Grow a Subscription Business on a Low Budget

The short answer

To grow a subscription business on a low budget, focus on four techniques: build a community around your product, run webinars that teach before they sell, create a referral program that rewards customers only after a referred customer pays, and integrate with the tools your customers already use. Then add low-cost channels such as content, SEO, partnerships and short video.

Key takeaways

The four shoestring techniques: community marketing, webinars, a customer referral program and embedded integration.
Referrals are my favorite. Pay the reward only after the new customer's first payment, so every reward is covered.
Six referral rewards: one-time cashback, free features or upgrades, a free month, branded swag, ongoing referral fees and associated businesses.
Cheap growth only works if the product keeps its promises. Referrals multiply whatever experience you deliver.
In 2026, several companies reached about $100 million in run-rate revenue with little or no outside funding, using free tiers, shareable outputs and published prices.

A while back I ran a product launch webinar for Dr Libby Weaver, the well-known nutritional biochemist.

Almost 8,000 people turned up.

We came within a hair's breadth of breaking the world record at the time. And that one webinar signed up a lot of clients.

It didn't cost a fortune. We needed a decent microphone, some slides and a good reason for people to show up.

I tell you this because by this point in the book, I know what's on your mind.

Client numbers.

A subscription business isn't much use without subscribers. They're the lifeblood of the whole thing. Without them, you just have something that costs you money to maintain.

So, how do you get clients?

And more importantly... how do you get them on a shoestring budget?

How do you grow a subscription business on a low budget?

Let me start with a cheap plug.

My first book, Feed a Starving Crowd, has 227 strategies for finding hungry customers. If you're serious, grab it and do everything in it that fits your business.

But say you want a quick start. You want techniques you can use today.

Here are my four go-to methods for growing client numbers. Some are 100% free. Others need a small investment, but nothing that breaks the bank.

Community marketing
Webinars
A customer referral program
Embedded integration

After those, I'll give you 50 more low-cost strategies, updated for 2026.

Technique #1: Build a community around your product

Community marketing has been a go-to for SaaS businesses for years.

Take LiveAgent, which sells help desk software. Its former head of marketing, Matej Kukucka, explained how it uses community:

"We run our community on Facebook because it's where most of the SaaS communities are being hosted... Our community is the best way to inform customers about upcoming updates and new features."

Staying in constant touch improved customer satisfaction. And while it doesn't always lead straight to sales, it does two things:

It keeps existing customers happy, so they keep paying.
It gives them a great experience they're likely to talk about with others who need it.

That second point is where the growth comes from. Your community evangelizes for you.

Airbase, which sells spend management software, ran its community on Slack instead. Its event marketing manager, Laura Grandi-Hill, explained:

"Our community, Off the Ledger, runs on Slack. It has been running since November of 2019 and now has a membership of over 1,500... It's a finance and accounting community that helps Airbase grow by giving us a steady pipeline of guest bloggers and webinar speakers."

I love this one. It's a membership within a membership. And Laura said prospects who joined the community were more likely to convert to paying customers than those who didn't.

The tools are free or cheap. It doesn't cost a cent to start a Facebook group, and a Slack or Discord community costs very little.

How I'd run a community in 2026

The principle hasn't changed. The venues have. Go where your customers already spend time:

B2B and professional services: a private LinkedIn group, a Slack community, or a WhatsApp group for your best clients.
Consumers and hobbyists: a Facebook group, Discord, or a members' area with a weekly live session.
Niche experts: be genuinely helpful in the relevant subreddits and forums before you ever mention your product.

Give the community a reason to exist beyond your product: a weekly question, a member spotlight, a monthly "ask me anything" with a guest. If the only posts are your announcements, it's a mailing list with extra steps.

Technique #2: Use webinars to attract new members (and keep existing ones)

Webinars put a face and a voice to your product. People can watch from home without traveling to a seminar, which makes it easy to get big numbers.

And they're cheap. You need a decent microphone and slides (camera optional). Once you have them, you can run as many as you like.

They don't have to be one-and-done either. Record them. Use the recordings as lead magnets. Let your webinars keep pulling people in long after the event.

At my previous software company, we ran a webinar about once a month, and webinars were still one of our top ways of signing up new subscribers.

