How Ajay actually did it

7/7 funnel stages sourced

Reconstructed from Ajay's own published sources. Quoted claims are the founder's words, verified verbatim; anything marked as our analysis is exactly that.

Where the idea came from

Personal painPivot from Wordzen (a Gmail-based service connecting users with freelance writers/editors); GMass grew out of the communication problem he hit while recruiting for it. He had also already built and sold a prior email marketing company, JangoMail, in 2013.20y domain experience

Goel built the first version of GMass out of his own frustration at needing to email several candidates about an open position at his company (he was recruiting writers/editors for his other Gmail-based product, Wordzen, at the time) without exposing them to each other or using BCC. In a separate, more detailed account he adds that he assumed a Gmail mass-email tool already existed and was surprised to find none did, after having just sold his prior company, JangoMail, in 2013.

“I started researching and building GMass out of my own frustration one day while needing to email five different candidates about an open position at my company.”

Introducing GMass (GMass Blog, Ajay Goel)

Validation

Built first, validated after

MvpValidated

Built the first version of the Chrome extension and a C#/SQL Server backend with a paid freelancer in about two weeks, then launched publicly with no prior landing page, waitlist, or presale validation.

He specified the front end and back end himself and paid a freelancer $5,000 to build the backend within seven days, producing a working prototype in about two weeks total.

“I built the first version of GMass with the help of a freelancer in about two weeks.”

First test users

Online communityFree testers

The earliest wave of users came from a Reddit post announcing GMass on r/startups at the end of August 2015, which became the top thread on that subreddit for about a day, followed within weeks by a Product Hunt launch in September 2015.

“My reddit thread was the #1 thread on r/startups for about 24 hours, which drove some of the initial signups.”

How I Hit $115k/mo with a Status Quo Improvement (Indie Hackers interview)

First paying customer

UnknownFree to paid upgrade

GMass was free for everyone for roughly its first year. The first paying customers were existing free users converted when Goel switched on payment plans; he does not name which acquisition channel the very first payer came through, only that he watched for the first subscription notification after flipping the switch and none arrived for several hours.

“I sat in front of my email, reloading and reloading, waiting for the first notification to arrive of a new subscriber.”

How I Hit $115k/mo with a Status Quo Improvement (Indie Hackers interview)

Acquisition channels, and whether they worked

Communities · r/startups (Reddit)LaunchWorked

Announced GMass on the r/startups subreddit at the end of August 2015, back when naming and linking your own product there was still allowed.

“I first announced GMass on the startups subreddit at the end of August 2015.”

How I Hit $115k/mo with a Status Quo Improvement (Indie Hackers interview)

The thread's ranking on the subreddit for about a day drove a meaningful share of the earliest signups.

“My reddit thread was the #1 thread on r/startups for about 24 hours, which drove some of the initial signups.”

How I Hit $115k/mo with a Status Quo Improvement (Indie Hackers interview)

Product HuntLaunchWorked

Launched GMass on Product Hunt in September 2015, shortly after the Reddit announcement.

“I launched GMass on Product Hunt in September 2015, which was a huge success.”

How I Hit $115k/mo with a Status Quo Improvement (Indie Hackers interview)

The Product Hunt feature itself was the driver of the spike; he does not attribute it to any specific tactic beyond the launch happening.

“It drove a ton of traffic and user signups exploded, with a new account being created every three minutes.”

How I Hit $115k/mo with a Status Quo Improvement (Indie Hackers interview)

SEO / Content · Chrome Web Store listing ranking for "mail merge"First customersWorked

Noticed GMass ranked #4 for the Chrome Web Store search term "mail merge" (only the top three results showed), identified that one of the top three was an abandoned, unsupported competing product, and asked its developer to remove the listing.

“I contacted the developer of that tool and gently asked if he would be so kind as to remove his product entirely, and explained why.”

How I Hit $115k/mo with a Status Quo Improvement (Indie Hackers interview)

The competing developer agreed to remove his listing, which improved GMass's visibility in that search result.

“Surprisingly, he said yes.”

