A repeatable system for expanding from one product to many. Structurally, new product bets are pulled out of the mature-product org into a separate expansion org so their roadmaps aren't trumped by the 'gravitational force' of the core. Each bet is treated like an angel-invested seed company with a dedicated cross-functional squad, reviewed every quarter or half for continued investment. New products are selected for adjacency, de-risking signal, and distribution advantage — then given away free before monetizing complexity.

Origin

Rohini Pandhi's approach leading Mercury's product expansion org; informed by Block/Square's multi-product success and Gokul/Jack's 'build products people love, revenue follows' ethos.

Core principles

  • 01Give new fires air to grow — keep seedlings organizationally separate from mature products so their roadmaps aren't crowded out
  • 02Treat each new product as a seed-stage company: dedicated squad, angel-investor mindset, periodic reinvestment decisions
  • 03Expand into adjacencies just beyond the core — a new product line for an adjacent segment, not just another feature
  • 04Prefer bets you can de-risk with existing traction and where you hold a distribution advantage
  • 05Build products people love and let revenue be the byproduct; don't revenue-optimize at launch
  • 06Anchor customer obsession back to the business — a want that can't sustain a viable business isn't a product

How to run it

  1. 1

    Separate seedlings into their own org

    Create a distinct expansion org so new product areas aren't structurally close to core banking/payments, whose maintenance and higher-impact work would otherwise always trump the seedling's roadmap.

    Pro tip Run the new teams on a different cadence — two-week sprints and weekly check-ins instead of the core's monthly cycles — to stay nimble and learn-iterate-repeat.

    Watch out Keeping new bets inside the mature org lets the 'gravitational force' of the mature product starve them of prioritization and space.

  2. 2

    Staff each bet like a seed company

    Give it a full cross-functional squad (eng, design, product, data science), borrowing central teams (CS, risk, ops) unless dedicated support is needed. Size to the opportunity — a whole new personal-banking market got ~3x the engineers of an invoicing bet built atop existing banking.

    Pro tip Give teams 'just enough' resources but make them stretch.

    Watch out Trying too many things at once and understaffing each is a classic misstep — the seedling never gets enough hands to survive.

  3. 3

    Select products by adjacency, de-risk signal, and distribution

    Look for an adjacent customer segment wanting a fuller product (not a mere feature), evidence of existing demand you can point to, and a distribution advantage where you can reach users inside your current product without a full go-to-market.

    Pro tip Surface the new product inside the natural flow of the existing one (e.g. highlight Bill Pay when a user sends a complex vendor payment).

  4. 4

    Reinvest on a quarterly/half-yearly review

    Every quarter or half, decide whether to keep investing. Set goals and financial projections, but weight learnings heavily like an angel investment — if a goal is missed, ask what key learning still points toward success in the next six months. There's no forced return to the core until the line becomes a 'Series C' business in its own right.

    Watch out Don't kill a bet purely for missing a number early — but do demand a clear learning that keeps it pointed at success.

  5. 5

    Give it away free, then monetize complexity

    After launch, don't jump to revenue optimization. Give the second/third product away free to drive usage, engagement and retention; keep core money movement and basic functionality always free. Charge only when the customer needs real added complexity, and only for the ICP at the complex end of the scale.

    Pro tip Run a real willingness-to-pay process and put a genuine price in front of the ICP — a price is itself a test of product value and fit.

    Watch out Slapping a paywall on at launch ('now you have to pay us') breaks trust; monetize when the customer journey reaches genuine complexity (often 6–18 months into a business).

In the wild

Mercury's 2024 product wave

Mercury launched personal banking (April), then a software suite atop business banking — Bill Pay (May), invoicing (August), spend controls/management and employee reimbursements (October). Invoicing was de-risked via an existing 'payment requests' feature (send a URL to get paid) that already had traction and an installed base to distribute to, avoiding a full go-to-market.

Each subsequent launch took less time than the previous from concept to launch, and all showed strong positive signal.

Common mistakes

Keeping new bets too close to the core org

Structural proximity lets the mature product's prioritization and maintenance work constantly trump the seedling's roadmap, starving it of space to grow.

Trying too many things at once and understaffing

Spreading thin means no seedling gets enough people to be nurtured to survival.

Paywalling a new product at launch

Charging immediately, before proving customers love and rely on it, kills adoption and trust versus free-first then monetizing complexity.

Is it for you?

Best for

Product leaders and founders at a successful single-product company attempting to expand into new product lines

Not ideal for

Companies still searching for fit on their first product, who lack a core to spin adjacencies off of

From the transcript

having um new product areas, new seedlings being too close within the like true org structure to the core banking or payments for mature products…

46:30

when you have this small little uh fire, you want to give it air in order for it to truly blossom to a flame

47:30

We're we're thinking of these company like these are small seed stage companies and every quarter every half year we look at them as like…

48:00

each subsequent launch that we just described took less time than the previous from concept to launch

46:00

we want is to give away that the second product, the third product for free
