Best 409A Valuation Providers for Startups

Best for: Companies already on Carta for cap table

Carta is the market leader in 409A valuations, processing thousands of reports annually for startups ranging from pre-revenue to pre-IPO. Pricing starts around $1,000 for straightforward early-stage valuations but can climb to $3,000-$5,000+ for companies with complex cap tables, multiple share classes, convertible notes, SAFEs, and warrant structures. Standard turnaround is 2-3 weeks, though expedited service is available for an additional fee (typically 50-100% premium) if you need results in under 10 business days. Carta uses a blend of the market approach, income approach, and asset-based approach depending on company stage — pre-revenue companies typically receive a market-based valuation using comparable transactions, while revenue-generating companies get a weighted combination that factors in discounted cash flows. Every Carta 409A comes with an audit-defense guarantee, meaning their valuation team will work directly with your auditors or the IRS if the valuation is challenged. Their reports are widely accepted by Big 4 firms (Deloitte, PwC, EY, KPMG) and regional audit firms alike. Carta is best for companies that already use Carta for cap table management, since the integration eliminates manual data entry and reduces errors. The main downside is price — you are paying a premium for the brand name and ecosystem lock-in.

Best for: Complex valuations (multi-class equity, exotic instruments)

Aranca is the go-to provider when your cap table complexity exceeds what platform-based providers handle efficiently. Pricing starts at $1,500 for standard valuations but typically runs $2,500-$5,000+ for the complex multi-class waterfall models, international subsidiary structures, and exotic derivative instruments that are Aranca's specialty. Turnaround is 2-4 weeks, with rush delivery available in as little as 5-7 business days for a premium. Aranca's methodology is notably rigorous — their team of 200+ valuation professionals applies all three approaches (market, income, and asset) with particular strength in option pricing models (Black-Scholes, Monte Carlo simulation, and binomial lattice models) for allocating enterprise value across multiple share classes. This makes them the preferred choice for companies with participating preferred stock, liquidation preferences, anti-dilution ratchets, and complex waterfall provisions that simpler providers may not model accurately. Their reports carry strong Big 4 acceptance, and Aranca provides litigation support if your valuation is challenged in court — not just IRS audit defense. They also handle international valuations for companies with foreign subsidiaries, transfer pricing implications, or non-US operations. Best for growth-stage and pre-IPO companies with complex capital structures, as well as any company that has had a down round, secondary transactions, or tender offers that complicate fair market value determination. Less ideal for straightforward seed-stage valuations where you would be overpaying for capabilities you do not need.

Best for: Fast turnaround at a mid-range price

Eqvista offers the fastest standard turnaround in the market — most valuations are completed in 1-2 weeks without paying a rush fee. Pricing starts at $990 for early-stage companies, scaling to $1,500-$2,500 for mid-complexity structures, making it a solid mid-range option. Their methodology follows AICPA guidelines using the market approach, income approach, or a combination depending on company stage and available data. For pre-revenue startups, they typically apply the asset-based approach combined with comparable company analysis. For revenue-generating companies, they layer in discounted cash flow analysis with appropriate discount rates for company-specific risk. Every Eqvista 409A includes unlimited revisions — if your auditor pushes back on any assumptions, Eqvista will revise the report at no additional cost until the auditor is satisfied. Their reports include ASC 718 (formerly SFAS 123R) compliance documentation, which is critical for companies that need stock-based compensation expense calculations for their financial statements. Eqvista's reports are accepted by Big 4 and regional audit firms, though they have less brand recognition than Carta or Aranca in the Big 4 community. Eqvista also bundles cap table management with their valuation service, giving you a single platform for equity administration and 409A compliance. Best for companies that need fast turnaround at a reasonable price point — particularly useful when you are closing a funding round and need to issue options quickly, or when you have missed your 12-month renewal window and need to catch up before issuing any new grants.

Best for: Late-stage companies preparing for IPO

Shareworks, backed by Morgan Stanley's institutional infrastructure, is positioned for late-stage private companies and pre-IPO companies that need enterprise-grade compliance and valuation rigor. Pricing is custom and starts around $2,000, but most engagements run $3,000-$5,000+ depending on complexity, global subsidiaries, and the depth of analysis required. Turnaround is 3-4 weeks for standard engagements, reflecting the thoroughness of their process — rush delivery is available but expensive. Shareworks applies all three valuation approaches with particular sophistication in the income approach, using detailed discounted cash flow models with scenario-weighted probabilities for different exit outcomes (IPO, M&A, continuation as private). Their option pricing model implementation for equity allocation is institutional-grade, using Monte Carlo simulation with thousands of iterations to model complex waterfall structures. The Morgan Stanley backing provides unmatched credibility with Big 4 auditors, institutional investors, and regulatory bodies — if your company is heading toward an IPO, having Morgan Stanley's name on your 409A report streamlines the S-1 process. Shareworks also offers global equity plan administration, making it ideal for companies with employees in multiple countries who need coordinated equity compensation compliance. Best for Series C+ companies, pre-IPO companies, and any startup with more than $50M in enterprise value where the stakes of an incorrect valuation are significant. Not cost-effective for early-stage startups with simple structures.
