90-Day Sprint Plans by Stage

Core Rule

90 days is enough to prove anything. If you can't show measurable progress in 12 weeks, the problem isn't time — it's focus.

Stage 0: Idea — 90 Days to Validated Problem

Goal: Go from "I have an idea" to "I have evidence that real people will pay for this."

Weeks 1-2: Problem Interviews

Deliverables:

• List of 50 target interview candidates (name, contact, why they fit)
• 20 completed problem interviews (minimum)
• Interview notes document with verbatim quotes
• Top 3 pain points ranked by frequency and intensity

Daily actions:

• Send 5 outreach messages per day requesting interviews
• Conduct 2 interviews per day (20-minute calls)
• Log every conversation same-day — don't let memory fade

Interview script:

1. "Tell me about the last time you dealt with [problem area]."
2. "What did you do about it?"
3. "What was the hardest part?"
4. "If you could wave a magic wand, what would change?"
5. "Have you looked for solutions? What did you find?"
6. "How much time/money does this cost you today?"

Week 2 checkpoint: If you cannot find 20 people to talk to, the market may be too small or the problem too niche. Pivot the audience, not the solution.

Weeks 3-4: Solution Hypothesis + Landing Page

Deliverables:

• One-page solution brief (problem, solution, who it's for, how it works)
• Live landing page with clear value proposition
• Email capture form connected to a mailing list
• 3 distinct positioning statements to A/B test

Week 3 tasks:

• Write the solution brief based on interview data
• Register domain name
• Build landing page (Carrd, Framer, or simple HTML — no code needed)
• Write 3 headline variations for testing

Week 4 tasks:

• Launch landing page
• Share with 10 interviewees for feedback
• Set up basic analytics (page views, signup rate)
• Revise copy based on which headline converts best

Landing page must include:

- Headline: [Specific outcome] for [specific audience]
- Subhead: 1 sentence on how it works
- 3 bullet points on key benefits
- Email signup: "Join the waitlist" or "Get early access"
- Social proof placeholder (interview quotes work here)

Week 4 checkpoint: If zero interviewees say "I'd use this," revisit your solution hypothesis before moving on.

Weeks 5-6: Waitlist Building

Target: 100 signups

Deliverables:

• 100+ email signups on waitlist
• Documented acquisition channels (which worked, which didn't)
• Cost-per-signup data if running paid experiments
• Waitlist welcome email sequence (3 emails)

Week 5 tasks:

• Post in 5 relevant communities (Reddit, LinkedIn groups, Slack communities, forums)
• Direct-message 20 people from your interview list
• Ask every signup to share with one friend
• Write 3-email welcome sequence

Week 6 tasks:

• Run a small paid test ($50-100 on Facebook or Google) to test cold demand
• Publish one piece of content about the problem (blog post, tweet thread, LinkedIn post)
• Reach out to 5 potential distribution partners or influencers
• Compile channel performance data

Welcome email sequence:

Email 1 (immediate): "You're on the list. Here's what we're building and why."
Email 2 (day 3): "The problem we're solving — and what we've learned so far."
Email 3 (day 7): "Want to help shape this? Reply with your biggest challenge."

Week 6 checkpoint: If you cannot reach 100 signups across all channels, demand signal is weak. Either the problem isn't painful enough or the positioning is off. Go back to interviews.

Weeks 7-8: Prototype / Mockup Testing

Deliverables:

• Clickable prototype or detailed mockup (Figma, slides, or paper)
• 10 prototype walkthroughs with waitlist members
• Feedback log with feature priorities
• Updated solution spec based on feedback

Week 7 tasks:

• Build clickable prototype (Figma, InVision, or Google Slides with linked screens)
• Schedule 10 walkthrough sessions with waitlist members
• Prepare a standard walkthrough script

Week 8 tasks:

• Conduct all 10 walkthroughs
• Score each feature: Must-have / Nice-to-have / Don't care
• Identify the one feature that gets the most emotional response
• Update your spec: build the must-haves only

Walkthrough script:

1. "I'm going to show you something early. Be brutally honest."
2. Walk through the core flow — no more than 5 screens.
3. "What would you expect to happen next?"
4. "What's confusing?"
5. "Would you pay for this? How much?"
6. "What's missing that would make this a must-have?"

Week 8 checkpoint: If nobody would pay, you have a vitamin, not a painkiller. Narrow the problem or change the audience.

Weeks 9-10: Pre-sell or LOI Collection

Target: 5 letters of intent or 3 pre-sales

Deliverables:

• 5 signed letters of intent (LOIs), OR
• 3 pre-sale payments collected, OR
• 10 verbal commitments with follow-up dates
• Pricing validated at a specific number

Week 9 tasks:

• Draft LOI template (one paragraph, non-binding, states intent to purchase at $X)
• Email top 20 waitlist members with pre-sale offer
• Offer early-bird pricing: 30-50% discount for committing now
• Set up payment collection (Stripe link, invoice, or simple PayPal)

Week 10 tasks:

• Follow up with every lead who didn't respond
• Conduct 5 closing conversations (phone or video, not email)
• Collect signed LOIs or payments
• Document objections and reasons for "no"

LOI template:

LETTER OF INTENT

I, [NAME], [TITLE] at [COMPANY], confirm interest in [PRODUCT NAME]
for the purpose of [USE CASE].

