Evidence without case-study theatre
Sigma Reef does not invent dramatic anonymous wins to make the page feel bigger. This page shows the proof that can be supported publicly; deeper context is shared during qualification, when it is relevant.

Pattern evidence
security-hardware launch
Sold out on launch day—the founder called to pause the campaign because the phones would not stop ringing.
A clothing security-alarm hardware brand had no customer data, no defined audience and no launch plan. Sigma Reef's founder ran market and competitor research, defined the target segment, and designed and executed the launch campaign.
- Scope: market and competitor research, target-audience definition, and a targeted launch campaign, in that order.
- Limitations stated plainly: identity withheld under the client's standing confidentiality policy, not a refused permission—this account is the founder's own engagement record, not independently audited.
used-books marketplace
Sales doubled from the first week after the integration shipped, and manual operational workload was cut roughly in half.
A used-book reseller managed inventory by hand across channels, with a broken Mercado Libre connection and sales below potential. Sigma Reef's founder integrated Mercado Libre properly and rebuilt the inventory workflow so stock stayed synchronized across channels.
- Scope: Mercado Libre API integration, WooCommerce inventory automation, and a redesigned listing-to-shipping process.
- Limitations stated plainly: identity withheld under the client's standing confidentiality policy, not a refused permission—this account is the founder's own engagement record, not independently audited.
hotel payment processor
Live since 2016 and still running today, more than 10 years later, processing payments for hotels across Argentina—the founder still uses it to charge his own customers.
A CEO needed a fast, low-cost MVP payment processor. Sigma Reef's founder integrated Authorize.net first, added Stripe the same week after the first demo, then built the approved MVP into a full production system over the following three months: error handling, reconciliation reporting, multi-tenant architecture and a WordPress plugin.
- The MVP shipped the same week it was requested; full production implementation followed over the next three months.
- Limitations stated plainly: identity withheld under the client's standing confidentiality policy, not a refused permission—this account is the founder's own engagement record, not independently audited.
