If you’ve ever received a Calendly link, congratulations: you’ve participated in one of the most effective marketing
loops on Earth. It’s the digital equivalent of “try one bite” and suddenly you’re asking for the recipe, the chef’s
phone number, and the brand of olive oil used in the dressing.

But here’s the part most people miss: turning a product that spreads like a friendly virus into a grown-up,
enterprise-ready revenue machine requires more than a great link. It takes a modern marketing tech stack, a ruthless
obsession with customer experience, and the kind of operational clarity that makes spreadsheets purr.

Enter Jessica Gilmartin, Chief Marketing Officer of Calendly, who’s spent her career mixing creativity with
data-driven discipline (and yes, she’s also been a yogurt entrepreneurmarketing people contain multitudes).
In the spirit of “My App Stack,” we’re diving into the apps she leans on, why they matter, and what her tool choices
reveal about how modern CMOs actually run go-to-market (GTM) in 2026.

Who Is Jessica Gilmartin (and Why Should CMOs Care)?

Jessica’s path to the CMO seat is the opposite of a straight linewhich, honestly, is the most believable thing
about marketing leadership. She’s talked openly about starting in investment banking, heading to business school,
and realizing that marketing was the sweet spot where the left brain (numbers) and right brain (story) can finally
stop fighting in the group chat.

Before Calendly, she held go-to-market leadership roles across high-growth companies, including leading revenue
marketing at Asana and building enterprise marketing engines at startups. The throughline is consistent:
build systems that scale, then build trust so humans actually use them.

Calendly is a particularly fun playground for that skill set. It’s famously loved by individuals and teams, but
the bigger challenge is helping enterprises adopt it as “the backbone” for complex workflowssales handoffs, inbound
scheduling, recruiting pipelines, customer success touchpoints, and the endless parade of meetings we pretend we’re
not scheduling all day.

The Core Question: What’s in Jessica Gilmartin’s App Stack?

In a “My App Stack” feature, Jessica shared a core set of tools that power her marketing operations and team
execution. The list is refreshingly practical: not a sci-fi stack, not a “we built our own internal tool called
NimbusFalcon,” just the apps that keep a modern marketing org running.

Jessica’s Core App Stack (at a glance)

• Calendly (because of course)
• 6sense (account intelligence and buying signals)
• Marketo (marketing automation)
• Braze (customer engagement and lifecycle messaging)
• Slack (team communication)
• Google Workspace (docs, email, calendars, the classics)
• Asana (work management)
• Zoom (meetings that could’ve been emails, but aren’t)
• Optimizely (experimentation and testing)

She also called out Ada as an “undiscovered gem”a clue that her stack isn’t just about marketing
messaging. It’s about creating a smooth customer experience even when you’re disqualifying leads or routing someone
away from sales.

What This Stack Says About Calendly’s Marketing Strategy

Tool choices are never neutral. A CMO’s app stack is basically a public diaryexcept it doesn’t include feelings,
only dashboards. Jessica’s stack points to a strategy built around:

• Personalization at scale (segment deeply, tailor messaging, reduce “blast email” energy)
• Speed-to-lead and friction removal (reduce the “messy middle” between interest and action)
• Hybrid GTM (product-led growth plus a sales motion that doesn’t trip over itself)
• Operational clarity (OKRs, tight workflows, fewer “where is that file?” scavenger hunts)
• Continuous learning (experiment, measure, improve, repeatlike laundry, but with graphs)

Let’s break down the stack by job-to-be-done, because that’s how leadership teams actually thinkno one buys
“marketing automation” because it sounds cute. They buy it because chaos is expensive.

1) Calendly + Zoom + Google Workspace: The “Make It Ridiculously Easy to Meet” Layer

Calendly sits at the top of the funnel and the bottom of the funnel and, frankly, a surprising number of places in
the middle. It’s not just scheduling; it’s conversion infrastructure. If a prospect wants to talk, your job is to
remove every possible reason they might bailespecially the reason called “back-and-forth emails.”

Pairing Calendly with Google Workspace keeps calendars, docs, and communication connected, while
Zoom makes meetings instantly fulfillable. The strategic point isn’t “we use video calls.”
The point is: when intent is high, your system should behave like a trapdoor (in a good way) that drops people
straight into the right next step.

Example: Speed-to-lead without sounding like a robot

Imagine an enterprise prospect clicks “Talk to Sales” on your pricing page. With the right routing rules, they
don’t submit a form and wait in the ancient purgatory of “someone will reach out shortly.” They see qualified
options, pick a slot, get booked, and show up to a Zoom call with momentum still intact. That’s not just efficiency;
it’s customer experience as a revenue tactic.

2) 6sense: The “Stop Guessing Who’s Ready to Buy” Layer

Jessica called 6sense the biggest new addition to her stack. That’s a tell: Calendly is moving
upmarket, and upmarket marketing is a different sport. When you’re selling to teams and enterprises, you need a
cleaner view of account intent, buying stages, and which audiences deserve premium attention.

Tools like 6sense help marketing and sales align on which accounts are “researching quietly” versus “actively
shopping.” It’s the difference between showing up with a helpful message and showing up with the digital
equivalent of shouting “HEY BESTIE!” at someone you met once in 2019.

Where 6sense tends to pay off

• ABM targeting: prioritize accounts with real signals, not just a big logo
• Smarter personalization: tailor offers and content based on where the account is in the journey
• Sales + marketing alignment: fewer arguments, more shared reality

3) Marketo: The “Orchestrate Campaigns Without Losing Your Mind” Layer

Marketo is a heavyweight in marketing automation, and the reason it keeps showing up in serious
B2B stacks is simple: when you’re running segmentation, nurture, lead management, and attribution at scale,
“let’s do it in spreadsheets” stops being charming and starts being a cry for help.

In interviews, Jessica has emphasized personalization and tailoring messaging by segment. That’s much easier to
say than to dounless your automation layer can handle complexity without breaking or turning your team into
full-time workflow janitors.

How a CMO thinks about automation (when it’s done right)

Automation isn’t about sending more emails. It’s about sending the right message at the right time with
the right CTA, then learning what worked and improving the system. The CMO goal is “consistent buyer experience,”
not “inbox domination.”

4) Braze: The “Lifecycle and Customer Messaging That Actually Feels Human” Layer

Many marketing stacks split into two worlds: acquisition (get the lead) and lifecycle (keep the customer).
Braze lives in the lifecycle worldcustomer engagement across channels, product-adjacent messaging,
and coordinated communication that supports adoption.

This fits Calendly’s reality: the product often enters a company through one person who shares a link. The real
growth is turning that spark into a team standard. Messaging that helps users discover “aha” moments, understand
features, and invite colleagues is a huge part of making a viral product become an enterprise platform.

5) Optimizely: The “Test Everything, But Don’t Test Randomly” Layer

Optimizely signals a commitment to experimentationtesting website experiences, messaging, CTAs,
and flows. For a PLG-adjacent company, the website isn’t just a brochure; it’s often the primary demand capture
engine. A small lift in conversion or better CTA placement can compound into serious pipeline.

The trick is not turning experimentation into a hobby. The best teams test based on a point of view:
what do we believe will reduce friction, increase clarity, and help users self-select the right path?
Optimizely helps you prove it (or get humbled quickly, which is also a gift).

6) Asana + Slack: The “Operational Clarity and Team Sanity” Layer

Jessica has talked about being “obsessed” with clarityOKRs, KPIs, communication, and making sure teams understand
what success looks like. That leadership style maps perfectly to Asana and Slack:
one system to manage work, one system to keep communication fast and visible.

In practice, this is how marketing stops being a set of heroic last-minute sprints and becomes a repeatable machine.
Work management makes dependencies visible, deadlines real, and handoffs less… interpretive.

CMO-level use cases for Asana

• Campaign operating rhythm: launches, content, events, and web work in one system
• Cross-functional coordination: fewer “wait, who owns this?” moments
• OKR tracking: keep goals tied to work, not just a slide deck

Slack as a “learning system,” not just chat

Jessica has described staying current by participating in marketing communities and bringing insights back to her
teamoften via Slack. That’s a subtle but powerful move: the channel becomes a distribution system for ideas,
vendor feedback, and real-world tactics, not just memes (though memes are important cultural infrastructure).

7) Ada: The “Undiscovered Gem” That Reveals a Bigger GTM Story

Jessica called Ada a secret gem, and it makes sense when you look at Calendly’s hybrid motion.
In a PLG business, you can’t send every inbound lead to a human without breaking unit economics. But you also can’t
treat people like trash when they don’t meet qualification criteriabecause today’s “not now” could be tomorrow’s
enterprise champion.

A smart chatbot layer supports two goals at once: efficiency and customer experience. It’s the polite bouncer at
the door who still hands you a map, not the one who yells “NEXT!” like you’re at the DMV.

