Written by Huifer, solo developer and maintainer of TanStack Ship. I took TanStack Ship from 0 to 100 paying customers over Q1-Q2 2026 using only the eight levers in this post. No paid ads until month 4. No marketing hire. No growth team. Just the framework, the measurement, and a willingness to ship a blog post a week for 12 weeks straight.

TL;DR: The eight levers below — UTM attribution, referrals, content, community, email, paid (when ready), and measurement — are the minimum viable growth stack for an early-stage SaaS. None of them require a marketing hire. All of them can be built on a TanStack Start + Cloudflare Workers starter in a weekend. The order matters: ship attribution first, then referrals, then content, then community, then email, then paid (only if the others plateau). Measurement is the thread that ties them together — without it, you cannot tell which lever is working.
The Growth Stack: Tools and Systems You Need
The "growth stack" for a sub-$10k MRR SaaS is six things: an analytics tool (PostHog or Plausible), a UTM-aware link shortener, an email tool (Resend or Loops), a referral program, a content publishing flow, and a community presence. Each one ships in TanStack Ship by default.
The mistake first-time founders make is over-investing in any one of these. A $500/month Mixpanel plan at 0 customers is wasted money. A $200/month ConvertKit at 0 customers is wasted money. Start with the free tiers of everything. Upgrade only when you have signal that the upgrade is buying something measurable.
What you cannot skip: UTM attribution. Every other lever in this post depends on knowing which touchpoint brought the customer. If you skip UTM tracking on day one, you cannot retroactively attribute the 47th customer. You will spend months guessing which blog post, which tweet, which Hacker News comment did the work. Spend the four hours on UTM middleware before you write your first growth post.
UTM Attribution: Track Every Touchpoint From Day One
UTM parameters are five tags (utm_source, utm_medium, utm_campaign, utm_term, utm_content) that you append to URLs to identify where the click came from. The middleware captures them, persists them to a cookie, and attaches them to every signup event.
// src/middleware/utm.ts
import { createMiddleware } from '@tanstack/start'
const UTM_KEYS = ['utm_source', 'utm_medium', 'utm_campaign', 'utm_term', 'utm_content'] as const
const UTMS: Record<string, string> = {}
export const utmMiddleware = createMiddleware().server(({ next, request }) => {
const url = new URL(request.url)
for (const k of UTM_KEYS) {
const v = url.searchParams.get(k)
if (v) UTMS[k] = v
if (UTMS[k]) {
document.cookie = `${k}=${UTMS[k]}; max-age=2592000; path=/; SameSite=Lax`
}
}
return next()
})
The cookie persists for 30 days, which is long enough to capture the typical SaaS evaluation cycle. On signup, the cookie values are written to the signup_event row in the database alongside the user ID.
The reporting view is one SQL query:
SELECT utm_source, utm_campaign, COUNT(*) AS signups
FROM signup_event
WHERE created_at > now() - interval '30 days'
GROUP BY utm_source, utm_campaign
ORDER BY signups DESC;
The first time you run this query, you will see something you did not expect. For TanStack Ship in Q1 2026, the surprise was that utm_source=hackernews was the second-largest signup source behind utm_source=producthunt. I would not have known that without the UTM tracking, because HN comments do not look like referrals in any other signal.
Referral Programs: Turn Users Into Your Sales Team
A referral program is a reward given to an existing customer when they bring in a new customer. The shape is two-sided: the referrer gets $X, the referee gets $Y. The reward is paid in account credit, not cash, so it stays in the ecosystem.
The minimum implementation is a referral code per user, a tracking table, and a webhook from Stripe that fires on successful checkout:
CREATE TABLE referral_credit (
id TEXT PRIMARY KEY,
referrer_user_id TEXT NOT NULL,
referee_user_id TEXT NOT NULL,
reward_cents INTEGER NOT NULL,
status TEXT NOT NULL, -- 'pending' | 'applied' | 'expired'
stripe_event_id TEXT NOT NULL UNIQUE,
created_at TEXT NOT NULL DEFAULT (datetime('now'))
);
The stripe_event_id UNIQUE constraint makes the reward idempotent — Stripe will retry the webhook on 5xx, and the second insert fails harmlessly. The status transitions to applied when the referee's subscription clears the refund window (14 days for TanStack Ship).
The economics that matter: the reward must be less than the customer's LTV, otherwise you are paying to acquire unprofitable users. For TanStack Ship at a $29/month starting plan with a 14-month average lifetime, the LTV is roughly $400. A $20 reward to each side ($40 total) leaves $360 of margin. The referral program is profitable when the referee's retention matches the average.
What I would not build: a multi-tier referral program with "silver" and "gold" levels. The complexity kills it. One tier, one reward, one webhook. Ship that first.
Content Marketing: Write Once, Acquire Forever
The content lever is the slowest and the highest-ROI. A blog post that ranks for a long-tail keyword brings signups for years. The cost is the hours to write it. The leverage is that each post compounds.
The cadence that works for a solo founder: one post per week, 1,500-2,000 words, targeting one specific keyword cluster. The post should answer one specific question better than any existing result. The internal links should connect it to the rest of the site. The CTA should be specific to the post's audience, not a generic "sign up."
For TanStack Ship, the content that worked best was technical deep-dives — cloudflare-d1-query-optimization-techniques, cloudflare-workers-cron-triggers-scheduled-tasks, tanstack-router-type-safe-routing. These rank for terms that solo developers search when they are about to ship. The posts convert at 4-6% from organic search.
