TRM not TAM, acquiring a competitor, and finding a developer co-founder

Executive overview

Bootstrappers waste time on TAM — a top-down number that's irrelevant at their scale. The useful metric is Total Reachable Market (TRM): a bottom-up estimate of how many buyers you can actually reach through the channels you'll use.

This episode also covers the hidden costs of competitor acquisitions, the real path to HIPAA compliance, and why most non-technical founders struggle without a technical co-founder.

Building a bootstrap SaaS without a technical co-founder is an 80% bad idea — the exceptions exist, but the tech debt and scaling pain are relentless.

Acquiring a competitor

• Ask first: is it worth it? Acquisitions carry cognitive, legal, transitional, and adoption costs.
• A competitor doing low MRR may not be worth acquiring even for free — opportunity cost of the transition work is real.
• Acquiring makes sense when you're at millions ARR and the target is low-to-mid six figures — pricing structures the deal as cash, seller note, or equity.
• Decide early: merge the products or run two? Running two is costly — duplicated support, marketing, and sales effort.
• Ask the seller for a migration recommendation; tie part of the sale price to customer migration percentage.
• Customer migration rate is wide — expect anywhere from 30% to 80% to switch over.
• Alternative: stop marketing the acquired app, redirect sign-ups to your product, let the legacy MRR churn out naturally over a couple of years.
• Low-switching-cost apps (e.g. scheduling links) migrate easier than high-switching-cost apps (e.g. CRMs, email marketing platforms).

HIPAA compliance for bootstrappers

• HIPAA compliance is achievable for bootstrappers — it is not the exclusive domain of well-funded companies.
• SOC 2 is expensive; HIPAA is different and more accessible.
• If you think your product needs HIPAA, it probably does — get compliant before signing customers.
• HIPAA compliance requires premium pricing: $500–$1,000/month minimum for compliant plans; $1,000–$2,000/month for outbound-led sales.
• The real question is not "can I get compliant?" — it's "does anyone need this and will they pay enough to make it worth it?"
• Practical research path: Microconf Connect community, ChatGPT as a starting framework (not final arbiter), then legal review.

TRM not TAM

• TAM (Total Addressable Market) is a top-down VC metric — the theoretical billions captured by owning an entire category.
• TAM is misleading for bootstrappers; you don't need 1% of a billion-dollar market, you need a reachable slice.
• TRM (Total Reachable Market) is bottom-up: estimate the buyers you can actually reach through two or three specific channels.
• Build TRM from search volume, Capterra/G2 rankings, Reddit/Quora/Stack Overflow answers, and in-person events.
• Think in terms of switching volume (competitors' churn) plus new entrants entering the category each month.
• Example: a market with 1,500 total customers may have only three new buyers per month — that constrains realistic growth expectations.
• Tiny Seed exits at $5M ARR require a market of only $10–50M — TAM thresholds from VC don't apply.
• TRM gives a sanity check: stop expecting 1,000 new customers per month when only hundreds are switching in your category.

Finding a developer co-founder

• Equity-only developer deals rarely work — skilled developers can bill $150/hour and won't risk that for an uncertain startup.
• "I have an idea and know the market" is not sufficient leverage; you need concrete sales skills, warm leads, or an engaged email list.
• Most developers can write code but can't make product decisions — UX, onboarding flow, and product strategy require a different skill set.
• Full-stack developers who can own an entire product exist but are not on the open market; they're running their own companies.
• Non-technical founders at Tiny Seed (~15% of the portfolio) consistently struggle with engineering, scaling, and code quality.
• Rewriting the codebase two or three times is a common pattern without a technical co-founder owning the foundation.
• Best path: fund a co-founder with a salary and 10–20% equity rather than sweat-equity-only arrangements.
• Work hour-for-hour: while the co-founder builds, the non-technical founder should be selling, doing SEO, building a launch list.
• Alternatives: learn to code, use no-code, or find a technical co-founder through communities like Microconf.

App store revenue data

• No public, aggregated data source exists for revenue or spending across app marketplaces.
• Public companies (Shopify, Atlassian, Salesforce/Slack, HubSpot, Rackspace) file S-1s and annual reports — check those for marketplace revenue line items.
• Caveat: most filings bucket marketplace revenue under "other" without breaking it out by store.
• Microconf maintains a list of ~71 app marketplaces useful for identifying step-one and step-two business opportunities.
• Doing the research manually is a moat — if it were easy, everyone would have done it.
