From Idea to Launch: Your Startup's Digital Checklist

Launch week failures cluster predictably: email in spam, analytics blind, domain typo-squat, payment webhook misconfigured. This checklist orders tasks by failure cost—what breaks trust or revenue if skipped—not by blog convention.

Receipt #1: Why sequence matters

Stripe Atlas and YC launch guides converge on one pattern: identity infrastructure before marketing spend. NameMesh data shows 31% of 2025 YC companies on .ai—domain + email + analytics must match that TLD choice on day one, or you leak traffic to .com squats (GrowthBadger: users guess .com 3.8× more when memory fails).

Atom 2024: 77% of consumers say domain affects brand trust; 78% distrust get/try prefixes. Launching on TryYourBrand.ai without owning YourBrand.com is a Day-1 trust leak, not a post-PMF fix.

Phase 0: Identity stack (T−14 to T−7 days)

1. Domain acquisition—not registration theater

Do:

• Register primary + defensive (.com if on .ai, common typos, .net if budget allows)
• 5-year registration + auto-renew + registrar lock — expiration outages kill more startups than bad logos
• WHOIS/RDAP accurate per ICANN Registration Data Policy (effective Aug 21, 2025); enable privacy where permitted
• Run USPTO/EUIPO pre-screen before printing business cards

Don't:

• Launch on @gmail.com or registrar parking pages
• Use hyphens/numbers (Atom: 35%/54% trust penalties)

Receipt: Identity Digital — 88% exact-match on non-traditional TLDs for YC/Techstars when .com depleted.

2. Professional email + deliverability

Do:

• Google Workspace / Microsoft 365 / Zoho on custom domain
• Create hello@, founder@, support@ minimum
• Configure SPF, DKIM, DMARC before sending launch email — Google/Yahoo 2024 bulk sender requirements make this mandatory for inbox placement
• Set DMARC to p=none initially, monitor reports, tighten to quarantine/reject

Failure cost: Launch announcement in spam = zero Day-1 conversion.

3. Social handle lock

Reserve consistent handle on LinkedIn, X, Product Hunt, GitHub org. Namechk batch check. Mismatch between @getbrand and brand.com triggers Atom's 77% cross-extension trust damage finding.

Phase 1: Measurement & surface (T−7 to T−3 days)

4. Analytics before traffic

Do:

• GA4 property + web data stream live on staging and production
• Define 3 conversion events: signup, demo request, payment intent
• Microsoft Clarity or Hotjar for qualitative friction (free tiers sufficient)
• UTM convention documented (utm_source, utm_medium, utm_campaign) before any launch post

Receipt: You cannot optimize launch week without baseline—founders who add GA4 on Day 3 lose 72 hours of channel attribution.

5. Launch page / MVP site

Do:

• Single canonical URL (apex OR www—301 the other)
• HTTPS only; HSTS after verification
• Mobile LCP <2.5s on 4G (Core Web Vitals threshold)
• Clear headline + one CTA + email capture or waitlist
• Legal minimum: Privacy Policy, Terms (required for Stripe, App Store, GDPR)

Don't: Ship Coming Soon on a subdomain while app lives elsewhere—splits SEO entity signals.

6. Support surface

• FAQ with top 10 objections (pricing, data, onboarding)
• Crisp/Intercom free tier OR dedicated support@ with <24h SLA committed internally
• Status page (Better Stack free tier) if uptime matters to B2B buyers

---

Phase 2: Money & compliance (T−3 to T−0)

7. Payment path tested end-to-end

Do:

• Stripe test mode → live mode checklist complete
• Real card purchase/refund cycle
• Webhook endpoints verified (invoice.paid, customer.subscription.updated)
• Tax/VAT configuration if EU/UK customers

Failure cost: Checkout error on launch day = viral negative social proof.

8. Onboarding dry run

• 5 strangers complete signup without verbal instructions — record hesitations
• Mobile-first: >50% of B2B SaaS first visits are mobile (industry median; test on real devices)
• Time-to-value under 5 minutes for self-serve products

9. Domain & DNS health

• whatsmydns.net propagation check after any change
• UptimeRobot/Pingdom on homepage + API health endpoint
• Document DNS in password manager (not founder's inbox only)

---

Phase 3: Launch window (T−0 to T+7)

10. Launch runbook (hour-by-hour)

| Time | Action | Owner | | --- | --- | --- | | T−0 | Flip DNS / remove staging gate | Eng | | T+0 | GA4 real-time verify | Growth | | T+0 | Send launch email (post-SPF/DKIM verify) | Founder | | T+0 | Product Hunt / LinkedIn / X posts with UTM | Marketing | | T+1–7 | Daily analytics review: source, landing, conversion | Growth | | T+1–7 | Respond all support <24h | Support |

Crisis card: Site down → rollback DNS; payment fail → Stripe dashboard + status page update template pre-written.

11. Post-launch iteration loop

• Daily during Week 1: traffic source, drop-off step, conversion rate vs hypothesis
• Personal email to first 50 signups (qualitative gold)
• Changelog or #announcements channel for visible iteration

---

China addendum: non-optional extras

Mainland launch requires parallel track:

• ICP备案 before public hosting on mainland servers — 2–4 weeks; domain must match filing entity
• .cn/.com.cn defensive registration before PR cycle
• WeChat Official Account + mini-program paths often decouple from web domain—but 备案 still anchors to a domain string
• Baidu Search Resource Platform verification separate from Google Search Console
• Email deliverability: enterprise providers (Tencent Exmail, NetEase) with MIIT-compliant setup

---

What this checklist deliberately skips

• Logo perfection — ship readable wordmark; iterate post-traction
• Full SEO content program — launch needs indexable homepage + legal pages, not 50 blog posts
• Every TLD variant — defensive .com + primary TLD sufficient at seed stage

---

Bottom line

Digital launch readiness = domain defensibility + email deliverability + measurement live + payment proven. Skip any one and launch week becomes firefighting.

Atom's trust data and GrowthBadger's memory data say the same thing: your domain and email are the product before your product loads.
