Hi, I’m Chris Walton, author of this guide and CEO of Eton Venture Services.
I’ve spent much of my career working as a corporate transactional lawyer at Gunderson Dettmer, becoming an expert in tax law & venture financing. Since starting Eton, I’ve completed thousands of business valuations for companies of all sizes.

Read my full bio here.
Carta is one of the most well-known names in the 409A valuation space, but there are ongoing concerns about whether its reports meet the standards auditors and the IRS expect.
Here are the issues companies most often encounter using Carta’s 409A services:
If you’re hearing these concerns for the first time, or if you’ve already had a less-than-ideal experience with Carta, it’s natural to look for alternatives that provide guaranteed compliance, senior-level judgment, and stronger support.
To help you find the right fit, I’ve rounded up six trusted 409A valuation providers that operate independently and can be trusted to deliver fully compliant reports that protect your company and your employees.
Before choosing a 409A valuation alternative,it helps to know what separates the good from the great Here are the most important qualities to look for:
I’ve helped hundreds of companies through their 409A valuations, so I know how stressful it can be to choose the right firm.
The providers on this list are ones I’d trust, firms that know how to deliver accurate, defensible valuations and treat their clients like partners rather than transactions.
Let’s dive in:
At Eton Venture Services, founders and CFOs turn to us when they need audit-ready 409A valuations done quickly and done right.
Led by former Big 4 consultants, we combine technical rigor with real-world understanding of what investors, boards, and auditors expect. That’s how we deliver valuations that hold up under scrutiny and stay fully compliant from the start.
As a boutique firm, you work directly with senior valuation professionals who stay hands-on from start to finish. That means fast responses, real collaboration, and none of the layers or template-driven shortcuts you’d find elsewhere.
We also believe accuracy shouldn’t come at a premium. Our pricing is transparent, affordable, and built to support companies through every stage of growth, without tying valuations to subscription tiers or software plans.
With more than 10,000 valuations completed and a perfect audit record, we’ve built our reputation on reliability, responsiveness, and results.
Here are three reasons why people choose Eton:

When option grants or funding rounds are on the line, timing matters. Our streamlined process delivers fully IRS-compliant, audit-defensible 409A reports in 10 days or less. For urgent needs, an expedited one-business-day turnaround is available.
That speed doesn’t mean cutting corners. We keep quality consistent across every report, making sure each valuation is accurate, defensible, and able to withstand any level of review.

2. Eton brings human, senior-level expertise to every valuation
Eton’s process is human-first, free from automation or outsourcing. Each valuation is prepared by senior, Big 4-trained professionals who understand the nuances that shape 409A value, from complex cap tables to financing rounds and equity terms.
This hands-on, expert-led approach ensures your valuation captures the real economics of your business rather than relying on a generic model or automated tools like Carta, giving you a 409A valuation report that reflects your company’s structure and risk profile, holds up under audit, and prevents compliance and diligence issues down the road.

3. Eton is trusted by boards, auditors, and diligence teams
Every valuation we deliver is built to meet the standards of the people who actually review it, your board, your auditors, and diligence teams.
We make sure each valuation meets formal 409A requirements, including:
These are foundational elements companies sometimes discover are missing in Carta’s reports.
Everything is structured so reviewers can easily follow how we arrived at fair market value and confirm safe harbor compliance.
And when diligence teams push deeper, Eton acts as your technical shield. We handle the back-and-forth with auditors and acquirers, speaking their language and resolving red flags behind the scenes so valuation questions never become your problem.
Here’s what one of our clients had to say about working with Eton:

