Solo-run BasinCheck reaches $895 verified MRR

Founder Jacob Szyszka runs BasinCheck for U.S. oil-and-gas, construction and other OSHA-regulated contractors with roughly 20 to 300 workers, combining checklists, photos, signatures, corrective actions and OSHA 300/300A records in an offline-capable mobile product. TrustMRR showed $895 verified MRR, five active subscriptions and $5,576 all-time revenue on October 19, so a handful of B2B customers already produces real cash flow. Current plans are $149, $299 and $599 a month with unlimited users and usage tiers based on monthly field records; acquisition includes a seven-day trial, free JSA and permit tools, industry-association participation and founder-led outreach. The leverage comes from a narrow niche, high contract value and software delivery. The limits are equally clear: few customers make revenue lumpy, compliance trust is demanding, and onboarding, support and custom work can still consume the founder's time.
