How TinySeed Bootstrapped a SaaS Accelerator for Indie Founders

Lucas: So back in 2018, if you were a bootstrapped SaaS founder - profitable, growing, say a hundred thousand in annual recurring revenue - your options for outside capital were basically zero. Traditional VCs wanted hockey-stick growth and a big equity stake. Bank loans? No revenue, no collateral.

So you either stayed small or you took the VC path. Luna: Right, and that gap is exactly what Rob Walling and Einar Vollset set out to fill with TinySeed. Lucas: Exactly. TinySeed launched as the first accelerator built specifically for bootstrapped SaaS companies.

And the model was genuinely different. Instead of the typical three-month program with a $20,000 check for 7 percent equity, TinySeed offered a year-long remote program with $120,000 upfront - structured as a revenue-based note. Luna: A revenue-based note meaning the founders repay a percentage of revenue over time, capped at a multiple, rather than giving up equity. Lucas: Right.

So the cap was usually 1.5x to 2x the principal. If the company grows fast, the repayment happens faster. If it grows slowly, you have more time.

No board seats, no liquidation preference, no pressure to sell. It was a radical idea at the time. Luna: And it came out of a real pain point Rob Walling had experienced himself. He'd been a bootstrapped founder for years with projects like Drip - a marketing automation tool - and later sold it.

He knew the landscape. Lucas: Yeah, Rob and Einar basically designed the accelerator they wished had existed when they were starting out. The announcement came via a podcast episode of 'Startups for the Rest of Us' - the show Rob co-hosts. They said, we're looking for 10 companies to pilot this.

Luna: And they got something like 300 applications for those 10 spots. Lucas: Exactly. The demand was huge. In the first cohort, they had companies like ConvertKit - which was already doing well but wanted to accelerate - and other B2B SaaS tools.

The program combined funding with a structured curriculum: monthly sprints, peer masterminds, and one-on-one coaching from mentors who actually built bootstrapped businesses. Luna: No flashy demo days pitching to VCs. Just steady building. Lucas: No demo day.

That's a key differentiator. TinySeed didn't want founders to waste time on a pitch deck. Instead, the program focused on metrics that matter for sustainable growth: monthly recurring revenue, churn, customer acquisition cost. The kind of numbers that tell you if the business is healthy.

Luna: And the remote-first structure was also ahead of its time. Back in 2018, fully remote accelerators were rare. Lucas: Yeah, TinySeed was remote from day one. That meant founders could stay in their own city, keep their cost structure low, and not uproot their families.

The cohort model still gave them a strong network - they had weekly calls, a Slack community, and in-person retreats twice a year. Luna: So what kind of companies actually got in? You mentioned ConvertKit - now called Kit - which was already doing around $500,000 in annual recurring revenue when they joined TinySeed. Lucas: Right.

ConvertKit is probably the poster child. Founder Nathan Barry bootstrapped it from zero. By the time he applied to TinySeed, he had a solid business but wanted to professionalize the go to market. The $120,000 note gave him the runway to hire a head of growth and invest in content marketing without diluting his equity.

The company later hit over $30 million in annual recurring revenue before being acquired in 2022. Luna: And ConvertKit wasn't the only success. There's also companies like Tally - a no-code form builder - and Pabbly, which does subscription billing. They all grew revenue significantly after the program.

Lucas: Yeah, TinySeed's own data from their first few cohorts showed that companies in the program saw median revenue growth of about 2.5 times over the year. That's solid. Not unicorn-level, but sustainable.

And importantly, the founders retained full ownership. Luna: But what about the fund itself? TinySeed started as a single fund of about $4 million from Rob and Einar's own money and a few angel investors. How did they scale?

Lucas: They raised a second fund in 2020 - around $10 million - and a third in 2022. By 2024, they had invested in over 80 companies across multiple cohorts. The structure evolved too: later cohorts offered $120,000 or $240,000 notes depending on the company's stage. But the core philosophy stayed the same: patient capital for bootstrappers.

Luna: I want to circle back to the revenue-based note model. It's not without risks. If a company grows very slowly, the note can take years to repay, and the fund's returns suffer. How has that played out?

Lucas: It's a valid question. The fund's returns depend on a few breakout companies. Rob Walling has been transparent that not every company will be a home run. But because they're investing at a very early stage - typically companies with $5,000 to $20,000 in monthly recurring revenue - the upside can be significant.

A few companies hitting $1 million in annual recurring revenue can repay the whole fund. And because there's no equity, the founders are motivated to grow profitably, which aligns incentives. Luna: It seems like TinySeed filled a real gap. But have other accelerators copied the model?

Lucas: A few. Indie.vc was another early pioneer, but they shut down in 2020. There's also Earnest Capital, which does convertible notes with a revenue share.

But TinySeed is probably the most well-known. What's interesting is that TinySeed also spawned a community - they have a podcast, a conference called MicroConf, and a huge Slack group. So the accelerator became the hub for an entire movement. Luna: And that's a model in itself: build a product, but also build a community around it.

Lucas: Exactly. If today's episode gave you a few useful ideas about alternative funding models, that's exactly what we're going for. The show stays ad-free because of listeners who find value in it and choose to support - you can do that at buy me a coffee dot com slash fexingo. It's a simple way to keep these conversations going.

Luna: Yeah, it genuinely makes a difference. I've seen how much it means to have that support. Lucas: Alright, back to TinySeed. One critique I've heard is that the revenue-based note can be expensive if your company grows fast.

The 1.5x to 2x cap means you're effectively paying a high interest rate relative to traditional debt - but you only pay if you have revenue to pay from. So it's not like a bank loan that requires fixed monthly payments regardless of cash flow. Luna: Right, the payment is a percentage of revenue, typically 5 to 10 percent.

So in down months, you pay less. That flexibility is huge for bootstrapped founders. Lucas: And the cap protects founders from infinite liability. If the company exits big, the note pays off early.

If the company chugs along, you pay the cap and then you're done. The average repayment period was around three to four years for TinySeed's early cohorts. Luna: So what do you think - is TinySeed's model replicable for other industries, or is it SaaS-specific? Lucas: It's definitely easier in SaaS because revenue is predictable and recurring.

You can track monthly revenue and automate the repayment. For a physical product company with inventory, seasonality, and lumpy revenue, it's much harder to structure a revenue-based note. But the principles - patient capital, no dilution, founder-friendly terms - could apply to any bootstrapped business if the investors are willing to take a long-term view. Luna: And TinySeed has proven that there's a viable path between bootstrapping and VC.

It's not either-or. Lucas: Exactly. For a generation of founders who want to build profitable, lasting companies without giving up control, TinySeed showed that alternative capital exists. And that's a lesson that goes beyond any single accelerator.
