409A valuation providers for Series B funding
Updated
A Series B round is where most published price lists stop. None of the nine providers we read on 15 August 2026 publishes a Series B price.
Talk to a specialist Nine 409A valuation providers, the four that publish a price, the five that will not, and what each says about turnaround, audit support and who signs the report.
The providers that price by stage quote custom from Series B.
Why a funding round means a new 409A
Treas. Reg. 1.409A-1(b)(5)(iv)(B)(1) says a previously calculated value stops being reasonable at a later date if it fails to reflect information available after the calculation that may materially affect the company's value. A priced Series A or Series B round is that information.
The valuation you had before the round stops protecting option grants made after it. So the new one is usually ordered as the round closes (eCFR, 26 CFR 1.409A-1, read 15 August 2026).

Choosing 409A valuation services for a Series A startup
Series A is the last stage most of the published price lists cover.
- Eqvista publishes $2,590 a year at Series A for unlimited valuations over 12 months.
- Cake Equity sells a valuation at $1,500 as an add-on or inside its $2,750 a year Team plan, and names seed and Series A companies as its fit.
- 409A.io's $99 a month subscription is stated to cover pre-seed through Series A.
- The appraisal firms quote per engagement at every stage.
Which of the 409A valuation services suits a Series A startup comes down to the same things as later. They are how many classes of preferred stock you now have, whether there are SAFEs or notes still to convert, and what your auditor will accept.
What changes at Series B
- Two or more classes of preferred stock, so the value has to be allocated between them rather than read off one price.
- An auditor who reads the report for ASC 718 stock compensation, which several of the firms list alongside 409A work.
- Secondary sales or a tender offer, which can be evidence of value the report has to explain.
- A longer engagement: Redwood states later-stage companies take longer than its 3 to 4 week draft.
