About Holdfast
An independent engineering practice for small software businesses: the people who build them, buy them and depend on them.

How Holdfast works
Independent
No referral fees from either side of a deal and no stake in whether it closes. Reports stand on their own.
Written to be used
Plain English for the decision-maker, enough detail for any engineer to act on. No obligation to hire Holdfast for fixes.
Fixed and read-only
Fees agreed up front. Access is read-only and removed when the work ends.
Talk to Robert directly
Fifteen minutes, no obligation, and a straight answer on whether Holdfast is the right fit.
