No engineering team to hire.
Tannto handles the design, the build, and the iteration on every two-week sprint. Your team operates the platform day to day. The five roles you'd otherwise have to hire never appear on payroll.

Sales OS is not a configured SaaS tool, a generic AI workflow, or a CRM skin. It is custom-built software, product-managed with your team, around the sales work your business wishes it could run but cannot get from off-the-shelf tools: lead research, signal monitoring, reply triage, follow-up, warm reactivation, rep-specific draft queues, CRM actions, and the workflows unique to how you sell.
Tannto builds the platform around your business, your stack, your data, your sales motion, and your team’s way of writing and working. V1 ships as a focused platform inside four weeks, then improves in two-week sprints as the team uses it.
Most companies are in one of two camps. Either your engineering team is heads-down on your own product roadmap, or you don't have one to spare. Either way, the build belongs with a team whose only focus is AI architecture combined with B2B sales operations. That's what we do, all we do.
Tannto handles the design, the build, and the iteration on every two-week sprint. Your team operates the platform day to day. The five roles you'd otherwise have to hire never appear on payroll.
V1 ships inside four weeks. Your salespeople are operating it while the in-house version of this build would still be in design review.
Sits on top of HubSpot, Salesforce, Pipedrive, or whatever runs today. Your CRM stays the system of record while we build. Some clients eventually retire it; either path is fine.
Two-week sprints from V1 onward. We add features your team will use, remove ones they won't, and evolve the platform alongside the business as it grows.
MIT’s 2025 study of 300+ enterprise AI deployments found that 95% produced no measurable P&L impact. The pattern is consistent. Most AI gets pointed at the fluffy work that nobody in a leadership meeting tracks. Summarise this email. Draft this Slack reply. Rewrite this document. None of it shows up on a number anyone cares about at the end of the quarter.
We hold a different line. AI gets built into the parts of your sales function where it shows up on the revenue line, replaces a measurable cost line, or buys back hours your team currently spends on admin nobody wants to do. CFO-reconcilable numbers. On the custom platform that means one team running the work that would otherwise have needed an SDR, an account manager, and a sales-ops contractor sitting in three seats. Each salesperson becomes an AI operator of the system. Humans stay on the 20% of work that actually closes business: the conversations, the relationships, the judgement calls. The platform absorbs the 80% that nobody enjoys.
Every business sells differently. Different markets. Different buying committees. Different buying signals. Different follow-up rules. Different tone of voice. Different CRM habits. Different handoffs between sales, operations, account management, and leadership. Sales OS is built around those specifics. Every feature has to earn its place.
Capability 01
For drafting workflows, Sales OS is built around your real examples: past emails, tone rules, banned phrases, relationship context, CRM history, account notes, and the way your team actually follows up. The goal is not to make AI sound human. The goal is to make the output sound like it came from your business, in the right context, for that specific relationship.
Week 1
We sit with you and map your sales process, your tech stack, and the highest-leverage system to build first. You leave the week with a designed V1, written down. What it does. What it integrates. What it doesn't.
Weeks 1-4
The custom platform ships to production inside four weeks. Integrated with the tools you already run. Live, working, in your team's hands by the end of week four.
Week 5+
Two-week sprints, every fortnight after V1. We add features your team will use, remove ones they won't, and evolve the platform alongside the business as it grows.
Bearcroft is the clearest example of the offer in the wild. HubSpot stayed the system of record. Outlook stayed the sending channel. Smartlead stayed in place for cold email.
Sales OS sat above them as a custom operating layer built around Bearcroft’s exact sales motion: active-hiring signals, warm-client nudges, hot-reply drafts, relationship-specific follow-ups, and daily queues the team could actually clear.
The drafting system was not generic. It was shaped around Bearcroft’s voice, examples, relationship context, banned language, and the way their team wanted to follow up.
The result: 21 meetings per month on average, roughly 35 positive cold replies per week, hundreds of warm-client check-ins and active-hiring opportunities surfaced, and no SDR hire.

Most clients pick one service line or the other. When we build the platform, the cold-outbound side can blend in if you want it to. Three shapes that can take:
Domains, mailboxes, lead generation, copy, replies, every layer. Your salespeople focus on the warm conversations that close.
Domains, mailboxes, deliverability, sequence templates, the playbook. Useful when your team wants to be hands-on but doesn't have the cold-outbound experience yet.
Useful when you already have SDRs running outreach and need the platform layer to absorb the admin so each one runs the work that would otherwise need three or four of them.
The shape gets agreed at the discovery call.
01
Role consolidation
Sales OS absorbs work that would otherwise sit across SDRs, account managers, sales operations, admin support, and sales engineering: research, routing, reminders, drafts, enrichment, triage, CRM updates, and follow-up management. Humans stay on judgement, relationships, negotiation, and closing.
02
Time-to-product
A focused V1 ships inside four weeks: one or two workflows that remove real sales drag and prove the operating model. From there, the system improves in two-week sprints around what the team actually uses.
03
Capital efficiency
Instead of hiring more people to carry manual work, Sales OS removes the repeatable parts first. Then you can decide where human capacity actually needs to be added.
V1 ships in four weeks. Two-week sprints after that. Every feature earns its place; ones that stop earning their place get removed.
A custom sales operating system is the layer your sales engineering team would have built. We design and engineer it. Your team operates it. No headcount on payroll.
