Over the past year, I've had 12 SaaS ideas that felt worth pursuing.

You know the feeling. You're in the shower, or walking the dog, or half-asleep, and suddenly: "Wait. What if there was a tool that..."

Historically, I'd either: a) Get excited, start building, lose steam after 2 weeks b) Add it to a notes app where ideas go to die c) Talk myself out of it before doing anything

This year, I tried something different. I scored each idea systematically, using the same framework, before writing any code.

Here's every idea, how it scored, what I learned, and the patterns that emerged.

The 12 Ideas

Idea #1: AI Meeting Notes for Sales Teams

The pitch: Record sales calls, auto-generate summaries, track commitments, update CRM.

| Dimension | Score | Reasoning | |-----------|-------|-----------| | Market | 8 | Sales teams spend $50B+ on tools, clear budget | | Competition | 3 | Gong, Chorus, Fireflies, Otter—massively funded | | Technical | 6 | Doable, but reliable transcription is hard | | Monetization | 8 | Clear B2B value, existing budget line items | | Personal Fit | 4 | Never worked in sales, don't know the workflows | | Timing | 7 | AI transcription just got good enough |

Total: 5.85

What killed it: Competition score. The space has multiple $100M+ funded companies. Even if I built something great, I'd be fighting Gong's marketing budget.

Lesson: Big markets attract big players. "There's room for everyone" is usually a lie.


Idea #2: Budget Tracker for Freelancers

The pitch: Simple income/expense tracking designed for solo freelancers, not accountants.

| Dimension | Score | Reasoning | |-----------|-------|-----------| | Market | 6 | Millions of freelancers, but fragmented | | Competition | 5 | Wave, FreshBooks, but they're complex | | Technical | 9 | Standard CRUD app, bank API integrations | | Monetization | 4 | Freelancers notoriously cheap, race to bottom | | Personal Fit | 7 | Been freelance, understand the pain | | Timing | 5 | Not new, not trending |

Total: 5.85

What killed it: Monetization score. Freelancers will use free tools forever. The successful players (Wave, FreshBooks) monetize through payments processing and upsells, not subscriptions.

Lesson: Your target customer's willingness to pay matters more than your product quality.


Idea #3: Developer Portfolio Generator

The pitch: Auto-generate beautiful portfolio sites from GitHub activity + LinkedIn data.

| Dimension | Score | Reasoning | |-----------|-------|-----------| | Market | 5 | Mostly juniors and job-seekers, small market | | Competition | 6 | GitHub profile, personal sites, LinkedIn suffice | | Technical | 8 | GitHub API, templating, straightforward | | Monetization | 3 | One-time purchase at best, hard to justify subscription | | Personal Fit | 8 | Developer, understand the need | | Timing | 5 | Remote hiring peaked, market normalizing |

Total: 5.55

What killed it: Monetization and market size. The people who need portfolios most (juniors) have the least money. Seniors don't need them—their work speaks.

Lesson: If your target customer can't afford your product, no amount of product excellence helps.


Idea #4: Cold Email Sequence Builder

The pitch: AI-powered cold email generation with A/B testing and deliverability optimization.

| Dimension | Score | Reasoning | |-----------|-------|-----------| | Market | 7 | Sales teams, agencies, founders—proven demand | | Competition | 4 | Lemlist, Apollo, Instantly—well-funded, feature-rich | | Technical | 7 | Email APIs, LLM integration, deliverability monitoring | | Monetization | 8 | Clear ROI story, existing budget categories | | Personal Fit | 5 | Have done cold outreach, not passionate about it | | Timing | 6 | AI adds new angle, but crowded |

Total: 6.10

What killed it: Competition + personal fit combo. The space is red ocean, and I'd need to love the problem to persist through the grind.

Lesson: Competitive markets require obsession. If you're "meh" about the problem, you'll quit.


Idea #5: SaaS Idea Validation Tool

The pitch: Systematic scoring, competitor research, market analysis—all in one place for founders.

| Dimension | Score | Reasoning | |-----------|-------|-----------| | Market | 6 | Solo founders, indie hackers—passionate but niche | | Competition | 7 | Mostly spreadsheets, no dominant tool | | Technical | 8 | Web app + AI integrations, in my wheelhouse | | Monetization | 7 | Founders will pay for tools that save time | | Personal Fit | 10 | This IS my problem, I'd use this daily | | Timing | 8 | AI makes research 10x faster now |

Total: 7.45

What made it win: Personal fit was a 10. I was living the problem. Every time I had an idea, I wished this existed.