I intend to purchase at a price point of approximately $[AMOUNT]/[PERIOD]
upon product availability.

This letter is non-binding and represents intent, not commitment.

Signed: _______________
Date: _______________

Week 10 checkpoint: If you cannot get a single pre-sale or LOI, the willingness to pay is not there. Re-examine pricing, audience, or the entire concept.

Weeks 11-12: Go / No-Go Decision

Deliverables:

• Decision document: GO or NO-GO with supporting data
• If GO: 90-day build plan with launch date
• If NO-GO: Pivot hypothesis or shutdown plan
• Investor-ready one-pager (if GO)

Week 11 tasks:

• Compile all data: interviews, signups, prototype feedback, pre-sales
• Score against go/no-go criteria (see below)
• Draft decision document
• Share with 2-3 trusted advisors for gut check

Week 12 tasks:

• Make the call
• If GO: Write the Stage 1 sprint plan, start building
• If NO-GO: Send honest update to waitlist, document learnings, decide on pivot or stop
• Either way: publish a brief retrospective for yourself

Go / No-Go Scorecard:

3+ Green = GO. 3+ Red = NO-GO. Everything else = revisit your weakest area for 2 more weeks.

Stage 1: Pre-Revenue — 90 Days to First 10 Customers

Goal: Go from "validated idea" to "10 paying customers acquired through a repeatable motion."

Weeks 1-2: Direct Outreach Blitz

Deliverables:

• 100 personalized outreach messages sent
• 15+ conversations booked
• CRM spreadsheet tracking every lead
• Outreach templates that get >10% response rate

Daily actions:

• Log every interaction in your CRM spreadsheet

Weeks 3-4: Manual Onboarding of First 3

Deliverables:

• 3 paying customers onboarded (even at a discount)
• Onboarding checklist documented
• Customer feedback from each (what worked, what didn't)
• Refined pitch based on what actually closed

Tactics:

• Offer concierge onboarding — do it for them if needed
• Price at 50% of target to reduce friction
• Get on a call with every customer during their first week
• Ask: "What almost stopped you from buying?"

Weeks 5-6: Pricing Experiments

Deliverables:

• 3 pricing variations tested with real prospects
• Data on conversion rate by price point
• Final pricing decision for next 90 days
• Updated landing page with pricing

Test structure:

Group A (10 prospects): Original price
Group B (10 prospects): 20% higher
Group C (10 prospects): Different model (annual vs monthly, per-seat vs flat)
Track: response rate, close rate, objections

Weeks 7-8: Referral + Second Channel

Deliverables:

• Referral ask sent to all existing customers
• 2 new customers from referrals
• One new acquisition channel tested (content, partnerships, community)
• Channel performance comparison document

Referral script:

"Hey [Name], glad things are going well. Quick ask:
Do you know 1-2 people dealing with [problem]?
Happy to give them [incentive — discount, free month, etc.]
and you get [referral reward] if they sign up."

Weeks 9-10: Process Lock-In

Deliverables:

• Sales process documented end-to-end (outreach to close)

Weeks 11-12: Push to 10 and Retrospective

Deliverables:

• 10 paying customers
• Customer acquisition cost (CAC) calculated
• Monthly recurring revenue (MRR) documented
• Stage 1 retrospective: what worked, what didn't, what to double down on

Week 12 checkpoint: If you have 10 customers, you have a business. If you have 5-9, extend this stage. Under 5 after 12 weeks means your channel, pricing, or product needs a rethink.

Stage 2: Early Revenue — 90 Days to Repeatable Sales

Goal: Go from "10 customers I personally sold" to "a sales process that someone else could run."

Weeks 1-2: Process Documentation

Deliverables:

• Sales playbook: step-by-step from lead to close

4. Partnerships (referral deals, integrations)
5. Community (events, forums, groups)

Weeks 5-6: Hiring First Help

Deliverables:

• Role description for first hire (sales, ops, or support)
• 3 candidates interviewed
• First contractor or part-time hire started
• Delegation checklist: what they own vs. what you own

Hire decision framework:

If bottleneck = finding leads → hire sales/marketing help
If bottleneck = delivering the product → hire ops/technical help
If bottleneck = keeping customers happy → hire support
If bottleneck = everything → hire a generalist VA first

Weeks 7-8: Metrics Dashboard

Deliverables:

• Dashboard tracking: MRR, churn, CAC, LTV, pipeline
• Weekly review ritual established (30 min every Friday)
• Targets set for each metric for the next 90 days
• Alerts for churn risk (customers going quiet)

Minimum metrics to track: | Metric | How to Calculate | Target | |--------|-----------------|--------| | MRR | Sum of all monthly payments | Growing 15%+ month-over-month | | Churn | Customers lost / customers at start of month | Under 5% monthly | | CAC | Total sales spend / new customers | Under 1/3 of first-year revenue per customer | | LTV | Average revenue per customer x average lifespan | 3x CAC minimum | | Pipeline | Number of active conversations | 3x target closes |

Weeks 9-10: Pricing Optimization

Deliverables:

• Annual pricing option introduced (15-20% discount for commitment)
• Upsell or add-on identified and offered to existing customers
• Net revenue retention measured (are customers spending more over time?)
