The 'Day Job as Runway' Side Project Strategy
A senior engineer at Capgemini is building products like XLSheetAI and Habitide on nights and weekends without quitting his full-time job. He argues the job provides a zero-revenue-pressure runway for experiments, leading to better decisions made from a non-panicked headspace.
The NYC startup scene is a major global player, ranking #2 in the world and the United States, with 11,911 startups and 121 unicorns. The city's tech sector, valued at over $189 billion, added 114,000 jobs between 2010 and 2021, and as of May 2023, Manhattan surpassed San Francisco in the number of early-stage startups. Key platforms for finding engineering roles in this competitive landscape include StartupJobs.nyc, AngelList/Wellfound, and Built In NYC, with networking through local tech meetups and online communities being crucial as many top roles are never publicly posted. For engineers building AI applications, a variety of frameworks are available to simplify development. For fast prototyping, the OpenAI Agents SDK is often recommended, while LangGraph is praised for its debugging capabilities in complex agentic systems. Multi-agent systems can be orchestrated using frameworks like CrewAI for role-based tasks and AutoGen for debate-based problem-solving. Microsoft has also entered this space with its own open-source agent framework that supports both Python and .NET. The indie hacker path, bootstrapping a project to profitability, is a well-documented journey. Tony Dinh, for example, grew his audience on Twitter to 97,000 followers and now earns approximately $45,000 a month from his suite of products that includes TypingMind and DevUtils. Similarly, Mattia Righetti's project, BlackTwist, reached $2,000 in monthly recurring revenue after he took on a full-time Product Manager role to alleviate financial pressure. These stories often highlight the importance of building in public and leveraging social platforms for initial user acquisition. Venture capital investment is heavily skewed towards AI, with AI-focused startups capturing about a third of all global VC dollars in 2024. In the first half of 2025, 64% of U.S. venture capital was invested in AI startups. This trend is creating a competitive environment where non-AI startups may face more difficulty securing funding. Investors are showing a preference for AI companies with clear, enterprise applications and those building critical AI and cloud infrastructure. For consumer and social apps, a multi-channel user acquisition strategy is critical. App Store Optimization (ASO) is foundational, focusing on relevant keywords and compelling visuals to increase visibility. Beyond the app stores, social media advertising, influencer marketing, and referral programs are effective channels for reaching new users. It is also important to define a narrow target audience to avoid wasted ad spend and to focus on acquiring high-quality users who are more likely to remain engaged. Vertical SaaS, which targets specific industries like healthcare or real estate, is a rapidly growing market. These specialized solutions offer deeper integrations and address unique industry workflows, leading to higher customer retention rates compared to horizontal SaaS products. The vertical SaaS market is valued at $94.86 billion, with AI and embedded fintech being key technologies driving automation and new revenue streams within these niche markets. Managing a side project while employed requires disciplined time management. Many successful side-hustlers advocate for waking up early to dedicate 1-2 focused hours to the project before the full-time job begins. Techniques like time-chunking, using the Pomodoro method, and meticulously planning tasks using tools like Trello can help maintain progress. It is also important to schedule breaks and downtime to avoid burnout and maintain the enjoyment of the project. The transition from a stable enterprise job to the startup world is not without risk, and not all stories are of overnight success. For every viral success, there are many who struggle to find product-market fit. One senior engineer who left a $200,000 job at Google to build a SaaS product found himself with only $147 in monthly recurring revenue after 18 months. His story underscores the importance of validating an idea with potential customers before writing a single line of code.
