Second Opinion: They Raised $37M to Remove You From the Only Two Bits of Sales That Work

By /

A startup raised roughly $37 million to sell you a robot that writes cold emails with you fully out of the loop. The bloke who actually built that robot two years ago found out the hard way: the “out of the loop” part is the exact bit that doesn’t work.

Hat-tip to Angus Sewell, who wrote a proper build guide this week on constructing your own AI SDR (sales development rep, the person whose whole job is finding strangers and emailing them) inside Claude. It is genuinely useful and you should read the original here. His stack is four Claude “skills” (small instruction files that tell the model how to do one job), three Airtable tables for memory, and a warmed-up inbox. What I want to add is the part the funding round would rather you didn’t notice.

The autonomous bit is the bit that breaks

The company in question is Artisan, whose AI rep “Ava” logs into your CRM, finds people, researches them, writes the email and sends it, with a human nowhere in the chain. You have probably seen their “Stop Hiring Humans” billboards. That campaign was engineered outrage: it launched in San Francisco in late 2024, drew death threats, and the founder later admitted the anti-human messaging was, in his words, mostly for attention. The same company was hiring dozens of actual humans while the billboards were up (SF Standard). On the money: Artisan raised an $11.5M seed (VentureBeat) and a $25M Series A in April 2025 led by Glade Brook, with HubSpot Ventures in the round (Built In SF). That is your ~$37M.

Here is the tell. Angus built that exact fully-autonomous machine on his own money, spending about $900 a month in credits, and the emails got replies. The problem was what the replies said. People could feel there was nobody behind the message before the phrase “AI slop” even existed. Uncanny valley, in an inbox. The writing was fine. The absence of a human was the product defect.

So the thing a $37M company sells as the headline feature, full autonomy, is precisely the thing the person who built it earliest found to be broken. You are being sold the removal of yourself from the one part of the job that requires you to be there.

The two jobs you cannot hand over

What actually turned Angus’s outbound from confusing to converting was not a cleverer model. It was a human move: find the thing your buyer hates, fix it for free inside software they already pay for, and only mention your product at the end. For him that meant recording a 45-second walkthrough by hand for each prospect. That took a person, it worked, and it scaled a business to around $800k a year before it got acqui-hired.

The second unautomatable job is the reply. Once a stranger writes back, you are talking to a real person, and the fastest way to kill it is to answer three friendly words with an eleven-line brochure. Angus’s rule, quoted verbatim because it is the whole game: “The only goal of any reply is the next reply.” Not the meeting, not the close. One more message.

Notice what these two jobs have in common. They are the exact two functions Artisan’s pitch removes you from. The machine is brilliant at the boring 80% (finding people, enriching them, drafting a first pass, logging who replied) and useless at the 20% that earns the money. Which is a strong argument for building the cheap half yourself and never buying the expensive promise that you can skip the human parts.

Where I push back on the build guide

The framing that everything “takes an afternoon” is the one place Angus undersells the bill. He spent two years and roughly $900 a month learning which half a robot could do. The DIY stack he describes is not a weekend project you set and forget. It is a small standing job: maintaining a scraper, babysitting skills that, as he admits, invent new dropdown values and silently drop prospects out of the pipeline, and warming a fresh sending domain for two to four weeks before you can send anything at volume. He half-concedes this himself, granting that for real volume you buy the execution layer and only build the judgment layer. I would put the line lower than he does. For most solo operators, the honest cost of “free” here is your own time, indefinitely.

The second thing that has changed since he first did this: deliverability got harder. Since February 2024, Google and Yahoo require bulk senders to authenticate with SPF, DKIM and DMARC (three DNS records that prove you are really you) and to keep spam complaints under 0.3%, with under 0.1% the real target, or your mail gets bounced rather than filtered (Yahoo Sender Hub; Mailgun). A tutorial written off 2023 muscle memory can walk you straight into a dead domain. Angus does cover deliverability, and rightly tells you to start it first, but anyone copying an older cold-email playbook should know the filters grade harder now than they used to.

The second opinion, in one line

Build the boring machine if you fancy it. It is cheap and it is a good way to learn. Just do not pay anyone $37M-of-marketing to take you out of the move and the reply, because those are the only two parts that were ever worth money, and they were always going to be yours.

Did you know: Artisan’s outrage campaign reportedly took the company’s brand recognition in San Francisco from about 5% to 70%, which tells you the billboards were the actual product and the AI rep was the merch.
