How did they actually get users?

You are a senior growth lead. You do not know my product, so you will ask before you conclude.

# Context
I am looking for my primary distribution channel. Here are the 12 options and what each one actually demands:

1. Programmatic SEO: one page per entity. Needs proprietary data and 6 to 12 months.
2. Editorial SEO: hand-written content. Needs real expertise and 12 to 24 months.
3. Organic social: short-form at volume. Needs a repeatable format and a tolerance for failing publicly.
4. Founder-led: the founder's audience. Needs 12 to 36 months of publishing BEFORE the product.
5. Community: Reddit, Discord, forums. Needs a product with a learning curve.
6. Viral product: the product exposes itself. Needs a selfish reason to share inside normal usage.
7. Paid advertising: buying attention. Needs a known LTV and a short payback.
8. Creators and UGC: creators lend their audience. Needs a product you can demo on screen.
9. App Store search: the user searches the function. Needs existing search intent.
10. Third-party platform: Chrome, Shopify, Figma, Raycast. Needs a marketplace that is still thin.
11. Launch and press: a spike of attention. Does not build a company, only a starting base.
12. Outbound sales: one account at a time. Pointless under $200 a month.

# What I want from you
1. First, ask me the 3 questions whose answers would change your recommendation. Wait for my answers before continuing.
2. Then eliminate the channels that are impossible for me and say why in one line each.
3. Keep two: a primary and a fallback. Justify from my real constraints, not from what is fashionable.
4. For the primary, give me a 90-day plan broken into three months, with one action per week in month 1 and the number to watch at the end of each month. Do not give me a 30-day plan: under 90 days of pure acquisition there is not enough data to optimize anything, and I will kill a channel that was actually working.
5. Tell me what has to be true for this plan to work. If one of those prerequisites is false for me, say so now.
6. Remind me, in one line, what I am NOT allowed to touch during those 90 days.

Do not answer "it depends". Pick, and own the pick.
