Robinson Grew Retention.com to $23 Million ARR Without VC

By Amara Osei

Retention.com reached about $23 million in annual recurring revenue within a few years of its November 2019 launch, according to Adam Robinson. The bootstrapped email-marketing company grew from a feature Robinson built inside Robly while operating without venture capital.

Robinson described the sequence in a 2024 interview. He started Robly in the highly competitive email-marketing and automation market, sold it in 2021, and had already begun developing his next business before the acquisition.

Robinson said Robly's limited resources made it difficult to compete with larger companies. He searched for services larger rivals were unwilling or unable to provide, and the visitor-email technology became his opening.

How did Robinson build without venture capital?

Robinson said he did not rely on outside investors. He used cash generated by Robly to develop GetEmails, which later evolved into Retention.com.

Robly had nine employees when acquired. At the sale, the company generated about $3 million in ARR and $1.5 million in earnings, according to Robinson.

Robinson said 45% of Robly belonged to him, alongside three co-founders. He also said all nine employees stayed with the acquired business for three years after the 2021 transaction.

He built GetEmails to match Robly's financial performance, he said. That would let him move away from Robly without taking an income hit.

What did the visitor-identification technology do?

Robinson said he found a technology that identified email addresses belonging to website visitors. It worked even when visitors did not complete a contact form.

He said the practice was initially operated and permitted in the United States, while Europe excluded it. Robinson introduced the capability as Robly ID inside Robly's existing platform.

Robinson said customers had to download files and transfer them to another system, making the workflow lengthy. Despite that friction, he said customers gave favorable reviews, and some agreed to pay 25 cents per lead.

Why did Robly ID become a separate business?

Robinson said he eventually decided to separate Robly ID from Robly. He wanted the technology to work with multiple email-marketing platforms and support a larger business rather than remain confined to the original platform.

Robinson said the standalone product launched in November 2019 as GetEmails. It later evolved into Retention.com, which reached approximately $23 million in ARR within a few years.

The 2024 interview framed Retention.com's $23 million ARR as a step-change from Robly's roughly $3 million at sale. Robinson said cash generated by Robly supplied the financial base for the second build.

What funded the second venture?

Robinson said he bootstrapped the second company with cash generated by the first. The model tied development to Robly's earnings rather than a new venture-capital round.

The first business therefore served two purposes in Robinson's account. Its $1.5 million in earnings at sale set a benchmark, while its cash generation funded GetEmails and then Retention.com.

The origin of Retention.com was direct. Its core technology had already been tested inside Robly, reviewed by customers and packaged as Robly ID before becoming a standalone product.

No outside investor appears in Robinson's account of the build-out. He recycled cash from Robly into a product that identified website visitors' email addresses across more platforms.

What does the growth strategy show?

Robinson's route depended on releasing Robly ID inside an existing business before widening distribution. It moved from one platform to several, and from Robly to Retention.com, without outside venture capital.

Robinson's model produced approximately $23 million in ARR from a company that began as a spinout and a second business funded by the first. The next test is whether the bootstrapped model can sustain further growth across a broader set of email-marketing platforms.
