Moss Adams Wealth Advisors, the wealth management division absorbed by Baker Tilly in the June 2025 merger of the two accounting firms, announced on March 23, 2026 that it is spinning out as an independent registered investment advisor under the new name Threadline Wealth, with $5.8 billion in client assets and an SEC registration expected in May 2026. The firm is backed by The Cynosure Group, a family-office-funded private investor in wealth management platforms, alongside an employee ownership group, and will be led by co-founder and CEO Justin Fisher, the former national leader of private client services at Moss Adams.
The Seattle-based firm becomes one of the largest RIA spinouts of 2026 and the first major separation from a top-15 accounting firm since Eisner Advisory Group broke from EisnerAmper in 2023. Threadline will keep its existing custodial and wealth technology stack on day one, retain its tax-led service model for high-net-worth families and business owners, and maintain a referral and coordination relationship with Baker Tilly going forward.
The split matters less because of the dollar amount and more because of what it says about a thesis the accounting profession has spent five years promoting: that one-stop tax-and-wealth firms with a CPA backbone could outcompete independent RIAs by integrating compliance, tax planning, and investment management under a single roof. The Threadline announcement is the clearest signal yet that the integrated model has frictions large firms cannot easily resolve, and that the cleaner economic answer is separation.
Key Takeaways
- $5.8 billion in client assets transition with Threadline Wealth, expected to be SEC-registered in May 2026.
- Justin Fisher, former national leader of private client services at Moss Adams, becomes co-founder and CEO. Eric Miles remains CEO of Baker Tilly.
- The Cynosure Group (family-office-backed) and an employee ownership group are the capital structure backers.
- The decision followed a year-long collaborative process between wealth leadership, Moss Adams executives, and Baker Tilly leadership.
- Threadline keeps its tax-led service model focused on HNW families and business owners, with a heavy West Coast client base including Silicon Valley.
What Did Baker Tilly Actually Spin Out?
Moss Adams Wealth Advisors was the legacy advisory arm built inside Moss Adams, a Seattle-based regional accounting firm long ranked among the top 15 U.S. CPA firms by revenue. When Moss Adams combined with Chicago-based Baker Tilly in June 2025 to create one of the largest non-Big-Four advisory firms in the country, the wealth arm came along by default rather than by strategic intent.
The wealth team specialized in tax-led financial planning for HNW families, business owners, and pre-IPO clients in the Pacific Northwest, the Bay Area, and Southern California. Its core service was integrated tax-investment-estate planning, with the CPA relationship driving advisor introductions. AUM at the time of the merger was roughly $5.2 billion. The figure has grown to $5.8 billion at spinout, implying mid-single-digit organic growth even during a year of corporate transition.
The Cynosure Group, the lead capital provider in the new structure, is a Salt Lake City-based investment firm that holds wealth management platform investments and has been quietly adding RIA capital partnerships since 2023. The firm’s involvement signals that the spinout was not a defensive move but a backed growth bet.
Why Did the Accounting Model Stop Working?
Justin Fisher, in the announcement materials cited by WealthManagement.com, pointed to three concrete frictions that drove the decision:
- Regulatory frameworks diverge. SEC and FINRA registrations require different audit trails, compliance investment, and supervisory structures than AICPA peer review and state CPA licensing. Running both inside a single legal entity multiplies the cost of compliance without creating proportional revenue lift.
- Technology stacks pull in opposite directions. A modern RIA requires deep investment in performance reporting, billing, portfolio rebalancing, financial planning software (eMoney, RightCapital), and alternative investment platforms. An accounting firm invests in tax engines, audit software, and practice management tools. The capital allocation choices are fundamentally different.
- Capital investment cadence. Accounting firms reinvest at predictable annual rates from partner profit pools. RIAs increasingly need access to growth capital for acquisitions, recruitment packages for breakaway advisors, and equity stakes for retention. PE and family office capital is structured for the second pattern and rarely for the first.
Eric Miles, who led Moss Adams before the Baker Tilly merger and now leads the combined accounting platform, framed the spinout as a recognition that the two disciplines benefit from operating independently rather than under shared governance.
Threadline’s Cynosure-Backed Growth Math
The Cynosure Group’s involvement places Threadline alongside a small set of RIA platforms backed by family-office capital rather than traditional PE buyouts. The structural distinction matters because the exit math differs:
- Traditional PE-backed RIA platforms (Mariner, Hightower, Wealth Enhancement, Focus Financial successors) operate on 5-7 year hold periods with leverage and target exit at 3-5x EBITDA multiples.
- Family-office-backed platforms like Cynosure typically operate with longer holds, lower leverage, and a thesis of compounding ownership rather than multiple expansion.
For Threadline, that means the capital partner is not pushing a near-term sale. The firm can use its growth capital for selective tuck-in acquisitions, technology investment, and recruiting without near-term pressure to hit a private-market valuation milestone.
The site has covered the private equity dominance of RIA M&A, with 90% of 2026 deals having a PE component. The Cynosure structure offers an alternative thesis that is gaining adherents among advisors who want growth capital without the PE timeline.
How Big Is the Accounting-Firm-Wealth Reversal?
The broader trend is that accounting-firm-owned wealth platforms are reorganizing in 2026. The post-Sarbanes-Oxley wave that consolidated wealth advisors inside CPA firms is unwinding.
EisnerAmper sold a majority stake to TowerBrook in 2021 and the wealth arm has since rebranded multiple times. Eisner Advisory Group operates as a more autonomous unit. Several mid-tier accounting firms have been quietly selling or spinning out wealth divisions to PE-backed RIAs to clean up capital structure ahead of accounting-firm consolidation.
