In any early-stage tech company, having data is easy; making data useful is the challenge. As industry experts note, “tools don’t decide outcomes; culture does”. Kawano, a Product Growth and Analytics leader at Meta, echoes this: tools and dashboards mean little unless they serve clear goals. He advised founders to start by defining those goals, asking “What business outcomes do we want to drive with data?” before instrumenting systems or hiring data scientists. Without that alignment, teams can “get inundated with unnecessary reports or end up chasing vanity metrics” that look impressive but aren’t actionable. From his time leading global product and trust initiatives at Meta, Kawano argues that the first requirement is clarity of purpose: every data point must connect to a strategy. Kawano’s background, an academic grounding combined with social-impact projects, shows in his emphasis on fairness and ethics. He treats scale and responsibility as inseparable. Modern AI experts warn that fairness must be “actively built into the system,” or else analytics will bias decisions and “risk harming individuals and eroding trust”. At Meta’s scale, Kawano saw how even small data assumptions can amplify when millions of users are involved. He learned to keep initial tracking simple and agile: measuring basic engagement (like daily active users) to guide the team, rather than waiting to perfect every metric. As one startup guide counsels, in early phases, “you can’t afford analysis paralysis” – speed and iteration outweigh over-engineering. Below are Kawano’s ten best practices for data discipline, drawn from these lessons: Define clear objectives before collecting data Define clear objectives before collecting data Align analytics with the startup’s mission from day one. Ask the big questions: What problem are we solving? What decisions will data inform? Experts recommend connecting every metric to an outcome: “What business outcomes do we want to drive with data?”, rather than collecting data for its own sake. This focus helps avoid vanity metrics. As Day1Data warns, without a shared understanding of purpose, teams drown in reports or end up chasing vanity metrics. Kawano agrees that clarity up front prevents wasted effort later. Keep early data collection simple but structured Keep early data collection simple but structured Instrument your product right away, but don’t overbuild. Kawano urges founders to track basic user events and core metrics with as much granularity as reasonable, so the system can evolve. As Mode Analytics advises, encourage engineers to make detailed event tracking an integral part of the development process from day one. At launch, simple indicators (signups, usage frequency, funnels) often suffice to know if you’re on track. Crucially, he warns, don’t over-engineer metrics too soon. In early startup phases, “simple measures of engagement like DAUs ... ensure you’re headed in the right direction”. Start with the essentials, so you can learn quickly and pivot without rebuilding your analytics. track basic user events and core metrics don’t over-engineer metrics too soon Balance build vs. buy for your data stack Balance build vs. buy for your data stack Be pragmatic about tools. Kawano learned at Meta that building a custom system offers flexibility, but buying solutions speeds time to value. Data leaders say the choice “depends on budget, expertise, and time-to-value”. If you have top engineering talent and unique needs, building in-house might pay off. If not, using managed cloud services can accelerate insights. For example, a Monte Carlo Data case study found that building a data-quality tool in-house would cost ~$450K/year plus hours of developer time, a heavy investment that might be avoided by an off-the-shelf service. The takeaway: weigh developer costs and hiring risks (many engineers prefer working with industry-standard tools) versus vendor lead times. Buying often gives faster implementation, but only you know your team’s bandwidth and security requirements. Ensure data quality and trust from day one Ensure data quality and trust from day one Data is only as good as its accuracy. Kawano emphasizes building in validation immediately. As one analytics expert puts it, “No matter how advanced the technology, every initiative that depends on data is only as strong as the quality of the data itself”. In practice, this means adding basic data-cleaning, schema checks, and monitoring alerts from the start. Remember: all data “flows from creation to consumption… contamination at the source affects everything downstream”. By enforcing standards (no duplicate keys, consistent formats, etc.) early, you avoid an unreliable foundation. Over time, poor data quality could stall your analytics ROI – Kawano’s playbook is to prioritize accuracy so that teams learn to trust and act on the numbers. Prioritize privacy, security, and compliance early Prioritize privacy, security, and compliance early Even as a small startup, respect user data and regulations now. Kawano advises that privacy and security aren’t optional extras but fundamentals. Industry guides emphasize that “implementing the right privacy and security practices from the outset is crucial to avoid vulnerabilities”. In concrete terms, this might mean encrypting PII, using secure cloud infrastructure, or planning for GDPR/CCPA compliance as you design features. Startups may be tempted to defer these for later, but Kawano reminds founders that demonstrating data responsibility builds customer trust and avoids costly retrofits. With regulations tightening, showing early compliance can even be a competitive advantage. Make data accessible across teams (no gatekeeping) Make data accessible across teams (no gatekeeping) A data culture thrives when insights are democratized. Kawano insists that everyone, not just data analysts, should be able to ask questions of the data. For example, Day1Data notes that a data-driven culture “cannot thrive if data is locked behind technical barriers”. Likewise, experts advise making dashboards and key metrics visible and understandable to each