B.efficient The 5-Tool Protocol

Disclosures

Last updated:

B.efficient is an independent guide to startup software for founders and investors. Instead of a directory of options, it publishes one short, opinionated stack per audience.

The protocol

Each stack holds at most 5 tools. A new tool only gets in by evicting an existing one, and every eviction is recorded in the eviction log with its date and reason.

Affiliate links

To stay free and ad-free, B.efficient takes part in selected referral and affiliate programs, including PartnerStack and vendors' own partner programs. If you sign up through one of those links, we may earn a commission or credit at no extra cost to you. Commissions don't decide which tools hold a slot, and a tool doesn't need an affiliate program to earn one.

Affiliated products

The site's owner has a financial interest in askOdin. For that reason askOdin never occupies a protocol slot, and it is marked “Affiliated” wherever it appears.

Scorecards

Prices, free-plan limits, and perks are checked against each vendor's own published pricing and documentation, and each scorecard carries the month it was last reviewed. Values we haven't confirmed are shown as “Review pending”. Setup times are our own estimates, not measurements. Perks are listed only when the vendor publishes them, and usually require joining through a partner accelerator or investor. Pricing changes, so check the vendor's site before you buy.
