Logo
Three forms, any background
The lockup, the mark alone, the wordmark alone. Choose the surface you will place it on and the right variant appears: black wordmark and blue mark on light, all white on ink and on Blitz Blue. The construction grid below sets the clear space and the minimum sizes.
At least X (the dot’s diameter) on every side, 2X when there is room. Nothing enters it: no text, no edge, no other logo.
Lockup 120px wide on screen, 30mm in print. Mark 24px, 8mm. App icon down to 16px. Below the lockup’s minimum, use the mark alone.
The lockup by default. The mark when the name is already written next to it or the space is square. The wordmark only where the mark would be too small to read.
Color lockup on white or light surfaces only. White on ink, on Blitz Blue and on dark photography with a solid plate. Black for monochrome print. Never on a busy image.
Construction grid
One unit, X, the dot
X is the diameter of the mark’s dot. Everything else derives from it: the clear space around the logo is at least X on every side (2X when the layout allows), the lockup sits on a grid of X, and the wordmark’s baseline falls on that grid. Measured on the master file, not eyeballed.
- X
- the dot’s diameter, 36 units of the 450 unit lockup, about 29 % of the mark’s height
- Clear space
- at least 1X on every side, 2X preferred; nothing enters it, no text, no edge, no other logo
- Lockup ratio
- 2.71 : 1 (450.52 × 166.32); the mark alone is a square
- Alignment
- align the mark’s optical center, not its bounding box, when the logo sits next to text or icons
| Form | Minimum on screen | Minimum in print | Why |
|---|---|---|---|
| Lockup | 120px wide | 30mm wide | Below that, the « api » drops under 10px: use the mark alone. |
| Mark | 24px | 8mm | The dot must stay a clear circle. |
| App icon | 16px | not for print | Favicon, avatars, tab icons: the square carries the mark. |

App icon
The mark on a blue square
This is how BlitzAPI appears as an avatar, a favicon and an app: the white mark on Blitz Blue, always a full square. Platforms round the corners; we never do. A light version exists for white interfaces.
Color
One blue, and the quiet around it
The palette is read from the site’s own tokens, so this page cannot drift from the product. Click a swatch to copy its hex. There is no red in the brand: uncertain states use amber and verified states use green, both only inside visuals.
Typography
Geist, Inter Display, Geist Mono
Headings in Geist medium with negative tracking, body in Inter Display, technical labels in Geist Mono, uppercase and letter-spaced. Three open-source families. The lines below are editable: type your own words to see them set.
Every company. Every buyer. Every hiring signal.
One API key, and the whole B2B market answers like your own database.
[ 65M+ COMPANIES · 550M+ PROFILES ]
Visual language
Signs, not pictures
BlitzAPI shows data the way it exists: as signs, fields, flows and records. No stock photos, no illustrations of people at desks. The rules below make a visual recognizable as ours before the logo appears.
Diagrams, assets and signatures drawn from the same grammar replace photography. Identity assets (logos, portraits, client marks) are the only pictures.
Blitz Blue does one job at a time: the mark, a link, the accent segment of a headline, a primary action. Never two blues, never a gradient.
Facts and labels live in Geist Mono uppercase, often in brackets: [ 65M+ COMPANIES ]. It is the voice of the machine inside the page.
Cells separated by 1px rules, one outer border, no radius, no shadow. Structure is drawn with lines, not with depth.
A headline set in Geist can carry a segment in Inter Display blue. It marks what matters, once per title.
Movement is a parameter, never a narrative: a pulse, a progress, a flux, a dash. It respects reduced-motion and never carries information on its own.
Patterns and visuals
The Blitz grid, and the social card
The blueprint grid is the ground of every BlitzAPI visual: 24px cells, dots tinted with the accent or hairlines in ink, on surface. Tileable SVG and 2x PNG. The social card is rendered from a vector source with the real typefaces; the same source produces the site’s link preview. More visuals will join this gallery.

BlitzAPI is the API-first data engine for GTM builders.
We don’t give you another black box. We give you the blocks to build your own: companies, people, enrichment, verified emails, jobs, identity, TAM and signals.
High-throughput, unlimited by design, and built to let humans and AI iterate freely.
BlitzAPI is the API-first data engine for GTM builders. Instead of another black box, it gives teams the blocks to build their own systems: companies, people, enrichment, verified emails, jobs, identity, TAM and signals. High-throughput, unlimited by design, and built to let humans and AI iterate freely. BlitzAPI is built in Paris.
Manifesto
In our words
We never wanted to build another B2B database.
We wanted to build the infrastructure behind the next generation of GTM systems.
BlitzAPI is deliberately API-first. Every feature is a block you can combine with the others to build your own workflows, playbooks and products.
Company search. People search. Enrichment. Verified emails. Jobs. Identity resolution. TAM building. Signals.
Not a black box. Not another all-in-one tool telling you how GTM should work.
You keep the control.
The unlimited model comes from the same philosophy.
AI changes how software gets built. Agents explore, retry, make mistakes and iterate. Counting credits every time they do that makes less and less sense.
So we built BlitzAPI for that world.
A technical, specialized data engine with the coverage, quality and throughput to let you try an idea, change it, and run the second idea too.
And we’re not interested in stopping at static databases.
The next step is making B2B data dynamic: live markets, hiring signals, job changes, geolocation, custom triggers and feeds that continuously update the systems you build on top.
We build the blocks. You decide what GTM looks like.

For AI tools
A brand brief your assistant can read
Paste the brief into any assistant and it knows the name, the colors, the fonts, the logo files and the rules. The manifest gives the same facts to code. Both are generated from the same sources as this page, so they never lag behind it.
The full brief in markdown: name, description, facts, colors, fonts, logo files, rules, founder, links.
The same facts as a manifest, for code, design tools and agents. Every asset with its absolute URL.
Use the BlitzAPI brand. The name is written BlitzAPI, one word. Tagline: Unlimited B2B Data Infra for GTM Builders. Positioning: the API-first data engine for GTM builders; blocks, not a black box; unlimited by design, built for humans and AI to iterate. Accent blue #0055fe, ink #201e1d, surface #f5f5f4, rules #e2e0df. Headings in Geist medium with negative tracking, body in Inter Display, technical labels in Geist Mono uppercase. No red, no shadows, no rounded cards: 1px rules and closed grids on a faint 24px blueprint grid. Signs and diagrams instead of pictures. Logo files: https://blitz-api.ai/brand/logo/ (blitzapi-logo.svg on light, blitzapi-logo-white.svg on dark, blitzapi-app-icon.svg for avatars). Full brief: https://blitz-api.ai/brand/brand.md
Antoine Blitz is the founder of BlitzAPI, the API-first data engine for GTM builders. He builds in Paris.
Antoine Blitz builds the data layer he always wanted as a growth engineer. After years of assembling go-to-market systems for B2B teams on fragmented tools, stale databases and credit-metered products, he founded BlitzAPI in Paris: not another database, but the infrastructure behind the next generation of GTM systems. Companies, people, verified emails, jobs, identity and signals, as blocks, unlimited by design, so that humans and AI can try an idea, change it, and run the second one too. He runs product, engineering and go-to-market hands-on and writes the documentation himself. His conviction fits on one line: we build the blocks, you decide what GTM looks like.