How I Hit $115k/mo with a Status Quo Improvement (Indie Hackers interview)

SEO / Content · Free web tools and content built to draw organic search trafficScalingWorked

Runs SEO and content as GMass's largest ongoing cost center after AWS hosting, staffing it with one freelance marketer and two SEO firms, and drives traffic by building free standalone tools (an inbox/spam/promotions placement checker, a domain deliverability statistics database) rather than relying only on articles.

“The next biggest expenses are marketing and SEO related. I have one freelance marketer and two SEO firms working on GMass's behalf.”

How I Hit $115k/mo with a Status Quo Improvement (Indie Hackers interview)

States his explicit growth strategy is to keep building more free tools on the website specifically to attract more search traffic.

“My strategy for accomplishing all this is to build more tools for our website in order to attract more traffic.”

What didn't work

Tech choiceLaunchCost: time

The first version of GMass sent every email in a single synchronous loop rather than asynchronously.

“Because I had everything running in a simple loop, the Gmail interface would hang for minutes upon minutes while the emails sent.”

How I Hit $115k/mo with a Status Quo Improvement (Indie Hackers interview)

The synchronous design surfaced as soon as someone tried to send to a larger list (around 1,000 addresses), freezing the Gmail interface for minutes at a time, which was a poor user experience.

“the first sign of trouble came when someone wanted to send to 1,000 addresses”

How I Hit $115k/mo with a Status Quo Improvement (Indie Hackers interview)

What they did instead: Rearchitected sending to be asynchronous, one of the first major changes made after the initial launch, before later adding scheduling and open/click tracking.

TeamFirst customersCost: time

About six months after launch, the freelance developer who had built and maintained GMass's C#/.NET backend quit.

“About six months after launch, my lead developer emailed me to tell me he was quitting.”

How I Hit $115k/mo with a Status Quo Improvement (Indie Hackers interview)

Goel's own hands-on skills had gone stale (he only knew older classic ASP and VB6), so he had no one else who could pick up the C#/.NET codebase the departing developer left behind.

“I knew classic ASP and VB6. I did not know how to program in .NET and C#, and that's what GMass had been built on.”

How I Hit $115k/mo with a Status Quo Improvement (Indie Hackers interview)

What they did instead: Taught himself the existing codebase and C# so he could make changes himself going forward, and became GMass's de facto lead developer from then on.

How it changed as they grew

At launch: 2 people (Ajay Goel (solo founder, wrote the front-end and back-end specs and built the Chrome extension front end himself) plus one paid freelance developer hired to build the C#/SQL Server backend.)

Today: 7 people (Ajay Goel (Founder) plus 6 named staff shown on GMass's public team page: a VP of Content, a Head of Technical Support, a Head of Deliverability, a Chief of Staff, a PPC Manager, and a Video Content Creator.)

Pricing restructure: Free for everyone → Paid monthly subscription plans, roughly $7 to $20 per month

Started charging about a year after launch specifically to cut down on the spammers a free, unmonitored mass-email tool was attracting; an FBI agent had told him GMass had become a go-to tool for scammers.

“The main reason I started charging was to cut down on spammers using the system.”

How I Hit $115k/mo with a Status Quo Improvement (Indie Hackers interview)

Pricing increase: Standard $25/mo, Premium $35/mo, Professional $55/mo (monthly billing) → Standard $29.95/mo, Premium $39.95/mo, Professional $59.95/mo (monthly billing)

Framed as only the third price increase in GMass's 10-year history, tied to a year of unusually fast feature shipping (AI template builder, dedicated cold-email sending server, unlimited follow-ups, AI spintax, open-rate accuracy upgrades) that he says makes the product do far more than it did 12 months earlier.

“This is only the third price increase in our 10-year history”

Upcoming Changes to GMass Pricing (Jan 2026) (GMass Blog, Ajay Goel)

What broke as they grew

Names Gmail-interface dependency as an ongoing structural risk: GMass works by modifying the Gmail UI in ways Google does not officially support, so every Gmail code update is a fresh chance for GMass to break.

“Google regularly updates Gmail's code, which results in GMass breaking, and it's a constant battle to keep up with the changes.”
