INDEX / DATA REPORT / OCTOBER 2026
MONTHLY REPORT · PUBLISHED OCT 31, 2026
Greg Isenberg's October 2026 business ideas, scored. 50% of them earned a BUILD.
In October 2026, Greg Isenberg's channel published 9 videos with 46 distinct business ideas. We scored each one against market data (competitors, search demand, modeled revenue range, how much of it AI can automate). 23 of 46 (50%) earned a BUILD verdict, against 17% across all 1,706 ideas in the catalog. The highest score of the month went to AI-Native Bookkeeping Firm (83/100).
01 · WHAT STANDS OUT
- The month scored well above the catalog. The median October idea scored 68.5; the median across the whole catalog is 40. 4 of the catalog's 18 ideas at 80+ came from this month.
- AI-run services held their own against software. Agency ideas were the largest group (12, 7 BUILD), next to SaaS (11, 7 BUILD), and the top two ideas of the month are both services: bookkeeping and lead generation for local trades.
- Agents are the theme. 13 of the 46 idea titles name agents. Several target the plumbing an agent economy needs: analytics for agent traffic, agent identity and payments, agent security.
- Only one SKIP. Compute and energy infrastructure (35/100): a huge market, but not one a small team can enter.
A caution on the comparison: these ideas are new, and part of the gap may come from how recent ideas are framed (specific, AI-first playbooks) rather than from the market alone. Scores are model estimates from public data, not financial advice.
02 · THE TOP 10
- 1AI-Native Bookkeeping Firm
BUILD · 83/100 · AI SERVICES · ARR $120K–$1.2M · AUTOMATION 8/10
A service business, not software: agents do the routine entries, people review exceptions, and clients pay a monthly retainer. Recurring revenue with a proven buyer.
- 2AI-Powered Lead Gen & Funnel Agency for Main Street Trades
BUILD · 82/100 · AGENCY · ARR $120K–$600K · AUTOMATION 7/10
Sells to plumbers and HVAC firms that already pay for ads but lose the leads. The pain is measurable, so the pitch is easy to prove.
- 3Vertical SaaS / Agent Harness for Local Service Matching
BUILD · 82/100 · SAAS · ARR $120K–$2M · AUTOMATION 8/10
The software step after a manual local-matching business proves demand: automate the workflow you already run by hand.
- 4Google Analytics for AI Agents
BUILD · 80/100 · SAAS · ARR $150K–$1.5M · AUTOMATION 8/10
Separates agent traffic from human traffic and shows what agents asked for and where they dropped off. A new measurement gap with no default tool yet.
- 5AI Physical Product Customizer (Shopify Widget)
BUILD · 79/100 · E-COMMERCE · ARR $80K–$1.2M · AUTOMATION 7/10
A Shopify widget that turns a customer's prompt into a printable 3D design and routes the order to print partners. Distribution through an app store.
- 6AI-Era Cybersecurity & Agent Access Control
BUILD · 78/100 · SAAS · ARR $200K–$15M · AUTOMATION 7/10
Security for agent-specific risks such as prompt injection and agent impersonation. The widest modeled range of the month.
- 7AI-Powered Local Service Matching Agency
BUILD · 76/100 · AGENCY · ARR $24K–$300K · AUTOMATION 7/10
Finds local supply and demand (cleaners, tutors, night nurses) in social groups and brokers the match. Low overhead, small ceiling.
- 8Domain-Specific AI Harness
MAYBE · 76/100 · SAAS · ARR $400K–$10M · AUTOMATION 8/10
- 9Elder Care & Longevity Services
BUILD · 76/100 · HEALTHTECH · ARR $150K–$3M · AUTOMATION 7/10
Products and services for older adults, a customer group most founders skip. Broad, so pick one service first.
- 10Gamma-Style Creative Agent Harness for Interior Design Pros
BUILD · 76/100 · SAAS · ARR $150K–$2M · AUTOMATION 8/10
Turns a design brief into mood boards, space plans and sourcing decks for interior designers. A narrow professional audience that already buys software.

HOW WE SCORE
Each idea is extracted from the video, then checked against live search demand and the competitors we can find, and given a BergScore (0–100) and a BUILD / MAYBE / SKIP verdict. Ideas are re-checked regularly, so live scores can move; the figures here are the snapshot of October 31, 2026. The full method and the whole-catalog numbers are in the data report; the live ranking is at /top.
