PostgreSQL Startups

Phez was a Reddit clone that rewarded content creators with Bitcoin micropayments, built by Shanti, a 38-year-old Ruby on Rails developer, in summer 2015 as a side project emphasizing free speech. The project failed due to a flawed business model—lack of marketing, poor user engagement motivated only by minimal Bitcoin rewards, and spam/gaming attempts made it unsustainable. Shanti shut down the site after several months, losing approximately $29,014 in opportunity cost when Bitcoin's value surged years later.

Gymlisted was a membership management and payment processing platform for private gyms, built by Tom Zaragoza and a co-founder over 8 months of nights and weekends. Despite attempting multiple marketing strategies including cold email, social media outreach, and offering free 360 photography services, the startup failed to gain traction and achieved $0 in revenue, ultimately shutting down due to lack of market demand.

Fibery is a second brain for teams that helps companies accumulate knowledge and manage work processes in a single flexible tool. Founded by Michael Dubakov in 2017 and publicly launched in April 2020, the startup has grown to $24k MRR with 24 employees across 5 countries after discovering product-market fit in the product teams niche. The company raised $3.1M in seed funding and attributes its growth primarily to word-of-mouth from existing customers and community validation through content marketing.

Savvy Cal is a bootstrapped scheduling SaaS founded by Derek Reimer that crossed $20k MRR (~$240k ARR) as a solo founder operation. The product achieved its strongest growth month in October after the initial January 2021 product launch, with Derek crediting a strategic product launch with marketing consultant Corey Haynes. Derek is now planning his first engineering hire while maintaining a lean operation with outsourced support and marketing.

Tyler Tringus built Stormapper, a store locator SaaS for e-commerce businesses, in just 36 hours on a flight from San Francisco to Buenos Aires. He leveraged his year of freelance experience with Shopify store owners to identify the problem and immediately land paying customers by emailing existing clients. Within five years, Stormapper crossed $25,000 MRR through a combination of B2B app store listings and organic SEO, while maintaining extremely high retention and low support overhead.

Tracy Osborne built Wedding Lovely, a marketplace connecting couples with wedding vendors (designers, planners, photographers), after teaching herself Python and Django out of necessity when her co-founder fell through. The site languished for six years at $15-20k ARR while she worked on books and speaking, until she hired passionate team members and stepped back, sparking sudden growth to $60-80k ARR. Her journey demonstrates how perseverance through repeated setbacks—failed YC interviews, a lowball Etsy acquisition, burned-out solo operation—eventually pays off.

Corey Zoot is an indie hacker who left a CTO role managing 130 people to build a portfolio of bootstrapped products focused on enjoyment and passive income. His flagship product, PlaceCard.me, generates $20k annually through a simple wedding place card generator that gained traction via SEO and content marketing over six months. His newer project, Pegasus, is a Django SaaS template generating $500-1,000/month, demonstrating his strategic shift toward recurring revenue while maintaining his low-stress, breadth-focused approach.

Jen is a solo founder who built Lunch Money, a modern budgeting app targeting the gap left by outdated competitors like Mint and YNAB. Starting from a personal spreadsheet tracking multi-currency expenses while traveling, she coded a full MVP in 8 months while living in Japan, and achieved $800/month MRR as a one-person operation. She's grown to 40% of users migrating from Mint, proving there's still room for innovation in the personal finance space.

Emma is a technical product designer and entrepreneur building Velvet, a no-code infrastructure layer for onboarding, authentication, and payment processing across digital products. After selling her previous company Moonlight (which did $55k/month in revenue), she pursued an MBA at Chicago Booth while exploring multiple product ideas, eventually raising a $1.2M pre-seed round from Chicago Ventures to build Velvet, which aims to become the Shopify of digital goods.

Notion is a no-code productivity and database platform founded by Ivan Zhao in 2013. After 3-4 years of what Zhao calls "lost years" trying different product directions—initially as a developer tool—the company pivoted to positioning itself as a consumer-friendly productivity suite that hides powerful no-code building capabilities underneath. The company stayed lean and profitable, rebuilt its technical foundation multiple times, and achieved significant traction through word-of-mouth and organic adoption, reaching unicorn status without traditional venture funding.

How I AI is a new podcast launched under the Lenny's Podcast Network, hosted by Clairvaux, an AI-obsessed product leader and founder. The show features practical demonstrations of how people use AI tools like V0, Devin, and Cursor to ship faster and improve workflows, with live screen sharing and 30-minute episodes. The inaugural episode features Sahil Lavengia, CEO of Gumroad, showcasing how AI tools are enabling 40x speed improvements in feature development and driving cultural change in engineering organizations.

Airtable is a no-code platform that democratizes business app creation. Founded 13 years ago by Howie Liu, it achieved early product-led growth success and became a SaaS darling. Recently, Airtable has undergone a major transformation to become AI-native, restructuring into 'fast thinking' and 'slow thinking' teams to ship AI capabilities weekly while maintaining infrastructure stability. Howie personally uses Airtable's AI agent Omni extensively and spends significant compute resources testing AI capabilities daily.

StudyMate is a student learning platform built by Zevi Arnawitz, a non-technical PM at Meta with zero coding background, using AI-powered development tools like Cursor and Claude. The app allows students to upload study materials and generate interactive quizzes with multiple question types. Zevi developed an innovative workflow using slash commands, Claude code review, and multiple AI models working in concert to build, review, and refine features without writing code himself.

Dane Maxwell built Paperless Pipeline in 2009 as a bootstrapped SaaS for real estate transaction management. By identifying an existing pain point (agents managing paperwork inefficiently) rather than trying to create new behavior, he grew the product to 1,460 customers generating $180-185k MRR ($2.1M ARR). After stepping away years ago, the fully self-managed business continues to thrive under a CEO with 25% profit margin incentives.

Nathan Contney is an experienced serial entrepreneur who has founded or co-founded multiple startups including Inkling (a prediction market platform acquired and still operating), CityPosh (a gamified advertising platform that failed), and Draft (a writing application built as a solo founder). He now serves as CEO of HiRISE, a CRM application originally developed by Basecamp (formerly 37 Signals). Contney emphasizes the importance of the 'done is better than perfect' philosophy and building products to solve personal pain points, using cycles and momentum to maintain productivity.

Venuebook is a SaaS-enabled marketplace connecting event planners with venue managers, founded in 2010 by first-time entrepreneur Kelsey Wrecked. The company has raised over $9 million and operates with a dual revenue model: annual software fees for venue management systems and booking fees from marketplace transactions. Kelsey's unconventional approach of personally planning events to understand venue pain points led to building a sophisticated data infrastructure before launching the marketplace, ultimately achieving strong product-market fit.

Lemlist is an email automation platform that uses advanced personalization (videos, dynamic images, personalized landing pages) to improve cold email reply rates. Guillaume Mubesh built a 'very ugly beta' in 2 weeks with 100 signups, then prepared for an AppSumo launch two months later where they generated $170,000 in two weeks. They've since grown to ~$650k ARR in under two years through Product Hunt (ranked #1 product of the day), community building, LinkedIn content, and their own cold email outreach using the product.
