A focused online Gantt chart helps teams replace brittle schedules and PDF handoffs.
~6,000 customers · first customer paid $29/mo
They chose “Gantt chart software” while broader project-management terms were crowded, then earned demand before launch.

Nathan Gilmore and co-founder John started TeamGantt in 2009 after struggling with project timelines at a commercial roofing company. Their schedules lived in PDFs that had to be exported again whenever plans changed, and they could not find a simple web-based Gantt chart. They built a landing page, used a $100 Google Ads credit to test interest, and collected email signups before the product was ready. After about six months they had a basic beta; after roughly 12 to 14 months they launched and began charging. Their first paying customer, a California video company, paid $29 per month. Search content helped build an audience of 1,300 email subscribers before launch, and the founders eventually focused on the phrase “Gantt chart software” rather than competing broadly for “project management.” At interview time, Nathan reported about 6,000 customers, 21 employees, users in 180 countries, and revenue well into seven figures. He said the company remained fully bootstrapped. These figures are founder-reported, not independently audited.
For TeamGantt, the first customers came from validating a narrow problem before the full product existed.

Data credibility: Nathan Gilmore reports TeamGantt’s revenue, customer count, employee count, timeline, and customer examples in an interview. The figures are founder-reported and unaudited; the $10K MRR milestone was recalled approximately.
TeamGantt’s first dollar came from converting a beta user after the team began charging. Nathan recalled the first paying customer as a video company in California at $29 per month.
TeamGantt’s early growth compounded through a specific search category and a product that made sharing a schedule simpler than exporting repeated PDFs.
Four hours a week leaves little room for polishing features that nobody needs. TeamGantt’s founders kept their early work bounded, shipped a beta after about six months, and accepted that it was not pretty or complete.
TeamGantt is a browser-based scheduling and project collaboration product centered on Gantt charts. A Gantt chart lays tasks along a timeline so teams can see sequence, ownership, and dependencies. Nathan described the original pain at a commercial roofing company: every schedule change meant exporting another PDF, while the team wanted a shared web view. Over time TeamGantt added collaboration features such as comments, discussions, checklists, and resource views, while keeping the chart central to its identity. The transcript describes users across many industries and a newer effort to serve construction more directly. A copyable product wedge is therefore not “all project management.” It is a fast, clear schedule that several people can update without passing files around. For an MVP, make the timeline easy to create, share, and revise before building a broad suite.
TeamGantt is a SaaS business. Nathan reported about 6,000 customers, 21 employees, and revenue well into seven figures; he also described the company as 100% bootstrapped. The first paying customer paid $29 per month, and the team reached roughly $10,000 MRR around 2012 by his estimate. These are interview statements, not audited financial records. The product can charge recurring fees for active teams, with higher-value tiers for collaboration, resource planning, integrations, and construction-specific workflows. A new entrant should avoid copying historical prices without testing current buyer budgets. Offer a useful self-serve plan to reduce evaluation friction, then price team features against the coordination cost they remove. Track trial-to-paid conversion, expansion by workspace, churn by customer segment, and support burden per account. The company’s broad customer base and its emerging construction focus illustrate how a horizontal entry product can coexist with a premium vertical offer.
Our read: plan operating costs around the needs of a collaborative scheduling SaaS. The core cost centers are application development, cloud hosting, database storage, email delivery, payment processing, customer support, and sales time. Shared project data must remain reliable because teams use it to coordinate deadlines and people. Build audit history, permissions, backups, and export paths into the product early; these safeguards matter more as a schedule becomes operationally important. Start with a hosted database, background jobs for notifications, and error monitoring rather than custom infrastructure. Keep free usage bounded so dormant workspaces do not create unpriced support obligations. Measure gross margin alongside support tickets per account and infrastructure cost per active project. A construction-focused tier may justify higher service and integration costs if it can command a correspondingly higher price.
Copy the narrow positioning, early beta, direct customer feedback, and sustained search investment. TeamGantt’s founders aimed at Gantt charts instead of competing immediately for the broad project-management category. They used a landing page and a small paid search experiment to test interest, then built a basic beta and charged once people used it. A modern founder should preserve that sequence while adding fast usability tests and explicit activation metrics. Change the acquisition mix for 2026: organic search remains useful for high-intent templates and comparisons, but a new entrant should also test partner integrations and industry communities. The interview describes a construction conference where the team collected 200 leads and scheduled 40 demos in two days after building a Procore integration. That was a later, targeted event, not a guaranteed early-stage result. Choose events only after customer interviews show that buyers gather there and the demo solves a visible workflow problem.
Project scheduling is crowded, and buyers already have tools such as spreadsheets, Microsoft Project, and larger project-management suites. A new product can become a feature bundle without earning a distinct reason to switch. TeamGantt’s founder said broad positioning made messaging and product decisions difficult, then the company used customer conversion and retention patterns to identify construction as a promising segment. That is a useful discipline: compare segments by activation, conversion, retention, and support cost before committing engineering effort. Other risks include inaccurate schedules, permission mistakes, poor integrations, and long enterprise procurement cycles. A self-serve tool may acquire smaller users but still need security, onboarding, and support capabilities for larger organizations. Keep the chart workflow dependable, avoid building every requested feature, and make data export straightforward. If users create a schedule but do not invite teammates or return to update it, the product has not yet become part of the operating routine.