What I would not do: write about "how to start a SaaS" or "top 10 SaaS tools." The keyword volume is high but the intent is low. The reader is browsing, not building. The conversion rate is below 0.5%.
The Keyword Cluster Pattern
The posts that worked best all targeted a single keyword cluster. A cluster is the parent term plus long-tail variants — "cloudflare d1" as the parent and "cloudflare d1 query optimization," "cloudflare d1 backup" as children. One pillar post targets the parent; supporting posts target the children; internal links connect them. The pillar ranks for the high-volume head term; the supporting posts rank for the long-tail variants and feed authority back.
The cadence that compounds: one pillar per quarter, four supporting per month. The supporting posts are 1,200-1,500 words each — shorter than the pillar but covering one specific question. Every supporting post links to the pillar, the pillar links to every supporting post, and the supporting posts cross-link where topics overlap.
I did not know this when I started TanStack Ship's blog. The first six months were single posts targeting single keywords; the rankings were unstable. The cluster pattern stabilized them.
Community Building: Discord, Reddit, and Hacker News
Community is the second-highest-leverage lever after content, and the one most often done wrong. The wrong shape is "build a Discord and invite everyone." The right shape is "find the existing community where your buyers already are, and contribute there first."
For TanStack Ship, the relevant communities are r/SaaS, r/CloudFlare, r/TanStack, the Cloudflare Discord, and Hacker News. I spend 30 minutes a day in one of these, answering questions that are within my competence. The signal is not the immediate upvote — it is the person who clicks my username, sees the bio link, and signs up three days later.
Discord, Reddit, and HN each have different norms:
- Discord — sustained presence, helpful answers, no marketing speak. The owner of a community Discord who promotes their product gets muted. The helpful non-owner who mentions their product in context gets listened to.
- Reddit — substantive comments, link to your own content only when directly asked. Self-promotion rules are enforced; violations get you banned.
- Hacker News — thoughtful top-level comments on relevant stories, occasional Show HN launches. Commenters who mention their own product without context get downvoted.
The cost is real: ~2 hours per day, ongoing, with no immediate payoff. The return is the same customers you would have paid $40 each to acquire, except they arrive pre-sold because they have already read your answers for three months.
Email Marketing: Automated Nurture Sequences
Email is the conversion lever. The visitor reads your blog post, likes it, leaves. Two days later, an email brings them back. The nurture sequence is the difference between "I read one post" and "I signed up."
The minimum sequence is three emails:
Day 0: Welcome. Link to the best 3 blog posts. One CTA: start free trial.
Day 3: Case study. Real customer, real metric, real outcome. CTA: see the dashboard.
Day 7: Objection handling. Address the top 3 reasons people don't sign up.
After Day 7, the sequence branches based on behavior: did they start a trial? Did they hit a specific page? The branching is where the conversion lift happens, but it is also where most solo founders over-invest. Three emails beats zero. Ten emails with branching beats three. But the marginal lift from ten to twenty is small.
I use Loops for transactional and Resend for broadcast. The combo costs $20/month combined. Both have free tiers that cover the first 100 subscribers.
Paid Acquisition: When and How to Spend
Do not pay for ads until month 4. Until then, the organic levers above have higher ROI and produce more durable learnings. The first paid dollar should go to retargeting — people who visited your site but did not sign up. The second paid dollar should go to lookalike audiences of your existing customers. The third paid dollar should go to a single keyword on Google Ads with a clear commercial intent.
The shape of paid acquisition that does not work at 0-100 customers: brand awareness, display ads, broad social campaigns. The CPM is too high and the attribution is too weak to learn anything useful. Wait until you have 50+ paying customers and a clear ICP before scaling paid.
When I did finally turn on paid for TanStack Ship, it was a single Google Ads campaign for the keyword "tanstack starter" and a single Reddit retargeting campaign for visitors who hit /pricing. The combined spend was $400/month. The ROAS was 3.2x at month 6. That is the upper bound of what a solo founder should be spending on paid before they have a marketing hire.
Measurement: North Star Metrics and Growth Loops
The measurement that matters is one number: weekly new paying customers. Everything else is a leading indicator.
The secondary metrics that matter:
- Activation rate — share of signups who complete the setup flow within 24 hours. For TanStack Ship, this is "created a Cloudflare Worker and deployed the starter template."
- Time-to-value — median time from signup to first successful API call. For TanStack Ship, ~8 minutes.
- Referral share — share of new customers who arrived via a referral code. Target: 20-30% by month 6.
- Content-attributed signups — share of signups with
utm_sourcematching a content piece. Target: 40-50% by month 6.
The growth loop is the cycle: content → signups → customers → referral content → more signups. If the loop is spinning, growth compounds. If any link is broken, growth stalls. The metrics above tell you which link is broken.
How to Choose Between Levers
If you have 60 minutes and 0 paying customers, spend them in this order:
- UTM middleware (4 hours, one-time) — never skip this.
- Welcome email sequence (2 hours, one-time) — catches signups you would have lost.
- One blog post targeting one keyword (4 hours, ongoing) — the highest-leverage hour.
- 30 minutes in one community (daily) — the second-highest leverage.
The remaining levers — referrals, paid, advanced email — come after you have 10+ paying customers and have validated the basics.
What I Would Not Skip on Day One
Three things I almost skipped and am glad I did not:
- UTM middleware before the first growth post. Without it, I would not know which posts worked.
- A
signup_eventtable before the first paying customer. Retrofitting analytics is painful; capturing the first event correctly is free. - A daily 30-minute community block before any "build the brand" effort. The compounding returns on community are larger than any amount of paid spend at small scale.
