6 Key Concepts
Product Strategy
A product strategy is an integrated set of choices that define how a company will succeed in its chosen market. It answers questions about winning aspirations, target markets and segments, specific personas, and the approach to winning with that audience, ultimately guiding prioritization by clarifying where to play and where not to play.
Product-Led Growth (PLG)
PLG is a business model where the product itself drives user acquisition, activation, conversion, and retention. Historically, Calendly's growth was almost entirely product-led, relying on its viral loop and self-service model.
Sales-Led Growth (SLG)
SLG is a growth model that involves a direct sales team to acquire customers, often targeting larger accounts or specific departments. Calendly has transitioned from a purely PLG model to incorporating an SLG motion, which is now its fastest-growing segment.
OPA (Opportunity Problem Assessment)
OPA is a meeting within Calendly's product team where product managers debate and discuss problem spaces or evaluate opportunities. It serves as a forum for PMs to spar and think through potential work, deciding whether to move forward with developing solutions.
Competitive War Gaming
A quarterly exercise at Calendly where teams are assigned a competitor, immerse themselves in that competitor's product, conduct a SWOT analysis, and present their findings. This helps the company stay informed about the market and refine its own strategy.
Product Development Lifecycle Phases
Calendly structures its product development into distinct phases: Discovery (researching a problem space), Solutioning (exploring and user-testing solutions), Build (developing the chosen solution), and Launch, Measure, and Iterate (releasing the product and refining it based on performance).
12 Questions Answered
To avoid awkwardness, first open the door for the recipient to share their availability. Alternatively, use Calendly's 'add times to email' feature to paste specific available times directly into your email, reducing friction for the recipient.
Paths include applying to formal Associate Product Manager (APM) programs, applying to junior PM roles via internal job boards (especially from product-adjacent functions), seeking opportunities to shadow or partner with PMs and take on product work, or joining an early-stage startup where roles are often fluid.
Building a successful APM program requires significant investment and intentionality, including clear interview processes, defined role expectations, training elements, and sufficient capacity to set participants up for success, which many companies at earlier stages may not have.
Calendly's product organization includes product managers, designers, a research team, and product operations. Teams are structured around core user experience (features and growth for core personas), enterprise (IT admins and departmental leaders), and platform (integrations and APIs).
Calendly narrowed its overall product strategy and target market, segments, and personas. This clarity allows product managers to prioritize more effectively, saying 'no' to features outside the core focus and delivering better value for target users.
Calendly primarily grows through a viral loop, where 70% of signups come from recipients of Calendly links. These solo users then invite team members, leading to team adoption, which can eventually convert into larger organizational deals through sales.
It's crucial to hire sales reps suited for an inbound motion (grower profile) in the early stages, as opposed to heavy outbound hunters. Additionally, ensure the sales team's profile matches the target buyer, which initially tends to be department heads rather than IT or CIOs.
Product leaders should approach the sales team with customer empathy, viewing them as a valuable asset for getting closer to the customer. Sales teams talk to many more customers than product managers, providing critical insights for product decisions.
Prioritization starts with a clear, multi-year product strategy defining where Calendly will play and how it will win. This strategy is broken down into annual company OKRs with quarterly milestones. Product work and resource allocation are then directly aligned to support these OKRs and strategic horizons.
Calendly's founder, Tope Awotona, initially hired an outside development firm in Ukraine. The first 10 users were customer success agents at an education company that contracted with the same firm. These CSMs used Calendly to schedule calls with parents, who then started using it for parent-teacher conferences, leading to organic spread, especially as the product was initially free.
While Calendly is widely known as a solo user tool, its 'teams business' (multiple users in an organization collaboratively scheduling) is growing much faster. This focus on supporting teams and departments in externally-facing roles is seen as the future of growth.
Annie recommends the 'Customize Once and Share' feature, which allows users to make on-the-fly changes to an event type (like title, duration, or date) for a specific recipient without having to create a brand new event type for a one-off tweak.
26 Actionable Insights
1. Narrow Product Focus for Impact
Define a clear product strategy by identifying the specific market, segments, and personas to target, which enables product teams to prioritize effectively and deliver amazing value for a focused group rather than average solutions for many.
2. Define Winning Product Strategy
Use a framework like ‘Playing to Win’ to outline winning aspirations, identify where to play (target markets, segments, personas), and determine how to win with that target audience, which inherently clarifies where not to play.
3. Align OKRs Across Company
Ensure OKRs are tightly integrated from company-level objectives down to department-level key results, with clear dependency mapping and cross-functional plans to support the most important objectives.
4. Instill “Focus Wisely” Principle
Embed a core principle like ‘Focus Wisely’ into the company culture and product development process, enabling executives and teams to make difficult ’no’ decisions and prioritize delivering the highest quality product for target customers.
