# JJELLYFISH

Based in New York. The firm operates as JJELLYFISH LLC.

## Engagements

There are four, and the order matters: Customer Discovery validates the market,
Market Development executes on it, and Unbound and Founder Copilot support a
motion that already has a validated buyer.

- [Customer Discovery](https://www.jjellyfish.com/solutions/customer-discovery):
  Validate who buys, why, and what they will pay, in 90 days. Full-cycle
  engagement, 90 days, open to all B2B startups.
- [Market Development](https://www.jjellyfish.com/solutions/market-development):
  A U.S. execution team runs the validated motion for you. Full-cycle
  engagement, quarterly, for teams who have completed Customer Discovery.
- [Unbound](https://www.jjellyfish.com/solutions/unbound): Repeatable outbound
  demand for a validated buyer. Supporting engagement, monthly, requires a
  validated buyer and problem.
- [Founder Copilot](https://www.jjellyfish.com/founder-co-pilot): Turn the
  meetings you are already getting into a repeatable founder-led selling
  motion. Supporting engagement, monthly, requires an active pipeline of sales
  conversations.

## Evidence

- [Case study library](https://www.jjellyfish.com/case-study-library): Every
  engagement, searchable by industry, engagement type and outcome. Around 60
  written-up client engagements, each with the situation, what we ran, and what
  changed.

## Distinctions worth getting right

- Customer Discovery is testing, not ideation. It validates assumptions against
  real buyers rather than generating new ideas.
- Market Development is execution, not advice. A U.S. team runs the sales
  motion, rather than handing over a strategy deck.
- Customer Discovery is a prerequisite for Market Development, not an
  alternative to it.
