Enterprise Workflow Rebuild Formula – Vertical SaaS
Apply the 'rebuild every enterprise workflow tool for a specific niche' framework to systematically identify and build simpler, more beautiful vertical SaaS replacements for aging horizontal tools.
01 THE IDEA
Every professional workflow tool (CRM, ticket management, design tools, email marketing, document management) needs to be rebuilt every 5–10 years as technology improves and user expectations rise. Incumbents cannot adapt fast enough. The formula: pick any workflow category, find the dominant 10–15 year old tool, identify a specific niche (real estate agents, Sri Lankan developers, sobriety coaches), and rebuild it simpler, more beautiful, and with the latest technology. Linear did this to Jira/Trello. Follow-up Boss did it to generic CRMs for realtors.
This is less a single business idea and more a repeatable idea-generation framework. The key insight is that niche focus multiplies the success probability: a generic CRM rebuild is nearly impossible, but a CRM specifically for CrossFit gym owners built by someone who runs a CrossFit gym is very achievable. The framework's power is that it produces B2B SaaS ideas with natural distribution (the niche community), high switching costs once embedded, and predictable acquisition paths when the category incumbent eventually wants to buy modern UX.

03 THE VERDICT
This is the most reliable SaaS idea-generation framework that exists — Linear, Rippling, Figma, and hundreds of others were all built on some version of this formula. The combination of lower build costs (AI), larger niche audiences (internet), and perpetually aging incumbents means the opportunity set grows every year. The key is genuine niche membership: don't build a CRM for real estate agents if you've never worked in real estate. Pick your niche first, then apply the formula.
Verdict: BUILD. Don't have the ~500 hours it takes? Get matched with a vetted builder who does — we review every brief by hand and intro you to up to 3 builders.
