In short

A niche inside a niche inside a niche let one non-developer founder plausibly reach the whole market by hand. Reilly Chase didn't target "Ubiquiti users" — he targeted the specific slice of IT/MSP businesses that resell Ubiquiti hardware, a market small enough that DMs, forum signatures, and one Twitter account could plausibly cover it.
Six months of forum grinding mostly failed — the SEO ranking that quietly built up alongside it is what actually worked. Of 25–50 cold DMs pitching "cheapest hosting," only 3–4 people replied; meanwhile the site's domain aged into the #1 organic spot for "UniFi cloud hosting" by around December 2018, in a market with only 1–2 competitors.
MRR went $5 to $10,000 in 15 months, then Ubiquiti itself created the biggest growth spike by shutting down its own competing product. $5 MRR (Jun 2018) → $2,500 (Dec 2018) → $8,333 MRR / $100K ARR (Jul 2019) → $10,000 MRR (Sep 2019); when Ubiquiti quietly killed UniFi Cloud in Nov 2019, HostiFi was the alternative already sitting at the top of search results.
The usual "hustled his way to $10K MRR" telling undersells how much depended on Ubiquiti's own exit, not just Reilly's forum hustle. The founder's own numbers show his manual outreach converted poorly — his SEO position and the 2019 shutdown windfall did more of the work than the DMs and forum posts most retellings focus on.

The mechanism

HostiFi's growth chain runs: choose a niche so narrow (IT/MSP resellers of one hardware brand) that a single founder's manual outreach can plausibly cover it — that narrowing is why forum DMs and a Twitter account were even a rational strategy; let a slow-building SEO position compound in parallel, because the manual outreach itself converted poorly (3–4 replies out of 25–50 DMs) and needed a channel that didn't depend on being liked back; then be the party already sitting at the top of the search results when the actual incumbent (Ubiquiti's own cloud hosting) shut itself down in November 2019, turning a niche SaaS into the default landing spot for an entire migration wave it did nothing to create.

Picking a niche inside a niche inside a niche made a single founder's forum hustle add up to real market share

HostiFi didn't compete for "network admins" or even "Ubiquiti users" — it targeted the much smaller set of IT/MSP businesses and WISP operators who resell Ubiquiti hardware and need to manage many customers' networks from one place. That narrowing is why one person cold-DMing forum members and replying to Twitter mentions could plausibly reach a meaningful share of total demand, instead of being a rounding error against a market too large for one person to touch.

It's a niche within a niche within a niche. Ubiquity is a billion-dollar company... I've kind of targeted one specific group of people who buy their hardware which is IT service providers.

The manual outreach mostly failed — which is why the SEO position that built up in parallel is the real explanation for early growth

Chase sent 25–50 direct messages to forum members pitching "cheapest hosting" and got only 3–4 replies; he was also banned or reprimanded on several channels after spamming Reddit, Ubiquiti forums, and Facebook groups at launch. What did compound was slower and quieter: because the domain had months to age and the search term "UniFi cloud hosting" had only 1–2 real competitors, the site worked its way onto page one and then to the #1 organic spot by around December 2018 — the same month MRR crossed $2,500. That ranking, not the DM volume, is why traffic kept arriving even after the manual hustle stopped converting.

I was like thinking people want the cheapest thing... I sent a message like hey, we have the cheapest hosting for this thing and I didn't try to make relationships with people.

Occupying the #1 search result is what let Ubiquiti's own shutdown become HostiFi's biggest single growth event

In November 2019, Ubiquiti quietly shut down its own UniFi Cloud hosting service — removing the one alternative to HostiFi that carried the incumbent's own brand trust. Because HostiFi already held the top organic position and an active Twitter presence built from two years of niche engagement, the resulting migration demand had nowhere else obvious to land. The windfall only paid off because the positioning work from links 1 and 2 was already in place when it happened; arriving late to the same keyword with no ranking history would have missed the spike entirely.

Ubiquiti had quietly shut down their own UniFi cloud hosting service.

How it went

Side-project launch and a forum-spam hustle that mostly didn't work

2018-05 → 2018-07

Reilly Chase, a network/VoIP engineer with no professional software background, built HostiFi's MVP on WordPress plus custom Python scripts (he couldn't get Django or Flask working) as a side project of his IT services business, Locklin Networks. At launch he spammed Reddit, Ubiquiti's own forums, and Facebook groups — getting banned or reprimanded on several — and sent 25–50 direct messages pitching "cheapest hosting," which drew only 3–4 replies. His first paying customer signed up June 1, 2018 for $5/month from the Netherlands; by July he had 25 paying customers and $300 MRR, helped along by early Google Ads bids on "UniFi hosting" search terms and a Twitter account built by following and replying to anyone discussing Ubiquiti or UniFi.

SEO quietly compounds while the day job runs out

2018-07 → 2019-01

As the domain aged, HostiFi's site climbed Google's rankings for "UniFi cloud hosting" — a term with only 1–2 real competitors — reaching page one and then the #1 spot by around December 2018, the same month MRR crossed roughly $2,500. In January 2019, Reilly's employer discovered his side business and fired him for moonlighting as a security analyst. He applied to Calm Company Fund (run by Earnest Capital) despite being below their typical MRR threshold, was accepted, sold his house to extend his runway, and used the roughly $100K investment to go full-time.