Threadline’s separation is the largest, cleanest example of the trend in 2026 and gives other accounting firms a template. The decision was framed not as a divorce but as a recognition that the integrated model creates more friction than synergy at scale. That phrasing matters because it removes the stigma associated with prior CPA-RIA separations, which were often driven by partner disputes or regulatory pressure rather than strategic intent.
How Does This Fit Into Q1 2026 RIA M&A?
Q1 2026 set a record for RIA M&A activity. The site covered both the DeVoe & Co. Q1 2026 tracker with 93 deals and the broader Echelon Partners count of 142 deals totaling $1.67 trillion in AUM for the quarter.
Spinouts like Threadline do not always count in traditional M&A trackers because no acquisition takes place. Threadline is a corporate separation with capital partnership rather than a sale. But for the practitioner counting AUM in motion, the $5.8 billion movement is comparable in scale to a top-15 RIA M&A deal of the quarter.
The 2026 trend in RIA capital flows includes three distinct vectors:
- PE-backed roll-ups acquiring sub-$1B firms to build scale platforms (Hightower, Wealth Enhancement, Beacon Pointe, Mariner)
- Wirehouse breakaways landing on independent platforms, as the site covered in the April breakaway wave
- Accounting-firm spinouts like Threadline, where mid-to-large wealth divisions exit their CPA parents to reorganize as independent RIAs
The third bucket has historically been the smallest, but Threadline’s size and visibility may accelerate the pace through 2026 and 2027.
What Threadline’s Tax-Led Model Tells Us About 2026 HNW Demand
Threadline’s positioning matters as much as its size. The firm is keeping its tax-led service model, where tax planning sits at the center of the advisor relationship and investment management follows. For HNW families with concentrated stock positions, business owners facing exit planning, and Silicon Valley clients with equity compensation, that structure has been a durable competitive moat.
The 2026 environment has pushed tax-led planning to the forefront for three reasons:
- OBBBA permanence. The 2017 tax cuts made permanent under the One Big Beautiful Bill Act in late 2025 created structural certainty advisors can plan around for the first time in eight years.
- SECURE 2.0 contribution and Roth complexity. Catch-up, super catch-up, and Roth mandate rules have made retirement income planning materially more technical.
- Higher estate exemption. The $15 million estate tax exemption for 2026 created planning urgency for HNW clients who can use one-time gifting strategies inside the window.
Threadline’s CPA-trained advisor base is positioned to capture the planning fee opportunity in all three buckets without external coordination with tax preparers.
Where Are the Risks?
Operational independence carries its own friction. Three risks deserve advisor attention:
- Client retention through the transition. Some Moss Adams Wealth clients chose the integrated CPA-RIA model deliberately. A subset may revert to standalone CPA service plus a different advisor of their choosing. Industry norms suggest 5-10% client attrition during spinouts of this size.
- Technology and operations cost shock. Threadline now bears its own compliance, technology, and HR cost stack rather than allocating overhead to a larger accounting firm. The economics work at $5.8B AUM but tighten if attrition exceeds expectation.
- Cynosure exit timeline. Even family-office capital eventually seeks a return. Threadline will need a documented growth plan that satisfies Cynosure’s compounding thesis or face restructuring pressure within 7-10 years.
None of these risks is unique to Threadline. They are the standard risks of any RIA spinout and Threadline’s scale, leadership continuity, and capital backing put it in a better starting position than most.
What Buyers Now Pay For: Lessons From Threadline
Threadline’s spinout offers a useful pricing signal for advisors evaluating their own platform decisions. The premium attached to:
- Tax integration is real. CPA-tied wealth practices command higher organic growth multiples than pure investment management RIAs.
- HNW concentration matters. Threadline’s $5.8B across what is likely under 1,500 households implies average accounts in the $3-5M range, which is the demographic with the highest planning fee opportunity.
- Geographic diversification with West Coast tilt is a positive. Silicon Valley client exposure adds tail risk during venture capital downturns but compounds during normal markets.
- Independent governance with capital backing is the structural form most attractive to growth-stage advisor talent. Advisors looking to join a platform with growth capital but without PE timeline pressure now have a clearer model to evaluate.
What to Watch in Q2 and Q3 2026
Three signals will tell allocators and advisors whether Threadline becomes a platform builder or stays a single-firm story:
- First acquisition. A tuck-in acquisition of a sub-$500M tax-led practice in the next 18 months would confirm the platform thesis. Absence of one would suggest Threadline is more focused on organic growth.
- Recruiting wins. Hiring of senior breakaway advisors from wirehouses or other RIAs would confirm Cynosure capital is being deployed for growth.
- Other accounting firm spinouts. If a second mid-tier CPA firm announces a wealth division spinout in Q3 2026, the trend accelerates and could reshape how the top 25 accounting firms structure their wealth divisions.
Questions Advisors Should Ask Their Practice Leadership
- If our firm has a CPA-RIA integration similar to the old Moss Adams model, what is our written assessment of the regulatory, technology, and capital frictions Threadline cited?
- Do we have a documented succession path for wealth-side leadership that is independent from accounting-side governance?
- If our growth capital comes from accounting partner profit pools, is that sufficient to compete with PE-backed and family-office-backed RIA platforms for advisor recruiting in the next 36 months?
Threadline Wealth is not a corporate event most advisors will follow week to week. But the structural decision behind it, separating wealth from accounting at $5.8 billion of scale rather than continuing to integrate, signals where the next chapter of RIA M&A and platform building is heading. The firms that read the Threadline announcement carefully will be the ones positioning their own businesses for 2027.
