Founders obsess over the symbol and treat the letters as packaging. This is exactly backwards for how a brand is actually consumed. Your customer meets your typography hundreds of times a day: the website, the invoice, the email signature, the app, the deck. The symbol makes a cameo. The type does a full shift, every day, unsupervised.
What a type pairing actually does
A logo's typography carries three signals whether you chose them or not. Weight signals confidence. Width signals stability or speed. Detail signals craft or efficiency. A heavy slab serif says durable and planted. A light extended sans says engineered and expensive. A rounded sans says friendly, approachable, and, past a certain roundness, inflatable. You do not get to opt out of these signals. You only get to pick them on purpose or by accident.
The pairing, heading face plus body face, is where consistency is won or lost. One face for display, one for reading, with clear rules about which appears where. That is a system. Three faces is a negotiation. Five is a ransom note.
Custom, licensed, or free
You do not need a bespoke typeface. You need to know what tier you are in. Free fonts from the big libraries are genuinely good now, and their real cost is ubiquity: Montserrat is on roughly every third startup site, which caps how ownable it can ever be for you. A licensed retail face costs real money and cuts the crowd dramatically. A modified wordmark, where a designer adjusts a few letterforms of an existing face, buys you legal and visual ownability at a fraction of bespoke cost. That middle path is the underrated one.
The fastest tell of a template brand is not the icon. It is a wordmark set in an unmodified free font with default letterspacing.
The boring mechanics that matter
Letterspacing at logo size is not the same as letterspacing in a paragraph. Marks set at display sizes almost always need tighter spacing, and then need it loosened again for the tiny lockup. Check the wordmark at both extremes. Check the kerning pairs your name actually contains: an AV, a To, an ry. Check that the numerals match, because your pricing page is typography too, and nothing undermines a confident brand like lining figures wobbling next to oldstyle ones.
None of this is glamorous. All of it is visible, hundreds of times a day, to everyone you are trying to convince.