Lesson: Personal fit isn't just nice-to-have. It's what sustains you through the inevitable hard parts.


Idea #6: No-Code Internal Tool Builder

The pitch: Retool/Appsmith but simpler, for non-technical ops teams.

| Dimension | Score | Reasoning | |-----------|-------|-----------| | Market | 8 | Enterprise internal tools, massive market | | Competition | 2 | Retool ($200M+ funding), Appsmith, Airplane | | Technical | 5 | Complex—need databases, permissions, integrations | | Monetization | 8 | B2B, seats-based, proven model | | Personal Fit | 6 | Built internal tools, understand the space | | Timing | 6 | Category is mature |

Total: 5.60

What killed it: Competition score destroyed it. Retool alone has 200+ engineers. I'd be competing with an army.

Lesson: "Simpler version of X" only works if X is truly overbuilt. Retool isn't.


Idea #7: AI Code Review for Solo Devs

The pitch: Get senior engineer-quality code reviews on your PRs, without a team.

| Dimension | Score | Reasoning | |-----------|-------|-----------| | Market | 7 | Solo devs, small teams, bootcamp grads | | Competition | 5 | Some players, but none dominant | | Technical | 7 | LLM integration, GitHub API, manageable | | Monetization | 6 | Devs will pay for learning/improvement | | Personal Fit | 9 | Miss code reviews, would use constantly | | Timing | 9 | LLMs just got good enough for this |

Total: 7.10

Why it's strong: Timing + personal fit. LLMs crossed the quality threshold in 2024. The problem exists. No one's nailed the solution.

Lesson: Sometimes you're waiting for technology to catch up to the idea. Timing matters.


Idea #8: Newsletter Analytics Dashboard

The pitch: ConvertKit/Substack analytics are basic. Deep dive into what content performs.

| Dimension | Score | Reasoning | |-----------|-------|-----------| | Market | 5 | Newsletter creators, growing but still niche | | Competition | 6 | Basic analytics built into platforms | | Technical | 6 | Need API integrations with every platform | | Monetization | 5 | Creators have limited budgets | | Personal Fit | 6 | Run newsletters, care about analytics | | Timing | 6 | Newsletter trend still growing |

Total: 5.65

What killed it: Monetization + market size. Creators with small lists can't afford tools. Creators with big lists have sponsors or are on enterprise plans with better analytics.

Lesson: The middle market (too big for free, too small for enterprise) is often a desert.


Idea #9: Micro-SaaS Directory

The pitch: Curated directory of profitable micro-SaaS with revenue data, tech stacks, founder stories.

| Dimension | Score | Reasoning | |-----------|-------|-----------| | Market | 4 | Very niche, mostly aspiring founders | | Competition | 5 | Indie Hackers, Twitter threads, scattered info | | Technical | 8 | Content site, manageable | | Monetization | 4 | Directories monetize poorly, advertising is dying | | Personal Fit | 7 | Love the space, would enjoy curating | | Timing | 5 | Not new, not trending |

Total: 5.30

What killed it: Monetization. Directories make money through ads (declining), sponsorships (unreliable), or premium tiers (hard to justify). The business model is broken.

Lesson: Business model viability matters as much as product viability.


Idea #10: Customer Feedback Aggregator

The pitch: Pull reviews from G2, Capterra, Twitter, Reddit—unified sentiment dashboard.

| Dimension | Score | Reasoning | |-----------|-------|-----------| | Market | 6 | Product teams, customer success teams | | Competition | 3 | Medallia, Sprinklr, Qualtrics—enterprise giants | | Technical | 6 | Many APIs, sentiment analysis, data normalization | | Monetization | 7 | B2B, clear value prop | | Personal Fit | 5 | Understand the need, not passionate | | Timing | 5 | Stable market, no new catalyst |

Total: 5.35

What killed it: Competition. The enterprise players have this locked. Going SMB means competing on price with razor margins.

Lesson: "Enterprise product but simpler/cheaper" rarely works. Enterprise buyers want enterprise features.