Kruze is one of the first alternative firms I’d recommend for VC-backed startups.
They provide standalone 409A valuations, and they also provide accounting, tax, and CFO support, which makes them a strong option if you want all those services handled under one roof.
The valuations are audit-ready, and their team includes former Big 4 valuation partners and investment bankers who’ve worked with hundreds of companies.
Kruze’s reports follow AICPA and USPAP guidelines, and their valuation partners hold top credentials like ASA and ABV. They understand company cap tables, venture rounds, and the level of precision required to meet IRS safe harbor standards.
If you’re looking for a firm with deep financial infrastructure and a solid 409A offering for VC-backed companies, Kruze is a good choice. But if what you need is a valuation-first partner, then that’s exactly what we’ve built here at Eton.
Teknos Associates stands out for one key reason: They deliver “dual-use” valuation reports that meet both IRC 409A (tax compliance) and ASC 718 (GAAP accounting) standards in a single analysis.
For companies preparing for audits, securing board approvals, or meeting investor and transaction timelines, that’s a huge advantage. It eliminates duplicate work and ensures every valuation stands up to scrutiny on both the tax and financial reporting sides.
Their reports are built to withstand Big Four and SEC review and have been relied on in major events like IPO filings and acquisitions.
The firm has prepared thousands of these valuations for private companies across industries such as technology, artificial intelligence, life sciences, and biotech – sectors where the valuation story is often complex and highly scrutinized.
Teknos notes that they can “rapidly” prepare a dual-use report at a “reasonable fee,” though they don’t publish specific pricing or timelines, so you’ll need to contact them directly for details.
Aranca is another strong option for companies looking for 409A valuations that hold up under serious scrutiny. They’ve been doing this since 2005, and their reports have withstood audits from the Big Four and even the SEC, a track record that says a lot.
One standout: they guarantee free lifetime audit support at no extra cost, which means if questions arise later, they’ll engage without billing you again.
Their consultants commit a minimum of 40 hours per valuation, and clients can engage directly with senior team members throughout the process.
Turnaround typically takes 7 to 10 business days, and pricing starts at $1,299. This makes it one of the more affordable options for companies that still want quality and compliance.
A potential drawback to keep in mind: Aranca is based in India, which means time zone differences and off-hours overlap can slow real-time coordination or push conversations into inconvenient times. For some clients, that extra “lag” may feel like a friction point in an already demanding process.
Stout runs a dedicated 409A practice known for its analytical depth. Their team applies advanced valuation methods to capture the full picture of complex ownership structures and multi-scenario exits, where quick, formula-driven approaches often fall short.
They’re also unusually transparent about their approach, publishing clear guidance on how they build valuations and interpret deal data, convertible instruments, and vesting terms. This openness gives companies better visibility into the process and more confidence when their valuation is reviewed.
However, Stout operates on a larger scale than most boutique firms, which means their process may feel more structured and less personal. If you prefer a more tailored, boutique engagement with direct involvement from senior professionals, Eton is the better choice.
A practical note: Stout doesn’t publish list pricing or a standard turnaround for 409A. If speed or budget targets matter, you’ll need to contact them directly for scope, fee, and timing.
Redwood is a valuation-first firm that explicitly warns against relying on “automated” 409A providers, which can leave companies vulnerable under audit – a principle we firmly stand behind at Eton, too.
The firm turns that stance into practice: they build 409A valuations around your company’s specific risk profile and cap-table economics, applying professional judgment rather than one-size-fits-all templates, so the result reflects your actual structure and stage.
Worth noting, Redwood includes total equity or enterprise value in their reports so companies see the full picture of how their valuation was determined, not just the price per share. That added context also helps boards and auditors make quicker, more informed approvals.
They promise draft delivery in 3-4 weeks, with complex cases stretching to 6 weeks. If you don’t mind asking them about the price, Redwood is a name you can trust.
409A valuations typically cost $2,500–$4,000.
Where you fall in that range depends on the complexity of your company’s structure and the turnaround time you need.
Some platforms bundle valuations into subscription plans (like Carta, Pulley, or Eqvista), while independent valuation firms typically quote per engagement.
At Eton Venture Services, we quote per engagement, and our pricing remains affordable for early- and late-stage startups alike, all while ensuring your report is safe-harbor compliant, audit-defensible, and delivered quickly without unnecessary add-ons.

At Eton Venture Services, the full 409A process typically takes up to 10 business days once we receive your documents.
For early-stage companies with straightforward structures, reports are often delivered even faster.
When timing is tight, such as before a board meeting, option grant, or funding close, we also offer an expedited one-day turnaround.
That speed never comes at the expense of quality. Every valuation is prepared and reviewed by senior professionals to ensure it’s accurate, defensible, and fully IRS-compliant.
The IRS safe harbor rules require a new 409A at least once every 12 months or sooner if a material event occurs that could change your company’s value.
Common material events include:
If any of these occur, your previous valuation may no longer reflect fair market value, meaning it’s time to update.
At Eton Venture Services, we help clients assess whether an event qualifies as material and provide updated, audit-defensible valuations quickly so you stay compliant and ready to issue new grants. Contact us for a free consultation.
Platforms can be convenient, especially if you already manage your cap table there. But convenience isn’t the same as reliability, and with 409A valuations, reliability isn’t optional.
A 409A has to be defensible, accurate, and safe-harbor compliant. Subscription-based platforms often rely more on automation, which can limit the amount of senior, professional judgment applied to your valuation.
There’s also an inherent conflict of interest: many platforms treat valuations as a low-cost feature meant to keep you subscribed, not as a high-stakes appraisal that requires independent judgment.
A software add-on can’t push back, ask hard questions, or tell you when your inputs don’t line up with reality. A standalone provider exists to do exactly that, and has no incentive to soften the truth.
For any company that wants full confidence that its valuation will hold up under IRS or auditor review, a standalone provider, like Eton, is the more dependable choice.
If you want a clearer picture of how the two options differ, here’s a quick comparison:
