2. Archana Agrawal - Head of Cloud Marketing, Atlassian

With a background in computer science and engineering, plus an MBA from Harvard, Archana Agrawal seems the perfect profile to head up global marketing for all of Atlassian’s cloud products. That includes JIRA, Confluence, Bitbucket, JIRA Service Desk, and HipChat. Her years of experience in analytics and data science, both at Atlassian and at, no doubt shape a strong evidence-based, data-driven approach to marketing. At SaaStock, she’s sharing tactical advice anyone in the audience can adopt, in her keynote, "Building an Enduring Growth Marketing Practice." The operative word here is “enduring” -- this knowledge is not for quick fixes to show great numbers next quarter. These are tactics for sustained, healthy growth that may just lead to a ten-year streak of your own.

3. Scott Heimes - Chief Marketing Officer, SendGrid

Not many companies can claim to have customers like Airbnb, HubSpot, Spotify, and Foursquare. SendGrid can, sending over 30 billion emails through its platform each month, sitting pretty on the Series D they raised last autumn. And they’ve entrusted this phase of their mammoth growth to Scott Heimes. At SendGrid, Heimes is responsible for brand strategy, demand generation, global marketing operations, and all the little (and big) things that fall under those umbrellas. He has the background for it, as he served as CMO for two other companies, Digital River and WebMD, plus holding other senior leadership marketing roles. He is dropping in at SaaStock to present SendGrid’s journey and key takeaways for scaling a SaaS business. Don’t miss his keynote, "Reaching the Next Summit: SendGrid's Growth Story and Five Keys to Scaling for Long-Term Success."

6. Steli Efti - CEO and Co-Founder,

Steli Efti hardly needs an introduction, but here we go. For one, he’s one of the most well-known figures in SaaS Sales, beloved for his product - an inside sales CRM. Efti has also made a name for himself through his knowledge and his personality; he’s a tell-it-like-it-is, motivational educator. What you may not know about Efti is that he has other projects going on, too. For example, he’s the Co-Founder and CEO of Elastic, a Sales-as-a-Service business that helps startups build and manage sales teams on demand. If you are well organized, you can snap a seat to see him at the Sales Bootcamp during SaaS.City.

Just check out the blog for articles and videos, all in Efti’s signature candid style.

7. Nathan Barry - CEO and Founder, ConvertKit

Nathan Barry has a background in designing and marketing apps, some of which he has made just for himself. Thankfully he has shared one in particular with the world: ConvertKit, the email marketing tool for professional bloggers. However, his passion for beautifully-designed apps goes further than running a successful business out of one. He loves to teach others how to do it. He wrote The App Design Handbook, a guide to designing iOS applications, and often writes on his personal site. For his talk at SaaStock, he’s getting down to business, sharing his experience of "Using direct sales to bootstrap [ConvertKit] to $8M ARR." Plenty of learning for the bootstrappers out there.

8. Kyle Porter - CEO and Co-Founder, SalesLoft

Kyle Porter started SalesLoft out of a desire to help salespeople achieve their goals and simultaneously “serve customers with sincerity and empathy.” Sincerity and empathy, in the stereotypically cut-throat world of sales? That’s a lofty goal (pun intended), and Porter has succeeded at it. SalesLoft started in 2011, just closed its Series B earlier this year. With his experience providing a sales tool to over 30,000 business professionals, Porter is coming to SaaStock and speaking in three different sessions. First, at SaaS.City on Monday, he rolls up his sleeves in the Sales Bootcamp. Then he’ll deliver his keynote: "What the top sales people in the world are doing right.” Finally, he’ll also participate in a SaaStock panel titled, "How Modern Business will succeed: Think like a startup.” With three opportunities to catch him in Dublin, there’s no excuse to miss out!

