Why startups pick us
Made for teams without a platform engineer
Sending an email, verifying a phone or pricing a trade shouldn't need its own vendor and its own integration. We run that part so you can work on your product.
Affordable
Most products have a free plan, and the AI Receptionist has a 14-day trial. Paid plans are monthly, with no per-seat pricing, setup fees or annual contract.
Reliable
Messages are queued and retried automatically, domains are authenticated for you, and there is a public status page.
Secure
Encryption in transit and at rest, and API keys stored only as a hash that you can revoke at any time. We don't sell personal data.
Simple
One key, one dashboard, and SDKs for Node, Python and Go. Most teams send their first message the day they sign up.
The products
Turn on the ones you need
They all sit behind the same bearer key. Start with one and add the others later without a new integration.

Built for fintech
Set your own margin on every conversion
Set a buy and a sell margin per currency. Every conversion returns the live market rate, your customer rate, and exactly what you keep, so your app doesn't have to calculate it.
- Asymmetric rates. Charge 20% when they buy, 10% when they sell, per currency, per direction.
- Follows the market. Your margin is applied on top of live rates, so you never update prices by hand.
- 230+ currencies, fiat and crypto: USD, GBP, USDT, USDC, EURC and more.

Developer experience
SDKs for Node, Python and Go
The SDKs handle attachments, encoding and retries for you. Any other language can call the REST API directly, and if your app already speaks SMTP, point it at our relay with the same key.
$ npm i @startupaid/sdk copy
Go go get …/startupaid-goPython pip install startupaidMCP npx @startupaid/mcp
from startupaid import Client, attach_file sa = Client("sa_live_…") sa.send_email( from_="Kora Coffee <hello@koracoffee.com>", to="tolu@example.com", subject="Your invoice", body="<h1>Thanks for your order</h1>", attachments=[attach_file("invoice.pdf")], ) # SMTP too → smtp.startupaid.org:587
Pricing
Most products have a free plan, and each has its own price
Pay for the products you use and nothing for the others. Push and deep links are free at any volume, or take the bundle with every product included.