team. Build cross-functional data repositories or no-code tools so that marketers, product managers, and engineers can self-serve answers. At the Meta scale, he saw the alternative: bottlenecks and siloed decisions. Instead, adopt a model like other tech giants: “data must be accessible across all levels of the organization,” empowering employees to make data-informed decisions at every level. Good governance still matters, but it’s better to guide responsible use than to lock data away. Use data for experimentation, not just dashboards Use data for experimentation, not just dashboards Kawano champions a test-and-learn mindset. Rather than treating analytics as a rear-view mirror, use it to hypothesize and iterate. Encourage teams to run experiments, A/B tests, prototype features, pilot campaigns, and measure outcomes rigorously. This aligns with the “test-and-learn” cultures of Facebook, Google, and others, where data guides decisions on features and marketing. In practice, every product or UX change becomes an experiment: frame a hypothesis, collect data, and adjust based on evidence. Kawano notes that instilling this ethos early makes data a tool for discovery. Instead of just building static dashboards, build rapid feedback loops: let insights from analytics prompt new ideas and improvements. Document and communicate data workflows Document and communicate data workflows Explicit documentation is non-negotiable. Kawano’s teams always map out where data comes from, how it’s transformed, and where it goes. This clarity avoids confusion when new members join or when problems arise. Best practices from Secoda emphasize that “documenting data pipelines is crucial for onboarding… troubleshooting issues, maintaining systems, and ensuring compliance”. Without it, companies risk downtime and chaos. Kawano recommends maintaining a shared data dictionary and flow diagrams so everyone “understands key metrics”. In short, write down the architecture: list data sources, ETL jobs, schemas, and dashboards. Then communicate these workflows to the whole team. As experts warn, if pipelines aren’t clear, you incur inefficiencies and compliance gaps. This discipline builds trust; people trust data they can trace. Design data systems that evolve and scale Design data systems that evolve and scale Plan for growth from the start. Kawano advises using modular, cloud-friendly architectures that can expand. A recent guide notes that startups should “start with a minimal viable setup and expand gradually”. This means picking components (data warehouse, ETL, BI tools) that can handle bigger loads later, even if you use only a fraction at launch. Similarly, Monte Carlo Data points out that modern data stacks become “more fragmented” as companies scale; today’s home-grown solution may not plug into tomorrow’s AI tools. Kawano therefore recommends using managed platforms (Snowflake, BigQuery, dbt, etc.) when possible, since they support flexibility. The goal is to avoid a complete redesign in year two. By choosing tools and architectures that embrace change, you ensure your analytics keep up with higher traffic and more users. Avoid over-engineering or chasing vanity metrics Avoid over-engineering or chasing vanity metrics Less is more at first. Kawano warns startups not to fall into the trap of sophisticated analytics before mastering the basics. In the early days, focus on the few metrics that matter. Mode’s analytics guide puts it bluntly: until product-market fit, you “can’t afford analysis paralysis”. Likewise, Day1Data cautions that without purpose, companies “chase vanity metrics” that don’t move the business. In practice, this means: Limit KPIs to those tied to growth or retention, not every possible number.Build lightweight pipelines at first and postpone complex modeling.Revisit metrics regularly: drop any that weren’t cited in decisions. Limit KPIs to those tied to growth or retention, not every possible number. Build lightweight pipelines at first and postpone complex modeling. Revisit metrics regularly: drop any that weren’t cited in decisions. By keeping the stack lean and the dashboards clean, you retain agility. Kawano’s own teams have found that solving actual problems with data often involves cutting out the noise, not adding more layers of analysis. Key lessons from Meta Key lessons from Meta Kawano’s tenure at Meta (Facebook) reinforced these points at an extreme scale. Running global products taught him that agility is a must: instead of debating perfect definitions for weeks, teams at Meta often make provisional decisions and iterate. As one startup playbook notes, even large companies avoid “analysis paralysis” by focusing on immediate signals. He also witnessed how powerful clarity and documentation become when thousands of engineers and analysts work in parallel. Missing context in a dashboard or pipeline can cause critical failures; experts warn that without proper documentation, the risk of downtime “increases significantly”. In short, Kawano saw that at tech giants, decentralized teams only thrive when everyone shares a single source of truth, a lesson he applies by keeping metadata catalogs and data contracts up to date. Final advice for founders Final advice for founders In Kawano’s view, the real payoff of data discipline is cultural. He reminds founders that building “a culture of clarity, trust, and agility with data” is far more impactful than any early-stage big-data project. As Day1Data puts it, “Tools come and go... but culture, how people think, communicate and make decisions, is what determines whether data becomes a strategic advantage”. Rather than chasing hype, focus on transparency. Encourage open discussion of what the numbers mean, reward learning from failures, and integrate data into your processes so it becomes a natural part of decision-making. A small startup with disciplined, well-communicated metrics will outpace a disorganized, bigger one every time. In the end, Kawano’s playbook is simple: get the basics right, build trust in your data from day one, and let curiosity and evidence, not ego, drive product choices.
