At a glanceQuick answers
What did Retell AI announce?
That it passed $100 million in revenue run rate with $4.6 million raised. Its chief executive Bing Wu said so on X and on the company blog on November 12, 2026.
How fast did it grow?
Wu’s X post says the run rate went from $10M to $100M in 17 months. By our arithmetic that is about 14.5% a month, compounded.
Is Retell profitable?
Wu’s X post says so in one word. It gives no profit figure, and the blog post does not use the word.
Has anyone confirmed the figures?
Not that we found. They are Retell’s own, the company is private, and neither text mentions an audit.

Retell AI says it has passed $100 million in revenue run rate, with $4.6 million raised. Its co-founder and chief executive, Bing Wu, said so on X and in a post on the company’s blog on November 12, 2026. Retell builds AI voice agents that answer and place phone calls for businesses.

This page is read from those two texts. They do not say the same things, and neither says how the run rate was worked out. The figures are Retell’s own, and we have not verified any of them.

  1. A telephone handset beside three rising bars.
    Retell AI’s chief executive Bing Wu said on November 12, 2026 that the voice agent company passed $100M in revenue run rate, with $4.6M raised.
  2. A staircase with an arrow climbing it.
    His X post says the run rate went from $10M to $100M in 17 months and that the company is profitable. By our arithmetic that is about 14.5% growth a month.
  3. A headset surrounded by speech bubbles.
    Retell’s blog post adds 4,000+ customers and 100 million-plus calls a month. It does not repeat the 17 months or the word profitable.
  4. A calendar with a magnifying glass over one day.
    A run rate is a recent period multiplied out to a year. Neither text says which period was used, and neither gives revenue, a margin or a profit figure.
  5. A calculator with a coin beside it.
    Our arithmetic from Retell’s figures: about $8.3M a month, at most about $25,000 a customer a year, and at most about 8 cents a call on average.

§ 01What Retell said

  • The X post. Wu posted at 17:02 UTC on November 12: “Retell just crossed $100M in revenue run rate.” The post had about 640,000 views when we read it at 02:26 UTC.
  • Growth and profit. The same post says “$10M to $100M in 17 months.” It then adds one word, profitable, and the amount raised.
  • The blog post. Retell’s post says the company “just reached $100 million in annualized run rate, with $4.6 million raised.”
  • Customers and calls. The blog post says Retell got there “in under three years, powered by 4,000+ customers running 100 million-plus calls a month on Retell.”
  • An investor. Jack Altman, whose X profile says he is a general partner at Benchmark, wrote at 17:32 UTC that Retell was his first investment as a full-time investor.

Run rate now: 100 million dollars. A note says a run rate is a yearly pace, not a year of revenue. Source line: Retell AI, November 12 2026.

§ 02What a run rate is, and what is missing

  • A pace, not a year. A run rate takes revenue from a recent period, often one month, and multiplies it out to twelve. It says how fast money is coming in now. It is not what a company earned over the past year.
  • The period. Neither text says which period Retell multiplied.
  • Revenue. Neither text gives revenue for any month or year.
  • Profit. The X post says profitable. It gives no profit figure and no margin, and the blog post does not use the word.
  • Checks. Retell is a private company, and neither text mentions an audit.
  • Valuation. Neither text gives one.

§ 03Our arithmetic on Retell’s figures

These are our sums, not Retell’s. Each one rests on Retell’s figures being right.

Question Sum Result
Revenue pace a month $100M divided by 12 About $8.3M
Growth a month, compounded 10 times in 17 months About 14.5%
Run rate against money raised $100M divided by $4.6M About 22 times
Average a customer a year $100M divided by 4,000 At most about $25,000
Average a call $8.3M divided by 100 million calls At most about 8 cents
Table 2What Retell’s figures imply, by our arithmetic
  • Why the last two say at most. Retell says 4,000+ customers and 100 million-plus calls. More customers or more calls would make each average smaller.
  • Averages hide the spread. A few large customers can carry most of the revenue. The announcement gives no breakdown.
  • Against a rate by the minute. A cost calculator on the same blog page starts at $0.11 a minute. At that rate, 8 cents pays for about 45 seconds.
  • What that could mean. The average call may be short, large customers may pay less than that rate, or a call may be counted in a way we do not know. The announcement does not say, and we did not read Retell’s pricing page.

§ 04How Retell says it got there

  • Product first. The blog post says much of its industry relies on large teams of forward-deployed engineers, and that Retell set out to solve deployment in the product itself.
  • Customers run their own agents. Wu’s X post puts it this way: “Our bet: the future of the contact center belongs to the teams who run it.”
  • One customer named. The blog post names Asbury Automotive Group, whose own developers manage Retell agents that answer service calls for its 157 dealerships.
  • Its volume. The post says those agents handled “more than 3.1 million minutes of guest calls” over the past year.
  • In the customer’s words. It quotes Asbury’s Charlie Agrinsoni: “The Retell platform allows our developers to become voice AI developers.”

§ 05What we did not check

  • We did not verify any figure. All of them come from Retell.
  • We read Wu’s X post, two posts that quote it, and the blog post. We did not watch the video in the X post.
  • We did not read Retell’s pricing page or documentation, use its product, or speak to Retell or to Asbury.
  • We did not look for earlier Retell statements on revenue, so we cannot say whether the $10M starting point was published at the time.
  • We did not compare Retell with other voice agent companies.

§ 06Where CellCog sits

CellCog is our product, an AI employee platform. A CellCog AI employee can hold its own phone number and answer calls, so phone work done by AI sits next to what we sell. Retell is a platform for teams that build their own voice agents, and our list of AI receptionists says builder platforms such as Retell are not ranked there. OpenAI makes the image model behind this page’s pictures.

Q2What does revenue run rate mean?

A run rate takes revenue from a recent period, often one month, and multiplies it out to a year. It shows the current pace. It is not the revenue a company earned over the past twelve months.

Q3How much money has Retell AI raised?

Retell’s blog post says 4,000+ customers running 100 million-plus calls a month. The X post gives neither figure.

Q5How much does Retell earn per call?
