Problems the Self-Tracking Industry must
overcome (that Notch aims to solve)
Losing Users’ Attention
Maintaining long term engagement (& staying top of mind)
Ineffective Communication of Data
Finding context & shedding our (data) geeky past.
Supporting Behavior Change
Enabling, targeting, & measuring the BCT du jour.
Moving past early adopters.

and your ‘result stories’, I

Now, I want to view all of my

in interesting new ways”

Why choose ?
RunKeeper is one of the top self-tracking
apps in the world. Over 20 million
runners, walkers, hikers, and cyclists log
into RunKeeper to track their activity.
Whenever a RunKeeper user breaks a
personal record (e.g. fastest mile time),
RunKeeper sends them an email
By replacing these text emails with an
Achievement Visualization, Notch helped
RunKeeper increase email CTR by 200%,
achieved 10% share rates to Facebook &
Twitter, and, for 7 consecutive days, 0%
Notch.me is the ‘petri dish’ for
creating engaging visualizations.

Purpose: To experiment with small, scalable
emotional triggers, making users more receptive
to positive behavior change.
What: Allows users to connect 4 different external
sources (Fitbit, RunKeeper, BodyMedia, Jawbone
UP). Data is pulled from these devices, cached
locally, then used to generate dynamic,
personalized data visualizations.
Sharing/Snapshot system allows users to share
visualizations (e.g. to Facebook/Twitter) for a
single point in time.
Visualizations: 8 visualizations published to date
(out of 100s of concepts). Visualization production
time reduced from 3 months to ~2 weeks. All
visualizations built for both Mobile and Desktop.

various research projects, ranging from developing
a 3d interface for computerized microscopes, to
applying artiﬁcial intelligence algorithms to games
(Hierarchical Task Networks and Temporal
In 2008, Eli founded Unblab, which provided a
machine learning service for identifying personally
important email messages (like Gmail’s Priority
Inbox). Over the 2.5 years working on Unblab, Eli
raised seed ﬁnancing from 5 local angel investors,
invented/implemented its email classiﬁcation
system (based on 60+ signals of importance), and,
ultimately sold the company to AOL in 2010.
After Unblab was acquired, Eli spent a year as a
product manger at AOL, where he lead a small
team in creating a highly differentiated email client
called Project Oh.

and his many hats.
Eli’s work on Notch includes:
- concepts, architecture, copywriting, & art
direction for all visualizations;
- sourced & directed an international team of
artists, illustrators, and visual-designers;
- developed collaborative processes to reliably
combine world-class art and aesthetics (right brain)
with algorithmically generated data visualizations
(left brain). production time from 3mo -> 10 days.
- developed relationships across the mHealth
industry, leading to 4 major Notch.me integrations
- direct integration with RunKeeper, resulting in
100s of thousands of unique visitors to Notch.me
- many, many partner pitches, resulting in a deep
sense of humility (& appreciation for wide funnels..)
- wrote all code for Notch.me
