Overview
Character/Brand: Mustafa Ergisi, a former data analyst from Istanbul, Turkey, with over 10 years of experience in IT, Business Intelligence, and machine learning. He is the founder of AI2SQL, an AI tool that converts natural language into SQL commands.
Implementation Timeline: Founded in 2022, launched MVP in April 2022, reached $100,000 ARR (~$8,500 MRR) by December 2023 after 15 months.
Country of Implementation: Turkey, serving global customers (B2B: banking, insurance, telecommunications enterprises; B2C: freelancers, data analysts) through SaaS platform.
Industry: AI technology, focusing on database query automation (SQL and NoSQL).
Revenue Model
Primary Revenue Stream: SaaS with subscription-based model, providing AI2SQL tool to generate and optimize SQL commands from natural language.
How AI-Generated Revenue: AI2SQL allows users (engineers and non-engineers) to input requests in English to generate accurate SQL/NoSQL commands (example: “Find customers who purchased over $1,000 in April” → SELECT * FROM customers WHERE purchase_amount > 1000 AND purchase_date BETWEEN ‘2023-04-01’ AND ‘2023-04-30’).
Pricing Model:
- Initially: $7/month (too cheap, didn’t reflect value)
- Current: Tiered pricing from $7/month (basic plan) to $30/month (advanced plan: NoSQL support, Query Optimizer, API integration)
- Free: 5 queries/month to attract trial users
Revenue:
- February 2023: $1,151 MRR with 128 paying users
- 2023: $48,000 ARR (~$4,000 MRR)
- December 2023: $100,000 ARR (~$8,500 MRR), 108% growth in one year
Additional Revenue Sources:
- Referral program: Users get discounts or free months for inviting friends, contributing ~20% user growth
- Strategic partnerships: Partnerships with data tools (like Tableau, Power BI) to integrate AI2SQL, increasing B2B value
Costs:
- Initial development: ~$2,000 (Bubble: $25/month, Google Cloud credits: $300, domain: $10, Codex API: ~$1,000)
- Operating: ~$500–$700/month (Google Cloud: $200, Bubble: $25, HubSpot: $50, Stripe: ~$100, marketing: $100)
- Total first-year cost: <del>$8,000–$10,000, generating high profit (</del>90% margin)
AI Tools and Technology Used
AI2SQL (Proprietary tool, based on Codex):
Role: Uses machine learning (OpenAI’s Codex) to convert natural language to SQL/NoSQL commands, optimizes queries with Query Optimizer

Bubble:
Role: No-code platform to build AI2SQL’s user interface and backend
Advantages: Allowed Mustafa to develop MVP in 3 months without complex coding, low cost (~$25/month)
Limitations: Performance decreases with >10,000 users/month, requires server optimization
Google Cloud Platform:
Role: Hosting, data storage, and running machine learning algorithms
Advantages: Flexible, supports free credits (~$300), handles large queries well
HubSpot:
Role: CRM and customer support via ticketing, email automation, and knowledge base
Advantages: Reduced 80% manual support work, improved user experience

Advantages: Low fees (~2.9% + $0.30), easy integration via Bubble
Google Analytics/Microsoft Clarity:
Role: Track traffic (~5,000–10,000 visitors/month), user behavior (bounce rate, time on page), and UX optimization
Advantages: Free, provides detailed data for product and marketing improvements
Implementation Process
Phase 1: Idea and Research (Early 2022):
- Mustafa, from his data analysis experience, recognized that manual SQL query optimization was time-consuming (3–5 hours/day) and error-prone
- Market research via Product Hunt, Reddit (r/SQL, r/datascience), and Indie Hackers confirmed demand for SQL automation tools
- Idea: Use AI to convert natural language to SQL, serving engineers, analysts, and non-technical users (marketing, business)
Phase 2: MVP Development (Q1–Q2/2022):
- Used Bubble to build simple interface (input request box, output SQL box) and integrated Codex API (OpenAI) for AI functionality
- Challenges: Initial accuracy only ~60%, difficult interface, algorithm failed with complex queries
- Beta testing on Product Hunt (April 2022), collected feedback from ~100 users to improve accuracy (to 80%) and UX
- Total MVP development time: ~3 months, cost ~$2,000
Phase 3: Launch and Promotion (Q2–Q3/2022):
- Official launch on Product Hunt (April 2022), ranked #5, attracted ~2,000 trial users and 128 paying users ($1,151 MRR by February 2023)
- Twitter promotion (@heyAI2sql):
- Transparent sharing: Revenue ($1,151 MRR), new features (Query Optimizer), and challenges (API cost, UX bugs)
- Direct user interaction, responding to DMs, and posting threads about SQL tips
- Content marketing: Wrote long articles (~2,000 words) about SQL optimization (example: “10 Ways to Speed Up PostgreSQL Queries”), ranked top 10 Google for keywords like “SQL optimization”
- Hacker News: Posted introduction article, received ~500 upvotes, brought ~1,000 visitors
Phase 4: Growth and Optimization (Q4/2022–Q4/2023):
- Implemented referral program: 20% discount for inviting friends, contributed ~20% new users
- Increased pricing from $7/month to $7–$30/month (tiered pricing), improved conversion rate through higher value perception
- Product improvements:
- Added NoSQL support (MongoDB, Cassandra)
- Launched Query Optimizer: Automatically suggests faster queries (30% runtime reduction)
- Integrated Google Cloud Platform to handle >10,000 queries/day
- Partnerships with Tableau and Power BI, allowing AI2SQL integration into enterprise workflows
- Automated customer support via HubSpot knowledge base, reduced 80% manual tickets
- Result: Reached $100,000 ARR (~$8,500 MRR) by December 2023, with 300+ paying customers
Results Achieved
Revenue:
- February 2023: $1,151 MRR (128 paying users)
- 2023: $48,000 ARR (~$4,000 MRR)
- December 2023: $100,000 ARR (~$8,500 MRR), 108% growth in one year

