How Mosaic Group grows

9 tactics and 1 figures from 1 interview.

Mosaic Group ran a portfolio of subscription apps, including RoboKiller, and was sold to Bending Spoons. It grew by adding apps in markets big enough for tens of millions in revenue rather than pushing one app past its ceiling, and by managing price, lifetime value and creative across the portfolio.

Mosaic Group's 9 tactics

Mosaic Group · B2C · app portfolio company

Built one of the leading app portfolios; sold to Bending Spoons

Screen each app or category on three lenses: (1) size: the product must plausibly reach tens of millions of dollars in revenue, avoiding a long tail of zombie apps doing a few hundred thousand each; (2) competition: a 'Goldilocks' market where you can take real share, e.g. RoboKiller was the leading independent spam blocker with carriers not invested and no big adjacent entrants; skip VPNs (everyone spends heavily on paid, so unit economics fail) and personal finance/budgeting (banks bid on the same keywords with far higher LTV); (3) existing demand vs. new category: existing demand allows ASO and performance marketing to pay back right away, while a new category means running at a loss to build demand.

Lets new products act on LTV before years of data exist; no numbers

Early in a product's life, run a range of LTV scenarios (e.g. plus or minus 20% in 5% steps), assign probabilities, pick a best estimate and act on it. Re-check every 1-2 months as renewal data comes in, dropping scenarios (six to four to two) until one precise estimate remains, which takes multiple years. At Mosaic's scale an in-house model could predict the next ~20 renewals from the first one or two, since most churn happens in the first renewals.

Conservative at worst; high LTV:CAC shows how much more spend cash could unlock

Always cap LTV at a set number of years (e.g. start at 2 years, extend to 3-4 as the company matures) because you must get paid back and future dollars are worth less. Early-stage: payback period is the primary filter (make money back in month 1 or within 3 months), with LTV:CAC as a secondary check; a high LTV:CAC under a tight payback signals that finding liquidity would unlock growth. Later-stage: manage to an LTV:CAC threshold (e.g. 2-3x) and treat payback (possibly 12+ months) as a sanity check.

Annual-heavy price calls sometimes proved wrong a year later; this guards against it

Annual retention isn't known when a price test ends, so use the monthly plan's retention change as a proxy, or past price rises ('last time I raised annual 10%...'), and trial-to-paid as a leading indicator. Then sensitize: would the winner still win if retention comes in 10%, 20% or 50% worse? If only a ~5% buffer, don't roll out or roll out cautiously; if it survives a 50% hit, ship it. The proxy is weakest when one plan dominates (e.g. a 70/30 annual/monthly split).

More varied creatives, so winning styles became clear; no numbers

Since Google and Meta are black boxes where you only set bid and budget, creative is the main lever. Always keep a share of creatives in each campaign experimental/unproven. Because every designer has a personal style that leads to 5-10% tweaks, rotate creative team members across products every couple of months (within brand guidelines) and occasionally bring in a new designer told to 'go wild', then double down on styles that win.

Guest's answer to the $10-30M ceiling; three $30M apps can beat one $90M app

Accept that most apps cap out when top-3 keyword rankings max out organic and CAC hits the (usually sub-$100) subscriber LTV, after which only single-digit growth comes from optimization. Grow by adding products instead: e.g. three $30M apps rather than one $90M app, with diversification as a bonus. A portfolio with a consolidated tech stack is also what makes a business sellable to private equity.

Guest says slim apps segment users better and can earn more; no numbers

Before building, talk to users about what they want. Then ask whether the idea is a feature or a product: on a 6-inch screen, eight features confuse users, so prefer two or three slim apps with two or three features each and build a net-new product when there is demand. Every feature that does get built must be labeled up front as either an ARPU feature (e.g. an upsell) or a retention/engagement feature, because they are built and marketed differently.

Net LTV wins most of the time across the portfolio, if conversion holds

Across Mosaic apps, price increases lowered retention less than one-to-one: roughly a 10% price rise cost a couple percent of retention, so LTV usually rose if conversion held. Sensitivity differs by product; apps with a thin layer of value have a lower price ceiling than deep-content products like language learning.

Didn't work: few cancel early; most cancel near the renewal reminder

Tested early cancellation (turning off auto-renew) as a predictor of churn for LTV modeling. Trial-to-paid conversion and usage of the one key value action proved better leading indicators.