Idea #11: Changelog as a Service

The pitch: Auto-generate changelogs from Git commits + PRs, publish beautiful update pages.

| Dimension | Score | Reasoning | |-----------|-------|-----------| | Market | 5 | SaaS companies, dev teams—specific use case | | Competition | 6 | Beamer, LaunchNotes, Canny—but none perfect | | Technical | 7 | GitHub integration, templating, webhooks | | Monetization | 6 | B2B, but low priority purchase | | Personal Fit | 6 | Would use, not obsessed | | Timing | 5 | Not new |

Total: 5.80

What killed it: Low priority purchase. Changelogs matter, but they're rarely someone's #1 problem. Hard to sell "nice to have."

Lesson: Products solving #5 priority problems compete with "do nothing" more than competitors.


Idea #12: AI-Powered PRD Generator

The pitch: Turn rough ideas into structured product requirement documents using LLMs.

| Dimension | Score | Reasoning | |-----------|-------|-----------| | Market | 6 | PMs, founders, product teams | | Competition | 5 | Notion AI, generic LLMs, but no specialized tool | | Technical | 7 | LLM prompting, structured output | | Monetization | 6 | PMs have budgets, but varies | | Personal Fit | 8 | Write PRDs constantly, would love this | | Timing | 8 | LLMs just became capable enough |

Total: 6.55

Why it's interesting: Could be a feature of the validation tool (#5), not a standalone product. Integration potential.

Lesson: Some ideas are better as features than products.


The Patterns That Emerged

After scoring 12 ideas, clear patterns appeared:

Pattern 1: Competition Is Usually Underestimated

8 of 12 ideas died primarily because of competition. I kept thinking "I can build something better" until I researched who I'd be competing against.

The fix: Research competitors FIRST, before falling in love with the idea.

Pattern 2: Personal Fit Predicts Persistence

The ideas I was most excited about (#5, #7) weren't necessarily the biggest markets. But they were problems I genuinely cared about solving.

The fix: Weight personal fit heavily. You'll need that enthusiasm in month 8 when nothing's working.

Pattern 3: Monetization Requires Existing Budgets

The ideas with clear monetization (#1, #4, #6) all targeted customers who ALREADY spend money on similar tools. The ones with weak monetization targeted customers who historically don't pay.

The fix: Don't try to create a new budget category. Capture an existing one.

Pattern 4: Timing Creates Windows

#5 and #7 both benefited from AI timing. The ideas weren't new, but the enabling technology just matured. That's a window.

The fix: Ask "why now?" for every idea. If there's no good answer, the timing might be wrong.

Pattern 5: Ideas Cluster Into Themes

Looking at my 12 ideas, they cluster:

  • Developer tools (3)
  • Sales/marketing tools (3)
  • Creator tools (2)
  • Internal tools (2)
  • Founder tools (2)

That clustering revealed something about my interests and expertise. The founder tools cluster is where I have real insight.

The fix: Notice your idea patterns. They reveal where you should focus.

What I'm Building Now

I went with Idea #5 (SaaS Idea Validation Tool), incorporating elements of #12 (PRD generation) as a feature.

Why?

  • Personal fit is a 10 (I use it daily)
  • Timing is favorable (AI enables faster research)
  • Competition is manageable (no well-funded dominant player)
  • Monetization path is clear (founders pay for tools that save time)
  • I can be customer zero

Three months in: 200 beta users, positive feedback, early revenue. Validation validated.

The Meta-Lesson

Scoring ideas isn't about finding the "best" idea objectively. The best idea for me isn't the best idea for you.

It's about:

  1. Forcing honest evaluation (no more "I'll just build and see")
  2. Comparing ideas systematically (not just gut feel)
  3. Identifying fatal flaws early (before you've invested months)
  4. Understanding why (not just which idea, but why it wins)

The scoring framework killed 9 ideas I might have otherwise wasted time on. It surfaced 3 worth pursuing. It gave me confidence to commit.

That's not a guarantee of success. But it's better than random selection.

Your Turn

You probably have ideas sitting in your notes right now. Maybe 5. Maybe 20.

Here's what I'd suggest:

  1. List them all (no filtering yet)
  2. Score each across the 6 dimensions
  3. Kill everything below 5.5 (ruthlessly)
  4. Deep-dive the survivors
  5. Pick the one with highest total AND highest personal fit
  6. Commit to validating it properly

The scoring takes a weekend. It could save you a year.
