Startups grow up fast. Your verification codes should too.
Instead of tying critical logins to one founder's phone, use a dedicated, non-VoIP, real-SIM US number that your whole startup can share. JoltSMS gives you a shared inbox, notifications, and Team Access so verification codes are a team asset—not a personal liability.
- Keep bank, cloud, and SaaS codes tied to the company
- See all verification SMS in one shared inbox
- Route codes to Slack/Discord/Email/Webhooks
- Control access with Owner/Manager/Viewer roles
All your verification codes in one shared inbox.
How startups accidentally make one phone a single point of failure
In most startups, the first accounts get created on whoever is moving fastest—usually a founder or early engineer. Their personal phone number ends up attached to banks, cloud providers, ad accounts, and SaaS tools. It works… until they're offline or no longer in that role.
| Problem | What it looks like for a startup |
|---|---|
| Founder phone lock-in | Everything (AWS, Stripe, bank, domains) is tied to one person's phone number. |
| VoIP mismatch | Cheap "second number" apps work for calls but get rejected or don't receive verification SMS. |
| Re-verification surprises | Months later, a platform asks to confirm the number again—but that SIM, phone, or app is gone. |
| Scramble for codes | People DM each other "Can you send me the code?" at the worst possible time. |
| No clear ownership | Nobody is sure which numbers are used where, or who should manage them. |
Turn verification from a personal phone problem into a company system
JoltSMS gives you a dedicated, non-VoIP, real-SIM US number that belongs to your startup, plus tools to share and manage it as you grow.
- Real-SIM, non-VoIP US numbers that work where many VoIP ranges don't
- Long-term rentals so you can keep using the same number through re-verification cycles
- Shared inbox so the founding and ops team see every code
- Notifications to Slack, Discord, Email, Webhooks so nobody waits on a screenshot
- Team Access roles so you don't over-share billing or cancellation rights
Label each number by purpose—Stripe, AWS, Bank, Ads, and more.
Common ways startups use JoltSMS
Founders centralizing critical logins
Move bank, cloud, domain, and core SaaS logins off personal phones. Use a single JoltSMS number as the "company verification phone."
Growing teams sharing more accounts
As you add engineers, marketers, and ops, they all need access to codes. JoltSMS inbox + notifications keep codes visible to the right people.
Preparing for hiring, fundraising, and exits
When roles change, you don't have to untangle who owns which phone. The company keeps control of verification numbers as people come and go.
How a startup usually rolls out a "company verification number"
Rent one JoltSMS number as your company verification line
$50/month for a dedicated non-VoIP, real-SIM US number. Optional: choose a preferred area code.
Label and document it
In JoltSMS, label it "Company Verification" or "Core Accounts." Note in your internal docs which accounts should use it (banks, clouds, Stripe, etc.).
Use it when signing up for critical services
When a service asks for a phone for verification, use the JoltSMS number instead of a personal phone.
Watch codes in the inbox and Slack
Founders and ops watch the inbox, plus notifications in Slack/Discord/Email. Whoever needs the code can grab it without DM'ing someone's personal phone.
Keep it active and add more numbers as you grow
As the company scales, you can add dedicated numbers (e.g., "AWS Prod", "EU entities") and keep the original for legacy accounts.
Let founders, ops, and devs share access without sharing phones
The same JoltSMS number and inbox can serve multiple roles in your startup. You don't have to choose between security and convenience.
- Founders keep ownership via the Owner role
- Ops and engineering get Manager access for endpoints and rules
- Finance, advisors, or auditors can be Viewers with read-only access
- Up to 10 team members per number, with invites that expire after 7 days
Get verification codes where your team already lives
Early teams live in Slack and Discord. JoltSMS plugs into those tools so codes show up where people are already talking and working.
- Slack – send codes to a #security, #founders, or #oncall channel
- Discord – ideal for dev-first or remote teams that live there
- Email – notify founders or finance when sensitive accounts change
- Webhooks – log events in your own tools or dashboards
When a single number isn't enough anymore
Many startups begin with one company verification number. As things grow more complex, it's often worth adding one or two more to keep risk and ownership clean.
| Growth stage | Suggested setup |
|---|---|
| Very early (2–5 people) | One number for all critical accounts ("Company Verification"). |
| Growing (5–20 people) | One number for financial accounts (Stripe, PayPal, banks) and one for cloud/dev (AWS, GCP, GitHub). |
| Scaling (20+ people) | Dedicated numbers for core groups: Finance, Cloud & Infra, Marketplaces/Apps, etc., each with its own Team Access setup. |
FAQ for startups
Yes—most startups begin with a single company verification number and add more as they grow or as accounts become more critical.