9. Jacco van der Kooij - Founder, Winning by Design; Storm Ventures

Jacco van der Kooij is a SaaS sales guru, which he attributes to the homegrown values on which he was raised: build trust, maintain integrity, work hard, help others. His expertise in SaaS Sales has led him to become an entrepreneur and educator; he even moonlights as a mentor on the investor side from time to time! Winning By Design is in its sixth year of diagnosing, training, designing, and optimizing SaaS sales organizations all around the world. Customers include AdRoll, DroneDeploy, Fliptop (acq by LinkedIn), FreshDesk, Gainsight, Prezi, SendGrid, TapInfluence, and YesWare. When Jacco is not helping WBD’s customers, he is most likely advising the portfolio companies of Storm Ventures or Reach Capital. And when he’s not doing that, he’s probably writing on his personal blog, Future of Sales is NOW, to help educate the rest of us folks. We welcome him to SaaStock for two sessions. At SaaS.City, he’s running a three-hour, practical workshop on "Getting from $1 to $20M ARR.” Each attendee will receive a paperback copy of his book, Blueprints for a SaaS Sales Organization. But act fast, as the session is limited to 48 attendees! Later on at SaaStock, he’ll deliver his keynote talk, "Hope is not a Strategy. Sales is not a Tactic." He recently told us SaaS is Dead, but instead of leaving us to despair over that, he gave us the medicine to resurrect it.

15. Florian Jourda - 1st Engineer, Box

Customer Success

16. Rav Dhaliwal - Head of Customer Success (EMEA), Slack

Slack became a $1B company in two years, one user at a time. People simply LOVE the product.

His current role focuses on building Slack’s presence in the UK and EMEA, as well as building the Global Customer Success team. His experience consists of customer success and support roles at tech-heavy hitters, such as Zendesk, Yammer,, and IBM. Given Slack’s numbers, and that past employer lineup, you don’t want to miss Dhaliwal’s appearance on the panel, "Scaling Customer Success at Fast Growth Companies."

17. David Apple - VP of Customer Success, Typeform

It makes sense that someone who studied mechanical engineering as an undergrad, and who later got an MBA, ends up at the top of Customer Success for a data collection tool that is leading its industry by leaps and bounds. That’s David Apple at Typeform. Over the last three years, his responsibilities have grown to include customer support, customer experience, account management, sales, and CS operations. He’s coming to SaaStock and delivering in three ways. On Monday at SaaS.City, he’s getting all practical and tactical at the Customer Success Bootcamp. Then he’s joining fellow experts on the panel of "Scaling Customer Success at Fast Growth Companies." And finally, he’s bringing an insider story from the office, titled, "How Typeform presented their retention story at their last board meeting.” A lot up his sleeve.

Though recurring billing can get complicated with various use-cases, freak one-offs, and other challenges, Chargebee is committed to providing a seamless and flexible experience to its users, the first and vital step to making them successful. On this topic, Krish will share his insights at SaaStock with a keynote talk, "The New Normals in Customer Experience."

20. Dan Steinman - Head of EMEA, Gainsight

His track record includes serving as VP of Customer Success at Mozes and Marketo, both of which have been acquired since his time there. Gainsight keeps growing, with over $156M in total funding from 11 investors, the latest Series E $56M sealed this past May. You have two chances to see him.

Ryan Smith’s Qualtrics is a success story that dreams are made of.

This past April, Qualtrics announced a whopping $180M funding round to power its next innovation: Qualtrics XM platform.

It lays the groundwork for everything else to happen.” At SaaStock, Rachel will share her wisdom and tactical advice on scaling a team from Montpelier to Kansa City in her keynote titled "Out of sight, but not out of mind: Expanding and managing teams overseas."

24. Tope Awotona - CEO, Calendly

Like any great founder, Tope Awotona spotted a pain point while going about his usual employment.

Tope has some unique learnings to share about structuring your business, from using Freemium as a catalyst for growth, to figuring out how to position your SaaS, when you have diverse users, a topic he talked about on the SaaS Revolution Show.

Still, an engineer in her heart, her recent forays, and current studies include a dip into AI at Singularity University and Udacity.