How the Stack Supports Calendly’s Move Upmarket

Calendly’s challenge is classic: a beloved, viral product known for a simple use case (“here’s my link”)
has to tell a larger storyenterprise workflows, routing, analytics, integrations, and measurable ROI.

Jessica has emphasized shifting the narrative from pure time savings to business value and ROIespecially for
senior decision makers. That requires:

• Better segmentation (know who needs what story)
• Personalized messaging (tailored paths, not one-size-fits-all campaigns)
• Clear calls-to-action (sign up, demo, talk to salesbased on intent)
• Fast, satisfying experiences (routing + scheduling + support, all connected)

Put differently: this stack is built to convert interest into action without losing trust. That’s the whole game.

What Marketers Can Steal (Legally) From Jessica Gilmartin’s App Stack

1) Build for the customer journey, not the org chart

Notice how the tools map to journey moments: discover → engage → convert → adopt → expand. If your tools only map
to internal departments, your customer experience will feel like a relay race where everyone drops the baton.

2) Personalization is a system, not a copywriting trick

If you want tailored messaging, you need data + automation + testing. Otherwise you’ll “personalize” by adding
{FirstName} and calling it a day. (Your buyers can tell. They always can.)

3) Operational clarity is a growth lever

Asana and Slack aren’t glamorous, but they’re how strategy becomes execution. If you’re constantly re-explaining
priorities, you’re paying a tax on every initiative.

4) Customer experience isn’t a departmentit’s the product

The inclusion of Ada is the giveaway. Great marketing isn’t just “getting leads.” It’s designing interactions so
people leave feeling helped, even when the answer is “not a fit right now.”

Conclusion: The Stack Behind the Scheduling Link Everyone Knows

Jessica Gilmartin’s app stack is a masterclass in modern B2B marketing operations: intent data to focus efforts,
automation and lifecycle tools to personalize at scale, experimentation to keep improving, and work systems that
make the entire machine run without burning out the humans inside it.

And maybe the most important lesson is this: the best stacks aren’t “more tools.” They’re fewer tools that connect
cleanly to the customer journey and reinforce a clear strategy. If your marketing stack makes it easier for your
customers to take the next stepand easier for your team to do great workyou’re winning.

Bonus: of Real-World Experience (Because Tools Don’t Use Themselves)

I’ve tried building “a Jessica-style stack” in smaller marketing teams, and here’s what I learned the hard way:
the tools are the easy part. The hard part is choosing a philosophy and then refusing to abandon it the moment
someone says, “Can we just do this one thing manually this one time?”

The first time I introduced a serious work management system (Asana, in my case), everyone nodded politelythen
continued to run the team out of Slack DMs like it was a secret underground railroad of half-finished tasks.
The fix wasn’t more training. It was leadership deciding, “If it’s not in Asana, it doesn’t exist,” and sticking
to that rule long enough that the team stopped testing the boundary like toddlers at bedtime.

Next came personalization. We wanted that “tailored messaging by segment” magic, so we built segments… and then
promptly forgot to create differentiated offers. Classic. The biggest upgrade wasn’t fancy tooling; it was writing
a simple segmentation brief that forced us to answer three questions: Who is this segment? What do they care about
right now? What is the next best action for them? Once we had that, automation finally felt helpful instead of
performative.

Experimentation was another humbling chapter. We added testing (Optimizely-style thinking, even if the tool varied)
and discovered that “test everything” is code for “learn nothing.” The breakthrough was narrowing the focus to
friction points: pricing pages, demo flows, and the CTAs that confuse people. When you test the moments where users
hesitate, you don’t need a thousand experimentsyou need a handful that actually change behavior.

And then there’s routing. Every marketing team loves leads, but not every lead loves you back. When we built a
lightweight qualification and routing experience, we found that disqualifying with kindness matters. If someone
isn’t a fit for sales, you can still give them a useful next step: a guide, a webinar, a support option, or a
self-serve path that respects their time. That’s where the “Ada mindset” clicks: automation should reduce human
effort without reducing human dignity.

The most practical takeaway from Jessica Gilmartin’s app stack is this: pick tools that support a coherent buyer
experience, then build team habits that keep those tools honest. The stack isn’t the strategyit’s the scaffolding
that makes strategy repeatable on a Tuesday afternoon when nobody feels inspirational and the quarter is still
happening whether you’re ready or not.
