How to save 200K in 
development 
Adam Klein
That's me 
Adam Klein 
Co-Founder of 500Tech.com 
@500TechIL
What this is about 
The technical side of "being lean" 
Actual use cases 
Not technology specific
Please 
Don't wait for a "questions?" slide
The advantages of being 
small
Fake features
Fake features - use case 
Community app where users can request 
assistance from each other 
Users define the radius in which they are 
available 
V1 - 100 alpha users - radius feature is fake 
V2 - decided to give up feature altogether 
Save - 5000ILS
Automate later
Automate later - use case 
Use case - @Chicago.com 
Manually setup email & domain forwarding (less than 1 
new user every day) 
Later on - automatic integration 
Domains weren't even being used 
Save - 12,000 ILS
Funnel driven 
development
use case 
Entertainer marketplace 
Complex code for payment flow - user pays, entertainer 
approves, user is charged 
Users were not even getting to the payment page 
After changing the website flow users started doing 
online purchases 
Save - 20,000ILS
Green flow
Green flow - use case 
Same use case 
Alternative solution - refund if entertainer is not 
available 
Save - 20,000ILS
Think out of the box
Control your users
Control your users 
15,000 users accessing streaming videos 
Scaling up the streaming servers is costly 
Solution: send push notifications in 
batches 
Save - 23,000ILS (a year)
Lean != cheap
Use SaaS 
Urban airship, Pusher - don't reinvent the wheel 
Heroku - optimization against increasing dynos 
Choosing a better SaaS over a cheaper one 
Save - 20,000ILS
Hire experts 
Can save days of development in a few minutes 
Learn and become better at what you do 
4 hour * 400ILS < 40 hours * 200ILS 
Save - 25,000ILS
Build to last
Cheap workforce 
Messy code - hard to change 
Voodoo bugs 
Noone actually does complete refactoring 
We received a project and did a complete refactoring 
over time 
Save - 40,000 ILS
Have the next step in mind 
Building a mobile app as well - think about SPA 
Mobile Web - use a responsive library 
Know where you're going to fall on performance 
SaaS costs 
Save - 35,000ILS
