We scaled TrueCoach to 20,000 paying customers across 100 countries. We exited to private equity in 2020. And we never hired a single salesperson.
No BDRs. No account executives. No sales manager. No CRM full of leads being worked through a pipeline.
Every customer who ever paid us found TrueCoach through digital marketing, signed up for a free trial, and converted on their own. The entire revenue engine was self-serve.
This wasn't an accident or a constraint we were working around. It was a deliberate choice that shaped our unit economics, our product, and ultimately our outcome.
Here's why we made that choice, how we made it work, and how to know if it's right for your SaaS.
The decision to skip sales wasn't philosophical. It was mathematical. Understanding unit economics and financial fluency made this decision obvious.
Our average contract value was around $50/month. Call it $600/year. At that price point, the math on sales doesn't work.
A decent account executive costs $80-120K base plus commission. Let's say $150K fully loaded. To justify that cost, they need to close enough revenue to cover their salary plus generate profit.
At $600 ACV, that AE needs to close 250+ customers per year just to break even. That's more than one new customer per business day, every day, with no ramp time.
It doesn't pencil out.
But here's what did work: a $15 cost per free trial, a 20% conversion rate to paid, and an LTV of $1,500.
Our self-serve unit economics:
At those numbers, we didn't need salespeople to convince anyone. We needed a product that sold itself and a funnel that converted efficiently.
Every dollar we would have spent on sales salaries went into paid acquisition instead. And because digital marketing scales linearly with spend (until you exhaust your audience), we could grow as fast as our unit economics allowed.
Saying "we didn't have sales" makes it sound easy. It wasn't. Skipping sales meant building everything else to compensate.
With no salesperson to demo the product, explain the value, or handle objections, the product had to do all of that on its own.
TrueCoach needed to deliver obvious value within minutes of signup. If a coach couldn't figure out how to create a workout and send it to a client within their first session, we'd lose them.
This forced us to obsess over onboarding. Every friction point in the first-time user experience was a conversion killer. We tracked where users dropped off and systematically eliminated obstacles.
The product wasn't just the features. It was the entire experience of going from "I just signed up" to "this is clearly worth paying for."
Our 14-day free trial was the entire sales process. No calls. No demos. No check-ins from a customer success rep.
The trial period had to:
We built automated email sequences that guided users through each stage. Not generic "how's your trial going?" emails. Specific, behavioral emails triggered by what users did or didn't do in the product.
If a coach signed up but hadn't created their first workout after 48 hours, they got a specific email addressing that. If they'd created workouts but hadn't invited a client, different email. If they'd invited clients but hadn't logged in for three days, another trigger.
The email sequences were our sales team. They just happened to be automated and cost essentially nothing to run.
With no salesperson to walk through pricing options or negotiate custom deals, our pricing had to be dead simple.
We didn't do annual contracts with discounts that required a call to set up. We didn't have enterprise tiers with "contact us for pricing." We didn't negotiate.
One price. Pay monthly. Cancel anytime.
This left money on the table from customers who would have paid more for annual commitments or enterprise features. But it also meant every customer could convert without friction. No back-and-forth. No procurement process. No waiting for a sales call.
The simplicity converted.
The same customers who would normally talk to sales had questions. Without salespeople, those questions came to support.
We couldn't afford to scale support linearly with customers. So we built:
Casey and I personally handled support in the early days. Every ticket taught us something about where the product was confusing or where documentation was lacking. We treated support volume as a product feedback mechanism, not just a cost center.
Over time, the product got clearer and support load per customer dropped. That's the compounding benefit of building for self-serve: every improvement reduces future support burden.
Our entire "sales process" was a funnel:
Top of Funnel: Paid Acquisition Facebook and Google ads drove traffic to landing pages. The ads targeted fitness coaches, gym owners, and personal trainers. The landing pages spoke directly to their pain points: wasting time on spreadsheets, losing track of clients, struggling to scale their coaching business.
Middle of Funnel: Free Trial Signup The landing pages had one job: get the visitor to start a free trial. Not "learn more." Not "request a demo." Start a free trial.
We tested hundreds of landing page variations. Headlines. Hero images. Social proof. Form length. Button copy. The goal was always the same: minimize friction between "interested" and "trying."
Bottom of Funnel: Trial-to-Paid Conversion Once someone started a trial, the automated sequences took over. Onboarding emails. In-app prompts. Usage-triggered messages. Everything designed to get them to the "aha moment" as fast as possible.
For TrueCoach, the aha moment was when a coach sent their first workout to a client and saw how much easier it was than their old process. Once they felt that, they were hooked.
Conversion Trigger: Payment At the end of the trial, we asked for a credit card. Simple. No call required. No negotiation. Just a decision: is this worth $50/month?
If we'd done our job in the trial, the answer was obvious.
Self-serve isn't universally better than sales. It's better under specific conditions.
ACV is under $5K/year Below this threshold, sales economics are brutal. The cost of a salesperson exceeds the value of the contracts they can close. Self-serve lets you acquire customers profitably at price points that would kill a sales-led model.
The product can demonstrate value quickly If users can experience the core value proposition within a free trial, you don't need a salesperson to explain it. If the value only becomes apparent after months of implementation, you probably need sales.
The buyer can make the decision alone TrueCoach customers were individual coaches or small gym owners. They could try the product, see the value, and enter a credit card without getting approval from anyone. Enterprise products with procurement processes and multiple stakeholders usually need sales to navigate that complexity.