How to structure a webinar that sells

I used to plan every element to the minute. With more experience, I'm far more relaxed. I generally cover:

An introduction to you and your background. Bonus points for a guest host who introduces you. (It's always better for others to say nice things about you than to brag about yourself.)
Interesting content that isn't readily available online. People are fine with being pitched, as long as they've learned something new first.
Social proof: customers talking about the results they got.
A call to action: sign up, or take the next step, such as a personalized demo.
Q&A. This is the most underrated part. Mine sometimes run an hour past the scheduled finish, and most attendees stay. It's your chance to get unspoken concerns out in the open.

With the call to action, I usually offer a fast-mover discount for signing up within the hour. I only do it when there's a genuine reason: someone who signs up on the spot saves our sales team a follow-up demo, so I pass that saving on. I tell the audience exactly that, and the transparency is always well received.

The 2026 twist: run it live, then cut the recording into short clips for LinkedIn, YouTube Shorts and Instagram Reels. One webinar can feed your social channels for a month. My social media guide covers the platforms in more detail.

Technique #3: Create a customer referral program

Why have a referral program?

Here are the numbers I quoted in the book. After reading them, I hope you'll ask yourself how you could not have one.

In Influitive's report What You Should Know About B2B Referrals, But Probably Don't, 69% of B2B professionals said referral leads close faster than any other kind, and 71% said referral programs have the highest conversion rate of any marketing strategy.
A 2012 Jack Morton Worldwide report found 49% of people first hear about brands from friends or family.
Nielsen found 84% of people trust word of mouth from friends and family more than any marketing message.
Wharton research found a referred customer has a 16% higher lifetime value than a non-referred customer.
Deloitte found referred customers have a 37% higher retention rate.
Churn in referral channels was reported to be 18% lower than in any other channel.

Some of these studies are now several years old, but the direction hasn't changed: people trust people.

And a referral program doesn't cost much. You just need to give existing customers a reason that makes referring worth their time.

There's one caveat. Your service must be everything you promise. Referrals multiply whatever experience you deliver. Break promises, and your customers will disappear faster than you can shake a stick.

Referrals are my favorite shoestring technique, so let me go deeper. Here are six reward strategies.

Strategy #1: One-time cashback

Sometimes you have to spend a little to get a lot.

Payroll and HR platform Gusto runs a "Refer and Earn" program. Customers share a link. The person they refer signs up and gets a free trial. The referrer gets a cash gift card.

Here's the critical part: the gift only goes out once Gusto receives the referred customer's first invoice payment. No payment, no reward. And because the first invoice is always worth more than the gift, Gusto never loses.

Collect from the new customer before you pay the referrer. Simple.

Strategy #2: Free features or upgrades

When I wrote the book, Dropbox gave Basic users an extra 500MB of storage for each referral, up to 16GB. Plus and Professional users got 1GB per referral, up to 32GB. Either way, that's a cap of thirty-two people.

I love two things about this. First, the reward is more of what customers came for. Second, the cap keeps referrals high quality and stops anyone earning so much free storage they never need to pay.

Offer something your users value. Don't offer so much that you shoot yourself in the foot.

Strategy #3: A free month of subscription

Evernote gave points for successful referrals, which customers could trade for a free month or a free year of its personal plan.

The rub? To earn a free period, you had to refer enough people that their subscriptions more than covered it. Evernote wasn't losing out. And points gave it control over how much work a referral took, plus the groundwork for a broader loyalty program.

Strategy #4: Branded swag

T-shirts, mugs, caps. Send them to your best referrers.

The caveat: you need a brand people want on their stuff. Harley-Davidson owners will happily wear the logo. Customers of accounting software... maybe not.

Roses Only, a well-known Australian online florist, famously sold high-quality branded umbrellas below cost. On a rainy day in Sydney, thousands of people advertised the brand for it. Clever play.

Strategy #5: Ongoing referral fees

I've been on the receiving end of this one.

In the early 2010s I used Ontraport, a sales and marketing platform, so much that my agency became an affiliate. For every person we referred, we received 30% of the revenue Ontraport earned from them, for the lifetime of the account. It became a passive revenue stream for us. Later it paid 25% instead.

The caveat: lifetime revenue share eats your margin. Make sure your margins can carry it. I suspect that's why Ontraport trimmed the rate.

