10,000+ users in 24 hours & YC funding a few days later: lessons learnt

Great PR for Heroku and Nezumi:<p><i>If we were on a cheap VPS, we would have crumbled to pieces like Cobb's limbo in Inception. As we were on Heroku, we could simply increase the number of dynos. I still vividly remember when our traffic hit. I was away from my desk, so I reached for my iPhone and dialed us up to 20 dynos using Nezumi. A few seconds later, we had scaled.</i>

One thing I've been wondering - how does rapportive remove the Google Adwords in the right sidebar without pissing off Google? This has got to be a violation of their TOS or something isn't it?

Great work guys. Ride the rocket as high as you can!<p>(You're missing an opportunity to funnel people to your site from your blog. You should have a little PR blurb and link at the top of the page)<p>Also... Additional respect that you took the time to send some love to your service and infrastructure providers.

That's not a startup, it's a Gmail feature. Amazes me what gets financing nowadays...

Great write-up. I'd heard of you but couldn't remember what your product was. Have you thought about putting a PR-type blurb at the top of your blog, like "Rapportive shows you everything about your contacts right inside your inbox." with an obvious link to your website?

To the founders: Congrats and thanks for sharing your reflections with us.<p>Is there a Rapportive API in the works?<p>I would love to integrate Rapportive into some apps I'm currently working on instead of plugging into the Gmail sidebar.

I wonder how are they going to make money off this.

How do you justify removing gmail ads and replacing them with your social addon? Isn't google going to be slightly pissed?

I like the idea and love to see it working for a long time, but I totally see GMAIL doing something like this in the future or hopefully buying you out...

I agree with most of this post except that you should build to scale. Scaling isn't what you should be focused on. If you focus on this you will loose sight of the product you should be developing and responding to user feedback.

Right place, right time, good product, and a little luck. That's awesome to read, hear, and see. I wish them the best and hope all my endeavors bear such tail winds.

Congrats on your success! You know you have a good product when people want it before it's even officially public.

Congrats to the founders. Great insight on really how Heroku can be beneficial.

Quite nice. I would be interested in seeing this in Thunderbird, though.
