You need a bio far more often than you write one: a speaker page, a company directory, a marketplace profile, an article byline, a panel introduction. The mistake is writing each from scratch under deadline. The fix is maintaining three lengths of the same bio — short, medium, long — that stay consistent with each other, so any request is a copy-paste. Write them once with the templates below, then refresh quarterly.

The person rule

• Third person when someone else presents you: speaker pages, directories, press, panel intros. {{Name}} is a…
• First person when the reader is on your own turf: marketplace profiles, personal site, social bios. I build…
• Keep the facts identical across both voices. Inconsistent numbers across bios read as inflation.

Short bio — about 50 words

For bylines, panel intros, and anywhere space is fixed. One identity, one proof, one direction:

{{Name}} is a {{Role identity}} who {{Core thing you do, framed as value: helps B2B teams turn support data into product decisions}}. {{He/She/They}} has {{Single strongest proof: led X, built Y used by Z people, worked a decade in Field}}. {{Name}} currently {{What you are doing or focused on now}}.

Medium bio — about 100 words

For speaker pages, team directories, and marketplace profiles. Adds a second proof and a human note:

{{Name}} is a {{Role identity}} specializing in {{Specialty}}. Over {{Years}} years, {{he/she/they}} has {{Proof 1 with a number}} and {{Proof 2 — a different kind of evidence: a launch, a team built, a client outcome}}. {{His/Her/Their}} work centers on {{Professional thesis — the through-line of what you do, one sentence}}. {{Name}} currently {{Current role or focus}}, and {{one human line: writes about X, mentors Y, is happiest debugging Z}}. Find {{him/her/them}} at {{Primary link or handle}}.

Long bio — 200 words and up

For personal sites, detailed conference programs, and about pages. Structure in four paragraphs rather than one block:

1. Positioning: the medium bio's opening two sentences, expanded with who you do it for.
2. The record: your path in two or three sentences — not every job, just the arc: {{Started in X, moved into Y when Z, now focused on…}}. Include your two or three strongest quantified proofs.
3. The present: current role or practice, what problems you take on, and for whom. This is the paragraph a potential client or employer reads twice.
4. The person: credentials worth naming ({{Degree, certification, award}}) and one or two genuinely human details. One is charming; five is a dating profile.

Rules that keep bios honest and readable

• One superlative maximum, and only if checkable. Award-winning needs the award named. Visionary needs deleting.
• Numbers age; update quarterly. A bio claiming {{Years}} years of experience from three years ago quietly miscounts.
• Cut the trailing hobby pile-up unless it serves the context. When in doubt: one detail people remember beats four they skim.
• Read it aloud in the voice of a conference host. If a sentence would embarrass you spoken from a stage, it should not be written on a page.
• Keep a dated master file with all three lengths in both voices — six blocks total. Every future request becomes a two-minute task.
