How To 3.5x The Reach Of Your Social Media Posts

What if everyone who saw our social media posts also saw targeted ads that followed them around the web and mobile so we maximize our engagement with them? Now we can.

  1. Before posting a link, video or image on your favorite social media site, first convert it into a Fingrprint (takes 10 seconds).
  2. Then go ahead and post the Fingrprint instead of your normal link or video, and when your viewers click or view, they’ll start to see your text and display ads (retargeted ads) across the web and mobile automatically.

You can even tie specific ads to each Fingrprint, so for example if you post something on twitter about an upcoming webinar, your audience will only see ads about the webinar.

Retargeting with display and text ads is incredibly cost effective and has been shown to increase the chances of a consumer or prospect engaging with your company significantly. And now it’s easy schmeasy automatic.

How We Used Retargeting To Sell To C-Level Executives

It was 2015 and I decided to sell the company. To gain interest I had a short list of 50 CEOs I wanted to reach out to. So I wrote a custom, personal email to each one explaining why we were the “best digital health company no one’s heard of.”

We also wrote a script that showed retargeted display ads to the CEOs who opened and read my emails.

More than a few of those CEOs said, “Yeah, I’ve heard of you guys… you’re everywhere.”

Long story short, we sold the company and everyone was happy. But then we got restless and decided to start another project. We thought  –

Why don’t we build a plugin to popular email sequencers like Hubspot, Marketo and Outreach so that everyone in our email lists can be shown targeted display ads, automatically?

Two years and a little over one million dollars later, we built the retargeting tool of our dreams and named it “Fingrprint.” Because I’m told by my Millennial younger colleagues that it’s cooler without the “e.”

Fingrprint can automatically convert the links, documents, videos, and images in your outbound emails into Retargeting Assets (“Fingrprints”), meaning any prospect who interacts with your emails in any way will start to see your targeted ads across mobile and social media.

If you run online ads in addition to your email campaigns, we’re willing to bet that Fingrprint will significantly increase the ROI ratios of your email list, as prospects are far more likely to engage with brands they see across multiple channels.

Fingrprint is enterprise-ready with full reporting, support for teams and fine grain control of each Fingrprint for advanced audience segmentation. We also integrate to Hubspot and Marketo with a four mouse-clicks integration. To eliminate adoption risk, any changes to your emails by Fingrprint are reversible in one click.

We welcome you to try our extensively tested beta version hassle free for 30 days (no sales calls or credit cards required). And for being a Founding User, we’ll provide you a special (and significant) gift as well!

The Stats Behind Fingrprint

best e2b retargeting

In our previous company, with our email automation app we had a 40% email open rate and a 5% click-through rate, mostly to third party news, articles or videos we would send prospects. We thought that was pretty good.

But one day I asked myself, “What about the other 35% who opened our emails? How do we get them further down the funnel?”

A few years later when we decided to start another company we had an idea – Why not build a plugin for email automation apps so that prospects who open your emails automatically start seeing your targeted display ads on Facebook, Google and LinkedIn? We also thought it would be amazing if you could show different ads to different prospects depending on the specific actions they took.

So we finally made it happen. And it’s ridiculously easy to implement and use with Hubspot, Marketo and Outreach. Integration takes 40 seconds. We counted.

Set it, forget it, and watch your email ROI soar.

What Problem For Marketers Does Fingrprint Solve?


Problem: Marketers can’t display ads to most of the subscribers in their email lists, resorting to pay per click bidding wars campaigns and shotgun display ads to fill the chasm between outbound emails and paid inbound traffic.

Solution: Create enterprise software that “fingrprints” prospects when they read emails or documents so that everyone is shown relevant display ads. Then integrate to popular email apps like Hubspot, Marketo and Outreach and allow marketers fined grain control of the prospect’s ad journey with attribution. All with GDPR compliance in mind.

While prospect response rates to emails keep falling, in our last two companies we saw a near 3x increase in response rates when prospects also saw our ads across the web and mobile.

So we created an automated way for marketers and salespeople to do just that.

Fingrprint is a simple way to turn your outbound emails into retargeting assets or “Fingrprints.” Meaning subscribers to your email sequences automatically start to see your highly targeted display ads across mobile and social automatically. This integration to your email sequencer takes about 40 seconds, and any changes can easily be undone so it’s enterprise-safe for managers.

Sales teams and social media agencies can also insert Fingrprinted links, documents and videos into emails, LinkedIn messages, chats, and social media posts. Now (optionally) sales teams and agencies can deliver more value to their activities by automatically connecting display ads with their outbound communications and social media posts. 

You can connect your Facebook, Google or LinkedIn ads account to Fingerprint in 30 seconds and integrate it into Hubspot, Marketo or Outreach in 40 seconds. It’s ridiculously easy and totally automated.