- Mustafa Ergisi’s personal brand prominent via Twitter (@heyAI2sql) and Indie Hackers, recognized in SaaS community
- AI2SQL mentioned in “AI SQL Tool Market 2024-2031” report and received 4.8/5 rating on Product Hunt
- Successfully competed with AI Query, SQLAI, and ChatGPT through specific niche (SQL/NoSQL automation) and unique features (Query Optimizer)
- Organic traffic: ~5,000–10,000 visitors/month from SEO and Hacker News
Key Lessons Learned
Main Success Factors:
Specific Niche: Solved real problem (SQL optimization) in growing market (data analytics), serving both engineers and non-engineers
Effective No-Code: Bubble enabled fast MVP launch (3 months) with low cost (~$2,000)
Smart Marketing:
- Product Hunt (#5) and Hacker News (~500 upvotes) provided initial visibility
- Twitter (@heyAI2sql) built trust through transparency (revenue, challenges) and direct interaction
- SEO (SQL optimization articles) created sustainable organic traffic (~5,000 visitors/month)
User Feedback: Refined product based on feedback from Product Hunt, Twitter, and email (example: “Saves 3 hours/day”)
Sustainable Bootstrap: No external funding, maintained control, reached $100K ARR debt-free
Creative Differentiators:
- Integrated Codex into SQL/NoSQL niche, added Query Optimizer to outperform ChatGPT (doesn’t optimize complex queries)
- Twitter transparency (public MRR, bugs) created differentiation, built loyal community
- Referral program and partnerships (Tableau, Power BI) drove organic growth and B2B adoption
Challenges and Solutions:
Lack of Deep Programming Skills: Used Bubble and Codex API, learned through OpenAI documentation and YouTube (~2 weeks)
Low Initial AI Accuracy: Refined algorithm through beta feedback, increased from 60% to >90% in 6 months
Customer Support: Automated via HubSpot knowledge base, reduced 80% manual tickets
Codex API Costs: Optimized queries, added free tier (5 queries/month) to control traffic
Competition: Targeted SQL/NoSQL niche, added unique features (Query Optimizer, NoSQL support) for differentiation
What to Do Differently:
- Hire customer support earlier to reduce pressure (currently handling ~50 tickets/week alone)
- Increase pricing earlier (from $5/month to $7–$30/month from Q3/2022)
- Invest in Google Analytics/Clarity from day one to better understand user behavior
Tips for Beginners
Find Pain Point Niche: Identify specific problems (SQL, code generation, content automation) in industries you understand (data, marketing, dev)
Use No-Code: Start with Bubble (<del>$25/month) or Webflow, learn via YouTube (</del>1–2 weeks)
Minimal MVP: Build 1 core feature (like text-to-SQL) in 1–2 months, test with beta users
Free Marketing:
- Launch on Product Hunt and Hacker News to attract early adopters
- Use Twitter to share transparent journey (revenue, bugs), build community
- Write SEO-friendly blog posts (~2,000 words) about your niche for organic traffic (example: “SQL tips”)
Referral Program: Add incentives (discounts, free months) to encourage user referrals
Free Tools: Use ChatGPT to test ideas, Google Analytics/Clarity for tracking, Stripe for payments
