OffersInBox: Async B2B Cold Outreach Response Triage & Reply Intelligence

The Problem

Indie SaaS founders on r/indiehackers consistently report that once their product gains any traction, their inbox fills with partnership pitches, reseller offers, acquisition inquiries, and vendor spam — and they have no system to triage which deserve a real reply vs. a template vs. silence. OffersInBox connects to Gmail/Outlook, auto-classifies inbound B2B outreach by intent and sender credibility, scores each thread by potential revenue impact, and drafts context-aware reply templates so founders spend under 5 minutes per week on inbound business development.

Target Audience

Bootstrapped SaaS founders doing $1K–$20K MRR who are the sole person handling all inbound business email and drowning in low-signal outreach

Why Now

AI-generated cold outreach volume has 10x'd in 2024, making every founder's inbox a noise problem at exactly the moment they have the least time to manage it.

MVP Scope

Gmail OAuth integration that classifies the last 90 days of inbound threads into 5 buckets (acquisition interest, partnership, reseller, vendor spam, press) and surfaces the top 3 threads worth replying to.

AI Angle

LLM reads full email thread context plus the sender's company LinkedIn/Crunchbase data to score genuine acquisition interest vs. AI-blasted spam with a single credibility score.

Primary Risk

Gmail API OAuth approval can be slow and the 'sensitive scopes' review adds weeks — using a Zapier/Make bridge as the MVP connection layer avoids this while validating willingness to pay.

Validation Checklist

• Post 'How do you handle inbound partnership and acquisition emails as a solo founder?' on r/indiehackers and count founders who say they ignore most of it
• Manually audit your own or a willing founder's Gmail inbox for 30 days of inbound B2B threads and publish the categorization breakdown as a tweet thread
• Launch a $0 Google Sheet template called 'Inbound B2B Triage Log' and measure how many founders download and ask for an automated version
• Run a 48-hour pre-sale for 20 lifetime licenses at $49 each on Gumroad before writing a single line of code

Who Would Pay For This

Likely buyers are founders, operators, and small teams with a recurring business process. Start with Bootstrapped SaaS founders doing $1K–$20K MRR who are the sole person handling all inbound business email and drowning in low-signal outreach and validate whether this can replace a spreadsheet, manual review, or consultant workflow.