Strategy #6: Associated businesses

Years ago I ran a marketing workshop for a group of local dance studio owners. I asked them to list every business they could think of that was associated with theirs.

Art schools. Preschools. Swim schools. Shops selling dance shoes and apparel.

Then I asked them to call each one and suggest a partnership: the studio would refer its clients to every business that said yes, in return for referrals back.

In no time they had a referral network. It cost nothing.

Do the same exercise. Make your list, then pick up the phone, send an email or connect on LinkedIn. Every business that says yes is a new source of clients.

The six referral rewards compared

Reward	Cost to you	Works best for	Watch out for
One-time cashback	Fixed, paid after first payment	B2B services and software with a decent first invoice	Paying before the new customer pays
Free features or upgrades	Low (you give more of your own product)	Products with a usage limit, like storage or credits	No cap, so nobody ever needs to upgrade
A free month	One month of service cost	Any subscription with good margins	Rewards that cost more than the referral is worth
Branded swag	Low to medium	Brands people are proud to be seen with	Merch nobody wants
Ongoing referral fees	A share of revenue for life	Affiliates, agencies and partners who refer often	Margins that can't carry it
Associated businesses	Usually free	Local and service businesses	One-sided partnerships that fade

Worked example: what can you afford to pay for a referral? (illustrative)

Say your subscription is $49 a month, your gross margin is 70%, and customers stay 14 months on average. Each customer brings about $686 of revenue and about $480 of gross profit. Giving both sides a free month costs you two months of service, roughly $29 in delivery cost at that margin (or $98 of forgone revenue). Either way, it's a small slice of $480. Now compare an ongoing 25% referral fee: that's $12.25 a month for life, which takes your 70% margin on that customer down to 45%. Still workable, but you can see why the rate matters.

Dropbox's referral rocket, four years on

Dropbox's referral program is still one of the most copied in software. But referrals can't restart growth once a product becomes a commodity. In Q2 2026 Dropbox reported revenue of $631.5 million, up just 0.9%, and 18.19 million paying users, essentially flat for two years. It's still very profitable, with a non-GAAP operating margin of 39.7%. The lesson: referrals are brilliant for growth, but you need a product that keeps getting more valuable. The Dropbox case study has the full story, and my referral programs guide has more examples.

Technique #4: Use embedded integration to make your service indispensable

Slack has a great value proposition. But a value proposition alone doesn't keep you on top.

So how did Slack keep its position while winning new clients? One of its most important techniques was making itself indispensable by integrating with almost everything. When I wrote the book, Slack connected with more than 2,000 apps, including OneDrive, DocuSign, Google Drive, Dropbox, Outlook, Asana and Trello.

That's huge for winning customers, because Slack becomes the central hub for the tools they already use.

It's even bigger for retention. Think how much work it would take to stop using Slack once it's wired into dozens of apps, plus the cost of retraining your team on whatever replaces it.

Since the book, Slack (now part of Salesforce) has shown what embedded products can do with that position. In June 2025 it folded advanced AI into its Business+ plan and raised the price from $12.50 to $15 per user per month on annual billing. You can only do that once you're the hub. The Slack case study has the details.

You don't need 2,000 integrations. A small business can do this with three:

Connect to their money system. If you're a service business, sync with your clients' accounting software so invoices and data flow automatically.
Connect to their calendar. Bookings, reminders and reschedules that live in their calendar are hard to walk away from.
Connect to their store or CRM. If you sell to online retailers, plug into the platform they already run.

Every connection your customer sets up is one more reason not to leave.

When cheap growth is the wrong move

Low-cost growth is great. But I've seen it backfire, so here are the honest warnings.

Don't grow before you have fit. Referrals and communities amplify what you already have. If customers aren't delighted yet, fix the product first. Cheap acquisition into a leaky bucket is still a leaky bucket. My guide on how to reduce churn is the place to start.
Watch the true cost of "free" channels. Communities, webinars and content cost time. If you're the founder, your hours are the budget. Track where your customers really come from and drop what isn't working.
Don't let rewards eat your margin. Ongoing referral fees and generous free months add up. Run the numbers on customer acquisition cost before you launch.
Be careful with "free" offers in Australia. Free trials and free months that roll into a paid subscription need clear terms. From 1 July 2027, Australia's new subscription rules require notices during a subscription, expected to include reminders before free or discounted trials end and before renewals. The timing is left to regulations that, as at October 2026, hadn't been made, so check the final regulations. My guide to Australia's subscription trap laws explains what's coming. This is general information, so get advice on your own sign-up flow.

