Vacation Tracker
👤 Lav Crnobrnja (Ran Cloud Horizon, a 40-person dev agency; it funded the build, staffed it, and was the first team to feel the spreadsheet pain.)🌐 siteLinkedIn
A dev agency built a PTO tracker for its own spreadsheet pain, grew it Slack-first to about $3M ARR, no VC.
Will it work? · our read
Won on channel. The product is a cheap PTO tracker. What worked was going Slack-first for distribution and writing only high-intent content. Copy the channel discipline, not the feature.

03Weight class — CENTStap an axis
Control Low
Depends on Slack/Teams marketplaces — the platform owns the channel and can build PTO natively.
04The key move
Slack-first by design
Rivals built a web app and added a Slack alert on top. Vacation Tracker inverted it — request, approval, the whole flow lives inside Slack. That turned the Slack App Directory into a free storefront.
fact
The counter-intuitive move
Platform-native distribution cuts both ways — Slack could ship PTO itself, and Vacation Tracker had to rebuild the whole flow again for Teams and Google.

05Where the moat is
The moat is not the feature — it is distribution across three marketplaces plus ranked content.
Presence in Slack, Teams and Google marketplacesContent library ranking for leave/PTO queriesBrand logos (Pepsi, Dell, NBC) as social proofCross-platform depth: accruals, policies, ADP
06How it diesmedium confidence
Slack, Teams, or an all-in-one HRIS like Gusto or Deel bundles PTO tracking for free, and a $2-4-per-user single-feature tool has no reason to exist once a team buys the suite that already includes it. our read
Show evidence · counter
Evidence: Slack and Teams already ship basic reminders; Gusto, Rippling and Deel include PTO inside their HR suites at no extra charge.
Counter: They now span Slack, Teams, Google Workspace and ADP, have moved upmarket to enterprise logos, and leave rules (accruals, per-country policy, approvals) run deeper than a suite's PTO checkbox.

★Would it work for you?
Is there a platform marketplace (Slack, Shopify, Notion, Chrome) where your buyers already gather, so distribution is built in?
A channel that hands you buyers beats a better feature. Vacation Tracker's was Slack. We don't score you — you answer.

<case name="Vacation Tracker" model="saas">
What it does: Vacation Tracker sells a per-user subscription to track PTO and leave requests inside Slack, Microsoft Teams, and Google Workspace.
Why it won (moat): Its edge is distribution: native presence in three chat-platform marketplaces plus a content library that ranks for leave-management searches.
Weakest axis (CENTS): The product is a thin, cheap single feature that a full HRIS or the chat platforms themselves can replicate or bundle for free.
How it could die: It dies if Slack, Teams, or all-in-one HR suites bundle PTO tracking natively, removing any reason to pay for a standalone tool.

<task>
Be a skeptical operator, not a cheerleader. No generic startup platitudes. If my angle is weak, say so plainly.
First, a reality check: markets like this mostly fail. State the honest base rate (how crowded/hard is this?) and the ONE specific thing that would have to be true for ME to be the exception — grounded in my profile above.
Then a compact table:
- Fit — does this pattern suit my edge, or fight my gap?
- Angle — my sharpest differentiation vs Vacation Tracker (concrete, not "better UX")
- Distribution — exactly where my first 100 users come from (this is the hardest part — be specific, not "content marketing")
- Risk — its "how it dies" (above) in MY situation
Finish with one line: "The single thing to do next."
Use only the facts above; if data is thin, say so — never invent numbers.
Then stay with me and go deeper on whatever I ask — tech stack, rough cost & time, the smallest MVP to test, pricing, or timing.

Vacation Tracker — 0 to $3M ARR (company blog, Dec 2025)vacationtracker.io — homepage (3,500+ companies, brand logos)vacationtracker.io/pricing — Free / Core $2 / Complete $4 per userLav Crnobrnja — LinkedInVacation Tracker — Q&A with CEO Lav Crnobrnja
Revenue (about $3M ARR) is founder-stated on the company's own blog (Dec 9, 2025 post: "approaching $3M ARR") — sourced STATED, first-party but self-reported, not a filing or audit. An earlier SaaS Club podcast (Aug 2024) had the founder citing about $2M ARR, so the number has grown; this card reflects the fresher figure. The 3,500+ companies and $2-4/user pricing come from the company's own site and pricing page (2026). I could NOT confirm an Inc 5000 / Deloitte Fast 500 listing for Vacation Tracker, so despite the requested award/ranking angle this is a documented-growth bootstrapped case, not a verified ranking winner — flagging that honestly rather than fabricating a placement. The Slack-first move is documented in the CEO's own Q&A (vacationtracker.io/blog/qa-with-vacation-tracker-ceo) — he says they focused on building around Slack and consider their Slack bot superior to competitors', paraphrased here rather than quoted verbatim. The "free storefront" framing and the HRIS-bundling death scenario are [our read]. No invented drama — they won on channel choice and intent-driven content, not a single dramatic bet. We never score you.
