1Lookup
👤 Robby Frank (Runs Momentum Labs' SaaS portfolio. Sells 1Lookup to VoiceDrop's cold-outreach users, who waste budget on bad phone numbers.)🌐 site𝕏
A self-taught founder bundled phone, email and IP validation into one pay-per-use API — bootstrapped past $2M ARR.
Will it work? · our read
Quietly profitable. A crowded data-API space, but pay-per-use pricing and one-call simplicity win SMBs the big vendors overprice. Stripe-verified near $199K MRR, bootstrapped, fielding $10M offers.

TrustMRR — 1Lookup: Stripe-verified MRR and $4M+ lifetime revenue1lookup.io — product and positioning1lookup.io/pricing — universal-credit plans, $99-999/mo1lookup.io/about — founder Robby Frank, Momentum Labs studio
Revenue is Stripe-verified via TrustMRR (first-party, not audited) = STATED, verified. MRR hovers near $199K (read $198,843 and $199,736 across two loads on 18 Jul 2026), all-time $4.09M, about 650 active subscriptions; a live dashboard, so figures drift. Founding date is ambiguous: TrustMRR's Stripe data starts Jan 2022, but 1Lookup's about page frames it as a 2025 Momentum Labs product — likely a rebrand/relaunch of an existing API; I used the revenue-verified 2022 start. Pricing ($99-999/mo, 1 credit per core check, credits roll over 3 months) is from the live pricing page I opened. Data feeds are licensed, not owned. '#1 tool' is the company's own marketing claim, not verified. Founder Robby Frank confirmed on the about page; @robbyfrank X account is the social linked from TrustMRR (couldn't load it directly — X returns 402 to bots). $10M asking price / offers are from the TrustMRR acquire listing. Founder.note's studio claim is sourced from 1lookup.io/about ("a Momentum Labs product" that "builds and scales a portfolio of software products"); the VoiceDrop audience targeting is from 1lookup.io's own homepage ("Telemarketing & Outreach" section: "Check your numbers with 1Lookup before you send"). VoiceDrop itself is confirmed a separate company (AI Group LLC, San Diego, per voicedrop.ai's own footer) that 1Lookup cross-promotes to, not a Momentum Labs product. We never score you.