Full-time rebuild, first hire, burnout, and the Ubiquiti windfall

2019-01 → 2019-11

Full-time and funded, Reilly spent 2–3 months rewriting the platform from WordPress to Laravel Spark, publishing $5,735 MRR / 266 subscribers / 309 servers in a May 2019 post. He hit $100K ARR (~$8,333 MRR) in July 2019, meeting a challenge from SaaS Club host Omer Khan to earn a podcast slot. Running the business alone caught up with him on a five-day camping trip in August, which he describes as a breaking point; by September MRR passed $10,000. In September 2019 he hired Safwan Shaikh, an ex-Ubiquiti employee, as his first employee — within weeks Safwan was handling 80%+ of support tickets, freeing Reilly for development. In November 2019, Ubiquiti quietly shut down its own UniFi Cloud hosting service; HostiFi, already ranked #1 for the relevant search terms, absorbed the resulting migration demand.

Seven years of compounding into a 10-person, 5,000-customer business

2019-11 → 2026-08

Sources don't document a detailed month-by-month path for this stretch, but the endpoint is stated plainly on HostiFi's own homepage as of August 2026: the company has grown to over $3M/year in revenue with a team of 10 people serving more than 5,000 customers and carrying 300+ Google Reviews, still built around the same UniFi/UISP cloud hosting niche it launched with in 2018.

Whether it fits you

HostiFi's loop depended on market structure and personal risk tolerance that won't transfer to every niche SaaS. Run it if these hold for you; the costs are real.

What it needs

Your addressable market needs to be small enough that one person can plausibly reach most of it

HostiFi's forum DMs, Twitter replies, and signature posts only worked as a strategy because the real buyer group — IT/MSP businesses reselling one hardware brand — was small enough to be enumerable by hand. The same manual tactics against a market ten times larger would have been noise, not a channel.

You need a category where the biggest incumbent might blunder, exit, or shut down a product line — and the patience to wait for it

The single largest growth spike in HostiFi's history wasn't a tactic Reilly ran — it was Ubiquiti shutting down its own competing cloud service in November 2019. Capturing that required already occupying the #1 search position for over a year beforehand; you can't retroactively build the ranking once the windfall arrives.

You need real personal runway (savings, or a spouse's income, or something to sell) to survive a forced full-time transition

Reilly didn't plan his transition to full-time founder — he was fired in January 2019 for moonlighting, and sold his house to extend his runway before the business was reliably profitable. This path assumes you can absorb that kind of shock without the business folding.

What it costs

Early manual outreach mostly fails, and can get you banned from the exact communities you need

Of 25–50 cold DMs pitching "cheapest hosting," only 3–4 people replied, and launch-week spamming on Reddit, Ubiquiti forums, and Facebook got Reilly banned or reprimanded on several channels. Expect a low hit rate and some reputational cost before you learn a better approach.

Revenue scales with fixed per-customer infrastructure costs, not classic high-margin SaaS economics

Each HostiFi customer gets a dedicated cloud server, so costs scale roughly linearly with customers rather than staying flat as a typical multi-tenant SaaS product's would. At ~$8,300 MRR, server and advertising expenses alone ran $2,500–$3,000/month.

The founder absorbed direct personal financial risk before any institutional funding arrived

Being fired and selling a house for runway happened before, not after, the $100K Calm Company Fund investment. Anyone copying this path needs to be honest that the safety net came late and was self-funded through personal risk, not de-risked by outside capital from the start.

The numbers we could verify

expenses: At ~$8,300 MRR, expenses for servers and advertising ran $2,500–$3,000/month (S4).
cost structure: Costs scale roughly linearly with customers because each customer gets a dedicated server — not a traditional high-margin multi-tenant SaaS cost structure (S4).
infrastructure: Runs entirely on Vultr, chosen for its number of data center locations (S4, S6).
outreach conversion: 25–50 cold forum DMs pitching 'cheapest hosting' produced only 3–4 replies (S4).

Our read

The common shorthand for this story is 'founder hustled his way from $5 to $10K MRR' — but Reilly's own numbers undercut that: his manual DM and forum-spam outreach converted at roughly 3-4 replies per 25-50 messages sent, and got him banned from some of the very channels he was targeting. The actual engine underneath the hustle was a slow-building SEO position in a market with almost no competitors.

The single biggest growth event in HostiFi's history — Ubiquiti shutting down its own UniFi Cloud service in November 2019 — wasn't something HostiFi did at all. It's a reminder that 'growth teardown' narratives built entirely around founder tactics can miss that sometimes the biggest lever is being positioned to catch a windfall you didn't create.

The forced nature of Reilly's full-time transition (fired, then sold his house) makes this a survivorship story as much as a strategy story. The mechanism links are real and repeatable, but the personal-risk path that got him to full-time is not something to recommend as a deliberate plan.
