI-powered) or Luma (classic)

9/15-9/17, NYC: Single Family Office Forum

Request admission

Curated by Angelo Robles—a family office advisor with over two decades of experience—alongside Alexander Galambos, a leading European family office liaison—this experience is built by families, for families.

I’m honored to be one of the speakers at this curated event. On September 15-17, you’ll experience:

  • Distinguished speakers, including Chris Voss, Former Chief Hostage Negotiator, FBI, Harvard Professor and CEO & Founder, Black Swan Group; Andrew Brenton, formerly CEO of the private equity subsidiary of The Bank of Nova Scotia
  • BATTLE OF IDEAS: One stage. Two perspectives. No safe takes. A real debate.  Battle of Ideas is a face-to-face showdown between two thinkers with radically different views on the issues that matter most to families of wealth, from investing and governance to AI, inflation, geopolitics, and freedom.
  • Actionable strategies you can apply immediately to protect, grow, and evolve your family enterprise
  • A curated circle of world-class families and wealth creators—real operators, not spectators
  • Unfiltered insight into what’s working (and what’s not) from those on the front lines of generational wealth
  • Immersive environments that elevate both the conversations and the connections—from elegant receptions to private family-led sessions

We conclude (September 17th) with an extended private member luncheon at one of New York City’s finest steakhouses—an intimate, high-caliber gathering curated exclusively for our members.

Request admission

Over the course of three hours, we’ll hear directly from top family office investors as they share bold conviction plays across:

  • AI – Breaking down the full stack:
    Chips → Data Centers → Models → Deployment Infrastructure → End Applications.
    We’ll explore where the alpha is—whether it’s NVIDIA and GPU monopolies, cloud-sovereign infrastructure, custom LLMs, or the arms race for deployment into enterprise and consumer ecosystems.
  • Crypto – Including Bitcoin, yield-bearing stablecoins, and the likely future financial rails (yes, we’re talking Ripple Labs)
  • Real Estate – Tactical opportunities in a post-rate-shock landscape
