Automates sales follow-up across email and calls, turning routine outbound work into a recurring per-seat SaaS product.
1,000 customers · about $90 average monthly spend per user
The founder used the prior business’s proceeds and his own sales workflow to finance a focused outbound tool, then sold the product by doing the same investor outreach he was automating.

Oleg Campbell launched Reply.io in 2015 after putting an earlier QR-code business on autopilot. That earlier company had topped out at $150K annually, and he redirected money from it toward a larger opportunity: software that replaced routine sales work with automation. He put roughly $30K into Reply, hired two Ukrainian developers, and led marketing and sales himself. The product began with email sending and follow-ups, then added the ability to initiate phone calls, with a broader goal of automating more of the path to a sales meeting. At the time of the interview, Reply had 1,000 customers, 34 employees and $100K in monthly revenue. Plans ranged from $25 to $120 per user, with average spend near $90 monthly. Campbell described four profitable months and an operation close to break-even because most profit was reinvested. The interview places sales in Canada and development and marketing in Ukraine; the team included 15 developers. These are historical founder-reported figures, not current operating metrics.
Campbell took responsibility for marketing and sales while two developers built the product, so early customer discovery sat close to product development.

Data credibility: Oleg Campbell, Reply.io’s founder, reported the customer, revenue, pricing, team, growth, and profitability figures in the interview. The figures are historical self-reports; the interview provides no third-party audit or independently verified dashboard.
The first dollars came from selling Reply as subscription software, with plans priced between $25 and $120 per user each month. Campbell put average spend at roughly $90 per month, making the value proposition legible to a sales team: pay for a seat that handles repetitive outreach and follow-up.
Reply’s growth loop connected product usage, customer value, and the founder’s own outbound motion. Campbell said he used his software to contact investors and met about 15 investors over three weeks, turning the sales workflow into a practical demonstration.
Campbell’s first company taught him that a product can plateau when its underlying market loses momentum: the QR-code product reached $150K annually, then stopped finding room to expand. For a sales automation founder, a quiet launch should trigger direct diagnosis rather than a larger feature list.