10 Things You Do After Your StartUp is Acquired.

John Sung Kim Net Worth

Selling your baby company is somewhat bittersweet. The money and sense of accomplishment with your team is undeniable, but at the same time it’s odd to go from CEO to employee. Half of my former employees kept asking me, “You ok, JK?” and the other half would give me an occasional look like, “Don’t you dare tell me what to do – you ain’t the boss!”

I came into the office on a Thursday evening – first clue we were acquired – no one was in the office at 6:30pm. I gathered all of my belongings in a CostCo box, turned the lights out and left DoctorBase for the last time.

1. Said goodbye to competitor. Most of my career I’ve heard VCs say, “We like you, but ABC Co. has raised so much money…”

So one of the first things I did was gathered my core team and danced in front of the grave office of my closest competitor who had raised 30x more money (yeah, 30x)! At the time of our exit we had about 2.8x their ARR (Annual Recurring Revenues) with far less churn (percentage of cancelling customers).

It’s why as a hobby micro-angel investor, I never underestimate a roomful of creative people who are die hard about winning.  Having connections is great, but scrappy often wins the day in the long run.

2. Visit Africa. The first trip I made was to go to Morocco to ride camels and haggle for things I didn’t want.

The pictures look great but believe me, the desert is cold, boring and filled with cats. Yes, cats.

John Sung Kim DoctorBase

Which in a way made sense to me because the Sahara looked like a large litter box. However, the people of Morocco were quite lovely and I highly recommend going shopping through the maze like streets of Marrakech – a bucket list worthy experience.

I returned home to San Francisco after ten days in Africa and ate a super burrito every day for a week.  God is great, truly.

3. Buy a bunch of stuff you’ve always wanted (obviously). In my case, motorcycles. I always wanted a different bike for each day of the week, and a house with a garage in San Francisco big enough to house them all. Dream = fulfilled.

And if you really like a particular model, why not buy two?

4. Buy your (ex)employees things that make them happy. Because let’s face it, without them I’d be a monkey with a powerpoint presentation. No offense to monkeys really. I love animals.

5. Throw fun parties. And this being San Francisco, most of my guests will be smarter than me and way more accomplished. Note the tall handsome dude in my kitchen is Coach Mike Brown (former head coach of the Cleveland Cavaliers, my Los Angeles Lakers and now with the Warriors).

Some of my guests (after I explicitly asked them not to) asked him questions like, “Who was worse to coach – Lebron or Kobe? Tell the truth Coach!”

In Silicon Valley for some reason we lack social graces.  #Aspergers

Or have dinner with celebrities. Not because they like you but because you paid for a fundraiser dinner benefitting a charity you actually know very little about. 

“Yo Yao!” I said, but I don’t think he got my sense of humor. Man I love basketball.

And have a real convo with your childhood idol. When I was a kid I loved Janes Addiction. Being able to talk about the music industry with lead singer Perry Farrell was a dream come true.

6. Retire your parents. It’s an Asian thing I guess.

My baby cousin and her husband are both so smart and good looking and young they make me want to puke.

7. Speak at your university and drink beer with students like you’re still an undergrad. And actually puke.

Or people from far off countries will ask you to come speak about startup life, which was also great for me considering I would never had gone to Norway otherwise. competitor

And for some reason after you have an IPO or exit, people who own boats invite you onto them. I never knew some many people owned boats. And you know what? Everyone is in a great mood on a boat. You never hear of a fistfight breaking out on a boat. Am I right?

8. Do “VIP” stuff like become a judge for a foreign country’s Miss Universe pageant.

One of my (ex)employees saw this pic of me “judging” on the event’s Facebook page and she slacked, “JK, I’ve never seen you look so content.” She was joking I’m certain.


Or get invited to the White House and chill with politicians.

Charlie Rangel may have left his office with some controversy (after decades of public service) but he’s still one of the best sales professionals to ever pitch. I wish I could’ve gone drinking beers with him afterwards.

Traveling the world for a year makes you very bereft of potential girlfriends dates (ok, so I didn’t have a lot of dates before then either) so my friend Kyra packed her dress, hopped on a flight to D.C. and came to my rescue as my +1 for the White House gala. Thanks pal – I’m lucky to have friends like you.

9. Become an angel investor and support other amazing founders by hustling hard for them. Cliche but true, in this town you must add value to get into good deals when you’re writing checks as small as mine.

10. Start to miss your desk at work. When you had a job. And purpose.

Also, even your friends at Facebook seem to be working on interesting projects, and so inevitably you get back to f**king work like a real grown up.

Still, my year off the grid was memorable and I’m glad I had it. Whenever people say crap like, “I wish I could have a year like that, JK,” I always tell them, “if you really want it, then –
