The Demand Engine Never Existed — Jason Tatum (Mixmax)

Executive Summary

The one-paragraph brief, extended

Why this conversation matters — and who should spend the hour.

Jason Tatum joined Mixmax in November 2025 to run product. By May he was asked to run the company. He said yes for two reasons: a team his predecessor had hired to an annoyingly tight standard, and a product people genuinely love — "Most people have never heard of it. But the people that have, so many of them swear by it." Those fans had never been propped up by a go-to-market engine that could amplify them. He first assumed the demand engine had broken somewhere along the growth curve. What the team uncovered was that it had never existed.

The two cases need different fixes: a broken engine gets diagnosed and repaired, while one that was never built has to be constructed from zero as the business runs. Mixmax had bootstrapped and run lean, and the product was good enough that fish were just jumping in the boat: prosumers and founders first, then mid-market and enterprise teams asking for it. "And you've done no marketing. It's just happening." The company pivoted hard into direct sales, but the discipline of continuously generating demand never matured underneath it. On his first day Jason asked how the Google ads performed and what CAC was. There were none. Post-COVID contraction and failed product bets compounded it: "You're still not invested in your SEO or AEO now. And that can be fatal if it goes on for too long."

The second problem is language. Twelve years in, with product-market fit, Mixmax still could not describe itself in its customers' words — two motions — self-serve and direct sales, teams of one and teams of a hundred — made a single identity hard to hold. His correction, from 37signals co-founder Jason Fried, is to use customers' words: "If you Google Mixmax, it's gonna say we're a sales engagement platform. Guess what? Nobody that comes to our website is Googling sales engagement platform." Customers describe the follow-up grind — many don't consider themselves salespeople — and nobody thinks about your features; they're the center of the story.

Then the non-obvious find. The sales team was trained only on direct mid-market and enterprise, outbound wasn't working, and no inbound engine fed it. Meanwhile an astounding share of visitors arrived by typing "Mixmax" — the highest-intent traffic there is — and could reach a salesperson only if they were worth a certain amount and wanted an annual deal. "And you'd think that our sales team was just so busy over here doing this thing, but their calendars were empty." The org was still building routing rules, tooling and channel spreadsheets on top of that emptiness. Anthony Enrico names the same failure in RevOps; Jason's version is blunter — you're optimizing an empty calendar, and there's nothing to optimize.

The strategic answer is restraint. He invokes Crossing the Chasm: get your foot on the beach, hold one spot, then decide deeper or wider. He admits an honest fear of alienating bigger customers — Mixmax keeps a best-in-class Salesforce integration and SOC 2 — but says winning long term takes a much narrower market and leaning in where the company already wins without trying: referrals, agency partnerships, a free trial for every signup. The personal half sits underneath. Nine years at CallRail with no skipped levels; a grandmother who went from Delta's secretary pool into Delta management; "no one arrives mature," so he hired finance help and freed the English-major brain for the message; the CEO job is external, and it's not how, it's who. When the Prague list looked impossible, two words from Anne Lamott: bird by bird.

Key Takeaways

15 things worth stealing

The load-bearing ideas, each with the business implication and who should care.

A demand engine that broke and one that never existed are different problems

Jason came in assuming Mixmax's demand engine had broken somewhere along the growth curve. The archaeology said otherwise: it was never built. The infrastructure to scale with virality — and to hold the company up through ebbs and flows in the market and the competitive landscape — was never put in place.

Why it matters: Diagnosing which one you have changes the whole plan. Repair work assumes something once functioned; a never-built engine has to be stood up from zero while the business is already running at scale.

Virality is not an acquisition strategy — it just hides the absence of one

The early team was lean and bootstrapped, and the product was good enough that fish were just jumping in the boat. With that rate of inbound, and with sales teams hiring aggressively, leaning on virality and word of mouth simply seemed efficient — so nobody ever stood up an acquisition motion underneath it.

Why it matters: Anthony's closing warning to operators: a good season is exactly when to build discipline. Stack the go-to-market motions while virality is carrying you, because it will slow down.

Day one: "How do our Google ads perform?" — there were no Google ads

Jason expected paid search and CAC numbers because the product is so self-evidently PLG-native. The answer was that Mixmax didn't run Google ads. Coming from CallRail, where a world-class marketing operation had been built on top of an already great product, he saw none of the patterns he had absorbed by osmosis.

Why it matters: He is explicit that this is not an indictment of anyone at Mixmax — macro headwinds and product bets that didn't land contributed. But the untreated version compounds: still no paid, still no SEO or AEO investment, and "that can be fatal if it goes on for too long."

A 12-year-old company with product-market fit and no language for it

Customers call Mixmax essential and say it makes their lives easier — and then struggle to explain what it actually does. Jason traces the identity problem to running two motions for years, self-serve and direct sales, the one-person team and the hundred-person team, and trying to cater to both.

Why it matters: Product-market fit does not guarantee message-market fit. Mixmax is rebuilding the message from scratch by going back through customers and leads to answer what the message is and who it is really for.

Describe yourself the way your customers describe you

The philosophy comes from 37signals co-founder Jason Fried. Applied to Mixmax, it kills the category label: Google says Mixmax is a sales engagement platform, but nobody searching for it types that, and no customer or lead uses it. What customers describe is the follow-up grind — keeping relationships alive, not dropping the ball, getting to the next meeting.

