Mapping API for
Pre-Seed to Series A Startups
Ship location features in your MVP without a mapping line item in your burn rate model.
At pre-seed and seed stage, every recurring cost gets scrutinized in board decks. A metered mapping API that looked negligible in your first month of beta users becomes an uncomfortable line item the moment usage-based pricing meets real traction — right when you need runway most. Mapsi's flat $0/$15/$29 tiers mean your mapping cost is a known, board-deck-friendly number from day one through your next raise.

Built for the Questions Investors Actually Ask
"What happens to your costs if this 10×s?"
Growth tier ($29/mo, 35,000 calls/day) covers most Series A traction levels; you can point to a fixed number, not a "it depends on usage" answer.
"Are you locked into a vendor you'll need to re-platform later?"
Standard REST + GeoJSON responses mean no proprietary SDK dependency to unwind later.
"How fast can engineering ship this?"
Most teams get address search or a map view working same-day; no procurement or enterprise sales call required to get an API key.
From Prototype to Production
// Add a map to your app
const map = new maplibregl.Map({
container: 'map',
style: 'https://api.mapsi.dev/v1/tiles/styles/streets?key=your_key',
center: [-122.4, 37.8],
zoom: 12
});
// Geocode user input
const res = await fetch(
'https://api.mapsi.dev/v1/geocode?q=' + encodeURIComponent(userInput),
{ headers: { 'X-API-Key': 'your_key' } }
);
const { latitude, longitude } = await res.json();
map.flyTo({ center: [longitude, latitude] });FAQ
Do you require a company entity or business email to sign up?
No — sign up with any email, no company verification needed to start on the free tier.
What happens to our data/pricing if we get acquired or pivot?
Nothing changes automatically — plans aren't tied to a specific product or legal entity, so a pivot or cap table change doesn't require re-onboarding.
Can we start on the free tier and just upgrade in place later?
Yes — upgrading tiers doesn't require a new API key or any code change, just a plan change in the dashboard.
