“The real challenge isn't just building the AI, it's understanding and managing the resources it consumes to make it a sustainable solution.”

Francis Carter, 29, is a Product Manager based in Dublin, Ireland, with a BA in Economics. He joined his current startup, a rapidly growing tech company focused on customer support solutions, three years ago, quickly gravitating towards product management after a brief stint in business analysis. His economic background instilled a deep appreciation for quantitative analysis and structured decision-making, which he now applies rigorously to his product work. Francis leads the product efforts for an 8-person app team currently piloting an innovative AI support triage flow. This role demands a unique blend of technical understanding and business acumen. A significant portion of his workday is dedicated to monitoring the pilot's performance, specifically tracking token volumes from the engineering dashboard. These metrics are crucial for him to set realistic experiment budgets and provide accurate cost projections in planning documents shared with the company's founders and engineering leads. He sees this AI feature as a critical test case for the company's future, and the pressure to demonstrate its viability is palpable. Outside of work, Francis is an avid runner, training consistently for half-marathons, which he finds essential for maintaining mental clarity and physical well-being amidst the demands of his role. He lives a relatively frugal but comfortable life, prioritizing saving and investing over conspicuous consumption, reflecting his pragmatic approach to financial planning. He values efficiency and measurable outcomes, constantly seeking ways to optimize processes, both in his professional life and personal routines. His career goal is to ascend to a senior product leadership position, driving impactful AI-driven products, while ensuring he maintains a sustainable work-life balance.

Background & daily life

A day in their life

Francis's typical weekday starts around 6:30 AM with a run. After a quick breakfast and coffee, he's online by 8:30 AM, checking Slack and email for urgent issues. His mornings are often filled with stand-ups, backlog grooming sessions, and deep dives into product analytics dashboards, specifically monitoring the AI pilot's token usage and performance metrics. Lunch is usually a quick affair at his desk. Afternoons involve cross-functional meetings with engineering and design, refining experiment parameters, and preparing documentation for upcoming planning sessions. He aims to log off by 6:00 PM, but often checks emails one last time before dinner.

Lifestyle

Francis lives in a rented two-bedroom apartment in Rathmines with a flatmate, a software engineer. His income allows for comfortable living but he's mindful of saving for future investments. He's a creature of habit, waking early for a 5k run most mornings, followed by a strong black coffee and a quick scan of overnight tech news before his commute. Weekends often involve exploring Dublin's cafes, catching up with friends, or planning his next half-marathon training block. He enjoys cooking simple, healthy meals and occasionally hosts small gatherings.

Work life

Francis's days are a blend of strategic planning and tactical execution. He spends significant time in Jira, refining user stories and prioritizing the backlog for his 8-person app team. A core part of his role involves monitoring the AI support triage pilot, scrutinizing token volumes via the engineering dashboard to inform experiment budgets. He meticulously documents these estimates and projections for planning docs shared with founders and the engineering leads. He thrives on the fast-paced startup environment but feels the pressure to demonstrate clear ROI from the AI feature.

Relationships

Francis maintains strong professional relationships with his 8-person app team, valuing their technical input and collaborative spirit. He reports to the Head of Product, with whom he has a good working rapport, and frequently interacts with the CTO and CEO regarding the AI pilot's progress. His social circle is tight-knit, primarily consisting of university friends and running club acquaintances.

How they decide

Francis approaches decisions with a strong emphasis on data and structured analysis. He gathers relevant metrics, consults with his team, and maps out potential outcomes before committing to a path. He values consensus but ultimately relies on objective evidence and logical reasoning to make the final call, especially when it involves resource allocation or strategic direction.

How they sound

Speaks with a clear, measured cadence, often using precise language. He avoids overly casual slang in professional settings but is comfortable with technical jargon. His tone is generally calm and rational, even when discussing complex or challenging topics. He tends to frame his points logically, often referencing data or past decisions. He's not prone to hyperbole and prefers direct, factual communication.

Questions & answers

  1. You land on https://costmytokens.com/ (Cost My Tokens) for the first time. What's unclear, what makes you leave, and what would make you sign up?

    The core functionality of calculating LLM API costs is clear, and the ability to do so without sign-up is a definite plus, especially given my need to quickly estimate budgets. What's less clear initially is how the token counting for models without direct browser tokenizers is handled, and I'd want to understand the verification process for these estimates. While the listed prices are helpful, seeing potential variations or actual gateway prices alongside official ones would be valuable. The "Batch (50% off where offered)" tier is intriguing, but it's not immediately clear if that's applicable to all models or how to access it. To sign up, I'd need more transparency on the methodology for non-official token counts and perhaps a way to save and compare multiple model projections over time for future planning.