Why it matters: The customer sentence does not fit as neatly on a slide as the category name, but it is the reality, it is valuable, and people pay for it. Anthony notes he has made the same mistake at LeanScale: being a connoisseur of what you do pushes you toward language that captures all your capabilities rather than language customers resonate with.

The customer is the center of the story, not your product

Jason's framing is that customers don't think about your business in any way except whether it solves the problem it is supposed to solve — and ideally they aren't thinking about you at all, because it just works. They are not thinking about sequences unless they happen to be an account executive.

Why it matters: That applies beyond the homepage. The onboarding has to resonate with the problem someone showed up to solve, not the problem you hope they'll want solved one day, and pricing has to coalesce with the value being delivered.

The non-obvious find: the highest-intent users couldn't talk to anyone

Mixmax's sales team was trained only on direct — mid-market and enterprise — with no inbound engine feeding that pipeline and outbound not working. Meanwhile an astounding share of site visitors arrived by literally typing "Mixmax," already sold by someone else, and could only reach a salesperson if they were worth a certain amount of money and wanted an annual contract.

Why it matters: Jason's fix is to point the sales team at the people who are already there: "These are the people that showed up to your birthday party, talk to them." Revenue and by far the greatest number of actual users were coming through with high intent and hitting a wall.

The empty-calendar test: you cannot optimize a pipeline you don't have

Going from zero-to-one into scaling pushed Mixmax toward process, heavy tooling, routing complexity and a complicated channel spreadsheet — all built on top of empty calendars. Jason's image for it is the cliché about fishing with a spear rather than a net: good advice, except at some point you have to throw the spear, and it felt like they were always sharpening it.

Why it matters: Anthony calls this the most common version of the mistake in RevOps: getting excited about building a capability when the volume to justify it isn't there and something else should be solved first. Optimization is not possible when there is nothing to optimize.

Get your foot on the beach before you decide where to go

Jason understands why growth companies chase upmarket — value is attached to growth, and as the base gets bigger the percentages get harder, so you eventually have to explore new territory. But drawing on Crossing the Chasm, job number one is finding the port in the storm and establishing yourself firmly in one spot. Only once you're out of the water do you get to choose deeper or wider.

Why it matters: His warning about companies that skip that step is unsparing: "when you look under the hood of a lot of these companies, it's a mess." Going upmarket is a real option, but not before you've proven you can replicate and maximize where you're already strong.

Deliberately not chasing upmarket — while keeping enterprise table stakes

Jason admits an honest fear of alienating or turning away bigger customers, and Mixmax keeps what mid-market and enterprise need: a best-in-class Salesforce integration, which he calls a big differentiator, and SOC 2 compliance. What he wants is a product that solves the problem so well it works regardless of customer size.

Why it matters: To win long term, the company has to focus in on a much narrower market — smaller teams and teams just starting out — rather than bolting on enterprise the way most companies do.

FoundersRevenue ExecutivesSales Leaders

Lean in where you're already winning and not even trying

Jason's stated philosophy is to double down where the company wins without effort. If a co-founder takes Mixmax everywhere he goes and tells people he loves it, the question becomes how to make it easier for him to do that — which turns into a referral program that incentivizes behaviour that already happens naturally, and agency partnerships that share success if Mixmax becomes part of the toolkit they bring to every client.

Why it matters: Paired with giving every signup a real free trial and acting like you care about their success whether they're one person or a hundred, this converts existing evangelism into an acquisition channel instead of leaving it as luck.

"No one arrives mature" — hire the function you're worst at first

There was no real finance function when Jason came in. His response was immediate: he is an English major and needed finance help, so he got it. That freed his brain to sit in Slack threads with his two-person marketing team working out what message to test next.

Why it matters: Buying back attention is the point. Without it, he says, you're swimming upstream — less fun and unlikely to succeed. Everyone is in the process of maturing, so the question is which things you should stop doing because someone else is better at them.

The CEO job is external, and it's not how, it's who

Three months in, the biggest surprise was how much more of the job is external than internal, and how organically that happens — people introduce him to people, and each conversation might leave one idea worth carrying forward. The other reframe, from an advisor, is that a big part of the job is figuring out the who, not the how.

Why it matters: Once the who is established in an area, he stops worrying about it and moves his attention elsewhere, because he knows someone is worrying about the right things. His highest-leverage use of time is being out talking to customers and potential customers so people hear there's a product that solves a problem and a human behind it.

No skipping levels: nine years, every rung, and a grandmother's grit

At CallRail Jason had nearly the same manager for nine years and went from product owner to VP of Product with no skipped levels and no magic doors — including a lead PM rung invented before he could reach director, which he resented at the time. He also credits his grandmother, who dropped out of high school at 16, joined Delta's secretary pool out of necessity and retired in Delta management as the family's breadwinner.

Why it matters: He is now certain that a free pass to executive land would have left him unready and drowning. Anthony's addition: things handed to you may look like blessings but are stunting your growth in disguise.

Bird by bird: how a small team sequences an impossible list

At the team's Prague summit in late June — convened on a half-baked agenda because Jason's instinct was simply to get people in a room — the plan that came out looked like far too much work for a small, lean team. His answer came from Anne Lamott's book on writing, where a boy paralysed by a report on birds is told by his father that he'll get it done bird by bird.

Why it matters: So the order is explicit: get the homepage right, get pricing and packaging right, and the referral program and agency partnerships come after. The video game has levels for a reason — one thing at a time.
