Product development is a complex interative process involving multiple
disciplines and a variety of tools
Collaboration in hardware product development is a nightmare - existing
tools are siloed, discipline specific, and don’t play well together.
Even simple hardware issues require coordination between multiple
people working in different environments

Integration improves customer experience and speeds adoption
Simpler Adoption. By integrating into CAD we
show up where engineers already work. To them
we’re not a new tool, but rather a new set of
capabilities that make their work easier.
Customer Experience. Five Flute wins over general
purpose tools by connecting directly to the
engineering assets that hardware teams develop,
providing a rich visual context for team
communication and more efficient issue tracking
workflows for all collaborators.
Stickiness and Defensibility. Our long term
advantage is cemented by integrating across the
entire product development tool chain.
Product Led. Transparent pricing, easy onboarding,
great help docs = short time to value. Our core
functionality is team communication so every
message is an opportunity to convert collaborators
to account holders.
Mechanical CAD > ECAD > ID > PLM
WHY WE WIN
There are examples of the integration-first strategy paying off massively.

Engineers

Engineers do daily design work in CAD packages like
SolidWorks. Beyond ME’s, Five Flute is valuable for cross-
functional teams. Electrical engineers use Five Flute to resolve
fit issues with PCBs and industrial designers use Five Flute to
collaborate with ME’s.

Technicians & Support Staff

Technicians support design work in the build and test phases
and report & resolve issues in actual physical hardware.

Engineering Managers

Engineering managers oversee teams of 3-10 engineers and
are involved in making daily design decisions. They use Five
Flute to understand the status of the project and to manage
engineer workloads.

VP of Engineering

The VPE oversees all design work done by the company. Their
primary use case for Five Flute is to get a big-picture
understanding of product development status.