2026 update: what's changed in shoestring growth

The book's techniques still work. Here's what I'd add today, based on the research behind this site.

Capital-efficient companies are reaching serious scale. Among the 44 companies in our research that were reported to have crossed about $100 million in run-rate revenue in 2026, turbopuffer got there having raised less than $1 million, according to ARR Club. Horatio is fully bootstrapped. Capacity grew about twentyfold in three and a half years without what it called "excessive funding." These are self-reported milestones, but they show you don't need a war chest.

Free entry is almost universal at the self-serve end. Thirteen of those 44 companies have a permanent free tier or free product. The free tier is the marketing budget.

Your customers' output can be your marketing. Scribe's guides, Emergent's clonable apps and Meshy's attribution license all spread the brand every time a customer shares their work. Ask: what do my customers make with my product, and can it carry my name?

Publishing your prices does the selling. Owner, which sells online ordering to restaurants, publishes two plans and the break-even between them: Flexible at $249 a month plus 5% per order, or Flat Rate at $499 a month, which cost the same at $5,000 of monthly online sales. A clear calculation replaces a sales call.

AI makes content cheaper, so quality and originality matter more. Anyone can now produce a blog post in minutes. That means generic content gets you nothing. First-hand stories, real numbers from your own customers, and genuinely useful tools are what get shared, ranked and quoted by AI assistants.

Community is the moat against algorithm changes. Social reach rises and falls with each platform's latest change. An email list, a group and a customer base that refers you are channels you own.

How will you grow your subscription service? What to do next

I've given you four techniques I still use, six referral rewards and 50 more ideas. One of them is the technique I think is the most effective when you don't have bags of cash. (Hint: it's the one that took up most of this page.)

Here's a simple 30-day plan:

Week 1: Launch a referral offer to your existing customers. One reward, paid after the referred customer's first payment.
Week 2: Make your associated-businesses list and contact the first ten.
Week 3: Run one webinar. Record it and cut five short clips from it.
Week 4: Start a small community for your best customers, and pick three integrations that would make you harder to leave.

Then pick five strategies from the list of 50 and give them a proper go for a quarter.

If you're still deciding what to sell, my guide to starting a subscription business with no money is the place to begin.

Action exercise: Which of these growth strategies will you put in place first? Write down your referral reward, your first ten partner businesses and the date of your first webinar. Then move to the next chapter: once you have 'em, how will you keep 'em coming back?

Frequently asked questions

What is the cheapest way to get subscribers?

Usually your existing customers. A referral program that pays only after the referred customer's first payment costs you nothing until it works. Close behind are a free community, recorded webinars used as lead magnets, and partnerships with businesses that already serve your ideal customer. Paid ads can work on a small budget, but test them after these free channels, not before.

How much should I pay for a referral?

Work backwards from margin. Estimate the gross profit a typical customer brings over their lifetime, then decide what share you'd happily spend to win one. Many businesses give one free month or a small credit to both sides. Make sure the reward is paid only after the new customer pays, and that ongoing referral fees still leave you a healthy margin.

Should a small subscription business run paid ads?

Only once you know your numbers. You need to know what a customer is worth over their lifetime and roughly how many will churn. Start with a small daily budget on one platform, send traffic to a single offer, and stop anything that can't pay back within a few months. Free channels usually give you better first customers.

Do webinars still work for getting subscribers in 2026?

Yes, especially for B2B and higher-priced subscriptions where people want to see the product and ask questions. What has changed is distribution. Run the live session, then cut the recording into short clips for LinkedIn, YouTube Shorts and Reels, and keep the full replay as an always-on lead magnet on your site.

How do I get my first ten subscribers with no budget?

Go where your ideal customers already gather and be useful. Answer questions in their groups and forums, offer a founding-member price to the first ten, ask friends and associated businesses for introductions, and personally onboard every one of them. Your first ten customers are also your first testimonials and referrers.