5. Manage Strategic Focus Shift
Implementing a narrower product focus requires a significant cultural shift across people, processes, and product, especially when transitioning from a broad product-led growth model to a more targeted sales-led approach.
6. Allocate Resources by Strategic Horizons
Allocate product resources across different strategic horizons (e.g., Horizon 1 for immediate needs, Horizon 2 for mid-term growth, Horizon 3 for long-term vision) and adjust percentages over time to align with evolving strategic priorities.
7. Commit to Phased Product Planning
Break down product development into distinct phases (discovery, solutioning, build, launch/measure/iterate) and commit to dates only for the work that is immediately within control, avoiding premature commitments for distant projects.
8. Document Multi-Layered Strategy
Maintain a multi-layered strategy documentation system, including a high-level 3-year company strategy (docs/slides), annual product team OKRs (docs/slides), and project-level templates for feature development (e.g., in Confluence).
9. Leverage Sales for Customer Insight
Product teams should view sales and go-to-market teams as a valuable asset for gaining customer empathy and understanding, as they interact with significantly more customers and can provide crucial insights for product decisions.
10. Structure Product Teams by Persona/Problem
Organize product teams around specific personas or problem areas, such as a ‘Core’ team for end-user features and growth, an ‘Enterprise’ team for IT admins and departmental leaders, and a ‘Platform’ team for integrations and APIs.
11. Integrate Product & Design Leadership
Having product and design functions report into a single leader (e.g., CPO) can ensure a more holistic approach to the end-to-end user experience, integrating problem prioritization with solution delivery.
12. Facilitate PM Problem Debate (OPA)
Implement ‘Opportunity/Problem Assessment’ (OPA) meetings where product managers can frequently debate, discuss, and spar with each other on problem spaces, research findings, and solution approaches, fostering open feedback without leadership presence.
13. Conduct Competitive War Gaming
Organize competitive war gaming sessions where teams are assigned to ‘own’ a competitor for a period, immersing themselves in the competitor’s product, conducting SWOT analysis, and presenting insights to inform company strategy.
14. Reinforce Focus Through Documentation
Reinforce the ‘Focus Wisely’ principle through all documentation, templates (e.g., OPA, PRD), and product review processes, consistently prompting teams to identify the target customer, their needs, and how the solution addresses them.
15. Ask “Why” to Build Scalable Solutions
When engaging with customers, focus on asking the right questions to understand the underlying ‘why’ behind their requests, enabling the development of scalable solutions that meet broader customer needs while preserving the end-user experience.
16. Apply Consumer Product Principles
Apply consumer product development principles, such as funnel optimization, building growth as a discipline, and using data and A/B testing for decision-making, even in businesses that blend product-led and sales-led growth.
17. Hire Inbound-Focused Sales Reps Initially
When transitioning from product-led growth (PLG) to sales-led growth (SLG), initially hire sales reps with an inbound-focused background who are adept at working with proactive leads and product-qualified leads (PQLs), rather than heavy outbound hunters.
18. Match Sales Reps to Target Buyer
Ensure early sales hires match the target buyer profile, focusing on those experienced in selling to departmental heads (e.g., head of sales, recruiting) rather than IT or CIOs, as the buyer persona evolves with company scale.
19. Identify Growth Levers from Customer Usage
Continuously observe how customers are using the product to identify organic ‘pull’ towards new use cases (e.g., teams collaborating) that can inform the next major growth curve, rather than solely relying on speculative feature development.
20. Leverage Early Connections for Growth
For early user acquisition, leverage existing connections, even those through contractors building your product, and consider offering a free tier to reduce friction and encourage viral adoption, especially if the product offers a superior experience.
21. Formal Product Management Entry
Consider applying to Associate Product Manager (APM) programs at scaled companies (e.g., Google, Meta) or even smaller, earlier-stage companies. Alternatively, apply directly to junior PM roles via internal job boards if already working in a product-adjacent function.
22. Informal Product Management Entry
Seek opportunities to shadow or partner closely with a product manager, offering to take on some product-related work. Participate in subject matter expert (SME) programs that pair go-to-market functions with product squads. Another path is joining an early-stage startup where roles are often fluid, allowing you to try product management.
23. Cultivate PM Success Traits
To increase chances of transitioning into product management, demonstrate curiosity, passion for the product and solving customer problems, and consider tinkering with side projects to hone PM skills.
24. Discover APM Programs
To find open Associate Product Manager roles, search for ‘Associate Product Manager’ on job boards like Glassdoor.
25. Engage with CPO Support Communities
For Chief Product Officers and product leaders, engage with communities like ‘Skip’ to gather advice, manage challenges, discuss career growth, and network with peers in similar roles. Follow the Skip community on LinkedIn for more information.
26. Send Calendly Without Awkwardness
When sending a Calendly link, first offer the recipient to share their availability or choose a time from your calendar. Additionally, use the ‘add times to email’ feature to reduce friction by embedding available slots directly in the email.
