SaaS signup repair
Your marketing works. Then the signup form quietly throws it away.
The cruelest bug in SaaS is the one at the front door: traffic arrives, trials don't. Signup failures are usually silent — no error report, no complaint, just a user who tried, failed, and chose your competitor. We find the leak, prove it, and fix it. It's real client work we've done, not a hypothetical.
Silent failure is the default. That's the trap.
When a signup flow breaks, nobody tells you. The user who meets a spinning button or an OAuth error doesn't file a ticket — they close the tab. Your dashboard shows traffic; your database shows crickets; and the gap between them is money leaving quietly. Most founders discover the break weeks later, by accident, from a friend who tried to sign up.
The failure catalog is well-worn: verification emails swallowed by spam filters or a dead sender domain, OAuth callbacks broken by a provider change or an expired secret, webhooks that stopped syncing the billing state, validation that rejects legitimate emails, and the classic — a flow that works on desktop Chrome and dies on the phones half your traffic uses.
Diagnosis first: instrument, then prove it.
We start by making the funnel visible: instrumentation at every step from landing to activated account, so the leak shows up as a number instead of a hunch. Then we reproduce it — the failing provider, the vanished email, the broken step on iOS Safari — and fix the actual fault, not the symptom.
You get the before-and-after in plain numbers: signups attempted, signups completed, where they died, and where they stopped dying. It's the same measurement discipline we wire into marketing, pointed at the funnel's most expensive hundred feet.
Fixed by someone who ships SaaS, not just audits it.
This service exists because we've done the work — for clients, and on our own products. AICiteBeam, TeamAIOps, and MacroExits run signup funnels we built and watch daily; we know what a healthy one looks like from the inside. When the fix reveals a deeper problem — an auth system that needs proper social login, a billing sync that needs rebuilding — you'll get the honest scope and a flat number, not an open-ended engagement.
The usual suspects.
Ten years of broken funnels distill to a short list. Yours is probably on it.
Verification emails MIA
Dead sender domains, spam-folder exile, missing SPF/DKIM — the account that can't be confirmed doesn't exist.
OAuth callback failures
Expired secrets, changed redirect URIs, provider API shifts — the social button that spins forever.
Webhook drift
Billing events that stopped arriving, so paid users look free and free users look broken.
Mobile-only breakage
Works on your laptop, dies on iOS Safari — where half your signups actually happen.
Overzealous validation
Forms that reject real emails, real names, and real customers.
Unmeasured funnels
No instrumentation, so nobody can say where users vanish — until we add it.
Questions we hear a lot.
How do I know if my signup flow is actually broken?
The tell is a gap: traffic and trial starts moving in different directions, or a conversion rate that quietly sagged. If you can't currently see step-by-step numbers from landing to activated account, that's finding one — instrumentation comes with the repair.
How fast can you find the leak?
Diagnosis usually starts the same business day, and most leaks reproduce within the first session — broken flows tend to fail loudly once someone actually walks them on the right device. The fix is flat-quoted the moment the fault is named.
Our signup works — it's activation that's weak. Same service?
Yes. The funnel doesn't end at the account; it ends at the moment the user reaches value. We instrument and repair the whole path — signup, verification, onboarding, first use — because a completed form that never activates is the same lost customer with extra steps.
What if the fix requires rebuilding our auth?
Then you'll hear it straight, with a scoped flat quote for the rebuild — social login, account linking, session handling done properly. Sometimes the patch is right; sometimes it's a subscription to more patches. We'll tell you which, with the arithmetic.
Is this really work you've done before?
Yes — signup and auth repair for client SaaS, plus three of our own products running funnels we watch every day. This page exists because the work kept arriving, not the other way around.
