How David Park grew an AI SaaS to $10M ARR with short-form video

Executive overview

Most founders either ignore short-form video or treat it as a branding exercise. David Park used it as his primary acquisition channel, taking Jenny AI from zero to $10M ARR and 5 million users in two years.

The playbook has three phases: gather ingredients (audience and content research), explore (test hypotheses across creators, hooks, and accounts), and exploit (turn winning content into evergreen series and multi-account distribution).

Once you find one viral video format, you can milk it for hundreds of millions of views across multiple accounts and languages — without restarting from scratch.

The three growth pillars

• Distribution: getting users to discover your product via video
• Conversion: turning viewers into paying customers
• Retention: keeping users after they've paid
• This playbook covers distribution only — specifically short-form video

Gathering ingredients: audience and content research

• Survey your users; ask for their Instagram handles and observe what they watch
• Use the platform algorithm to surface more influencers: check "suggest similar accounts" and hashtag pages
• Build a dedicated Instagram or TikTok account purely to receive algorithm recommendations — treat it as a lead list
• Look at competitor social accounts; if their angle is working, use it as a starting point
• Scroll your research account until something naturally stops you — analyse why, then build on that hook

Finding and evaluating influencers

• Prioritise ceiling over floor: one video with 1–2M views matters more than consistently hitting 10K
• Check whether their sponsored content historically underperforms — if it always flops, move on
• Niche, rising influencers offer better value than large creators with agents who know how to extract maximum fees

Outreach tactics

• Send both email and DM; content creators don't check email daily
• Follow up within a few days — a bump email signals you're serious
• Messages must be tailored but concise: reference a specific video they made, connect its message to your product's mission
• Never mention fundraising round, employee count, or press coverage — influencers don't care
• Expect 50%+ non-response; treat every attempt as compounding practice

Structuring and negotiating deals

• Never pay 100% upfront; split payment so part is tied to conversions, views, or clicks via coupon code or UTM link
• Buy in bundles (e.g. 3 or 10 videos) to lower cost-per-video and build a real relationship
• Start negotiations by bundling every add-on (exclusivity, story, link-in-bio, usage rights) to inflate the headline price, then strip items back to reach your actual needs
• Ask for cross-platform posting (Reels + TikTok + Shorts) for a ~30% premium — it's minimal extra work for the creator and drastically reduces your cost-per-placement
• Evaluate by audience fit and conversion potential, not follower count

UGC creators vs. sponsored influencers

• UGC is more stable: 20–30 posts per month means a few flops don't matter
• Standard rate: ~$2,000/month base plus a conversion or view bonus
• Hiring an existing influencer for UGC: $3,000–$5,000/month — worth it if even a fraction of their audience follows them to the new account
• Always include an incentive bonus; without it, creators default to minimum effort

Posting strategy

• Repost every video on Reels, TikTok, and YouTube Shorts — rewrite the text hook natively on each platform for SEO
• Post at least once a day; treat it as a hypothesis-testing loop
• Track performance in a spreadsheet; cut non-performing content types, double down on what works
• If an account is stuck under 300 views no matter what, create a fresh account with a new SIM card

Defining virality

• Views, comments, and shares are proxies — true virality is reaching the specific pocket of users who love your product
• A 10,000-view video that converts and evangelises is worth more than a 1M-view video where the product is a skippable mid-roll

Exploiting a viral video: the series model

• Once a format works, turn it into a series: repost the same video with minimal variations (swap the opening scenario, keep the second half identical)
• Jenny AI's "POV: you have a paper due" series ran 2x per week for six months and drove hundreds of millions of views and over $500K in revenue
• Audiences tolerate — and enjoy — repetition; you bypass the entire testing loop on every subsequent post

Scaling with multiple accounts and markets

• Clone the winning series across multiple branded accounts (e.g. Jenny AI USA, Jenny AI Australia, Jenny AI Germany)
• Accounts with 48 followers can outperform your main account with 50K followers when posting identical content — the algorithm doesn't care about follower count
• Translate the series into other languages; a strong format is culture-agnostic
• Extend a fading series by paying meme/aggregate pages ($50–$100 per post) to repost it to large audiences
• When a series is fully played out, restart at step one

Mindset for winning

• Influencer marketing rewards extra effort and creativity — exactly where capital-constrained founders can compete
• First emails will be cringe; first partnership will probably lose money — skills compound faster than costs
• One successful influencer partnership can offset losses from the previous ten
• Give creators creative latitude; organic-feeling content converts far better than scripted ad reads
