If you’ve built software long enough, you remember when zero-to-one meant long planning cycles, heavy emotional investment, and painful rewrites. In 2026, that definition has changed dramatically. Building from scratch is no longer a months-long commitment. It’s a rapid loop of experimentation, feedback, and refinement measured in hours, not weeks.
In this episode of SaaS That App: Building Tech-Enabled Businesses, Vinay Rao, Co-Founder and CTO of Elvin, joined Aaron Marchbanks and Justin Edwards to unpack how AI has fundamentally reshaped early-stage product development. From AI-assisted coding to agent-driven workflows, Vinay shares how modern builders can move faster while making better decisions.
Zero-to-One Is Finally Fun Again
One of Vinay’s most striking observations is how emotionally different early-stage building feels today. When features can be prototyped in a day or two, there’s far less pressure to be right the first time. You build, experience the results, and decide whether it’s worth keeping.
That shift removes a huge psychological tax from founders and engineers. Instead of protecting sunk costs, teams are free to explore ideas honestly. If something doesn’t feel right, it’s discarded without guilt. Speed has lowered the cost of curiosity.
A Workflow That Feels Like a Team
Vinay’s personal setup reflects how solo builders can now operate like small teams. Cursor sits at the center of his workflow, especially its plan-and-build modes, which allow him to pressure-test architecture decisions before committing to code.
For small, well-defined tasks, he assigns tickets to AI tools like Devin, treating them exactly like junior developers. Clear instructions matter. Ambiguity does not. Visual bugs, layout fixes, and simple refactors are perfect candidates.
On top of that, automated code review tools such as CodeRabbit and CodeAnt AI scan pull requests for issues ranging from critical errors to minor nitpicks. By the time Vinay reviews code himself, the obvious problems are already resolved. The result is faster merges and fewer downstream surprises.
Why Context Beats Clever Prompting
When it comes to prompting, Vinay’s advice is refreshingly practical. Great results don’t come from fancy prompt tricks. They come from context. AI systems perform better when you explain the goal, the constraints, and what success looks like.
To remove friction, Vinay often uses voice tools like Superwhisper to talk through his thinking instead of typing. Speaking naturally produces richer prompts and mirrors how humans actually reason through problems.
This philosophy carries directly into Elvin’s design. Users aren’t expected to write detailed prompts. They describe what they want in one or two sentences. Behind the scenes, the system constructs a full prompt, injects user context, such as location or preferences, and formats outputs so the UI can display results cleanly.
Stop Optimizing for Pennies
Saving money on AI usage can be more expensive than spending it. Stronger models cost more per query, but they often solve problems faster and with fewer retries. When you’re building with funding, even modest funding, time is the real constraint. Saving a few dollars at the cost of an extra hour of debugging is rarely a win. For Vinay, model choice is about throughput.
Moving Beyond Prompt-First Products
Elvin exists because Vinay believes prompt-first AI is a dead end for most users. Asking people to wake up and tell an AI what to do misses the point. The real value comes when systems proactively surface what matters. Instead of “How can I help?”, Elvin aims to say, “Here’s what needs your attention, and here’s what I’ve already handled.”
Final Thoughts
Vinay’s perspective highlights what building SaaS in 2026 really looks like. It’s not about replacing engineers with AI. It’s about orchestration. Builders now guide fleets of tools that plan, code, review, and test, while humans focus on judgment, prioritization, and product intuition. The winners won’t be the teams with the most tools. They’ll be the ones who move fast without breaking trust, and who design systems that feel calm instead of overwhelming.
Vinay’s Background
Vinay Rao is the Co-Founder and CTO of Elvin, an AI-powered super app designed to reduce mental noise by creating calmer, more intuitive user experiences. Based in the San Francisco Bay Area, Vinay has built his career around tackling complex infrastructure problems and turning them into products that feel simple on the surface but are powerful underneath.