The market is large and distributed We had a million+ potential customers worldwide. No sales team could reach them all. Digital marketing could. Self-serve scales to markets that sales can't efficiently cover.
ACV is $20K+ per year At higher contract values, the math flips. A salesperson who closes 30 deals at $50K each generates $1.5M in revenue. That justifies significant sales investment.
The product requires customization or implementation Complex products that need configuration, integration, or training benefit from human guidance. Trying to do this self-serve creates frustrated customers and high churn.
The buyer needs consensus When multiple stakeholders have to agree, a salesperson can navigate the politics, address different concerns, and push deals forward. Self-serve funnels don't handle buying committees well.
The market is concentrated If you're selling to 500 potential customers, each worth $100K+, sales is more efficient than marketing. You can name-target accounts rather than hoping they find you through ads.
Beyond the direct cost savings, skipping sales had second-order benefits we didn't fully appreciate until later.
When there's no salesperson to paper over product gaps, the product has to be good. Every rough edge costs you conversions.
This created healthy pressure to fix things. If users were dropping off at a particular point in onboarding, we couldn't just tell sales to explain it better. We had to actually fix it.
Salespeople, even good ones, sometimes close customers who aren't a great fit. They're incented to close deals, and a customer who churns in six months still counts toward this quarter's quota.
Self-serve naturally filters for fit. Customers who converted were customers who genuinely found value in the product during the trial. They understood what they were buying. They weren't oversold.
This showed up in our retention. Our churn was around 3% monthly, which is solid for a $50/month product. I think the self-serve model contributed to that. Every customer chose us with clear eyes.
Sales-led growth requires hiring ahead of revenue. You need to add salespeople before you can grow, which means runway risk and management complexity.
Self-serve growth lets you scale spend without scaling headcount. When we wanted to grow faster, we increased ad budgets. When we wanted to slow down, we pulled back. No hiring, no firing, no ramp time.
This made us more capital-efficient and gave us more control over our trajectory.
With 100% self-serve acquisition, we could trace every customer back to the campaigns that acquired them. We knew exactly which ads, landing pages, and email sequences drove revenue.
Try getting that clarity in a sales-led model. Was it the SDR's outreach? The AE's demo? The marketing campaign that sourced the lead? The content they read six months ago? Attribution in sales-led models is a mess.
Our clean attribution let us optimize with confidence. We knew what was working and could double down. Proper tracking made this precision possible—something most companies struggle to achieve even with sales teams.
I'm not going to pretend self-serve is all upside. We made tradeoffs.
Some fitness businesses would have paid significantly more for TrueCoach. Multi-location gym chains. Franchise operations. Corporate wellness programs.
We didn't pursue them. Our product wasn't built for enterprise. Our pricing wasn't set up for large contracts. We didn't have salespeople to navigate those deals.
We left money on the table. Whether that was the right choice depends on your goals. We wanted efficient growth and a clean business model. We got that. But we probably capped our ceiling in exchange.
Salespeople learn things about customers that self-serve funnels don't capture. They hear objections, concerns, and competitive context in real-time.
We had to work harder to get that qualitative insight. User research. Customer interviews. Support ticket analysis. It was doable, but less natural than having salespeople who talked to prospects all day.
When a salesperson demos your product, they control the narrative. They can emphasize strengths, preempt objections, and frame the product in the best light.
Self-serve means the customer controls their own experience. If they use the product wrong, get confused, or miss the key feature, there's no one there to course-correct.
We tried to compensate with onboarding design, but we couldn't fully replicate what a skilled salesperson does in a live conversation.
If you're building a SaaS company and trying to decide between self-serve and sales-led, here's how I'd think about it:
Start with ACV. Below $5K/year, default to self-serve. Between $5-20K, you're in the hybrid zone. Above $20K, default to sales.
Look at your trial conversion. If you can get 10%+ of free trials to convert without human touch, self-serve can work. If you're below 5%, the product probably can't sell itself yet.
Consider your buyer. Individual practitioners? Self-serve. Small teams with a single decision-maker? Self-serve. Enterprise with procurement? Sales.
Assess your market size. Large, distributed markets favor self-serve. Concentrated markets with high-value accounts favor sales.
Be honest about your product. Does it deliver obvious value quickly? Or does it require explanation, configuration, and handholding? Self-serve demands products that are immediately useful.
And remember: you can start self-serve and add sales later. Many SaaS companies build a self-serve foundation, then layer on sales for upmarket expansion. The reverse is much harder.
TrueCoach scaled to 20,000 customers and a successful exit without ever hiring a salesperson. The entire business was built on self-serve acquisition: paid ads driving free trials, automated onboarding converting trials to paid, and a product that demonstrated value without human explanation.
This wasn't the only way to build TrueCoach. It was the way that matched our price point, our market, and our strengths.
If you're building a SaaS with sub-$5K ACV, selling to individual buyers or small teams, in a large distributed market, self-serve is probably your path. The unit economics work. The model scales. And you avoid the complexity and cost of building a sales org.
You just have to build everything else to compensate: a product that sells itself, onboarding that converts without human touch, and a funnel that operates like a machine.
We did it. You can too.
The same principles that powered TrueCoach's self-serve success—efficient acquisition, automated conversion, clear attribution—are what we build for clients at GrowthMarketer.
