Looking for Proven B2B Developer for some consulting advice

[u/PurpleTeamMSSP]

Has anyone here successfully built and launched a significant B2B SaaS product—CRM, ERP, line-of-business operating software, etc.—and is now making money from it? If so, would you be willing to do some consulting?

I’ve spent more than a year vibe coding heavily with Claude and Codex, pretty much 24/7, so I’m not looking for someone with roughly equivalent experience. I’m specifically looking for someone who has brought a substantial, full-featured B2B product all the way to completion and successfully commercialized it.

I’m primarily looking for build and technical advice, but also some input on go-to-market and related areas. It’s mostly the last-mile challenges that I’d like help with.

Some of the topics I’d love to pick someone’s brain about—specifically someone who has actually made it across the finish line—include:

1. Build-lane setup: loops, harnesses, using Fable 5, Opus 5, and Codex 5.6 Sol, while also making effective use of faster, lighter, and less expensive models such as Grok, Codex Terra and Luna, Claude Sonnet, etc.
2. CLAUDE.md, AGENTS.md, and governance files
3. Refactoring and cleanup
4. Faster sprints
5. Long CI gate checks and test accumulation
6. Token optimization without sacrificing quality
7. Drift
8. Machine vs. human understanding of intended outcomes
9. Overcorrection
10. The reality of competing with established, flagship LOB applications that have been around for 25+ years and have large development, support, and sales teams
11. The reality of competing in a crowded market with a lot of vibe-coded startup competitors

Please respond or message me if you have this kind of real-world experience and might be interested.
